Big Sliding Doors

Welcome to the world of big sliding doors, where we bring all your biggest sliding door dreams to life and guarantee worry-free enjoyment of your warp-free big sliding doors for 50 years.

Thanks to the patented and patent-pending technologies provided by inventor, Peter Sing, for the first time, you can enjoy the biggest sliding doors of all without all the headaches and problems associated with large, oversized doors.

Sing’s door core allows the warp-free door factory located in Washington State to build the most Eco-friendly, lightweight and super-strong big sliding door which will not warp, and as you know, heavy doors that add wear and tear to the structure and hardware, as well as door warping are the biggest challenges associated with big sliding doors.

So, what kind of big sliding door do you have in mind?

Our most popular big doors are wooden sliding doors. They might not be the most popular sliding doors in the world, but here, at Sing Core, the wooden large sliding door is in the most demand. Why? Because natural wood is notorious for moving according to changes in the environment.

And in most cases, the bigger the sliding door, the bigger the problems you will have with that particular door over time. It’s just the nature of the business, and specifically natural wood, is by far the most beautiful but impractical. That is, until the invention of Sing Core.

Sing’s True Flat Team helps to engineer or re-engineer big sliding doors to adhere to high performance standards which are unheard of in the industry. Sing’s core is the highest precision (+/- .006 in. tolerance) and highest strength (660+ PSI) lightweight and Eco-friendly large sliding door core in the world. This in combination with Sing’s anti-warp stiffening technologies can help to create a big door that can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years, regardless of the material it is made of.

Of course, Sing’s proprietary anti-warp science is unique to his reinforced vertical grain torsion box hybrid core and unique integration of warp-reversing technology, and the results are not duplicatable outside his factories which are primarily located in Washington State, in the Pacific Northwest.

Most of Sing’s clientele admits,

“There’s just no other way to do it, without Sing Core.”

How else could you make a lightweight failure-proof huge moving wall system with enormous gliding doors or large operable wall systems with big sliding door panels made of wood that are fully insulated, stronger than steel pound for pound, and warp-free, even if one side is fully exposed to the weather? Impossible. That is, unless you have such a system engineered and built with Sing’s core inside.

According to Sing,

We Can Make Any Style of Door

Now, this is an interesting concept. One that is used in high security impact resistant doors with Sing Core inside. For instance, Sing’s True Flat Team, helps to design large modern sliding doors that look like they are built with traditional style and rail door technology. The truth is, the door base is solid composite patented Sing Core, where the door skins are applied in pieces to duplicate the look and feel of stile and rail design.

If you were to kick a stile and rail door at the seam, the door would cave in. Sing says, “If you kick my door, you break your leg,” not Sing’s door.
Plus, the added insulation offers both sound deadening and climate control capabilities to your big sliding door that you would be hard-pressed to find any other way.

So, whether you’re looking for expanding your scenic access to the outdoors with large sliding glass doors, big patio doors, which would be like a wall of large sliding French doors, or a huge double sliding patio door, maybe you should be considering jointly engineered large scenic sliding door systems designed and built in concert with Sing’s True Flat Team.

Well known for his “unbreakable mirror,” you might also want to consider, as many have, using Sing’s services for your next large mirror sliding door project.

Wooden Sliding Door

Introducing the next generation of warp-free wooden sliding door with Sing Core inside. A genuine hybrid of old world and new space-age technologies melded together to create a uniquely new type of wooden sliding door which is changing the way a door, especially a large wooden sliding door is made.

 Eco-friendly Wooden Sliding Door
 Lightweight Wooden Sliding Door
 High Strength Wooden Sliding Door

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.

What is the width of a normal sliding door?

Typical sliding doors, including sliding barn doors, are 42″ wide in the United States, although they may range from 36″ to 48″.

Standard sliding door size are:

1. 42″ x 84″ x 1 3/8″
2. 48″ x 84″ x 1 3/8″
3. 36″ x 84″ x 1 3/8″

For wide doors in a limited space it is common to double up doors using two doors which open in opposite directions, or an increasingly popular option are pivot doors, which offer the grand feel of a wider than average door while maintaining space savings and usability.

What is the standard width of a bathroom door?

