Extra Wide Door

The extra wide door adds an additional edge and flair to any project, whether it is automatically retractable, articulated by hand, or hidden within a wall pocket. As magnificent as extra wide doors are, there are challenges facing the architects, designers, manufacturers, installers, and end users which are best solved prior to attempting to incorporate an extra wide door in your next project.

Of all the extra wide doors, the wide barn door is the most popular method of handling wide doorways and openings in industrial and commercial applications. The standard configuration of a wide barn door consists of a large wide panel with wheels in tracks in or on the door’s base and suspended from wheels in guides at the top of the door, enabling it to articulate, open and close, by sliding back and forth left to right.

An extra wide barn door presents challenges, the first of which is the extreme weight of the extra wide door. No doubt the door is large, and the common belief is that it makes sense to be made of heavy material because it needs to have structural integrity. Until recently very heavy building materials were thought to have the greatest dimensional stability. That was, until the introduction of patented and patent-pending Sing Core.

Sing Core offers a lightweight solution for building extra wide exterior doors which are far more dimensionally stable than heavier building materials. But weight is not the only challenge faced by those who would like to incorporate an extra wide door into their project.

The problem with extra wide doors is that they are difficult to keep straight over a wide span. They have a tendency to move according to variations in the environment. If sunlight hits the door, the temperature changes. If there are variances in moisture content on either side of the door, and any other number of reasons, that huge door panel will warp, bend, twist, cup, or start to come apart, resulting in utter failure of the door altogether.

Extra wide doors are expensive, but the cost of maintenance on such a door over time far exceeds the initial cost of the wide doorway solution.

That is where the characteristics of inventor Peter Sing’s patented and patent-pending extra wide door core shines brightly. Until the release of Sing Core, there was no way to create a large lightweight panel with the structural integrity to remain warp-free over the life of any extra wide exterior doors.

The unique attributes of Sing’s core imbue any tall and extra wide door with the ability to be incredibly lightweight with superior dimensional stability while being fully insulated for both climate control and sound deadening capabilities. Take a look at the characteristics of Sing’s core,

Lightweight	A fraction of other standard high strength building materials
High Strength	Dimensionally stable, independently tested, stronger than steel lb. for lb.
Fully Insulated	Insulation values are customizable to meet your specification. Start at R3.5.
Soundproof	Patented Sing Core is used by soundproof door companies for sound deadening
Warp-free	Non-warp Sing Core uses patented and patent-pending stiffening technologies

Sing’s groundbreaking technologies empowers manufacturers of extra wide doors to create doors of enormous size which are lightweight and can be guaranteed to remain straight and true over time. In fact, any extra wide door with Sing Core inside can be guaranteed not to warp, bend, twist, or otherwise fail for 50 years.

50 YEAR WARP-FREE GUARANTEE

Doors with Sing Core inside can be guaranteed to remain warp-free for 50 years. Inventor Peter Sing provides his patented core and patent-pending stiffening technologies to the biggest and best door companies, millworks, and custom extra wide door manufacturers.

The biggest door companies in the USA started to exclude large doors from their door schedules due to the constant problems associated with failure in the field. Most of them guarantee their doors for 1 year or more following installation. Since those wide doors failed, they would exclude them from the warranty with a specific rider, or eliminate them from the order altogether, forcing the customer to outsource the large doors to a millwork.

Now that the most powerful door companies in the world have access to Sing’s core, they are back in the extra wide custom door business again.

Large Interior Doors

Masters of oversized doors, Sing Core has been enabling the biggest door manufacturers in the USA to make the best biggest doors that can be made and guaranteed to remain warp-free for 50 years. For 50 years, the major door companies opted out of the large interior door marketplace because the rate of complaint and return was too high, easily eating up year-end profits.

So, the door companies would supply all the standard-sized door while referring the large exterior doors, large pocket door, large interior doors, large glass sliding doors, large garage doors or large wooden doors to a millwork who specializes in one-off specialty doors and let them deal with the service calls.

Then, about 20 years ago the millworks started making doors with Peter Sing’s patented Sing Core inside. Now they could make huge exterior doors and large interior doors, including large wooden doors that would stay straight and true for 50 years, guaranteed. Until the invention of Sing’s core, this was never possible in the large interior door industry.

