Perfectly Straight, from Start to Finish
Many manufacturers shy away from larger sized doors, because of their propensity to warp. The larger the door, the more innovative the design must be to prevent doors from warping and skewing. If your doors warp or skew, they may cease to function as doors. Sliding doors, pivot doors, and pocket doors have an obligation to be extremely straight, because the hardware requires this to function properly.
That is why we build our panels to the absolute highest precision possible, within tolerances of +/- .006 inches. With our doors, you can rest assured that your openings will be functional for decades and decades to come.
Any Size Door

What Makes Sing Core Doors Different?
We have the best patented and patent-pending methods to create the largest, most lightweight, most insulated Eco-friendly most doors that can be guaranteed not to warp, bend, twist, or otherwise fail for 50 years. Sing Core uses the only door manufacturing methods which can deliver these extreme results in the largest, most high precision modern doors featuring any contemporary material, because conventional large wood grain doors are prone to warping and a host of other problems, including excess weight.
How Do You Build a Sing Door?
If you’re a custom door manufacturer, you start with a Sing Core door blank and build your large pivot door, large sliding door, large pocket door, or huge French door just like you would any other door that you build. Having Sing Core warp-free door substrate inside your door makes all the difference in the world.

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

“Sing Core inside your door.”

The Most Extreme Doors in the World by Sing Core
Many doors have made it into the Sing Core Hall of Fame, but today let’s focus on a few of the most impressive doors.
Tech Giant Huge Sliding Door
We were approached by one of the leading door and windows companies in the world, Cascade Door and Hardware to make this door that nobody deemed was even possible. With a span of 25 feet wide and a towering height of 9 feet tall, this door is, hands down, one of the largest doors in the world.
We were approached by a tech industry leader to accomplish a task known most often in the industry as “mission impossible.” We rose to the challenge, because we knew we could do it. This door is stronger, straighter, lighter in weight than any other door of its size in the world. Only Sing Core can do this!

In the door manufacturing industry. This kind of door is often called “mission impossible” and is selected by the most prestigious architects and designers in the world.
AIA Seattle Design Center Giant Pivot Doors
FAIA Mr. Peterson, a senior architect for Suyama Peterson Deguchi, called on Sing Core to make these huge pivot man doors for the AIA Seattle Design Center remodel. They needed doors that were extremely strong, yet light weight enough to work with their specialized door hardware. Their idea was to create a gallery that could be instantly converted into a conference area. Sing Core patented and patent pending technology made this possible by using our ultra light weight, high strength design.
Without Suyama Peterson Deguchi and Sing Core, AIA would not have been able to accomplish their tasks of converting their office space into a unique, convenient, practical, world-class conference room, gallery rife with style and elegance.
Terminal C-18 Film Screening Room, Minneapolis, Minnesota
The C-18 in Minneapolis, Minnesota Airport needed a double purpose wall, one side for their art exhibit, the other side for their quiet theater screen viewing room. The problem was that these walls needed to open and close to allow access the the foyer area.
Terminal C-18 knew there was only one company they could count on to get the job right. Sing Core rose to the occasion. The panels we manufactured and provided by far exceeded their expectations.
Sing Core has helped to create a better environment for everyone at Minneapolis Airport, because we can make our panels stronger, straighter, lighter, and more warp free than the competition.
Miller Blaker 16 Foot Tall Pivot
Miller Blaker came to us with one of the most challenging jobs in the entire world. They needed doors high quality enough to install on the top floor of the most prestigious building in the world. They came to Sing Core, because they knew our proven track records of building doors that are not only best in their class in terms of structural stability and strength, but also light weight enough to hang on Miller Blaker’s hardware of choice.
No one else can achieve the dimensional stability Sing Core can.
These doors had to be perfectly straight, dimensionally stable, and incredibly strong for use in such a challenging scenario. Miller Blaker required doors that were 16 feet tall, 3 feet wide, yet only 2.25 inches thick. Often these kinds of dimensions are what industry professionals call “mission impossible.” Here’s at Sing Core, we make the impossible possible.
Moreover, we built these doors with a solid oak edge that makes the entire door appear like solid wood with no seam. Only Sing Core can do this!
When Miller Blaker came to Sing Core, what we ended up with was a winning combination all around, one of the best architects in the world, paired with the best materials in the world, for doors that would end up in one of the best locations in the entire world.

One of the leading design firms in the country needed a very special door for one of their best customers. They needed a door that was not only strong, but also straight because of the sheer height of the door. This door measures a whopping 21 foot tall, making it one of the world’s tallest pivot doors ever made. Not only did this door need exceptional strength and warp free, but also, because of the magnificent size, it had to be extremely light in weight. What everyone else calls “mission impossible,” Sing Core calls a job well done.

The best metal doors in the industry have Sing Core inside them. We start with a super strong, super light, ultra straight panel, then encase it completely in metal, resulting in a metal door that is up to 900% lighter than solid metal doors, while maintaining increased structural strength, better resistance to warping, and a much higher degree of visual appeal.