The most common size for a bathroom door is 32″. Your sliding door, such as a sliding barn door, should be taller than the door opening (allowing for sliding door hanging hardware) and wider as well (usually 1 to 2 inches on either side). Although, in tight spaces bathroom door openings can be as little as 28″ or 24″ inches wide. For spaces that require wheel chair access, doors should be at least 36″ wide to accommodate all ability levels.

When building a bathroom door, be sure that you have considered every eventuality. Particular to bathrooms are concerns about moisture and sound penetration. SingCore panels are particularly suited to harsh environments. We guarantee the structure of our panels for 50-years, which means you are able to count on your bathroom door functioning flawlessly for years to come.

Further, we offer patented foam and wood cores that significantly reduce noise propagation compared to commonly found door designs. Keep your private time private with SingCore.

What is a standard sliding height?

Standard sliding doors in the United States are 84″ tall (7′) and between 36″ and 48″ wide. The most common width is 42″, but may be as wide as 48″ depending on the width of the door opening. Be certain to allow for one to two extra inches of overlap on both sides and at the top of the door opening.

Standard-size exterior sliding door size

Typical exterior barn doors in the United States are 84″ tall and 42″ wide. There is some variation in width from 36″ to 48″ inches. 48″ wide doors are recommended to allow for easy access for the disabled.

SingCore also offers “standard oversize” doors at 8′ by 4′ that are suitable for designs that stand above the crowd without excessive expense. In particular, we are well known for our work with oversize pivot doors, custom sliding barn doors, metal skin doors, and solid “wood stave” doors for higher end applications.

Standard bathroom door size

Standard Size Sliding Doors

Although there is no standard door size, the majority of the bathroom doors in the US are 80″ tall and 32″ wide. Some doors vary between 28″ and 36″ wide. Be sure to measure your door opening, adding extra 1 to 2 inches all the way around for proper door opening coverage.

American standard sliding door size

Although there is no mandatory standard size, interior doors are typically 84″ tall and 42″ wide, while exterior doors are typically 84″ tall and 48″ wide.

Proudly Made in America

Standard sliding door height

Since most door openings are 80″ tall in the United States, 84″ is the recommended height of your sliding door, or barn door.

For a unique or above average look, SingCore recommends 95.5″ tall door openings for installation in a typical residential home, and taller for multimillion dollar homes or commercial spaces with high ceilings. Noe these will require a custom sliding door solution.

Inventor Peter Sing empowers any ordinary sliding door company to make extraordinary sliding wood doors which can be of enormous size and guaranteed to remain warp-free, including uncompromising structural strength for 50 years. No other company can do that, unless your wooden sliding door has Sing’s secret ingredients inside.

Mr. Sing’s True Flat Team at his Sing Core factory tucked away in the serenity of the plush Pacific Northwest in Washington State, utilizes varying formulations of his patented and patent-pending technologies to produce these one of a kind warp-free wooden sliding door products.

While many of the doors which feature Sing’s “Sing Core” inside their doors are the homes, establishments, and industrial sites of the most elite individuals in the United States and the world, Mr. Sing would like to see every interior sliding door, from closet sliding door to sliding carriage and barn doors featuring his core material in every home.

  7. Feature Any Wood Species (subject to availability)

  8. Available in Any Style

  9. Any Size (up to 40 ft., or more)

  10. 50-year Warp-free Guarantee

Due to Sing’s doors being so lightweight, think of the cost savings over the life of your wood sliding door in wooden sliding doors door hardware over time. The initial cost of hardware is based on the weight of the door, the greater the weight of the sliding door, the more expensive the hardware is. Sometimes the sliding door hardware can be more expensive than the sliding door, itself.

Heavy wood sliding doors will present regular maintenance costs over time, as the weight of the door under normal usage conditions will cause the hardware to beak down, requiring service or replacement. These heavy doors also exert stress on the structure over the course of normal operation which leads to other structural maintenance costs over time.

If your wood sliding door has Sing Core inside, the weight of the door will be very light, saving you money on lighter weight-rated sliding door hardware. Plus, regular operation of the Eco-friendly, lightweight and high strength door does not wreak havoc on the structure, which means very little maintenance over time, if any, which greatly reduces the average cost of wood sliding doors overall.