It took a few years for the standard door manufacturers to come around, but they did. Now you can do to just about any door company and get the entire door schedule for any project including the huge mammoth-sized doors all sourced from one company, plus the entire package could be covered by the manufacturer’s warranty without having to have a rider to exclude the big interior doors or enormous exterior doors.

Sing supplies the warp-free door blanks for each door company’s designer oversized doors which are available in any custom size large doors up to 50 ft. Sing’s interior doors come in a wide variety of styles to accommodate any size or style, allowing architects and designers to freely express themselves in terms of door sizes with unlimited large interior door options.

Floor to ceiling doors are reaching new heights of interior door designs for everything from custom interior to wine cellar doors in contemporary architecture and design projects across the USA. These large luxury interior and exterior doors are available in any flat building material such as wood, steel, and fiberglass exterior, and interior doors, including storm, and patio doors.

No job is too challenging for patented Sing Core. Sing has a specialized True Flat Team which reviews every job that would otherwise be too challenging to consider for any conscious project manager. The team reviews all the data of the fashioned interior door designs and comes up with the best solution(s) to provide a door that is

Lightweight (a fraction of the weight of other solid core doors)

High strength (Sing Core is rated at 600+ PSI, stronger than steel lb. for lb.)

Fully insulated (for sound deadening and climate control)

High precision (Sing’s core +/- .006 in. tolerance)

Warp-free (guaranteed for 50 years)

As many of Sing’s clientele has admitted,

“There is just no other way to do it.”

Sing’s Core doesn’t have too much advantage for use in standard sized doors, though companies who specialize in impact doors, sound proof doors, and high end refrigeration applications do build smaller doors with Sing Core inside.

Where Sing’s core really shines is in doors that start at 48″ x 96″(4′-0″ x 8′-0″) doors and go up from there (to 50 feet?). You probably want to know,

How to buy the best large interior doors for your home

It is easy if you have an architect onboard, your architect simply specifies a door with “Sing Core inside” then the rest of your team just makes it happen. If not, you can contact any of your favorite local door companies or millwork (just Google “millwork near me”) and tell them what you want. Peter Sing and his True Flat Team will use all their resources, patented and patent pending, to create for you the warp-free large interior doors of your dreams.

How can Sing deliver such large doors?

Military and government agencies are able to coordinate transfer of items that are too large for average transport, otherwise Sing designs them as modular big interior doors that can be assembled onsite, with all the precision of being assembled in his factory. This is another piece of the puzzle that Sing has mastered.

So, whether you are looking for the highest quality exterior doors or the widest range of interior door styles then and you desire only the best doors ever made with the best warranty in the United States, then made in the USA premium doors with Sing Core inside are the only doors that will do.

Accept no substitutes. (Don’t get caught trying to switch a regular door with one that has been specified as having Sing Core inside, because when it fails, the customer will contact Peter Sing, and everyone will know that you tried to cut corners… true story.)

Everything from impact resistant slab doors to premium and unique interior doors because every door with Sing Core inside is an individual work of art, which is guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years.

Make sure your handcrafted beautiful custom wood doors and beautiful solid wood interior and exterior doors have Sing Core inside.

Extra Wide Front Door

The inventor of patented Sing Core invites anyone to challenge his claim to fame being,

“The only way to build an extra wide front door that does not warp.”

Peter Sing’s revolutionary lightweight high strength extra wide front door core is what makes it possible for all the biggest and best door companies in the world, millworks, and specialty custom architectural door builders to build extra wide front doors that can be guaranteed not to warp for 50 years.

What?

Peter Sing, the inventor of patented Sing Core and many patent pending anti-warp and composite technologies associated with the creation of extremely large door blanks (up to 50 ft. or more) which are high tolerance (within +/- .006 in.) and dead flat.

Sing’s True Flat Team reviews every extra wide front door spec and assists in the engineering of a door blank that can stay straight and true for 50 years.

