Pocket Door

Pocket doors have become an integral part of modern architectural design.  Despite the many advantages of pocket doors, they do present unique challenges in both the manufacturing and the installation process.

The Best Pocket Doors

Sing Core has become known for making some of the largest, most impressive sliding doors on the market.  Pocket doors are sliding doors that slide into a pocket in the wall.  Certain customers have come to know Sing Core, not only for our sliding doors, but also for our magnificent pocket doors.  Introducing the best pocket doors!

Pocket Door Challenges

The concept of pocket doors seems simple very simple.  They are similar to sliding doors in that they slide on tracks and typically use rollers to open and close.  The big difference is that they slide into a pocket that has fixed dimensions inside the wall.  If the door warps or skews, the door cease to function.  You will not be able to open or close the door because warping will change the dimensions of the door.

Warp Free Pocket Door

Over decades, we have developed our patented and patent pending materials that allow for super strong, light weight, warp free door construction.  Warping and skewing present significant problems for pocket doors, because pocket doors must slide into a fixed space inside the wall.  Any deviation from specifications will prevent the door from fitting into the space.  When this happens, your door will cease to function.  You will need to buy a new door, change out your hardware that may bend or break as a result of door malfunction.  In some cases, you also need to rebuild your door frame or your walls when they are ruined from doors being opened and closed.

But we have solved all of the problems associated with large pocket doors and large sliding doors.  When you use Sing Core products, you not only get a door that exceeds AWI standards in terms of warpage, you also get a door that’s guaranteed against warping for 50 years.  Because of our special design methods, you will get a door that ensures proper functionality for decades.

Large Pocket Doors

The larger the door the bigger the challenge.  Large pocket doors are more susceptible to warping.  In order to function properly, they must be specially designed to resist warping.  Larger doors must be specially constructed so that they are warp free on installation, as well as, over time.

 

 

 

Ultra High Strength – Large pocket door must be exceptionally strong to stand up to the most rigorous use.  At Sing Core, we have revolutionized door strength with Peter Sing’s patented and patent pending technology that allows us to build doors that are very high strength, tested independently at over 660 PSI.

 

Super Light Weight – Up to 90% lighter than solid wood doors.  Sing Core specially engineered core uses Peter Sing’s revolutionary design to bring a solid door strength to doors that allows for super light weight performance.

 

Straight/Warp Free – Specially designed stiffeners built into our doors make sure your doors are warp free over the long haul for better performance and function.

 

Structurally Stable – With our groundbreaking process, we can make doors that are built exactly to your specifications, and will not skew of shift over time.  That way, you have a door that functions worry free for decades.

 

Eco-friendly – We support sustainability by using 100% renewable, eco-friendly materials, so our products are better on the environment.

 

Guaranteed – When it comes to guarantees, no company on the market can do better.  Our Sing Core Professional Panels are used for doors and other high end applications where stability and precision are of the utmost importance.  All of our Sing Core Professional panels come with a whopping 50 Year Guarantee against warping, cracking, breaking, and skewing.  Name one other company who can do this.  Most companies don’t even offer a one year guarantee, but we can do this because our products have such a strong track record of performance.

 

No one can make panels as large, yet warp free like we can!  You have our guarantee on that.

 

Proudly Made in America

All of our products are 100% made in the USA.  We take pride in supporting our country.  That’s why you won’t find any products that aren’t made in America here.  We also use high quality inputs that are sourced from local suppliers.

Door Skins

Our door system allow you to specify almost any skin for your doors.  We specialize in high quality wood and metal doors.  We have several options depending on your budget.  Our paint grade ply option is our most economical option.  Next is our hardwood veneer option.  Mahogany, oak, walnut, and alder are popular.  We also use 1/8″ wood stave on our highest end option, which gives you a solid wood appearance, but has our specially engineered core to maintain the light weight feature our doors are famous for.  We also make metal doors.  In our metal doors category, we specialize in hot rolled and cold rolled steel, but we also have a very popular aluminum option.