The most modern sliding patio doors and modern sliding barn doors have Sing Core inside as contemporary architects and designers let their creative juices flow thanks to Sing’s invention of Sing Core.

These are often considered among the best wood sliding doors and by far the best-performing gliding patio door as Sing’s invention makes child’s play of the challenges associated with a wood sliding door with one side 100% exposed to the weather (which usually creates many problems for door manufacturers in the field following installation).

If you, or your client, demands the highest degree of stylish sliding doors which can continue to be proud of and can be guaranteed for 50 years of worry-free enjoyment without fail?

Shouldn’t your wood sliding doors (at least the most special ones) have Sing Core inside?

How can you get the best wood sliding door in the world?

Surprisingly, you cannot get a door from Sing Core. Inventor Peter Sing says,

“We do not make doors.”

Which is a little confusing because he does provide the best sliding door manufacturers in the world, as well as custom door makers, and millworks, with his patented core systems to enable them to create these enormously famous one of a kind doors.

Wood Sliding Doors

Wood sliding doors are by far the top sellers of all door types besides hinged doors of any kind of doors. Wood sliding doors serve a wide variety of applications from residential to hospitality, business, commercial, and industrial wood sliding doors.


A wood sliding door is a very elegant statement in nearly any environment, and can be operated by hand, or electronically articulated and operated by remote control. Remote control wood sliding doors can have problems when operating a large sliding door which is very heavy over time.

If you’re replacing a wooden sliding door, you might consider reducing your regular maintenance costs over time by obtaining wooden sliding doors with Sing Core inside, which provides you with a lightweight impact resistant wood sliding door that is fully insulated and stronger than steel pound for pound.

Modern sliding barn doors are among the most popular trends in interior sliding doors of late, and a large wooden barn door is definitely the most challenging to attempt of all sliding door systems, because the more wood grain in the sliding barn doors, the more tendency they will have to warp, unless you have a warp-free Sing wood sliding barn door.

Inventor Peter Sing is famous for providing the highest precision and functionality in large lightweight wood sliding doors relieving the stress on wooden sliding door hardware as well as the structure, delivering high performance and each individual door can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years, regardless of size.

Sing’s modern sliding patio doors are the most impressive wood patio doors. Each one of these individual sliding glass doors is essentially a one of a kind piece of artwork, specially designed and engineered from the inside out by Sing’s True Flat Team. The individual characteristics of each of these modern doors results in every wood sliding door being specifically engineered to perfectly fit the application, exposure to the elements, type of sliding door hardware, impact resistance, sound deadening qualities, any type of exterior surface material.

If you’re in search of the ultimate sliding patio door, you pretty much need to have Sing Core inside, if you want a high precision gliding patio door, which outperforms all other sliding glass patio doors. Now, thanks to Sing’s invention, you can have sliding patio doors that are commonly referred to the best patio sliding doors. It’s no wonder you find them in the most expensive multi-million-dollar homes in America.

The most common sliding French wood patio doors you find with Sing’s core inside are the perfect balance between wood and glass, with a beautiful wood frame holding transparent glass in the center of the sliding French wood doors.

The insulation value of Sing’s core allows him to provide both sound dampening and climate control to wood sliding doors, either on purpose, or as a pleasant added benefit, even if you’re designing a custom wood glass sliding closet door.

Often referred to as the best sliding wood doors, sliding doors with Sing Core inside are the latest evolution of sliding door ideas, since, (well, sing forever).

So, how would you go about obtaining sliding wood doors with Sing Core inside for your home? It really is very easy, but you won’t get them from Sing’s factory. The inventor is very clear in his assertion that,

“We do not make doors.” ~ Peter Sing

How can that be, when Sing’s doors are featured in so many of the most upscale projects in the world?

According to the inventor and CEO, Sing Core only provides the base door or sliding door blank to the millwork, door manufacturer, or custom door shop. The rest is up to the other professionals to finish creating this work of art, as well as installation. It takes a village to design and build the best wood sliding doors.