Finally, thanks to Sing’s door building technologies, the biggest and best door companies, millworks, and custom door manufacturers are able to build enormous extra wide doors of nearly any material, which would otherwise be highly problematic to use, like solid wood for example, that are Eco-friendly and will not warp.

Large Barn Doors

Eco-friendly large barn doors are taking on a whole new look and are a more sustainable solution for indoor and outdoor applications while commanding a unique stylistic approach to contemporary architectural design. The best extra large barn doors are emerging as featured presentations in all types of structures from residential and commercial to hospitality and industrial venues.

This new approach to the modern barn door is creating a stir as simple design of the traditional wood sliding barn door is now able to incorporate exciting characteristics that far surpass the simplicity of your grandfather’s farmhouse sliding door by incorporating this new generation of large architectural barn doors.

So, what makes this superior modern barn door so different from the sliding farm door of yesteryear?

While they may look similar, the large barn door hardware is much more sophisticated, but the biggest secret of all is what is found deep inside the best large barn doors of all time. If you were to look inside, you would find a patented substrate specifically designed to build the ultimate large barn doors.

For instance, if your modern barn door has Sing Core inside, you will possess a door which is

Eco-friendly
Lightweight
High strength
Solid as a rock
Fully insulated
Warp-free
Guaranteed 50 Years

Large Barn Door Problems

If you were going to make a high-end large barn door for a demanding client or visionary contemporary architect, you would have to hire a door engineer with the ability to design sliding barn doors which could be built to architectural specifications. The goal is to have an end product, a large barn door, which will not warp, fail, or require regular ongoing maintenance to keep it operational over time.

If the large barn door was quite oversized, say anything over three-and-a-half ft. wide and 7 ft. tall, you would find some extreme goings on inside such a door. There would likely be some type of welded steel interior framing and other heavy inserted in an effort to keep such a big barn door from warping, a pretty toxic approach to trying to solve the problems associated with large barn doors.

This is the biggest complaint with failing large barn doors: They warp. And warping barn door, if they are warped enough, will cease to operate, and if they are very heavy, this causes extra stress and strain on both hardware and the structure itself.

Large Pocket Doors

For years, large pocket doors were not being installed in new builds due to problems associated with pocket doors which exceeded the normal range of door sizes. The biggest concern with these big pocket doors was their tendency to twist or cup according to the season.

If you haven’t experienced such challenges, it doesn’t take too much stretch of one’s imagination to entertain how frustrating it would be to open or close your large pocket door only to find it had seized up either inside or outside of its pocket housing.

Pocket doors are a magnificent way to cordon off an area or open up two adjoining spaces quickly and easily, and if your sliding pocket doors operate as expected, it’s an elegant sight to behold as the sliding doors smoothly disappear into their wall cavities. This is why they are sometimes referred to as a hidden pocket door or concealed sliding door. No swinging into the room so as to disrupt the area or require clearance for opening and closing, and not to be seen in the open position, as if they were never there in the first place.

Large pocket doors are coming back into new builds and remodels because he has provided the door industry with the warp-free technology required to create warp-free large pocket doors which can be guaranteed not to warp, bend, twist, cup, or otherwise fail, for 50 years.

Sing Core enables pocket door manufacturers to create large pocket doors of immense size built of any material, measuring up to 50 ft or more, and still be guaranteed to offer fail-free service for 50 years.

Sing Core’s eco-friendly patented and patent-pending warp-free technologies enable his factory to create non-warping substrates which are high precision (+/- .006 in.), fully insulated (R3.5 or R6.5) for sound dampening and climate control, lightweight (1/3 or less the weight of other wood-based solid core large pocket door blanks), high strength (660+ PSI, stronger than steel pound for pound), and backed by an unprecedented 50-year guarantee.

All that reduction in weight and increased strength, precision, and insulation changes the whole dynamics of a sliding door inside wall which would otherwise be problematic, so you don’t have to worry about your pocket sliding door that goes into a wall which may never come out. You can rest assured that your sliding doors into wall cavity will serve your safely, securely, and reliably over their 50-year guaranteed service life.

If you really want to upgrade your efficiency and the impact garnered by operating your precision large pocket doors, install a double pocket door. That’s right, two separate large double sliding pocket doors side by side, each sliding doors into wall cavity respectively independently or in unison. Make them full floor to ceiling large dual pocket doors for full effect.

