Wood Veneers
Veneer allows us to create a high end finish with less weight and cost while offering a wide assortment of beautiful door surfaces. There are a number of different types of veneers that all provide excellent options that will compliment the styles of your structures. Difference species generally demand a different price. Some popular examples are Maple, White Oak, Mahogany, Cherry, Alder, and Hemlock. Veneers are sold in bundles and range in price, but generally use the most flawless wood to provide the absolute most appealing visual aspects for your doors. Standard veneer thickness is .020″, and is often used to decorate high end furniture, cabinetry, cabinetry, floors, and even plywood. You can trust Sing Core to veneer your doors, alternatively you can get substrate only and have your veneer applied locally.*
The beauty of veneer is the high quality wood grain appearance that provides you with the most natural aesthetics. Each piece is completely unique, because it is cut from the actual logs. Not only does this allow you an amazing modern appearance, but also you can achieve a more vintage, timeless, or antique look. Normally, better quality veneers are used for doors, because customers want the best looking doors they can possibly get. Door grade veneer comes in a few distinct grades.

Face Cut Options
Rotary Cut Veneer – Created by spinning the log and peeling off sheets, almost like unrolling a roll of toilet paper, rotary cut veneer is the most common type of veneer. The advantage of this type of veneer is that it results in one continuous sheet. It is a very cost effective way of producing veneer, but it results in a very unpredictable grain pattern.
Plain Sliced or Flat Cut Veneer – This is the second most common cut. In this method, thin layers are sliced one at a time along the width of the log. The slices, which are also called leaves, because the blade works its way from the top of the log to the bottom, there is a gradual transition in the grain pattern. This method of cutting parallel to the growth rings results in a V-shaped pattern that is often seen on sheets of plywood.
Sapele and Oak Stave Combo
Rift Cut Veneer – Another interesting method is the rift cut process, which allows for a more straight-grained look. In this method the log is quartered, then cut perpendicular to the grain in repeating arches. The advantage to this is that you get a relatively uniform grain appearance. The disadvantage to rift sawn veneer is that it costs more, because the process is more time consuming.
Quarter Sliced Veneer – This type of veneer is also sometimes called quarter cut or quarter sawn veneer. This cut is often specified when the customer wants an exceptionally straight grain appearance. First, the log is quartered, which allows each quarter to be sliced perpendicular to the growth rings. Since leaves are cut more narrowly than plain sliced, they are much more easily lined up with other leaves, allowing for superior uniformity. Despite it’s vast advantages, this method requires a larger log diameter compared to the alternative methods. This method also achieves a sort of flaking appearance, created when the veneer knife bisects medullary rays in the tree.

Veneer Matching Options
No matter what cut of veneer is applied, without proper veneer matching, your project will not turn out as expected. Veneer matching is a true art form. The job of matching veneer is a precise job that requires a detailed approach. The appearance is partially determined by how the veneer slices are lined up on the doors.
Book Match Veneer – Every other veneer leaf is turned over, like the pages of a book. With this method, the veneer will be mirrored between each consecutive two leaf section, resulting in a repeating series of symmetrical patterns. This method is preferred by many, because of the continuity of grain. This method produces both ascending and descending prominent characteristics of the grain. Not all cuts of veneer can be used with the Book Matching method, however, but plain, quarter, or rift sliced veneers can all be used for this purpose. This book end formation tends to reflect light and accept stains differently. With this method there is also potential for wide color variation, known as “barber pole” in some species or flitches. Despite these variations, they are still considered desirable.
Random Match Veneer – This method produces a more chaotic appearance, because pieces are generally unmatched, as if the applicator has taken a series of boards and lined them up on the surface of the door. This produces a more old fashioned look, as something that was perhaps built before modern methods of veneer were invented. With this method, there is often a deliberate method to reduce grain consistency.
Continuous Match Veneer – This is when the pieces of veneer are used for both the door and the transom, allowing for a very consistent look between the door and the transom.
