Modern Pivot Door

The modern pivot door is expanding the possibilities and stretching the imagination of architects and designers around the world. Modern pivot doors are not the heavy or clunky big pivoting doors that require regular maintenance just to keep them functional, like those of days gone by. No, the modern pivot door is lightweight, fully insulated, and can be guaranteed not to fail for 50 years.

modern pivot door

Sleek, modern entryways may feature large wood pivot doors as front doors that are not only hugely functional but eco-friendly and sustainable for a better world. In the past, large wood pivot hung entry doors used in exterior and interior applications were difficult to create, install, manage, and maintain over time, but not if your modern pivot door has Sing Core inside.

Sing Core offers a variety of strength, flexibility, and value to the architectural pivot door industry that cannot be achieved otherwise. The biggest and best professional pivot door companies, millworks, and high sophisticated hand-crafted custom pivot door artisans say,

“There’s just no other way to do it.”

By “do it,” they mean that you just cannot make a large modern pivot door and keep is straight and true without starting with Sing Core as the foundation of all your modern pivot doors.

If you want exterior wood doors that pivot that are fail-free pivot front doors with flawless service records that are guaranteed to remain warp-free for 50 years, then you are best advised to make sure that Sing Core is in your modern pivot door specification.

Looking for Sing Core

Many people discover Sing Core when they are scouring the vast array of resources that exist in our modern-day digital age searching for inspiration for modern pivot doors and they set out to buy a modern pivot door with Sing Core inside. It doesn’t take long for them to figure out that getting such a door is easier said than done.

While the world’s best modern pivot doors do have Sing Core inside, Sing Core does not make modern pivot doors. Sing Core does work with the professional pivot door companies, manufacturers, and artisans, providing them with the material to make these large modern entryways happen. Allowing architects and architectural door designers to spread their wings, while Sing Core brings their modern pivot door dreams to life and helps them soar.

 

Inventor, Peter Sing, uses his expertise including his unique patented and patent-pending modern pivot door technologies to create the fully lightweight, fully insulated, warp-free substrate that makes these best modern custom front entry doors possible.

How does Sing do it?

Sing’s patented solution starts with a reinforced, fully insulated, premium modern door core, then adds any variety of additional anti-warp technologies based on the size of the pivot door, the structure, the structure’s location and elevation, the orientation of the door, and the exterior skin of the door.

High Precision

And when it comes to precision, Sing’s core sports incredible tolerances of +/- .006 inch, which also supports the ability to deliver such outstanding results, truly a technological advancement in the industry.

As you may have guessed, large wood pivot doors present the biggest challenge, since natural wood grains tend to move and adjust according to changes in temperature, barometric pressure, and moisture in the air. Sing’s solution addresses these issues and cancels them out for any custom-made modern pivot door made of wood.

In this respect, Sing’s modern-day pivot doors, are true modern style doors even though Peter Sing admits he does not make modern pivoting doors. Sing says,

“We do not make the doors we are famous for. The architect specs ‘Sing Core Modern Pivot Door’ and we work with the people who are highly skilled in making our doors look and operate so good. It is a great team effort with magnificent results.”

When size matters, modern architecture is seeking solutions like Sing’s core, to deal with the challenges associated with the oversized front door issues.

How big can they be?

Up to 50 feet, or more with Sing Core.

The light weight of modern pivot doors with Sing Core inside makes custom modern pivot door installation a breeze. And the problems associated with using exterior modern pivot doors are just faint memories of the past thanks to Sing’s core, which also provides insulation for sound deadening capabilities and increased climate control.

Now you know why the best premium modern pivot doors have Sing Core specified in the architectural specifications, because if you want exterior wood doors that pivot, without having to deal with the high potentiality of failure due to warp or delamination, like they say, Sing’s core “is the only way to do it.”

Whether your modern pivot doors are single, multiples, or motorized custom-made pivot doors, you can maintain the modern appearance of strikingly new pivot doors while increasing longevity and performance in a fully sustainable manner.

Warp-free Large Sliding Barn Doors

Large sliding barn doors are an important feature in the biggest warehouses and industrial locations in the United States, from military to aerospace a big sliding barn door is often specified in the architectural designs for practicality and ease of use. But the larger the door opening the harder it is to keep these huge sliders from warping. If you cannot keep the door straight, you may have reduced access due to door failure.

Ceiling mounted barn doors 14 ft. x 3.5 ft. x 2.5 in.