Wholesale Large Door Alternatives for the Best Door Manufacturers

The best door distributers represent the best in trusted door manufacturers across America for high confidence and superior door manufacturing ethics which translate to high quality and performance standards for upholding your credibility and professional ability to deliver only the best doors for your clientele.

What About Large Doors?

If you are like other distributors of the top selling doors from companies like VT Industries, you are getting some of the most coveted door jobs in your area of expertise. That is, for everything within the standard door size-range. Large doors are another thing altogether.

Large Doors

Large doors in your door schedule are going to be a problem. First off, your regular door supplier does not carry them, doesn’t want to build them, and doesn’t want you to sell them.

Why?

Because large doors fail. Even in the best of circumstances, with all the talent and expertise in making and installing millions of standard-sized doors, your supplier is unable to provide you with a door that will not fail after installation if its dimensions exceed 4×8.

Any door over 4×8 is going to present your valued client with problems. This is why large oversized doors are excluded from your standard warranty which covers the rest of the door schedule, because everyone knows that a large door will warp if it is over 4×8.

Where Does Your Door Supplier Go for Large Doors?

Every once and a while your door manufacturer takes on a large door job, which may include hundreds of standard-sized doors and a few large pivot doors, large sliding doors, or large hinge doors. What then? They don’t want to lose the job due to only a few large doors.  

So, what do they do?

The biggest and best door manufacturers in the world know there is only one trusted door manufacturer in the world that can make a large door that will not warp, bend, twist, cup, or otherwise fail, and that is Sing Core.

Sing Core Warp-free Large Oversized Doors

Enter Sing Core, the only large architectural door manufacturer in the United States who can build a large oversized door of any type or style that can build a large door of any material specified by your architect that can be lightweight, high strength, fully insulated, and can be guaranteed warp-free, not to fail, including a full structure warranty for fifty years.

Made in the USA

Sing Core doors are sustainable Eco-friendly doors which are proudly made by hand using safe domestic materials via our patented manufacturing methods using less energy, with very little waste, and a highly honorable respect for managing the best of nature’s materials and recycled materials for long almost service-free long life now and for generations to come.

Sing Core Door Characteristics

Besides being lightweight, warp-free, and stronger than steel pound for pound, Sing Core Eco-friendly doors bring many other high-end attributes to the end product which will be enjoyed by your clientele for years to come, adding even more value to your Sing Core door.

Some of the advantages of having a Sing Core door include being fully insulated for climate control and sound deadening qualities thanks to the high-precision (+/- .006 in. tolerance) patented and patent pending composite reinforced door core.

We Don’t Make Doors

Even though the best doors in the world are made with Sing Core inside, we don’t actually make doors at all. What we build is the best non-warping insulated door blanks in the world. We work hand-in-hand with the best door manufacturers in the world to provide your clients with the best doors in the world of any size, even huge mammoth-sized doors.

In this arrangement, as we help support the best door builders, we provide them with the non-warping substrate (what we do best) as we trust them with handling the door finishing, hardware, and installation (what they do best).

What We Can Do

We do provide your biggest and best door manufacturers with the best support system and can provide them with door blanks in various stages of readiness for them to complete in their door factories.

We are often called upon to make bulk runs of standard door blanks quickly, provide door builders with ready-to-finish door blanks prepared by attaching any available flat building materials, such as any species of natural wood grain veneer, natural wood planks, aluminum, cold rolled steel, concrete, fiberglass, FRP, galvanized steel, hot rolled steel, HPL, LVL, MDF, MDO, plywood, stainless steel, just to name a few, ready for your favorite door manufacturer or millwork to finish.

What We Can Do for You

If you have a good local custom door manufacturer or millwork that you work with locally you can order your Sing Core door blanks and have them sent directly to your favorite millwork or custom door maker for finishing, installation of hardware, and installation.

