Sing wooden doors make the best wooden doors in the United States and around the world. No other Eco-friendly lightweight wooden door core is stronger. Weighing in at a fraction of the weight of solid wood door core, patented Sing Core is stronger than steel pound for pound (660 PSI). This is the only way to make a large oversized wooden door that can be guaranteed not to warp, bend twist or otherwise fail for 50 years.

Sing Core Wooden Doors
Each professional Sing wooden door can be guaranteed to remain warp-free for 50 years, including a full structure warranty. This is why Sing Core wood doors are making such a huge impact on the door industry across the USA and abroad.
Any type or style of wood door can be made with Sing Core inside, such as exterior wooden doors, wooden barn doors, interior wood doors, wooden sliding patio doors, wood sliding room dividers, wooden French doors, wood stile and rail doors, just to name a few.
Patented Eco-friendly wooden doors with Sing Core inside are proudly made in the USA, using sustainable manufacturing methods using less energy, with responsible use of recycled and renewable resources, including natural wood fiber, producing little or no waste or loss of energy, leaving a negligible carbon footprint.
There is just no other way to make 20 ft. tall wooden doors that will not warp. Wood is a very difficult resource to use for anything over 7 ft. tall because of its tendency to move, especially in exterior wood doors. For instance a wood door that faces the elements on one side and the structure’s interior on the other is going to warp. That’s why no door company guarantees warp resistance of a wooden door for more than one year, that is, unless it has patented Sing Core inside.
So, how can you get wood doors with Sing Core inside? It’s easy, just go to your favorite architect, door manufacturer, mill work, or custom door company, and tell them what size door you want and be sure to ask for, “Sing Core inside.” We cannot sell or ship Sing Core doors directly to consumers or do it yourselfers, as we are the manufacturer supplying Sing Core door core only to door manufacturers and builders of custom doors.
Big Oak Doors
Here’s an example of a pair of 10 x 12 big oak doors, 3-inches thick. These are made using solid oak wood stave (or planks) trimmed thin at 1/8-inch and applied to patented Sing Core engineered substrate.

The face staves or planks are expertly applied and nearly seamless. If done any other way, these face staves will separate or crack due to movement of the surface area, but because Sing Core does not move, this surface area will remain in pristine condition thanks to inventor Peter Sing’s warp-free contribution to the large wooden door industry.

The secret to making a big oak door, like this, look like a solid oak door is to use matching oak grain stiles and rails for framing. So instead of edge-banding on the panel sides, you see solid oak wood edges which gives this the impression of being a big solid oak wood door.

Wood Stave vs. Wood Ply
Wood stave doors can be very costly to make, especially if you’re looking for a lightweight high strength solution for a warp-free guarantee for 50 years. Using Sing Core inside your wood stave door featuring wood planks from 1/8-inch to 1/2-inch will create more potential for warp due to the nature of natural wood grain. This is the beauty of the more economical wood ply option for building your wood door. Wood ply is far less expensive and has alternating grain orientation which also helps to keep the door straight. Wood plywood is just like any other plywood except for its featuring a particular wood grain predominantly on the surface, and it offers far more strength and reparability over time than a less expensive wood veneer. So, if you’re looking to attain similar visual results of a solid wood door at a fraction of a price you might consider having Sing Core inside your wood plywood door. Be certain to specify what type of natural wood plywood your want, if it is available, you can save thousands of dollars on your beautiful wood door. The most popular wood plywood features woods such as white oak plywood, maple plywood, oak plywood, mahogany plywood, walnut plywood, Douglas fir plywood, knotty pine plywood, and birch plywood just to name a few.
Large Wooden Doors
Large oversized wooden doors are the greatest hurdle facing architects and designers, because though there is little more impressive than a huge wooden door to catch your attention, so the bigger the better, but then there’s the issue with warping, which is a constant struggle for the owner to secure regular maintenance of such a beautiful wood door, likely at least seasonally.
Thanks to having Sing Core inside, you will never have to worry about warping wood doors again. While they are built to last for centuries, each professionally guaranteed Sing wooden door can be non-warping and include a full structure warranty for 50 years. No other Eco-friendly, lightweight, high strength wood door can have such a guarantee in the world.
And what if you’re looking to build a large door out of a material other than a natural wood grain? No problem, your doors could be made out of any available flat building material, such as aluminum doors, cement, concrete, fiberglass (FRP), glass, HPL, Kevlar, LVL, MDF, steel (cold rolled steel, steel diamond plate, galvanized steel, hot rolled steel, etc.) as well as the only unbreakable mirror doors, just to name a few.

