Guaranteed True Flat for 50 Years
Let there be no mistake, this is the only way to build an interior sliding door, closet sliding door, barn door, exterior slider door, or any other type of large wooden sliding doors which can have the best door guarantee in the world, thanks to inventor Peter Sing’s patented and patent pending warp-free core technology for 50-year guarantees for sliding wood doors.
Until the invention of Sing Core, wooden sliding doors and barn doors were notorious for presenting problems for architects, designers, engineers, custom door manufacturers, installers, and door maintenance contractors due to warping following installation.
Why Is My Wooden Sliding Door Warping?
Unfortunately, this is the nature of natural wood grain. Left to itself it will move as it adjusts to the environmental conditions which surround it. Especially frustrating, are sliding patio doors, and external wooden sliding doors which have one side of the door exposed one hundred percent to the weather.
This is a certain recipe for wooden sliding door disaster because a warped wooden sliding door can be potentially useless if it warps to the degree that it may not be easily slid back and forth, and in cases when such a sliding wooden door requires a degree of security, may not be able to be closed, latched, or locked.
That’s why contemporary architects and designers are increasingly specifying “Sing Core inside” their wooden sliding door designs as the premiere solution to for all your potential wooden sliding door problems.
Nobody intentionally specifies or installs barn doors, sliding closet doors, or sliding carriage doors with the intent of having them fail, require regular heavy maintenance, or sliding door repair. Pre-engineering your sliding doors with Sing Core inside ensures you have the best, most cost effective and sustainable sliding door system available in the world today.
Modern Sliding Patio Doors
The most comprehensive modern sliding patio doors with the highest precision featured in the most expensive homes, commercial, and industrial locations around the world are guaranteed to be warp-free for 50 years because they know there is no other way to manufacture such a sliding patio door.
Modern Sliding Barn Doors
Modern sliding barn doors are the most unique of all wooden sliding door designs as they are increasingly featured in modern interior designs and decorative treatments without compromising functionality or longevity.
Your wooden barn door can have all the benefits of having Sing Core inside your sliding barn doors by contacting your favorite door company, millwork, or custom door manufacturer who knows how to make a sliding barn door that can be guaranteed to remain warp-free for 50 years.
Now you, too, can have the best sliding wooden door system in the world.
Sing Core’s latest expansion following the acquisition of a new factory has resulted in a new line of affordable barn door and sliding closet doors at huge direct from the factory savings for you.
This new C Class division only produces quantities of sliding doors of specific size for retail markets. At present, these standard sized sliding doors are not available directly to the public because they ship in the same unfinished condition as all sliding doors which ship from the factory.
Sing Core only ships to high end custom sliding door builders, millworks, and sliding door companies who are qualified to finish and hang the completed lightweight sliding doors with Sing Core inside.
The advantage of our new, Class C Sliding Door Division is that they are tasked with only building a limited number of standard-sized sliding doors, while our Class S Division only builds custom sliding doors. Class C sliding doors are only available in MDF, which may have an unfinished wood look (like the white oak shown above) or standard paint grade. This results in a cost savings of more than 75% per door, and we pass those production savings on to you.

Insulated Walnut Door
Doors of Almost Any Style Could be Made with Sing Core Inside
1. Pivot Doors
Pivot doors are the highest and best use of Sing Core because for the most part, pivot doors are quite large in size and are often much thicker than a standard door. If your intention is to feature a real wood finish, you know you’re going to be in trouble, that’s when the warp-free attributes of patented Sing Core shines through as the only way to build a large wood door which can be guaranteed to offer warp-free performance over time: 50 years, guaranteed, on professional grade doors.
Pivot Door Room Dividers
2. Sliding Doors / Pocket Doors
Sliding Doors often present problems when they are very large due to their sensitivity and tendency to move, bend, or cup in response to changes in the environment, for which Sing Core is the perfect solution.
Large bypass sliding doors are likely to deface, scar, or otherwise damage themselves if they are not kept straight and true by being built with Sing Core inside in advance of bypass door failure.
