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.

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.

  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.”

So, all you have to do is to contact you favorite door manufacturer, custom door builder, or millwork, and tell them you want “Sing Core inside,” your door.

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.

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.

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.

If you are looking for a custom manufactured sliding door system, you would be well-served to seek out inventor Peter Sing’s patented and patent-pending custom sliding door systems and solutions, resulting in Eco-friendly lightweight and high strength custom sliding doors which are built to last for centuries but guaranteed for 50 years.

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.

The number one delivery location is the greater New York area. It’s a good thing that Sing’s Custom-made sliding door blanks are so lightweight, that shipping them across America is far less expensive than other materials of the same size.

The rest will result in all your architecturally beautiful interior sliding door and custom sliding door dreams coming true for you and your most discerning clientele, all backed by inventor Peter Sing’s 50-year warp-free guarantee.

Sliding Metal Doors

Sliding metal doors were all the rage in commercial, industrial, and residential applications in the fifties and sixties. The only problem with these doors was that they were costly to maintain because these sliding metal doors were so heavy. It’s a lot of extra weight to add to a structure, especially if the structure isn’t manufactured primarily of concrete and steel.

Rollers would breakdown, bearing would fail, tracks would deteriorate, as the maintenance costs piled up over the lifespan of the door. Now, thanks to Sing Core, there is a solution for making Eco-friendly sliding metal doors which are lightweight, with Sing’s patented solid hybrid core.

The classic design and look of sliding metal doors are making a comeback in modern contemporary architectural designs and it is having huge impact, especially if the sliding metal doors are very large in size.

This new resurgence in metal sliding door design is implementing all types of metal, primarily focused upon aluminum door, stainless steel door, galvanized steel door, cold rolled steel door, and hot rolled steel door, in that order of popularity among modern architects and designers.

When contemplating the incorporation of a large metal sliding door into your design, there are many considerations to take into account. Will there be maintenance required regularly over the life of the door? In most cases, large doors will need regular maintenance to keep them functioning properly, and to repair or replace them if they either become damaged or start to warp.

Any metal door could be made of any type of available metal, though some types may be cost prohibitive, and others may be too soft to deliver consistent high performance over time, so it’s best to know your metals before you specify the material, unless, of course, price and regular maintenance are not an issue.

Aluminum and steel sliding doors definitely lead the pack over all metal sliding doors, and exterior steel doors are a hot item, and when they encounter direct sunlight, that’s when things start moving. That’s a problem which could prevent the steel sliding door from operating correctly and may cause undo stress on hardware, leading to all kinds of other problems.

When a warping metal sliding door is of concern, Sing Core is the solution, especially for modern metal doors over three-and-a-half feet wide and seven feet tall. Inventor Peter Sing can help architectural door designers to create large metal doors which can be guaranteed warp-free for fifty years.

In fact, if you have a large metal door with a 50-year warp-free guarantee, that door has Sing Core inside and it was designed, engineered, built, and finished to achieve those special results.

While Sing Core is found inside the best metal sliding doors in the world, Sing Core does not make sliding doors. Sing Core works hand-in-hand with the best millworks and metal door fabricators in the world. The result of this massive team effort to achieve such high-end sliding metal doors. No detail is overlooked.

It takes a village to build a lightweight, high strength, metal sliding door that is a one of a kind piece of work which is made to last for centuries and guaranteed to remain warp-free for at least 50 years.

Wooden Sliding Doors that Don’t Warp

When you need a large door that doesn’t warp, especially a sliding door made of wood, then look to Sing Core for you salvation.  No one is able to guarantee our wooden sliding doors don’t warp like we do, with a warp free 50 year guarantee.

How do you stop a wooden door from warping?

The easy answer is to buy Sing Core for your door. Our patented light weight torsion box material is able to withstand extreme conditions and maintain perfect straightness over the life of the door. Wood can always warp but sing core never will, despite being a wood and foam core. The aerospace inspired construction methods push the capability of wood to beyond the strength of steel pound per pound and lighter than an equivalent wood door of traditional construction

How do you straighten a warped interior door?

There is no easy way to straighten a typical wood warped door. But Sing Core’s patented and patenting pending aluminum stiffener technology, found in all “professional” grade wooden sliding doors we make, allows warped doors to rebound.

The process is simple to un-warp a Sing Core wooden sliding door that may have warped during transport or during storage before finishing and installation.

  1. Support the wooden sliding door on it’s side in a dry area
  2. Allow the panel to sit with equal circulation on both sides for 3-5 days
  3. Enjoy your perfectly straight sliding door panel

Once sealed and installed, perfect straight Sing sliding door panels will never warp.

JB Duke Hotel Doors Perfect Straight Light Weight Super HIgh Strength

Does staining wood prevent warping?

Staining wood does not prevent warping. Sing panels, once sealed with an appropriate wood sealer, will never warp. Traditional wood doors, however, are prone to warping even after sealing due to aging effects of the wood.

What causes cabinet doors to warp?

Traditional cabinet doors generally warp because of uneven moisture infiltration due to near by water sources such as sinks, showers, and steam from cooking. Everyone knows that wet wood tends to warp.

Similarly, if the wood used in the cabinet is not perfectly dry or has natural imperfections then the panel will warp no matter how it is treated.

Unlike traditional cabinets, Sing Core does not derive it’s strength from lumber, but from our patented core. This core is impervious from warping, is much lighter than a traditional wood cabinet door, and provides better insulation.

Barn doors that won’t warp

If you want a barn door that stays perfectly straight no matter what, you will have extra difficulty if you use a pure wood door. Barn doors only have 2 points of contact per panel, and therefor cannot benefit from mechanical stability of 3 or more points of contact.

Sing Doors, although not the cheapest on the market, can save time and money because you can be confident that our attractive natural wood panels are backed inside with a space age technology.

How to build a barn door that won’t warp

To build barn door that won’t warp:

  1. Order a sing core panel of your chosen length, width, and thickness
  2. Choose your skin thickness and finish
  3. Finish to you choice of color the raw wooden sing panel
  4. Mill out and install hardware

Why do doors warp

Doors warp because of uneven humidity causing dimensional change in the panel. Additionally, imperfections in the wood and stress on the door over time can lead to warpage.

Sing doors combat all these issues with out patented Sing Core material that is stronger than steel by weight and the times lighter than wood. All our “professional” grade panels come with a pure lifetime 50-year structural guarantee. Doors with excessive warpage will be replaced, with only minimal questions asked.