Here at singcore, we make the impossible possible! Doing the impossible while providing you with exceptional quality products is part of our philosophy here at Sing Core.
When your beautiful new Sing Core door sections arrive, it is important to take the time to glue the door together properly. Although Sing Core panels are guaranteed warp-free, we cannot guarantee work done on site. Failure to properly follow these directions may result in a poor final product.
Sing Splines Don’t Crack
Sing Core uses our patented core material as a spine to join several panels on site. Unlike solid wood, the stability of the core material means that there is no danger of cracking or splitting of the seam at the join location.
Join on Site in Three Steps
1. Lay Your Door Panels Flat
It is crucial that all of your panels are resting on a flat surface and are completely level. If you attempt to glue the panels together against a wall, or any way other than flat, you will end up with a crooked joint and a “warped” door.
The first step to join a Sing Core sectional door is to lay the panels on a flat surface. Any flat clean surface will work. For very large doors we like to use two straight beams laid on the ground along to hold the top and bottom of each door segment.
2. Insert Your Biscuits or Spline into the Edge of One Panel
Each biscuit and slot are precisely cut to join with the greatest strength. Carefully, push or hammer each biscuit lightly in place into the edge of one panel. Then your panels are ready for joining.
3. Joining the Panels
The final step in joining a modern sliding or pivot door is to press the sides together. This can be accomplished a variety of ways, including gentle application of a sledge hammer, a few ratchet straps, clamps, or any other means you have of providing joining force. Once joined, the door is strong and secure, built to last, and can be finished and installed as any other Sing Core door.

Joining in Action
How to Clamp at the Join
When you want perfect alignment for very high tolerance applications, it’s best to sandwich each joint with a straight guide temporarily during the gluing process.
In order to make your process easier, Sing Core offers construct custom true straight guides for your application and ship them with your order. These guides are made with the same high precision core material as our other products and offer superior ease and performance.
Specify you would like clamping guides when you place your order and we will gladly include them for you.
If you have a very wide and large door, you might consider ordering a straight Sing beam to keep the top and bottom of the door in process perfectly straight in addition to the temporary guide to make sure the door perfectly flat the entire length.
Let us know if you would like sing beams added to your order and we would be happy to oblige.
The flatness of your door depends on how flat your sections are when they cure. Any warping in the mold will be retained once the glue drys, so it is vitally important that you clamp up your sections precisely straight.
Even though you find the best custom pivot doors with Sing Core inside in the best million dollar homes in the world doesn’t mean you have to be a billionaire to have such prestigious custom doors in your home.
All custom doors considered, custom front doors present the greatest challenge for the manufacturers, especially if they are custom wood doors. Specifying custom wood doors sounds easy; just spec the size of the wooden door, the type of wood you or your client wants to see and the type of door operation, such as a “pivoting;” although, it’s not quite that easy.
For instance, on a 16 ft tall pivot front door made of teak in a high end luxury home many factors come into play. In the first place wooden pivot doors over 7 ft tall are going to warp. This is the primary concern of the pivot door manufacturers, followed by matching the door with the appropriate pivot hinge and other pivot door hardware. Then there is the installation. The size and the weight of the door can cause a great deal of concern in handling, transportation, and installation of the custom pivot door.
Pivot Front Door
A pivot front door leaves a lasting first impression when someone first encounters the structure. To focus on this unique design element opportunity architects and designers are opting for pivot entry door which are large in size and feature an elegant wood grain. The nature of the pivot front door poses challenges because pivot entry doors traditionally face two varying climates, one on the inside of the structure and the other the exterior which may be exposed to the elements and various weather conditions. This is the perfect recipe for a warping pivot door.
Unlike hinge doors, which have hinges along the side of the door to help keep at least one side of the door from warping much, the pivot hinge is anchored only at one point at the top and the other on the bottom of the custom pivot door. That’s it. Unlike hinged doors, you cannot add an additional pivot hinge to help keep the door straight.
Warp-free Pivot Front Door
The advantage of seeking out a proficient custom pivot door manufacturer, is relying on their years of experience in working with specialty custom front doors over their service life. They know what will work, and what will cause problems over the life of a custom pivot door’s service record. They are aware of the challenges faced in dealing with large custom wood doors, and know there is only one way to build wooden pivot doors that will not warp, and that’s with patented Sing Core inside.
50 Year Warp-free Guarantee
Most custom pivot doors are exempt from warranty, or may carry the customary one-year warranty because (and the client is always informed of this before the contract is signed) it is likely that the custom pivot door will warp. Warped pivot doors will create problems for the doors operation, adding pressure to the pivot door hardware and will likely prevent the custom pivot door from securing correctly. While a warp-free custom pivot door will always seal and operate superbly. And unlike any other custom pivot door made today, only custom pivot doors with Sing Core inside are guaranteed not to warp, bend twist, or otherwise fail (including full structure warranty) for 50 years.
Save On Expensive Pivot Door Hardware
Another huge advantage of building your custom pivot door with Sing Core inside is that the resulting large pivot door will weigh in at a fraction of other large custom pivot doors with solid pivot door substrates. The key, here, is the use of a patented vertical grain torsion box/recycled rigid foam insulation composite resulting in the high performance solid core that is high strength (660+ PSI) which is stronger than steel pound-for-pound, yet adds very little weight to the door. Lighter weight custom pivot doors means you save thousands of dollars on pivot door hardware because the hardware is based on the weight of the door.
No more paying many times the price of your custom pivot door on just the pivot door hardware to operate the pivot door safely and securely over time.
That leaves more for your budget to spend on the expensive pivot door hardware that you can see, like the handle on this 16 ft tall teak pivot door which cost many thousands of dollars.
You’re in Good Hands with Sing Core
When you trust the warp-free experts at Sing Core with the inside of your custom pivot doors, you know they will support your core values with their best efforts to deliver only the best custom pivot doors possible to your most discerning clients with high expectations.