When it comes to metal doors, Sing Core is one supportive resource behind the scenes that you may not be aware of, and is the proud creator of some of the best metal doors in the industry.
Although metal doors are traditionally incredibly heavy, Sing Core technology gives architects and door manufacturers the ability to create lightweight doors without compromising strength. This is especially true if you are looking for security doors. Additionally, our doors also have the added benefit of being eco-friendly, made in the USA, insulated, and sound-deadening.
It’s very important that doors be operable, especially pocket doors, bypass sliding doors or double sliding doors. If your metal doors are large in size, or in use as steel security doors, then other challenges must be taken into consideration in the architectural design and specification of your metal doors.
Metal Automatic Sliding Door
When looking for the best metal automatic sliding doors, you want hassle-free installation, low maintenance, and high-quality doors. If your sliding door is missing any of these components, it causes undue stress on the automatic sliding door hardware and the structure that houses the hardware. This can lead to more expensive maintenance issues over time. However, Sing Core doors can avoid these issues by providing lightweight, high-strength, and warp-free door cores that are guaranteed to last for up to 50 years.

Serving the Top Metal Door Manufacturers in the World
Sing Core provides professional Sing Core metal door core to the top four metal door manufacturers in the world enabling them to create a high precision, high performance custom metal doors. All our products are Eco-friendly, made in the USA, lightweight, and high strength. Our metal doors are guaranteed not to fail for 50 years. You get the ultimate door and core that the planet has to offer.
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.