End Match Veneer – This is generally selected for doors with transoms. This match uses a single piece of veneer that runs from the bottom to the top of the door. Veneer can be turned turned at the joint to achieve this appearance.
Slip Match Veneer – This is one of the quickest methods of matching veneer, but requires higher quality veneer that is fairly uniform in appearance. Sheets are slipped out on the the surface one after the other, creating a wave of repeating patterns. Some frown on this method, because of the abrupt joints. This differs from book match veneer in that book match is better at hiding the joints. Uniformity of color is superior in this method, because each piece has a similar level of light refraction. It also allows for a relatively straight grain pattern.
Blueprint Veneer – is sequential veneer from a single source to cover an entire area. Complete rooms are the most impressive when they are blueprint veneered. Some jobs include matching blueprint door skins as well. Proceed with caution, making sure there is enough source material to complete the job, and there is no room for mistakes.
Natural Variations
Because wood is an organic product, each piece has its own characteristics. There is a vast array of grain patterns and formations, which can vary among trees and different flitches. Because of that, some trees may not meet standards. Other trees may considered of exceptional quality. Prices may also vary depending on the quality and appearance of the veneer. Because of variations in natural grain of each tree and differences in cuts, you can experience amazingly unique grain, pattern, and color, for each leaf of veneer, which translates into an an unlimited variations in door appearances.
In all cases, the natural wood quality will improve and compliment design elements, especially if the wood is applied in its natural state, unfettered by paints and enamels which might hinder the actual beauty of the wood.
Some species, like maple and birch can show a wide variety of color ranges. When it comes to maple and birch unlimited amounts of sapwood and heartwood, large portions may be unusable, because of unacceptable color. Sapwood lighter in color, while heartwood is darker in color. There is also the issue with light, dark, and color streaks, spots, and color variation that results from mixing sapwood with heartwood. If these sorts of variants in color and grain are not desired by you or your customers, veneer must be selected accordingly. If lighter shades of veneer are desired, you must specify sapwood maple or birch. If darker shades are required, you should select heartwood, however, this type is often limited in supply.
* = Professional veneering can be very tricky. If you are getting substrate from Sing Core and having your millwork (or someone else) apply the veneer, be certain to affirm that they have the expertise to apply the veneer appropriately. We use the highest level of professional veneer professional and techniques. We can guarantee our veneering, if you have veneering done off-site, it is their responsibility to do it correctly. A faulty veneer could jeopardize your Sing warranty.
Door Graphics and Murals
Our doors make an exceptional surface for applying murals, canvases, or printed wraps and images. This is an excellent way to make an otherwise standard looking door, beautiful and vibrant.
In recent years, graphics, scenes, or photos applied to the surfaces of doors that turn your openings into true works of art. This style of door is only limited by your imagination! Some examples are as follows:
Fine Art: Amazing portraits, scenery and landscapes, animals, objects like cars and still life images
Designs: Patterns, colors, shapes, and other abstract art
Wood Grains: Any sort of wood species, style, or colors
Plants: Beautiful flowers, leaves, barks, and other plant based imagery
Textures: Pebbled, rusted, grainy, smooth, baked earth and other textures
Other: Anything you can imagine can be printed Sing Core doors as long as you have high quality electronic images and graphic files.
We start with a smooth tempered board or Medium Density Overlay (MDO) for a best quality finish, or select a wood veneer or paint grade option for your highest quality finishes. This is only limited by your imagination!
Pocket doors have become an integral part of modern architectural design. Despite the many advantages of pocket doors, they do present unique challenges in both the manufacturing and the installation process.

About Pocket Doors
Pocket doors are desirable as they are invisible in the opened position as the pocket sliding doors are hidden away in cavities within the walls in one, or two opposing, wall(s). Pocket doors serve as a retractable room divider, functioning as an elegant and effective method to separate one large space or two adjoining spaces, while the sliding door divider(s) disappear(s) into the wall.