For years, inventor Peter Sing’s patented warp-free sliding barn door solutions have been the answer to these massive sliding barn doors, which using his patented and patent-pending anti-warp solutions can be built lightweight, high strength, and be guaranteed not to warp for 50 years, unheard of before the invention of Sing Core.

Interior Barn Doors

As interior design has evolved, the integration of interior modern barn doors in everything from residential to commercial projects has seen rapid growth. Of course, standard-sized interior sliding barn doors do not pose much of a challenge, but if the door exceeds 8 feet tall or a 4-foot width, now you are heading into dangerous territory if you are hoping for a non-warping sliding barn door.

Warped Large Sliding Barn Doors

Regardless of the application, large sliding barn doors are going to be problematic, so much so that years ago, the biggest door companies in the USA excluded offering the large barn door from their door schedules, instructing contractors to seek out custom door makers or millworks, because they could not cover these enormous sliding barn doors with any warranty because they were destined to warp and fail not long after installation.

After a while, even the millworks started turning down jobs for large sliding barn doors for the same reason, too many service calls during the warranty period, though this did open a door for door service companies whose job it was to regularly maintain doors, though this was extremely expensive for end user of the warping big sliding barn door.

Not Faulty Design

The problem, it turns out was not with the design, as large sliding barn doors were both stylish and practical, so the architects could not be blamed. The problem is with the limitation in building materials. A dimensionally stable door could be made of a thick solid material such as solid steel, but the bigger the door gets, even solid steel will move according to changes in the environment. Sing is able to bring the ideas of the architects and designers to life in such as way as to provide a 50-year solution to such visionary ideas.

Warp-free Solution

When inventor Peter Sing introduced his warp-free technologies to the large sliding door companies, they embraced Sing’s solutions for warped large sliding doors. Thanks to Sing, they were able to get back into the oversized door market once again. According to them, in their own words. Sing’s core,

“Is the only way to build a lightweight warp-free large door.”

The only way.

Commercial Steel Barn Door

A Door is Not a Wall

It is important to learn what the core structure is made of. Doors are not the same as walls. Doors need to move repeatedly everyday while walls are permanently placed. Walls commonly use 2” x 4” framing methods which do not work well for building doors. If the structure of the door is not strong, it will not feel or sound very solid. When you close the door, there will be rattling sounds and/or it can deform over time. It is very easy to tell, all you have to do is close the door and hear how strong or solid the door is made. It may look the same, but it does not sound the same. You can tell the difference by knockings on the door, you can tell what is inside. Solid like a rick but still light like a feather when you swing the door closed. The structure of the door that makes the difference, not the door skin.

You Want a Warp-free Large Sliding Barn Door

We already know you want a large warp-free sliding barn door. How do we know? Because Sing’s email servers are filled with people asking about how they can get a sliding barn door with Sing Core inside? Unfortunately,

Sing Core Does Not Sell Doors

Even though sliding barn doors with Sing’s core inside are among the best doors in the world, Sing’s factory does not build doors. Rather, they provide the raw warp-free base materials to the door building companies and millworks who create the enormous warp-free sliding barn doors, that the inventor is credited with, even though Sing only provides the base material. So, if you really want one, just contact your favorite door builder or millwork and tell them you want a door, “with Sing Core inside.”


How to Build a Large Sliding Door

Undoubtedly, you have wondered how does Peter Sing build such large lightweight sliding barn doors that are stronger than steel pound for pound and can be guaranteed not to warp for 50 years? Following are the methods that Sing uses to build warp-free doors of any size, made of nearly any flat building material. First, the architect or door engineers, specify the door dimensions and the material that the door will be made of, and submit the specs to Sing’s True Flat Team. The team goes to work, gathering all the data necessary to predict what the challenges will be for the door. Questions like, will it be an interior or exterior door? Will it be exposed to the elements? In what geographical location will the door be installed and at what altitude? Which direction will the door face?

The team starts with Sing’s patented rigid foam reinforced torsion box core, then add additional patent-pending anti-warp technologies to compensate for exterior door skins and environmental concerns.

 


How Can You Ship Such Large Doors?

Of course, the military can do amazing things with transportation that cannot be accomplished by mere mortals, so Sing has created a modular technology that supports his 50-year guarantee. In this manner, any size of door can be built and shipped in high precision sections that are assembled on-site.