Sing Core has been assisting the best high end custom door manufacturers create the most magnificent swinging doors using the best hinged door known. Only the best, most exclusive upscale architects, designers and ultra-custom door makers know if you want the best hinged door for the highest degree of precision, performance and prestige, you want your door to have Sing Core inside.
Hinged Door Warp-free Hinged Door Guarantee
Building a door with Sing Core inside is the only way to create a door that can be guaranteed not to warp, bend, twist or otherwise fail for 50 years, including a full 50 year structure strength warranty. While other doors may be guaranteed for 10 years, most or one or two years, if they are guaranteed at all. Doors over seven or eight feet tall are normally excluded from any warranty due to their tendency to warp the next season.
With Sing Core you can create Eco-friendly swinging hinged doors that are insulated, lightweight, high strength. No need to add extra door hardware to help keep the door straight over time (door manufacturers add extraneous hinges in an effort to keep the door straight). But warp-prone hinged doors, even if they have a full length piano hinge, still warp on the side that latches, and a door that does not operate and cannot be secured is not much of a door at all.
Airtight Hinged Door Seals
Maintaining a perfect airtight seal is of primary importance, plus the added insulation characteristics of any door with Sing Core inside increases climate control while adding sound-deadening qualities not found in other doors, especially in high end laboratories, industrial environments, commercial applications, and homes.
Superior Exterior Hinged Door Applications
Exterior hinged doors often cause problems (especially if they are over 7 ft tall) because one side of the door faces the interior of the structure while the other side of the door faces the elements.
Hinged Panel Doors
Panel doors are assembled of wood (or other material) with separate pieces oriented in cross grain patterns to help mitigate the potential door warping. While this method is somewhat effective, the resulting door does not offer much in the way of high precision, insulation, or performance, but they are pretty. The craftsmanship of a well-made stile and rail door is very elegant and the way the different pieces are joined together offers a certain intrigue when examining the door, especially if it is a wood grain door. But consider the Sing solution…
Sing Raised Panel Door
The Eco-friendly Sing raised panel door is a huge improvement over the traditional stile and rail door, in that it is extremely high-precision (+/- .06 in.) lighter in weight (a fraction of the weight of those solid wood panel doors), insulated for climate control and sound deadening, and stronger than steel pound of pound enabling professional raised panel doors with Sing Core inside to be guaranteed warp-free (will not warp, bend twist, cup or otherwise fail) for 50 years, including full structure warranty. No other door can do all that, and be so versatile.
While a Sing raised panel door can look just like a standard 6 panel door made via the old-fashioned stile-and-rail door manufacturing method, making a raised panel door with Sing Core inside is quite different.
The most important component of the Sing raised panel door is the patented Sing Core material which consists of a hybrid composite of vertical grain torsion box grid filled with rigid recycled foam insulations sandwiched between two stress skins and superiorly bonded with formaldehyde-free adhesive. This gives your door the strength and integrity you’ve always dreamed about. Install the door, and no worries about service calls due to door warp.
The Best Millworks and Custom Door Manufacturers
The best millworks and custom door manufacturers know that the only way to deliver a truly premium product to their high end clientele is to provide them with doors which they make with Sing Core inside, enabling them to guarantee their doors for 50 years, backed by Sing Core’s written guarantee. We take all the hassle and risk out of delivering the best base materials for the best companies and their best customers, bar none.
The Best Flush Doors
Sing Core provides door manufacturers with the best door blanks and flush doors to be used as the best canvases to showcase the artistry and craftsmanship of the finest custom door makers in the world.
Again, if you want to make your Sing flush door look like a panel door, like, say a 6 panel door, the door artisan simply adds the 6 panels and trim to the door’s surface. This is a common approach, especially in door replacement of historically preserved architecturally challenging maintenance and upgrades.
Sing doors are often considered the best replacement doors, especially in exterior door replacement due to the weatherproof door’s characteristics.
Your flush doors with Sing Core inside can easily be modified by adding custom molding, trim or cutting custom lite cutouts for glass installation in any shape at any location to achieve your desired results.
“How can I get doors with Sing Core inside?”
It’s easy. All you have to do is to contact your favorite millwork or custom door manufacturer and tell them what kind of door you want, including the height, width, thickness, style and look you want (you can even bring in a picture of one that you’ve found in a book, magazine, or on the Internet. They will work in concert with Sing Core to make all your door dreams come true.
You can be among the growing many who can proudly proclaim that their doors have, “Sing Core inside.”
Sing Core’s Sing Log Homes are highly regarded as the best log homes in the world due to the patented technology of Sing Core as applied to traditional wood logs resulting in the only insulated logs which would not warp, twist or crack; nothing short of revolutionary in a market that was constantly challenged by Mother Nature throughout the entire build and life of the log home structure.
It all started with the decline of the log home industry, in combination with the request of several patented Sing Log Home builders insisting that their large doors also be made with insulated Sing Core. At about the same time, people started inquiring about the possibility of using patented Sing Core without the log configuration, and the Sing Panel was born.
The main attention-grabbing draw of the Sing Panel was the best of two worlds; patented vertical grain torsion box/rigid recycled foam composite sandwiched between two stress skins with formaldehyde-free adhesive. Institutions, like NASA and branches of the United States military and research labs across America quickly took notice and started researching Sing Panels for a wide variety of applications.