WOOD VENEER DOORS

The top doors in America are installed in the top floor of the tallest building in the United States, located at One World Trade Center, New York. These 16 ft tall 3 ft wide 2.25-inch thick warp-free door panels are among the only Eco-friendly lightweight, high strength, insulated doors made in the USA that can be guaranteed not to warp, bend, twist, cup or otherwise fail for 50 years.

Top floor of One World Trade Center has "Sing Core inside."

Top floor of One World Trade Center has “Sing Core inside.”

If you’re one of the top contractors in America, when you’re called on to deliver the best tall doors to the top of the World Trade Center, you want to make sure you’re not embarrassed when your sleek white oak doors fail due to warping.

When your reputation depends on it, you need the backing of a professional company that can deliver the goods and have your back, and there’s only one company in the United States that builds large doors which can be guaranteed for 50 years.

The most exclusive architects in the world specify “Sing Core inside” their doors when nothing less than the very best will do, and you want your customer to be on the top of the world.

Let’s take a tour of these revolutionary doors from the factory to the top floor of World Trade Center One…

Photos taken from the edge of the panel show the perfectly straight quality. The panel shows glue on the edge, because the customer requested untrimmed ends.

Measuring at 2.25 inches thick, this is the most premium quality door money can buy.  Due to the patented and patent pending SingCore technology, this 15.5 foot long, 3 foot wide, 2.25 inch thick pivot door is straight as an arrow, better than AWI standards.

Many Ways to Build It

Depending on your budget, you have a number of different options when you opt to go with Sing Core.

  • You can order substrate only and apply your own soft wood or hard wood veneer (economy option)*
  • You can supply your own veneer for us to apply
  • You can choose solid wood edge banding
  • You can choose our highest end selection, where we provide the veneer and apply it in nearly any soft wood or hard wood, such as, Mahogany, Walnut, Maple, White Oak, Alder, Cedar, Hemlock, Fir.

How to Build the Perfect 16 ft. x 3 ft. High Precision Warp-free White Oak Door

You start with patented and patent-pending Sing Core inside sandwiched between American-made A/B plywood with solid oak around all four edges.

After pressing, trim the edges, then add another 1” x 2.25” solid oak to the edges. Sand it to perfection then hot-press 16th-inch white oak veneer, then all you can see is solid white oak. Beautiful.

The result is a perfectly flat lightweight white oak door that is stronger than steel pound-for-pound, weighing in at a mere 220 lbs.

 * Professional veneering can be very tricky. If you are getting substrate from Sing Core and having your millwork (or someone else) apply the veneer, be certain to affirm that they have the expertise to apply the veneer appropriately. We use the highest level of professional veneer professional and techniques. We can guarantee our veneering, if you have veneering done off-site, it is their responsibility to do it correctly. A faulty veneer could jeopardize your Sing warranty.

Ask us if you have any questions.

Full Service Veneering:

We offer our ultra high quality veneering service for customers who need that extra level of quality.  

The process of applying veneer isn’t simple.  One wrong move can ruin your product, which means large amounts of money fixing the problems.  It can even result in the need to buy new doors. We have solved all of these problems for you, but your choice of methods will ultimately depend on your budget.

 

If you decide to veneer your own doors, we offer more than one option:

Premium Option

MDF layer.  We apply an MDF layer to our legendary ply substrate.  This offers you the most stable option for applying your veneer job.  You can save money on your end by getting the job done correctly the first time.  Besides, if your do not apply your veneer to the proper surface, it could result in having to redo your veneer job.  In the worst case scenario, applying your veneer improperly can ruin the doors.  That’s why, with our premium option, we ensure you a proper surface for your application.

Standard

Our standard substrate, made from high quality plywood, offers you a great surface to apply your skins, but you must make sure to do your veneer job properly, or it could result in a ruined veneer job.  Veneering requires experts who have a very high level of skill.

Note: SingCore is not responsible for any damages which result from skins improperly applied by our customers.