Proceed with caution, as pocket doors can be hugely problematic if they move according to changes in the surrounding environment. A warped pocket door will damage the finish as it rubs against neighboring surfaces and if it bends or cups too much can get lodged inside the wall, and the bigger the pocket door, the greater likelihood of warping.
There are many reasons to have your pocket doors made with Sing Core but the number 1 reason is to stop worrying about warped pocket doors once and for all by specifying
Sing Core Inside Your Pocket Door
Thanks to inventor Peter Sing’s patented and patent-pending large pocket door technologies, you can have an Eco-friendly pocket door that is lightweight, high strength, fully insulated for sound deadening and climate control, covered by Sing’s
50 Year Warp-free and Structure Guarantee
There is no other way to build a high precision (Sing Core tolerance is +/- .006 in.) sustainable pocket door that can remain straight and true, spanning the test of time.
The Best Pocket Doors
Sing Core has become known for making some of the largest, most impressive sliding doors on the market. Pocket doors are sliding doors that slide into a pocket in the wall. Certain customers have come to know Sing Core, not only for our sliding doors, but also for our magnificent pocket doors. Introducing the best pocket doors!
Pocket Door Challenges
The concept of pocket doors seems simple very simple. They are similar to sliding doors in that they slide on tracks and typically use rollers to open and close. The big difference is that they slide into a pocket that has fixed dimensions inside the wall. If the door warps or skews, the door cease to function. You will not be able to open or close the door because warping will change the dimensions of the door.
Warp Free Pocket Door
Over decades, we have developed our patented and patent pending materials that allow for super strong, light weight, warp free door construction. Warping and skewing present significant problems for pocket doors, because pocket doors must slide into a fixed space inside the wall. Any deviation from specifications will prevent the door from fitting into the space. When this happens, your door will cease to function. You will need to buy a new door, change out your hardware that may bend or break as a result of door malfunction. In some cases, you also need to rebuild your door frame or your walls when they are ruined from doors being opened and closed.
But we have solved all of the problems associated with large pocket doors and large sliding doors. When you use Sing Core products, you not only get a door that exceeds AWI standards in terms of warpage, you also get a door that’s guaranteed against warping for 50 years. Because of our special design methods, you will get a door that ensures proper functionality for decades.
Large Pocket Doors
The larger the door the bigger the challenge. Large pocket doors are more susceptible to warping. In order to function properly, they must be specially designed to resist warping. Larger doors must be specially constructed so that they are warp free on installation, as well as, over time.
Ultra High Strength – A large pocket door must be exceptionally strong to stand up to the most rigorous use. At Sing Core, we have revolutionized door strength with Peter Sing’s patented and patent pending technology that allows us to build doors that are very high strength, tested independently at over 660 PSI.
Super Light Weight – Up to 90% lighter than solid wood doors. Sing Core’s specially engineered core uses Peter Sing’s revolutionary design to bring a solid door strength to doors that allows for super light weight performance.
Straight/Warp Free – Specially designed stiffeners built into our doors make sure your doors are warp free over the long haul for better performance and function.
Structurally Stable – With our groundbreaking process, we can make doors that are built exactly to your specifications, and will not skew or shift over time. That way, you have a door that functions worry free for decades.
Eco-friendly – We support sustainability by using renewable, eco-friendly materials, so our products are better on the environment.
Guaranteed – When it comes to guarantees, no company on the market can do better. Our Sing Core Professional Panels are used for doors and other high end applications where stability and precision are of the utmost importance. All of our Sing Core Professional panels come with a whopping 50 Year Guarantee against warping, cracking, breaking, and skewing. Name one other company who can do this. Most companies don’t even offer a one year guarantee, but we can do this because our products have such a strong track record of performance.
No one can make panels as large, yet warp free like we can! You have our guarantee on that.