The resulting Sing Panels were lightweight, extremely strong and had tremendous shear strength and resistance to deflection, something that almost challenged the law of physics in building materials. Sing Panels were independently tested in university laboratories and rated at 660 PSI and up (compare that to the 10-to-110 PSI of other honeycomb materials used in aerospace industry), depending on the configuration.
Now, large doors, extremely large doors (up to 50 ft. or more) could be made using this new patented building material… and no one knew how valuable a resource this would be to the entire door industry.
Before long, more and more people were realizing that doors made with Sing Core inside were out-performing AWI standards for door warp over and over again, setting a new standard for warp resistance.
5o-year Warp-free Guarantee
Based on a combination of independent research, scientific method, field studies, the introduction of a new stiffener technology (patent pending), and experience, Sing Core was able to deliver doors with the highest degree of precision and performance backed by an unheard of 50 year guarantee, which states:
Sing Core guarantees certified professional doors of any size not to warp, bend, twist, cup, or otherwise fail – including full structure warranty – for 50 years.
Of course, in order to be professionally certified, the True Flat Team at Sing Core must be involved with the design of the door and the door will only be guaranteed for the use for which is was built for because different applications require different approaches to assure their 50-year performance.
Widely renowned as the best way to build the best large doors in the world, it is not uncommon for people to think that Sing Core builds doors. This is not true.
Sing Core does not make doors
Sing Core does not make doors, yet the best large doors in the world are made with Sing Core inside.
While Sing Core does not make doors, we do supply the best ready-to-build architectural door materials which are shipped directly from our factory to the millworks, door companies, and custom door manufacturers who add the finishing touches to the Sing door blanks.
The resulting Sing Doors are the culmination of a team effort from the architect, designer, engineer, millwork, fine craftsmen, and Sing Core’s True Flat Team. It is only due to their combined efforts that Sing Core looks and performs so well when it is enjoyed by the end user.
The part patented Sing Core plays in the door industry is similar to jet engine manufacturers in the aerospace industry. Jet engine manufacturers do not build their own aircraft, likewise, Sing Core does not build pivot doors, we only supply the warp-free substrate used by pivot door manufacturers to build lightweight, high-precision doors that do not warp.
Latest in Pivot Door Technology
The latest area of expertise where Sing Core shines through among the door industry is in the area of pivot doors. Pivot doors are unlike regular hinged doors in that they are traditionally larger, thicker and heavier than other types of door. Plus, they only have two points of contact for anchoring, unlike a hinge door. (Hinge doors can help to minimize warp to some degree by adding additional hinges or hardware to help keep the door straight.) Not so, with pivot doors.
We do provide lightweight, high strength and warp-free components to build the best pivot doors. Click to See How this Works
Our stock items are warp free with structure guaranteed 4×8’, 3” thick pivot door blanks for $499 each ($2500.00 value).
Our latest foray into the world of pivot doors has been wildly successful, which also allows us to have access to the latest in pivot door technology, such as the new FritsJurgens hidden pivot door hardware.
Our growth in pivot doors is growing to meet the volume of large sliding doors that we provide to an industry where keeping the door straight and true is also of great importance. For what good is a sliding door, if it is warped and unable to slide?
This can be particularly problematic when dealing with bypass sliding doors or pocket doors.
In any case, if keeping your doors straight and true is of primary importance in your project, there is only one way to build a door which can be guaranteed not to warp, bend, twist or cup for 50 years… and that’s to have,
“Sing Core Inside.”
Sing Core panels have been used as sliding door core, hinge door core, and French door core with guaranteed non-warp and full structure warranty for 50 years. You, too, can have the best guarantee serving the door manufacturing industry.
It is well known among the high end pivot door industry that Sing Core pivot door blanks are the only way to create the best lightweight, high-strength pivot door of any size (even extremely large in size) that can be guaranteed not to warp, bend, twist or otherwise fail (including full structure warranty) for 50 years.
Breaking News FritsJurgens Pivot Door Hardware
It’s no wonder the clients who use patented Sing pivot door core to build their high end doors are using the latest in leading edge pivot door hardware. While your pivot doors for the elite may feature any type or style of pivot door hardware made by any of the most popular pivot door hinge manufacturers, one new type of pivot door hinge is getting installed in more large pivot doors with Sing Core inside.
Breaking News
It has come to our attention that the new System M hardware from FritsJurgens in Holland is what all the latest buzz is all about.
What’s the big deal?
The big deal around Sing Core is always about big pivot doors. Not only big pivot doors but the biggest pivot doors because you could be talking about thousands of pounds of a large pivot door, which could be reduced to ten percent of the weight by having Sing Core inside.
Architects, our custom door manufacturers and millwork clients rely on the lightweight fail-safe aspects of pivot doors made with Sing Core to keep your project, not only at the elitist level of excellence, but within a reasonable budget. While those huge pivot doors can be very expensive to build and handle, the sheer weight of the door dictates the hardware necessary to accommodate such a door.
Installation of the hardware to operate an enormous pivot door can require extensive engineering efforts as well as becoming a burden on the installation, especially if it is being retrofit into an existing structure (not so bad if prepared for in a new structure being built).
Then comes along Holland’s FritsJurgens with the perfect match of sleek System M hardware that is the easiest pivot door hardware to install, especially in a retrofit application, carrying a weight of up to an 1,100 pound pivot door. That could be a 37 foot tall pivot door with Sing Core inside!