Pocket doors, which are the most problematic of all sliding doors, because they hide within a cavity are highly benefited from being built with Sing Core inside. If warped, the finish of the door may be compromised as it brushes against the frame or cavity’s interior, and if it cups or bends too far, may become lodged either inside or outside of the pocket unable to open and close as a door. Sing Core keeps them straight and true.
3. Hinged Doors
Hinged doors are for the most part manageable even when facing a certain degree of warp, which is normal in normal sized doors. Problems arise when doors are very large, especially if over 7 ft. tall or 3.5 ft. wide. Any movement or change in the door’s being compromised is increased exponentially in relation to the dimensions of the door. Not a problem with Sing Core’s professional door blanks.
Diverse types of hinged doors, such as French doors, sliding folding doors, front entry doors, and carriage doors (among other types of hinged doors), all present varying challenges when migrating from the drawing board to the real world, and Sing Core makes the difference.
While Eco-friendly insulated Sing door blanks could be used in doors of any size, the efficacy is maximized in door performance in any door over 7 ft. tall and 3.5 ft. wide. This is why you find Sing Core inside the largest doors in high-end homes, businesses, and industrial sites, because it’s the only way to build a large door which can remain straight and true, regardless of the size of the door, while still remaining lightweight.
Since every door slab manufactured by Sing Core is likened unto a one-of-a-kind piece of art, architects and designers are free to create a door of any size and shape using any available flat building material.
Sing door slabs can be created to accommodate any shaped design in any thickness, and so it goes for any shaped light cutout for glass openings.
Wooden modern sliding doors
Sing door slabs are available in almost any skin you want, limited only by flatness (surface material must be flat), ability to be laminated, and availability.
Some examples include, paint grade plywood, aluminum, brass, cement board, cold rolled steel, concrete, diamond plate steel, fiberglass, FRP, galvanized steel, glass, hot rolled steel, LVL, Masonite, stainless steel, any wood species including exotic species, and many more.
Our most common specialty includes the cold pressing of solid wood stave to our patented and patent pending core material, resulting in natural wood doors that can be guaranteed to remain warp-free for 50 years. Unheard of in the wood working industries. We also supply high end millworks with hot-press-ready warp-free substrates to apply their skins to.
Accurate Panel Insure Tight Fit Bi Fold Doors
Available in any size and any shape, based on your drawing(s).
STC-rated Sound Doors
We assist in the creation of sound reducing or sound proof doors which can be STC-rated at our local world-renowned pro sound testing lab. Some typical composite configurations include combinations of steel, sheetrock, MDF, and other materials to achieve the sound proof results to meet your specifications.
Fire Proof Doors
We build fire proof doors to your specs and can have them rated at the fire-rating facilities selected by our fire proof door clients.
What’s the latest news in sliding doors in the door industry? Internal sliding doors with Sing Core inside are being specified by architects more and more in their sustainable housing and commercial designs. See our new C Series line of Affordable Barn Door and Sliding Closet Doors.
Long the solution for exterior sliding doors due to their Eco-friendly, long lasting solution for warp-free lightweight yet high strength as sliding doors which are exposed to weather conditions, sometimes, even the most severe weather conditions. For years, architects and designers have sought out the characteristics that only Sing Core can provide for high precision and superior performance over a long life of the architectural exterior sliding door.
As architects became more and more accustomed to specifying Sing Core in their door specs, they started to develop a taste for specifying large internal sliding doors also. Large internal sliding doors, especially if they are wooden sliding doors, are going to fail due to warp if they exceed a height of 7 ft. tall sliding doors.
Then as the trend to specify Sing Core in internal sliding doors continued to grow, something began to shift. In high end homes, commercial and industrial applications, architects were also specifying sing Core for standard sized internal sliding doors. As this trend continues, the question is,
Why Spec Sing Internal Sliding Doors?