Joining a modular door shipped in sections

This saves so much on shipping and handling costs, and if the large door needs to fit in an elevator or tight doorway, not problem. High precision modular solutions are the answer. Sing Core has built many large doors that are joined on-site without any warping.

Don’t try this at home. Average dowels and even larger biscuit-joining will not prevent door warping. Let’s say you wanted to build a pair of 10’ x 20’ double barn doors that were 2-inches thick. Stacking and joining four 5’ x 10’ x 2” panels together will not be an easy task. But Sing Core has had many years of experience with oversized doors, and has been devoted to solving the common issues with larger modular doors.

If you have a good budget, high precision demand, and no issue accessing the job site then a one-piece large door panel is the way to go, if it can be shipped to your location.

Otherwise, modular door sections joined on-site will be the best option. There are two major factors to achieve high quality when building large doors. One is to make sure there is no warping once the modular sections have been joined. The second issue is maintaining a high precision joint line so that it is not noticeable. This requires a very high precision core to achieve. Sing Core is the most precision door core available, with a tolerance of ± 0.007”. It is important to be sure that the thickness of the core is within these tolerances.

Weight and Strength

Strength plays a key factor when building larger doors. Traditional door building methods may dictate that strong doors are heavy and lightweight doors are weak. Weight is a major issue with oversized doors. Heavy doors are significantly more expensive due to additional structure costs, higher labor costs, and extra shipping and handling costs. Heavy door core does not mean that it will have high strength and the larger the door is, the more strength is necessary to maintain a long lifespan.

 


What type of skin is best to build a large modular door?

Paint Grade – It is easy to hide the seams. Seams can be almost unnoticeable if modular sections are joined with a Sing Spline. If the spline is made of solid wood, it can move or warp after the moisture levels change and it will be reflected on the surface of the door. This can cause the surface of the door to crack after the seasons change.

HPL (High Pressure Laminate) – See how precise the joint is using only a Sing Spline. HPL is available in a wide variety of patterns. The best choice for HPL is a vertical pattern to help the joint blend into the surface. HPL is a good choice when ordering one of our modular oversized doors. The patterned HPL allows the joint line to be hidden in plain sight. The door can be as big as 12 feet tall and 40 feet wide without having any noticeable seams.

HPL Barn Door Joint
Metal – If it is paint grade metal, the seam can be filled with joint compound and then painted making a seamless joint. Metal doors are traditionally very heavy, but with Sing Core inside your metal door can weight roughly 1/3 of a traditional metal door. You can choose from any type of metal you would like, but our most commonly made metal doors are Aluminum or Cold-Rolled Steel. Click here to see a paint grade Sing metal door.

FRP – FRP, or Fiber-Reinforced Plastic, can be used to make very large doors and very durable doors. FRP can be smooth or have a textured surface. It is much more visually appealing and functions much better than solid wood which has potential to crack, warp, twist, and cup. Besides, solid wood weights a lot more than Sing wood stave planks. Sing wood stave planks are the ideal material to replace solid wood for such jobs as, doors, tabletops, post and beams, and many more. An advantage of choosing wood staves are that they are much more precise than solid wood because their tendency to move over time is minimal in comparison. On the other hand, wood staves are much harder to match with surrounding patterns than a wood veneer skin.

Wood Veneer – Wood veneer has an average thickness of 0.020″-0.030″ and is very difficult to hide joint line in the face of the panel. Wood veneer is often much more challenging because it is usually very thin, normally only 0.020” thick. We always suggest using thicker wood staves which are usually 0.125” thick rather than veneer. However, Sing Core has a proprietary technology to make a veneer panel seamless as large as 10′ by 16′. This requires the veneer to be staggered and hot-pressed. It is very costly to use veneer, oftentimes we use wood staves to build larger doors.

For a tighter budget, we recommend using a paper backed veneer which only requires being cold-pressed. Sing Core provides the smoothest MDF skin for our clients to hot-press. Cross banding is not required with our smooth and high precision substrate, which may be hard to believe for some people. We have been doing this for many years with our innovative technology. We always recommend that our clients purchase our veneer substrate, complete with the same warp-free guarantee, and hire your local veneer contractor or do it yourself to save some money. One advantage to using a wood veneer as the skin for your door panel is that veneer can be easily matched to the surrounding area. One disadvantage to using wood veneer skin is that it is not well suited for exterior purposes, such as entrance door, and it can be difficult to repair if damaged. Veneer skins are the also limited to the maximum door size of 10′ by 16′.