The pivot closer is concealed within the door, not the floor! Making this the easiest to install pivot door hardware, requiring very little modification at the job site to install. Some of our custom pivot door builders are able to transport a completed pivot door system fully installed and pre-hung from their factory or millwork to the job site for the easiest installation of pivot doors ever, thanks to FritsJurgens’ System M nearly concealed hardware.
If you’re using a Sing pivot door blank for your pivot door substrate and you plan on using FritsJurgens’ System M pivot door hardware, all you have to do is let our design staff know when you’re placing your order. Sing Core can pre-install the required blocking necessary to accommodate the FritsJurgens System M pivot door hardware.
If you’re upgrading an existing non-Sing pivot door to a pivot door with Sing Core inside, you will be glad to know that FritsJurgens’ new System M closer works with existing FritsJurgens top plate and top pivot.
At present, this is a leading-edge well-kept secret among the most elite high end custom door manufacturers, but we thought you would like advance notice before this product becomes more widespread in use across the United States.

It is clear that not all interior sliding doors are the same. You never know when you might be seeking out Sing Core for your interior sliding doors. While they are primarily featured in large exterior sliding doors due to their lightweight and high strength as well as their ability to be guaranteed not to warp, bend, twist or otherwise fail for 50 years. It’s a tall order, but there’s only one way to accomplish such a feat with an exterior sliding door and it requires having Sing Core inside.
When architects and designers are working on very high end homes (i.e., multimillion dollar estates), their clients want only the best, so they seek out characteristics which can only be attributed to Sing Core. Besides giving the best door companies, millworks and custom door manufacturers the ability to make big interior sliding doors (tall, wide and thick) that are lightweight and high strength, they also feature insulation for sound deadening capabilities and climate control.
Lightweight Modern Door
Interior sliding doors with Sing Core inside can feature any available flat building material on the surface of the interior sliding doors such as any species of natural wood stave, aluminum, cement, concrete, fiberglass, FRP, glass, HPL, Kevlar, LVL, metal (brass, copper, etc.), and steel (including cold rolled steel, diamond plate steel, galvanized steel, hot rolled steel, and stainless steel), just to name a few. So, the possibilities are vast, indeed.
Not just exclusive to the very wealthy, sometimes homeowners just want to have the best (you know who you are), and they have their architects, designers and door companies seek out Sing Core for their interior sliding doors also. Just know that we do not make or sell the interior sliding doors for which we are credited with. We only supply the raw material to the door companies, millworks and custom door makers who make us and doors with Sing Core inside look so good. While we do not deal with the end users, you can have your trade professional(s) deal with us directly.
Some of the best uses of interior sliding doors with Sing Core inside include,
Closet Doors
Closet doors are probably the number one interior use of interior sliding doors with Sing Core inside, especially in very large homes with large closets. In some of these huge homes and estates, the closets can be as big as a normal-sized living room, or an entire small house. These wardrobes can go far beyond what you might think of as a walk in closet, requiring large sliding wardrobe doors. See our new C Series line of Affordable Barn Door and Sliding Closet Doors.
Often high end closets are climate controlled, all but requiring sliding closet doors with Sing Core inside to complete the safety and security of the temperature and humidity maintenance without wasting unnecessary energy, which also support the Eco-friendly attributes of the most modern closet doors featuring Sing Core.
Of the many types and styles of closet doors being shipped from Sing Core include bifold closet doors (as well as other folding closet doors), closet barn doors, French closet doors, wood sliding closet doors and our classic unbreakable sliding mirror closet doors. And remember, they can be made of anything from beautiful, exotic natural woods to any metal, including silver plate or gold plate interior sliding doors.
Unbreakable Mirror Closet Doors
Ever since the introduction of the Sing Unbreakable Mirror, high end fashion custom door manufacturers have been sourcing Sing Core for their sliding mirror closet doors due to their impervious nature and the ability to create a high end mirrored sliding closet door that is not extremely heavy and potentially very dangerous, both to the weight of the door, and the fragility of the glass mirror surfaces of the sliding mirror closet doors.
Whether you’re a famous actor or rock star, if you want the best mirrored sliding closet doors, that offer both safety and security during the operation of the door (that can come with a 50-year guarantee), then you know you want all your sliding mirror wardrobe doors to have Sing Core inside. Hands down the only way to effectively create lightweight unbreakable mirror closet sliding doors.