All of our products are 100% made in the USA. We take pride in supporting our country. That’s why you won’t find any products that aren’t made in America here. We also use high quality inputs that are sourced from local suppliers.
Door Skins
Our door system allows you to specify almost any skin for your doors. We specialize in high quality wood and metal doors. We have several options depending on your budget. Our paint grade ply option is our most economical option. Next is our hardwood veneer option. Mahogany, oak, walnut, and alder are popular. We also use 1/8″ wood stave on our highest end option, which gives you a solid wood appearance, but has our specially engineered core to maintain the light weight feature our doors are famous for. We also make metal doors. In our metal doors category, we specialize in cold rolled steel, but we also have a very popular aluminum option.

Customer Review: Joe Ballweg
⭐️⭐️⭐️⭐️⭐️ (5/5)
*”I needed a large (10′ x 7′) pocket door fabricated for an art studio renovation that would not warp or be too heavy to maneuver. SingCore worked with the project’s budget to make their product practical. I appreciated the work Ivan did to ensure that the shop drawings were clear and met all the requirements for the installation.
Our door was shipped in 2 panels and I was given instructions regarding unpacking and joining the panels. Ivan was also helpful in offering advice on how to deal with receiving the 650 lb crate without a loading dock and with minimal help.
The process of joining the panels was involved and some preparation was required, but I asked many questions and they were all answered thoroughly and helped with the entire process. I wouldn’t hesitate to use SingCore again or recommend them to anyone needing a large stable panel.”*
— Joe Ballweg
Lightweight Yet Solid Modular Door System
First of all, Sing Core panels use our patented honeycomb core. This unique core is designed to be ultra-light while maintaining the solid feel of a traditional wood or metal door.
Even oversized doors become easy to move and install. In many cases, a single person can handle the door without special equipment. This reduces labor and makes every job easier.
In short, you get a door that feels solid without the weight that slows you down.
No Warping—Guaranteed for 50 Years
Warping ruins doors over time. It causes misalignment, poor sealing, and eventual failure. However, our Modular Door System completely solves that issue.
Each panel is guaranteed to remain warp-free for 50 years. That’s right—five decades of guaranteed performance. You can install massive pivot doors, custom sliders, or tall entry doors with full confidence.
Because the system is built to last, you won’t face costly callbacks or repairs.
Unlimited Sizes and Endless Options
Traditional doors are limited by material size and weight. In contrast, our modular design removes those limits. You can build doors as wide or tall as you need by connecting multiple panels.
Furthermore, the system works with almost any type of door: curved, pivot, sliding, or folding. This makes it ideal for unique designs and oversized architectural features.
Plus, every door is built to order. That means you choose the finish, edge banding, core options, and more. Whether you need fire-rated skins or soundproof cores, we’ve got you covered.
Easier to Ship and Faster to Install
Large doors often come with big problems during shipping. They require custom crating and oversized freight. Thankfully, the Modular Door System avoids all of that.
Instead, we ship each door in compact, lightweight panels. These smaller sections are easier to handle, store, and transport. This helps reduce freight costs and project delays.
Once on-site, the door panels connect using a concealed alignment system. The result is quick, accurate assembly that saves time—and eliminates frustration.
In Summary: Sing Core’s Modular Door System delivers strength, flexibility, and efficiency. It solves common problems faced by architects, builders, and contractors—while opening up new design possibilities.

One of a Kind Sing Doors
Keep in mind that no two doors with Sing Core inside are exactly the same (except in the case of large bulk door orders).
Every door with Sing Core inside features a uniquely engineered base door material which is manufactured to exacting standards taking into account all the details of the application associated with each door.
Attention to Detail
Attention to detail is the method of ensuring that each Sing Door can be guaranteed for flawless performance and longevity by taking into account where the door will reside when it is installed. What will the climate conditions be? Will it be installed inside, outdoors, or will it be a front door with one side exposed to the elements and the other to the structure’s interior?