Large Interior Doors

Masters of oversized doors, Sing Core has been enabling the biggest door manufacturers in the USA to make the best biggest doors that can be made and guaranteed to remain warp-free for 50 years. For 50 years, the major door companies opted out of the large interior door marketplace because the rate of complaint and return was too high, easily eating up year-end profits.

So, the door companies would supply all the standard-sized door while referring the large exterior doors, large pocket door, large interior doors, large glass sliding doors, large garage doors or large wooden doors to a millwork who specializes in one-off specialty doors and let them deal with the service calls.

Then, about 20 years ago the millworks started making doors with Peter Sing’s patented Sing Core inside. Now they could make huge exterior doors and large interior doors, including large wooden doors that would stay straight and true for 50 years, guaranteed. Until the invention of Sing’s core, this was never possible in the large interior door industry.

It took a few years for the standard door manufacturers to come around, but they did. Now you can do to just about any door company and get the entire door schedule for any project including the huge mammoth-sized doors all sourced from one company, plus the entire package could be covered by the manufacturer’s warranty without having to have a rider to exclude the big interior doors or enormous exterior doors.

Sing supplies the warp-free door blanks for each door company’s designer oversized doors which are available in any custom size large doors up to 50 ft. Sing’s interior doors come in a wide variety of styles to accommodate any size or style, allowing architects and designers to freely express themselves in terms of door sizes with unlimited large interior door options.

Floor to ceiling doors are reaching new heights of interior door designs for everything from custom interior to wine cellar doors in contemporary architecture and design projects across the USA. These large luxury interior and exterior doors are available in any flat building material such as wood, steel, and fiberglass exterior, and interior doors, including storm, and patio doors.

 

No job is too challenging for patented Sing Core. Sing has a specialized True Flat Team which reviews every job that would otherwise be too challenging to consider for any conscious project manager. The team reviews all the data of the fashioned interior door designs and comes up with the best solution(s) to provide a door that is

Lightweight (a fraction of the weight of other solid core doors)

High strength (Sing Core is rated at 600+ PSI, stronger than steel lb. for lb.)

Fully insulated (for sound deadening and climate control)

High precision (Sing’s core +/- .006 in. tolerance)

Warp-free (guaranteed for 50 years)

As many of Sing’s clientele has admitted,

“There is just no other way to do it.”

Sing’s Core doesn’t have too much advantage for use in standard sized doors, though companies who specialize in impact doors, sound proof doors, and high end refrigeration applications do build smaller doors with Sing Core inside.

Where Sing’s core really shines is in doors that start at 48″ x 96″(4′-0″ x 8′-0″) doors and go up from there (to 50 feet?). You probably want to know,

How to buy the best large interior doors for your home

It is easy if you have an architect onboard, your architect simply specifies a door with “Sing Core inside” then the rest of your team just makes it happen. If not, you can contact any of your favorite local door companies or millwork (just Google “millwork near me”) and tell them what you want. Peter Sing and his True Flat Team will use all their resources, patented and patent pending, to create for you the warp-free large interior doors of your dreams.

How can Sing deliver such large doors?

Military and government agencies are able to coordinate transfer of items that are too large for average transport, otherwise Sing designs them as modular big interior doors that can be assembled onsite, with all the precision of being assembled in his factory. This is another piece of the puzzle that Sing has mastered.

So, whether you are looking for the highest quality exterior doors or the widest range of interior door styles then and you desire only the best doors ever made with the best warranty in the United States, then made in the USA premium doors with Sing Core inside are the only doors that will do.

Accept no substitutes. (Don’t get caught trying to switch a regular door with one that has been specified as having Sing Core inside, because when it fails, the customer will contact Peter Sing, and everyone will know that you tried to cut corners… true story.)

Everything from impact resistant slab doors to premium and unique interior doors because every door with Sing Core inside is an individual work of art, which is guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years.

Make sure your handcrafted beautiful custom wood doors and beautiful solid wood interior and exterior doors have Sing Core inside.

Only inventor Peter Sing’s warp-free veneer substrate can keep your veneers and laminations from warping over time. This is especially important in free-standing applications, such as temporary walls, display walls, and large doors of any size.

When your veneers or laminations are applied to any flat surface, like a wall or a floor, you have nothing to worry about when it comes to unexpected movement, but these free-standing applications are always a problem when trying to keep your product straight.