Sing Stile and Rail Doors

The Sing-style approach to stile and rail doors is a horse of a different color amidst the age-old door industry. Sing stile and rail doors are lighter in weight and stronger than steel yet made of nearly any flat building material available, not matter how they’re built.

Sing Stile and Rail Look

Our most sought-after stile and rail manufacturing method produces a stile-and-rail-looking door from a solid composite Sing door slab which feature alternating wood grain orientations on the door surface to emulate the look and feel of a stile and rail door without any weak spots.

The resulting Sing Stile and rail door made of a solid door panel is the strongest, lightweight, most insulated, Eco-friendly door proudly made in the USA.

Sing Stile and Rail Construction

Even among the most tried and true stile and rail door manufacturers, they know that the only way to build a large stile and rail door which can be guaranteed not to warp for 50 years, is with Sing Core inside.

Rather than build a stile and rail looking surface and applying it to a solid slab of Sing Core, traditional stile and rail manufacturers prefer to use stile and rail components with Sing Core inside.

Basically, this means that all the stile and rail components are manufactured by Sing Core in building material formats which are very similar to our post and beam configurations, and/or furniture panels. These are assembled by your favorite stile and rail door builder just as they would any traditional wood stile and rail door components.

Sing Stile and Rail Advancements

You might be surprised what benefits can be enjoyed by custom door makers who construct their doors using patented Sing products. This new, revolutionary door building material is

Lightweight Stile and Rail Doors

Weighing in at a fraction of other solid core doors, Sing stile and rail doors can be very lightweight, even if they are very big doors, without threatening the longevity of the door’s performance over time.

High Strength Stile and Rail Doors

Stile and rail doors made of Sing Core are incredibly strong. Rated at 660 PSI, Sing Core is stronger than steel pound for pound, thanks to Peter Sing’s patented solid composite torsion box core substrate, incredible unsupported spans are possible, enabling doors with Sing Core inside to outperform any other lightweight door.

50 Year Stile and Rail Guarantee

Professional grade Sing Core has such a high precision tolerance (+/- .006 in.) and withstands just about any variance in conditions across the board, that these are the only door which can be guaranteed not to warp, bend, twist, or otherwise fail for 50 years, including full structure warranty.

Eco-friendly Sing Core

Using Sing Core is the Eco-friendliest way to build a sustainable door, which is made with a smart combination of minimal natural and recycled material combined to create this revolutionary door core material which is the lightest weight and highest strength way to build doors of any kind.

New Revolutionary Door Technology by Sing Core

We offer our services to support door manufacturers in building stronger, lightweight, high precision and warp-free (AWI warp standard) insulated doors using our patented and patent pending Sing Door Blanks and Sing Stile and Rail frames.

Sing Core’s specialty is assisting to create incredibly large and extremely wide door panels which door manufacturers can utilize to build the most challenging high-end doors.

Large Quantity Production Runs

We can also assist in the high-quantity production runs for doors using our facility to pre-build base doors which might otherwise create a bottleneck for common door manufacturers. We love taking over the assembly line bulk of your large door orders with rapid turnaround times.

You choose your method of building your Sing Core door blanks:

1. Sing Door Core Panel

You specify the length, the width, and thickness of your Sing door blank, built to your specifications. You determine the insulation value and skin material, and we do the rest. The Sing door core panel method is the strongest and best Eco-friendly insulated door solution for any sized door, even large oversized wooden doors, available in almost any style.

2. Stile and Rail Door Frame

For our customers and their clients who prefer the standard design of stile and rail doors, we provide the manufacture of a stile and rail formatted frame made of any combination of Sing panel, post and beam configurations to create the most sustainable stile and rail doors, which are finished by only the best millworks and custom door manufacturers. Sing Core provides the most significant improvement to stile and rail technology (besides automation) in the last 100 years to create the strongest, lightweight, most high-precision, and warp-free performance in the history of the door industry.

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.

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.

Door Sizes

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.

Door Shapes

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.

Skin Options

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.

Light Openings

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.

And that’s just scratching the surface…