Will your large exterior door be facing North, South, East, or West? What materials will be used on the exterior of the door? Will the surface material need to match other doors featured in the project?
Large over-sized wooden doors present their own set of challenges because every different species of wood grain has its own propensity to shift with changes environmental changes, like temperature and humidity. Sing Core inside as well as the stiffening and anti-warp configuration in the door substrate will have to be uniquely matched to any difference in door size.
Sing Core is not a one size fits all solution
That’s why you find Sing Doors featured inside the most expensive homes, commercial, and industrial locations in the United States and around the world.
It’s no easy job to make a warp-free large door, especially if it is door of enormous proportion which needs to remain dimensionally stable and warp-free over time, but as the most prestigious millworks and custom door manufacturers already know, Sing Core is the only way these results can be achieved.
Sing Core Solved the Problem

Under the supervision of Master Inventor, Sing Core Founder, Peter Sing, we got right to the task, designing this system for maximum performance and lighter weight. Using our patented and patent pending Professional Sing Panels. Sing Core is the best product on the market for these types of applications, because our core is stronger, tested independently in UW labs to be able to withstand 660 PSI of force, up to 90% lighter in weight than solid wood, more versatile, and more visually appealing than any other product on the market.
Because Mr. Abke required only a 1” thickness on his panels, he could not use just any material. He needed the strongest, lightest weight material he could possibly get ahold of. These panels had to be stronger than steel to endure the punishment he had planned for his Mercedes van conversion. This configuration required that the system be able to hold up several hundred pounds of weight without showing any signs of stress. These panels also offer much more insulation and sound blocking capabilities than solid wood or hollow core panels, thanks to Sing Core patented and patent pending technologies.
See how small these panels fold up! They are barely noticeable once folded for storage, and they are completely out of the way, thanks to James Abke’s implementation. This design allowed him to fold down the panels so he could use them as storage or else move them to the side and use the full space in the back of the van for cargo.No oneelse can do this.
Multi Purpose Design
James Abke was driving across the country in his van when he got the idea to do the unthinkable. Because of his unique need for a system that would allow him to work, sleep, as well as, store luggage in his van he designed a system that would be able to accommodate all three.
“I worked with several Singcore agents to find a solution and came up with a panel that I was able to coat with a truck bed liner (Rhino-Liner) in order to make the panels nonskid and very durable.”
-James Abke
The icing on the cake was that Mr. Abke’s design was able even able to accommodate a bed. Because of the ultra high strength, lightweight, warp free quality of Sing Core, James Abke was enabled to design a system that could easily accommodate two people, 500 pounds with no difficulty at all, without any compromise at all to the integrity the structure. Having a bed in his van allowed him to sleep on location, anywhere.
This was the perfect application for our products.
“It was imperative to me to have light weight panels strong enough to hold two people (for camping mode) or heavy equipment (in work mode) and be thin enough to be able to be stored inside a rather compact cargo van when they were not in use.”
-James Abke
James Abke’s design was simply one of the ways we can do this. The possibilities are only limited by your imagination. We can even make drawers or other additions that can give you better storage options than you ever imagined. For this sort of application that requires such precision, high strength, light weight, and warp free character. Sing Core is the only solution for this type of situation.
We do not make SIP panels. SIP panels will bend, break, twist, and crack. They are made very cheaply with Chinese materials. Our panels are made from the absolute best materials. They are made 100% in USA, using materials sourced from the USA.
James Abke’s new system can hold huge amounts of luggage. Sing Core technology allowed him to have more than one layer of storage in the back of his van. With our technology, we can manufacture panels that are stronger, more durable, lighter in weight, more warp resistant, available in more skins, with more bells and whistles. Moreover, they come in any size, larger than any other panels on the market, they are more visually appealing, and come with many more features. Not to mention, they are the only panels on the market that come with a full 50 Year Warp Free Guarantee. They are 100% made in America, using materials sourced from the united states.