The application for which Sing Core is unsurpassed in superior performance is that of large doors. Door companies that long ago refused to make large doors due to the liability of warping not long after installation, are now making the biggest doors available to their custom clientele. That’s why architects spec Sing Core inside.

50-year Warp-free Guarantee

Only large doors with Sing’s patented Sing Core inside can be guaranteed not to warp, bend, twist, or otherwise fail for 50 years, including structure.

 

We Do Not Build Doors

We only provide the best millworks and door companies with the warp-free doors substrate. Our customers are the one’s who have our door cores finished, veneered, or laminated. We only provide the substrate. Our clients are the ones that make the doors look so amazing.

We Need You and Your Services

When an architect or contractor in your area specifies “Sing Core inside” whatever job is at hand, we do not do the veneer or laminate. We send our work to you.

We are constantly on the lookout for new laminators and veneer shops to add these materials to our core for the architects and contractors who have spec’d our material.

High-end Veneer Doors

Sing Core specializes in increasing the performance, durability, and customer satisfaction in high-end veneer work in custom veneer doors of any size which can be guaranteed to remain warp-free for 50 years, including full structure warranty. No other method of manufacturing a large high-performance veneer door can achieve these results.

It all starts deep within the structure of any veneer door with Sing Core inside. Sing Core is the patented brainchild of inventor Peter Sing who conceived of the structure core which revolutionized the way doors were made.

 

The biggest and best door companies, millworks, and custom door manufacturers love it, and you will find them using Sing Core inside all their high-end custom large veneer doors. And that’s why you’ll find them at the top of the tallest building in the United States of America, World Trade Center 1‘s Freedom Tower.

Telegraphing and Crossbanding

The most environmentally conscious way to create a veneer door is with a thin veneer material, such as 0.020-inch veneer. The only problem with this thin veneer is telegraphing.

It is normal to crossband veneer, which basically doubles the price of the veneer, to prevent telegraphing.

Not necessary with Sing’s super-smooth veneer door blanks. He uses his patented veneer door technology to create an extremely smooth surface to lay veneer on flawlessly by using a thin later of MDF to accommodate the lamination of a thin veneer.

Problem solved.

Large Oversized Veneer Doors

When architects spec an architectural veneer door, if it is a very large door (anything over 8 ft tall or 4 ft wide) they are far better off going with a thin wood stave surface. Wood stave consists of wood planks cut into thicknesses of 1/8 to 1/4 -inch thickness. Then this solid wood is applied to Sing’s door blanks.

Veneer is normally limited in available lengths, whereas planks of specific wood species are generally available in longer lengths. This can accommodate the long length necessary for a vertical grain veneer door design.

Plus, if it’s done right, your high-precision large wood stave door with Sing’s core inside looks just like a solid wood door. Only it weighs far less than any other solid core door, and can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years.

And no other door can come backed with such an impressive guarantee.

Even though Sing’s doors are desired by nearly everyone, to have such a door may be cost-prohibitive for most. It is more common to find high-end veneer doors with Sing Core inside in the most expensive homes in the USA. You may find them used in scientific research, and anywhere in the world, from beneath the sea (US Navy) to outer space (NASA) and anywhere in between.

Sliding Interior Doors

Interior sliding doors have come a long way, and now you have so many choices available in the most modern sliding door ideas that anyone could have the most stunning side-sliding entry point. From the sliding barn door to the sliding pocket doors, these space-saving sliding interior doors are among the best sliding doors in the world.

The best exterior and interior sliding doors made in the United States of America all have patented Sing Core inside and are guaranteed to remain warp-free for 50 years, including a full structure warranty, and this is not to be found in any other interior sliding doors.

Sliding interior doors may not sound like a complicated job when it comes to including architectural details or incorporating large sliding doors in your designs, but if you’ve had your feet in the clay for some time, you should be aware of the problems which may be presented by internal sliding doors, especially if they are large in size.

First off, the most desirable material for sliding interior doors is any number of natural wood species. Wood sliding interior doors can be a challenge, if not at the outset, then definitely over time. Why? Because wood moves. It may no longer be a part of a tree, but it still responds to changes in the environment, which causes your sliding interior doors to warp.

Thanks to inventor Peter Sing and his inventions at Sing Core, door manufacturers (some of the largest and most prestigious door companies in the world) can create warp-free indoor sliding doors that can be guaranteed to remain straight and true for 50 years.