That’s the question, right? And you might be surprised about the answer, because Sign Core is the obvious solution to exterior or large oversized sliding door which have the tendency to warp, bend, twist, or fail structurally not long after installation. It’s the only way to build a lightweight wood exterior sliding door exposed to the elements which can be guaranteed not to suffer from door warping for 50 years. So, that explains exterior sliding doors and large sliding doors, but regular-sized internal sliding doors?
Well, it turns out that inherit deep within the patented Sing Core composite sliding door core, which is a solid composite material made of vertical grain wood torsion box core which is fully insulated with rigid insulation inside. The result? A lightweight, super strong internal sliding door that is insulated and possesses the additional attributes of being able to control climate (an advantage of using Sign Core inside external sliding doors) and also imbuing the door with sound deadening qualities, a useful and highly sought after feature in upscale projects.
Sliding Door Hardware
Due to the lighter weight of the internal sliding doors, there is a great savings in terms of the sliding door hardware. Both in the cost of the hardware due to handling the lighter weight sliding door, but additionally in the installation of the hardware and maintenance over time, as the lightweight sliding internal doors cause less stress and strain on the hardware and structure with regular use over time.
One of the best uses of internal sliding doors with Sing Core inside is in the pocket door application. Pocket doors are the most important in terms of remaining straight and true because while a sliding door is far more forgiving, warped sliding pocket doors are become destructive to both the pocket door and the pocket which houses it, any further warping renders the sliding pocket door useless.
Pocket Door Hardware
Just as in the savings in sliding door hardware, pocket door hardware associated with sliding pocket doors featuring Sing Core inside is far less expensive to purchase at the outset and reduces the cost of pocket door installation, as well as requiring less long-term maintenance. Not that cost is always of the most importance in the most high end applications, but it means you can use those funds elsewhere in your project without affecting the overall budget.
Internal Sliding Door of Any Type
Whether architecturally specified at the beginning of the project, or as the most predominant use of internal sliding doors with Sing Core inside in replacement doors, your Sing architectural sliding doors are custom built to architectural specifications. They can be made of any available flat building material in any style of door. That is to say, all custom professional grade Sing sliding internal doors are one-of-a-kind warp-free pieces of art that can be guaranteed to remain warp-free (including full structure warranty) for 50 years.
50 Year Guaranteed Internal Sliding Doors
If you want the best sliding internal doors, then there is only one way to have slider doors of any size, type, style, made of any desired (and available) materials that have Sing Core inside imbuing them with the unique characteristics of being sustainable, Eco-friendly, built to last for centuries and can be guaranteed not to warp, bend, twist or otherwise fail for 50 years, guaranteed.
Wooden sliding doors are the most sought out sliding doors in the marketplace today. Increasingly, among contemporary architecture design the latest designs feature not only wooden sliding doors, but wooden sliding doors that are larger in size. Even though these large wooden sliding doors are highly sought after, the nature of the natural wood in wooden sliding doors does present some challenges.
Wooden Sliding Door Problems
Wood is Beautiful but Unstable
While we all appreciate the natural beauty of wood, the fact remains that this material comes from a living tree and naturally adorned with grain that is unique to each variety of tree giving it the elegant design feature of natural wood grain. The nature of the wood grain when we are so drawn to is also the most problematic feature when trying to create a sliding door which can remain straight enough to function properly. Natural wood grain, while it appears to be elegant in every way, moves as if the tree were still alive. In the sliding door industry sliding door manufacturers and those servicing sliding door accounts, there are specific words used to describe the conditions of wooden sliding doors when they fail, such as warp, bend, twist and cup.
Allowable Wooden Sliding Door Warp
Due to the nature of wood to warp, the AWI standard allowable warp for a door up to seven feet tall is a quarter of an inch of warp. ¼ inch warp in a 7 ft. door is considered a straight door. For wooden sliding doors over 7 ft. there is no limit to acceptable warp due to the nature of natural wood and its tendency to move subject to changes in the environmental conditions on either side of the door. The most problematic wooden sliding doors are exterior sliding doors because one side faces indoors, while the other side faces the elements. Interior doors have fewer problems with sliding door warp, but if they are over 7 ft. tall, will continue to present problems with sliding door warp.