Bifold Doors
Interior Bifold doors with Sing Core inside have the distinction of being the most exquisite high performance articulating bifold doors due to Sing Core’s ultra high precision (+/- .006 in.) tolerances. Again for those special jobs requiring large bi fold doors you are likely to encounter problems associated with warping bifold doors which may compromise the operation of these specialty interior doors altogether. With more moving parts, the importance of having non-warping bifold doors is of primary importance.
Internal bifold doors aren’t much good if the operation of the bi fold internal doors’ systems are failing due to warp, bend or twisting interior bifold doors. The same goes with folding closet doors of all kinds which operate with more than the normal number of hinges which might be used in standard hinged doors. Internal folding doors benefit widely when using Sing Core inside folding internal doors.
Sometimes the hardware used for interior bifold doors includes a combination of folding sliding and pivoting hardware in this type of folding interior doors.
Sliding Barn Doors
Interior sliding barn doors are gaining more momentum in the interior sliding door market every day. Contemporary architects are specifying Sing Core inside their large exterior doors, though there is a growing trend of specifying the patented Sing Core as substrate for sliding barn doors, too.
Why specify Sing Core for your interior sliding doors? Mostly because sliding barn doors are more costly than their hinged door counterpart, and the hardware is more expensive. The weight of the interior sliding barn doors determine the type of hinges which are necessary. This task is far easier than one might expect.
Simply weigh the Sing door blank and use the appropriate interior sliding barn door hardware. All hardware for sliding barn doors is determined by the weight of the door. Even though Sing sliding barn doors are more lightweight than other interior barn doors, qualifying them for using lighter weight-rated hardware for sliding barn doors, owners, project managers, designers and architect may elect to select higher-than-current-weight-rated hardware. Why?
Because, since the doors accommodate the higher opening and can be very tall and wide, the door designer can opt for a much thicker barn door (which would be next to impossible to build and still maintain a good strength-to-weight ratio). Large sliding barn doors would be much less impressive, visually, if the size and weight of the sliding barn door hardware was reduced to match the weight of the interior barn doors. Sliding barn doors made with Sing technology are far more attention-grabbing when viewed by professionals who cannot understand how such large doors can be operated with such sleek and lightweight hardware.
To maintain the visual impact of the modern barn doors the designer may opt for very heavy duty barn sliding door hardware to achieve the impressive appearance from the barn door interior.
Also, barn door closet applications are quite the rage as sliding barn doors continue infiltrate the market of closet doors. So, be on the lookout for indoor barn doors as they become more commonplace as barn closet doors. You can get Sing closet barn doors directly from your favorite local door company, millwork or custom door manufacturer.

Original 10×10 Cube Structure
Our original Sing Modular Cube Structure got its name from its effective and convenient 10×10 footprint format which resulted in a 10 foot wide, 10 foot tall, 10 foot deep structure, with a loft inside, providing extra storage and/or bunk/loft bed space, without sacrificing the valuable 10×10 floor space.
Highly Expandable
Due to the modular nature of the portable Sing Modular Structural components, the design of your modular structure is not limited in any way to a single 10×10 cube structure. You can reconfigure the components or add additional custom connectors, bridges or breezeways to suit your specific needs.