How to Make Warp-free Sliding Interior Doors

Sing’s patented and patent-pending warp-free wooden door technologies are based on a basic well-known wood crafting technique called torsion box, which is a respected technique for building things out of wood that will resist warping as well as reducing the overall weight of large wooden items such as conference tables and internal wooden sliding doors.

Though Sing’s invention does stop there, his warp-free-door technology goes so much further beyond standard wood working techniques. For instance, he started out by reorienting the direction of the torsion box frame from horizontal to vertical. That, in itself, was a huge improvement for warp resistance and increasing shear strength. But he didn’t stop there, either.

 

Next, he filled all the individual rectangles (hollow spaces left open in traditional torsion box designs) with rigid foam and secured these metric components between two stress skins using formaldehyde-free glue in the most Eco-friendly manner for the most sustainable substrate known for use in sliding interior doors.

 

Sing unveiled his truly modern barn door, and the biggest and best door companies, were all over it. Prior to Sing’s invention, the big door companies had all but eliminated the production of oversized doors of any kind due to their propensity to warp, making them impossible to warranty, and repeated service calls made them impractical to offer. If they did take on one or two large sliding interior doors, they would add a rider to the contract indemnifying them from any responsibility due to warp.

Keep in mind that even though the best sliding interior doors have Sing’s core inside, his company does not actually build doors, even though Sing is well known for making some of the most perfect doors, he only supplies the raw product, the door blanks or sliding door core, to the door companies, millworks, and high end custom door manufacturers, who actually create the masterpieces on his canvases for which he is so well known.

They are in the process of expanding their large custom sliding interior door divisions because they can confidently deliver a high precision, high-end solution which includes Sing’s 50 year structure and non-warping guarantees.

So, now you can get large sliding interior doors that are lightweight, insulated, stronger than steel, and made in the USA that are guaranteed not to warp for 50 years. All you must do is to contact your local door provider, and tell them you want, “Sing Core inside.”

Double French Doors Exterior

Exterior French doors are all the rage because if they’re done right, they offer superb safety and security while being Eco-friendly, lightweight, and fully insulated for increased sound deadening and climate control. The only way to create a sustainable lightweight pair of large double front doors that possess these double French doors exterior characteristics, which are also stronger than steel and guaranteed not to warp for 50 years, is with Sing Core inside.

 

Why is Sing Core so important for the most particular door afficionados in the world?

Granted doors with Sing Core inside may not be necessary for the masses, as standard doors available in standard door sizes are less expensive and adequate for normal everyday use. “Normal” doors move. The AWI standard for a normal 3-0 7-0 door is one-quarter-inch of movement, and the normal door industry from the door manufacturing companies, the hardware industry, and installation contractors all follow the guidelines of allowing a quarter-inch of movement without affecting normal door operation.

FRENCH DOORS

While you may think that glass is fairly stable, the frame which holds the glass (the French door) is subject to movement. It is the unforgiving glass which makes French doors more prone to failure, for if one corner is the slightest bit out of plum, the opposing diagonal corner will stick out like a sore thumb.

 

DOUBLE DOORS

Multiply the potential for failure times two, if you have two times the doors. A double door, two doors side by side, can potentially have uncooperative movement, even in normal-sized doors of 7 ft heights, double doors can have up to one-half inch of potential movement and still not be considered officially as warped doors, yet this exceeds the efficacy of the hardware, rendering the double doors inoperable.

EXTERIOR DOORS

To further complicate the problem with door movement over the life of a door which is more likely to move more often according to changes in the environment, and even more so, if one side of the door faces the structures interior and the other is exposed to the elements. This is the recipe for the perfect door disaster. That is why interior doors cannot be used as exterior doors. Exterior doors need to be made to different specifications to maintain the same “normal” quarter-inch movement allowed.

 

DOUBLE FRENCH DOORS EXTERIOR

As you may have guessed, by putting all these elements together in one set of doors, you have the makings of the greatest numbers of challenges associated with a single point of entry. Incredibly special attention should be in place when considering double French doors in an exterior front door application.

DOOR MATERIALS

While French doors may look like there is little at risk of compromising your egress point, there is much to take into consideration as each of the materials used in the construction of your exterior French doors has its own unique set of challenges as in integrates with the glass and its response to changes in environmental surroundings.

BIG DOOR PROBLEMS

The biggest problem with the door industry is with size. Normal movement of a door may be tolerable in a door that is 7 ft tall but once the door exceeds the 7 ft height, the rate of movement increases exponentially. The biggest problem with bigger doors is this increased movement which is referred to as door warp.