Wooden Sliding Doors Are Heavy in Weight
The weight of natural wood is another issue to take into consideration when entertaining the idea of including a large wooden sliding door in your project’s design. Heavy wooden sliding doors will create added expenses very early on in the inclusion process, such as the added cost of shipping and handling. Moving the door from point A to point B will incur expenses based on the wooden sliding door’s weight. After the heavy sliding door arrives on the job site, installers must manhandle the door, and use heavy equipment to help maneuver the door on site. Additionally, a heavy wooden sliding door will require heavy duty sliding door hardware, which may cost many times more than the wooden sliding door itself.
Warp-free walnut wooden sliding door
Wooden Sliding Doors Have No Insulation
Large wood sliding doors vibrate, like a speaker, transferring sound from one side of the door to the other, which may not be a problem if your location is in the remote wilderness. Besides sound transfer, loss of energy is significant as wood is unable to maintain climate separation from one side of the door from the other, which is also many times more problematic for exterior sliding doors or doors separating two spaces that may have separate activities occurring on either side (such as office, meeting or recreational spaces).
Wooden Sliding Door Solutions
Warp Free Wooden Sliding Doors
The true flat team at Sing Core has a proven track record of providing warp-free sliding door solutions of any size (up to 50 ft.) based on its patented reinforced torsion box composite core and patent pending stiffener and straightening technology that enable them to make the only large sliding doors that can be guaranteed not to warp, bend twist or otherwise fail (including full structure warranty) for 50 years.

Lightweight Wooden Sliding Doors
Thanks to the Sing wooden sliding door solution, wooden sliding doors can be made lightweight without compromising strength. Hollow core doors are lightweight but are relatively useless and insecure but better than leaving the doorway empty. A lightweight door does not have to be weak, thanks to patented Sing technology that enables door manufactures to create a lightweight door that is stronger than any other known door core material, and weighs a fraction of the weight of any other solid core wood-based material.
Insulated Wooden Sliding Doors
The patented Sing Core wooden sliding door solution creates a one-of-a-kind sliding door that is as unique as your thumbprint. Every Sing wooden sliding door is an individual work of art, specially designed and built to meet or exceed architectural specifications, regardless of size or applications. One of the unique attributes of the patented Sing torsion box core is that it is pre-insulated. The empty spaced of the torsion box voids are insulated which imbues the wooden sliding door with characteristics of an insulated sliding door that offers climate control R-vale and well as sound dampening.

Patented Sing Core solid wood stave sliding door blanks feature the newest technology in the door industry for composite sliding doors yielding the only eco-friendly, lightweight, fully insulated, high-strength sliding doors with wood blanks of any size (up to 40 ft.) that can be guaranteed true flat and to stay flat for 50 years.
Large sliding door versus regular-size sliding door challenge (i.e., over 4 feet wide and over 8 feet in length):
Large sliding doors are heavy, dimensionally unstable, require more strength due to the heavy weight, and are a challenge to manufacture, ship and install. High-end jobs require precision and true flatness to please the customer. A homeowner’s architect, general contractor and mill worker must solve the problem of warped sliding doors. The solution to the challenge is to use patented professional Sing door blanks to make your sliding doors.
Sing Core wood stave door blanks help door manufacturers to create the only solid wood sliding doors that will not warp, bend, twist or cup following installation. This means no more continuous service calls for maintenance of big sliding doors that cannot possibly stay straight due to the limitations of solid wood – or any other sliding door core – that is subject to failure. Sing sliding door blanks have a patented honeycomb/torsion box interior which gives lightweight yet unsurpassed strength (pound-per-pound stronger than steel) and stability to any door, and allows Sing Core to provide a 50-year guarantee
Interior Wooden Sliding Doors:
Sing sliding door blanks make amazing designer doors in any style. With Sing sliding door core, fragile sliding doors such as French doors are made lightweight yet strong, not warping or breaking hinges, which will last for many decades.