You are not limited simply to wood doors, as Sing Core also supplies the world’s biggest and best door companies with large custom aluminum wood multi slide door blanks and large aluminum wood sliding doors. See our new C Series line of Affordable Barn Door and Sliding Closet Doors.

Custom Sliding Door

The new and improved custom sliding door projects at Sing Core are always exciting as they specialize in solving the problems associated with large custom sliding doors for the most expensive homes in the world as well as custom & replacement doors for closets, media rooms, garages, bedrooms and offices.

While the biggest custom sliding door presents many problems to the contemporary architecture and design firm, using the finest large sliding door engineers, Sing Core reaches out offering solutions to any of the problems which may be faced when trying to create a visionary’s custom sliding door ideas to life.

Sing’s True Flat Team at Sing Core rises to the task every day to take the headache out of realizing your custom sliding door vision, especially if you are struggling with a large sliding door opening, and wrestling with a building material which is difficult to keep straight, such as the case of natural wood sliding doors.

Natural wood presents the biggest problem for door manufacturers because wood moves, what we in the business call, “door warping.” There is little pride associated in building any custom sliding door that will warp months or weeks after installation, regardless of how beautiful it might be.

Enter Sing’s invention of Sing Core, the only way to build an Eco-friendly lightweight custom sliding door that is stronger than steel pound for pound (independently tested at 660+ PSI) and can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years.

The most problematic large sliding doors are exterior sliding doors because one side faces the interior of the structure while the other side may be one hundred percent exposed to weather. This is the perfect recipe for warping doors, unless they have Sing’s patented core inside.

Which makes the Sing solution a perfect match for custom made patio doors which could be made of any available flat building material, which not only gives you a true flat, warp-free panel sliding patio door, but you get the added safety and security that comes from having insulated custom patio doors.

Sing’s custom sliding glass and hinged patio doors are the contemporary glass opening approach to having that French door design access connecting the structure’s interior with the outside whether doors are secured or wide open for the most modern sliding patio doors. This also makes the Sing solution the top resource for replacement sliding patio doors which may never need replacing again.

The fully embedded insulation in Sing’s hybrid design sports an R-value of 3.5 to 6.5 per inch in thickness, assuring you more safety, security, privacy, and climate control with fully customized sliding doors for your home that are beautiful, and energy efficient impact resistant doors.

Peter Sing works together with the contemporary architects and modern designers to create custom made sliding doors unique to the design, function, and high precision expectations while delivering the best dimensionally stable results possible with his new hybrid custom sliding door technology, available in nearly unlimited and extreme custom sizes.

So, if you’re looking for bringing your superior custom sliding door design to life, regardless of size and limitations of your most desired materials, Sing Core can help to bridge the gap between what was previously impossible and the birth of all your replacement and new oversized sliding doors.

To either create or re-create your indoor/outdoor living space with custom sliding doors, all you have to do is to contact the sliding door company of your choice and tell them what you want. Give them the specs of your dream door, including the height, width, and thickness, as well as what material you would like to have the door made of, and don’t forget to tell them you want, “Sing Core inside.”

No two sliding doors are the same as Sing’s 100% custom sliding doors are created with the love and care of fine handcraftsmanship in his factory nestled in the scenic Pacific Northwest in Washington State. Even though his location is somewhat remote, Sing Core ships every day to destinations across the United States and around the world.

While Sing Core is a replacement door company offering sliding entry doors and entry door replacements, “We do not make doors,” says owner/inventor, Peter Sing. Sing’s company provides a unique service to manufacturers of custom architectural wood windows and doors in the greater Seattle area.

Sing’s invention (Sing Core) is a combination of his patented insulated reinforced vertical grain torsion box core combines with other patent-pending anti-warp technology to provide a base door blank to the millworks and custom door manufacturers which is fully insulated, a fraction of the weight of other solid wood-based door cores, yet is so strong that the inventor can stand on this one-inch thick panel with a clear span between two saw horses with little deflection. This is just one example of how strong Sing’s door core is.

Note that Sing’s core was independently tested at the University of Washington whose results rated his invention at 660+ PSI. Compared to other lightweight cores used in the aerospace industry, which are rated at 10 to 110 PSI, the possibilities are hard to comprehend.