THE BIGGEST DOOR SOLUTION

Solving the problems associated with double French doors exterior is not a one-size-fits-all solution. Inventor Peter Sing’s patented and patent-pending door technologies are changing the way door are made around the world, and his True Flat Team is prepared to take on any unique and challenging combination of sizes, styles, and materials.

WHO TRUSTS THE SING SOLUTION?

The largest door companies in America trust Sing Core with their modern double front door solutions to provide their customers with the best in high-end double French doors exterior or interior, especially if they are very large in size, and they are backed by the best guarantee in the door industry: 50-years of flawless service.

 

50-YEAR GUARANTEE

Double front doors made with Sing Core inside can be guaranteed not to warp, bend, twist, or otherwise fail for 50 years, including full structure warranty and guaranteed not to delaminate. 50 years! No other door company can do that.

SUSTAINABILITY

No other lightweight Eco-friendly exterior double door promises flawless longevity like Sing Core, and while it is lighter in weight than other solid core doors, Sing’s patented core is high precision (+/- .0006-in. tolerance) and stronger than steel pound for pound.

Extra Wide Front Door

The inventor of patented Sing Core invites anyone to challenge his claim to fame being,

“The only way to build an extra wide front door that does not warp.”

Peter Sing’s revolutionary lightweight high strength extra wide front door core is what makes it possible for all the biggest and best door companies in the world, millworks, and specialty custom architectural door builders to build extra wide front doors that can be guaranteed not to warp for 50 years.

What?

Peter Sing, the inventor of patented Sing Core and many patent pending anti-warp and composite technologies associated with the creation of extremely large door blanks (up to 50 ft. or more) which are high tolerance (within +/- .006 in.) and dead flat.

 

Sing’s True Flat Team reviews every extra wide front door spec and assists in the engineering of a door blank that can stay straight and true for 50 years.

Finally, thanks to Sing’s door building technologies, the biggest and best door companies, millworks, and custom door manufacturers are able to build enormous extra wide doors of nearly any material, which would otherwise be highly problematic to use, like solid wood for example, that are Eco-friendly and will not warp.

For some people, a door that is 42 inches wide or 60 x 80 front doors are considered as extra wide front doors, but here at Sing Core, our wide entry doors start at 48-inches and go up to 600-inches or more, so handling your wide front door is not going to be a problem for Sing Core.

How to Build an Extra Wide Front Door

You start with Sing’s patented hybrid torsion box composite wide door core, which is made of natural vertical grain wood fiber metric structure grids filled wall to wall with rigid foam sandwiched between two structure skins to complete the torsion box.

This creates an impervious warp-free surface to which you may apply nearly any flat building material to your specs to create any result you care to achieve.

All the biggest and best door companies, millworks, and large custom door manufacturers know this is the,

Only the best extra wide contemporary front doors are made with Sing Core, and yours should be too, especially if it is an extra wide contemporary front door, to make sure you don’t get stuck having to repeatedly fix your door over time, saving you the headaches and costly maintenance costs.

“There is just no other way to do it.”

To make a large door lightweight, so strong, that is fully insulated for sound deadening and climate control, and be guaranteed not to warp for 50 years, is inconceivable by any other known method besides using Sing’s unique inventions, science, and technology.

Until now, traditional solid core wood doors were destined to be heavy, especially if large in size, and most likely to fail not long after installation. Wood solid core doors in particular because, well, wood’s natural inclination, being a natural product that moves in response to changes in the environment in which it resides.

That’s why it is standard practice for door companies to exclude large oversized doors from the standard warranty which covers the rest of the door schedule. Large solid core wood doors are generally included on a waiver which exonerates the designers, creators, contractors, installers, and anyone else associated with those big, heavy doors from any responsibility for the door’s performance whatsoever.

Because until now, there was no way to make commercial grade solid core wood doors that had such high performance. For instance, a solid core wood slab door with Sing Core inside,

Moisture content is the main enemy for any large solid core MDF door slab, so proceed with caution when approaching the integration of any MDF door where moisture may be present. Areas to be avoided include bathrooms, laundry rooms, and kitchens, and MDF is not recommended for use as exterior doors.

In terms of high precision, Sing’s unfinished solid core door are straight and consisted with .006-inch tolerance and 660 PSI for strength. Its statistical data, like this, which makes Sing’s solid door core break the boundaries set by traditional building methods.