Exterior Wooden Sliding Doors:
Sing sliding door blanks make sturdy exterior doors in any style. With Sing sliding door core, exterior sliding doors are lightweight and strong, even when oversized. Our professional wooden sliding doors are guaranteed to stay true flat and not warp or twist for 50 years
When is a door not a door? When it fails to function as a door.
The problem is that all sliding door core materials are either not high precision, too heavy or will move when exposed to moisture, humidity or change in temperature resulting in sliding door failure.
Heavy solid metal or steel will not warp, bend or twist, but is not high precision due to welding (sing core tolerance is + or – .006 inch!) and is often impractical due to the overweight issues causing excess strain on both the hardware and structure, causing continued maintenance issues. The solution is our patented lightweight yet strong Sing core wooden sliding door technology.
Finishing a wooden sliding door blank:
There are two types of finish for door blanks: paint grade and wood grain. Paint grade includes such finishes as domestic and marine plywood, etc. Wood grain finish includes such finish as solid wood stave and/or thin veneer.
Why Use Solid Wood Instead of Veneer?
Never settle for substandard veneer sliding doors again. Door engineers prefer to use inexpensive veneer as opposed to real solid wood facings because veneer is thought to be less likely to warp, bend or twist. But thanks to the super-strength of patented Sing Core technology, you can use solid wood stave and wood blanks with confidence knowing that your wooden sliding door can be guaranteed true flat and will stay flat.
How can a solid wood-faced sliding door stay true flat? As every woodworker knows, when using a solid wood surface, the grain will move according to moisture or temperature change causing the door to fail. When using our patented Sing Core as a substrate you can safely use solid wood because the patented solid torsion box composite material is continually keeping the wood grain straight and true. Whereas wood stave has more wood fiber giving it more of a chance to warp than thin veneer due to the unbalance of the both side of the door moisture contents, patented Sing technology solves this problem by combining patent pending stiffening materials throughout our Sing core. This warp-free Sing wooden sliding door technology eliminates the troublesome movement of the sliding door blank — warping is no longer a concern when wood stave is combined with reinforced patented Sing core.
Marine Grade Ply
In addition, solid wood is easy to work with, install (no need to hot press), repair and remodel. That’s why professionals trust Sing Core’s years of expertise in helping to design the only wood stave sliding doors (that look just like solid wood sliding doors) that can stay straight and true for many decades while respectfully honoring the beauty and elegance of solid wood, which far outlasts easily-damaged veneers, yet can be sanded and repaired if necessary.
Celebrate your real wood!
Our Eco-friendly lightweight, high strength alternative is the best solution for combating the issues associated with weight and size, especially large doors. Only our patented Sing torsion box/foam composite core combined with our years of experience provides guaranteed solutions for oversize sliding doors.
That’s why this technology is found everywhere, from beneath the sea (US Navy) to outer space (NASA) and everywhere in-between.
Sing sliding door blanks may be made using almost any wood species, like mahogany, redwood, teak wood, cherry wood, walnut wood, cedar wood, Ipe wood, sapele wood, poplar wood, ebony wood, ash wood, oak or any other hardwood or exotic wood types available.
This same wood sliding door blank composite technology is also a common solution for high-end projects like engineered hardwood flooring, shiplap, wood furniture, wood shelves, decking, shed doors or any other application demanding high precision and exemplary performance over time.
Domestic Wood Grain Plywood Sliding Doors
As an alternative to wood stave, domestic wood grain plywood could be used to create a nice wood grain surface, even for large sized wooden sliding door applications.

How is wood stave/veneer added to Sing panels?
Wood stave is added directly to the metal or wood skin of our patented Sing cores. Wood veneer may be added to an 1/8-inch mdf attached to the metal skin. Call us for a free consultation on the best option for your project.
If you’re looking for the best in large sliding door design, you’ve come to the right place. Sing Core specializes in creating the ultimate sliding door experience. That’s why you see Sing large sliding doors everywhere on planet earth and beyond, from beneath the sea (US Navy) to outer space (NASA) and everywhere in between.
The deal with sliding doors is that you want your sliding doors to remain straight and true throughout their service life. Architects, designers and end users face the issues associated with the problems associated with sliding doors, such as,
Problems with Sliding Doors
The first problem with sliding doors is that they tend to move (warp, bend, twist or cup) compromising the doors’ performance. Especially in the case of sliding doors because they hang parallel to a wall (like sliding barn doors), another door (such as double sliding doors) or within a wall (like sliding pocket doors). If the door does not stay straight, it can wreck either the sliding doors or the surfaces they slide against, or both.
Heavy Sliding Doors
One way to deal with the problem of warping sliding doors is to build them using extremely heavy and warp resistant materials, such as steel, which introduces whole new set of problems, which will increase maintenance costs over the life of the door. Even though the heavy sliding door may not warp, it will require expensive heavy duty hardware (which can cost many times the price of the door itself) which can easily be compromised due to regular use, as well as the added stress of using a heavy door, will add stress and strain to the frame and structure, also requiring additional maintenance over time. Some architects and designers might consider using a lighter weight metal, such as,
Aluminum Sliding Doors
Of course, aluminum sliding doors make more sense; though contemplating the use of solid aluminum sliding doors will still introduce the problem of heavy weight. One way to manage the weight of the door is to use a honeycomb material, such as aluminum honeycomb, paper honeycomb or some other type of honeycomb material inside the otherwise hollow core sliding door. The only problem with that is that as you introduce a lightweight substrate, the door begins to warp again, especially if they are exterior sliding doors.
Wooden Sliding Doors
Ah, the elegance and beauty of natural wood. We love it and exotic wood grains can instantly garner the awe and attention of anyone spying a large sliding door made of wood. This is why many large sliding doors are wooden sliding doors. As magnificent and appealing as they are, wood is the worst culprit of all, because it can barely sit still for as long as you can. Due to wood’s natural characteristics, it is most prone to warp, bending, twisting and cupping, because even separated from the tree, it still fights for survival and the grain will either expand or contract due to the elements it is presented with. Exterior doors are the most problematic because one side faces the interior space, while the other side faces the elements outside, a perfect recipe for door warp.
Large Sliding Doors
The bane of perplexed custom sliding door manufacturers is the additional challenges with doors which are taller than 7 ft. tall and wider than 3.5 ft. Very few, if any, custom door manufacturers or millworks will even consider guaranteeing a door over seven feet tall. Why? Because they know it is going to fail, and they will be called upon to deal with it. In most cases, the job as a whole will have a warranty on the work done, with the exception of the large sliding doors which are normally noted as exceptions to any warranty that might cover the rest of the job. That is, unless you know the answer to the problems associate with large sliding doors.

The high strength of Sing Core outperforms any other sliding door core material, independently tested to rate at least 660 PSI, which makes it stronger than steel pound for pound.
Other sliding door core materials do not create a high precision base due to product production inconsistencies or welding, while Sing Core is the most high precision at +/- .006 inch. Only perfect sliding doors manufactured with Sing Core inside can remain warp-free. Sing Core is fully insulated imbuing the best sliding doors with climate control (R rating) and sound deadening qualities (STC rating*) for greater safety and security.

Sing Core and More
Patented Sing Core enables architects and designers to let their creative genius run wild by incorporating Sing Core in all their projects, not just for large sliding doors as Sing Core is also available in panels, posts and beams to enhance the capabilities of any large scale project which may encounter problems associated with strength and weight.
* Note: STC rating varies according to size, thickness, skin, and other factors. Sing Core does not rate doors, although we are fortunate enough to have one of the best sound testing labs in the world, here in the Pacific Northwest. If you require a specific STC rating, Sing Core can build a door to your architectural specifications and have the resulting door tested at our rating facility for an official rating.