Using this technology, you won’t have to worry about shelling out the big bucks for heavy duty large pocket door hardware because the hardware rating required to operate your door efficiently is based on the weight of your pocket door. Large pocket doors with Sing’s core inside weigh far less, enabling designers and installer to use less expensive pocket door hardware reducing the overall pocket door price.

Heavy duty pocket door track is unnecessary, as are expensive pocket door rollers, or other heavy-duty hardware or equipment. Sing Core’s lighter in weight large pocket doors are much easier to transport, manhandle, move about the job site, and install resulting in savings in pocket door cost all the way around.

Now you can have a heavy-duty impact resistant large pocket door that is lightweight and high strength without all the added expense and regular maintenance of any other type of heavy duty pocket door.

The Highest Grade MDF in the Industry

Medium-density fibreboard (MDF) is a popular material, especially because it can be precision sanded and remain very smooth which is an excellent surface area to treat, paint, or apply other materials, anything from vinyl and Masonite® to natural wood grain and metals. The upside to this material is wide open, while the downside presents a challenge.

The biggest problem with MDF is that it is not very stable or strong. The phrase we hear commonly is, “we love it, but it warps like…” (add expletive).

Patented Sing Core and our warp-free technologies enable us to provide millworks and artisans with a high end MDF surfaced material which is lightweight, high strength, and extremely dimensionally stable. Now, you, too, can have the highest grade MDF in the industry to use in your most important high precision projects without risk of failure.

This technology moves the smooth surfaced material which can easily be high precision sanded to a whole new level!

That’s why you find this revolutionary newly invented patented and patent pending warp-free technology atop the tallest building in the United States of America.

Now you can have a warp-free large MDF panel which our clients use to apply almost any laminate surface because it is so smooth, and you can even apply natural wood grain, and it can still be guaranteed not to warp, bend, twist or otherwise fail for 50 years.

Sing Core is the secret weapon used by the top millworks, large furniture designers, and the biggest and best door companies, to keep their MDF straight and true.

It is not uncommon to find Sing’s patented MDF-solution inside the most prestigious locations around the world and from beneath the sea (US Navy) to outer space (NASA) and everywhere in between.

In fact, this is the business arena where patented sing Core shines: If you have a problem keeping it straight, inventor Peter Sing’s core and his True Flat Team can provide you with a rock solid hybrid composite core covered heel to toe in MDF which can be guaranteed warp-free for 50 years.

No other Eco-friendly lightweight material can achieve such feats.

SingCore has very little deflection over a 20′ span:

Even though Sing’s patented insulation reinforced vertical grain torsion box core is often compared to honeycomb core materials, it’s plain to see that no other lightweight honeycomb core material can compare.

Whether Sing’s core is used as substrate inside panels, posts, and beams, or as warp-free door core, you will find architects, designers, and engineers empowered by having access to the most revolutionary building material which is changing the way things are made.

That solution is Sing Core MDF, the highest grade MDF in the industry today.

Large Doors

If there are any two words which easily define what Sing Core does, “large doors,” and there is no better large door in the world. Other words which are part of the Sing Core culture are “lightweight,” “high strength,” and “Eco-friendly.”

Why are large doors the main commodity of Sing Core?

Because oversized doors, if they are over seven feet tall and/or three and a half feet wide present a number of problems inherit to the limitations of available door building materials, most importantly if you are attempting to build large wooden doors.

Large oversized doors will move according to changes in the environment. This is the nature of natural wood grain, which as beautiful as it can be, will move or warp. Warping large doors is the number one reason the world’s biggest door manufacturers seek to engineer and specify Sing Core inside their large doors.

Large Exterior Doors

Large exterior doors (or just plain old exterior doors for that matter) are more prone to warp than interior doors because one side faces a temperature controlled (to some degree) environment, while the other side can be 100% exposed to the weather. This is the perfect recipe for ending up with warping large doors.

These large residential doors can include large feature doors, modern front doors, large pivot doors, and steel front doors, which are among the top few large door requests which are encountered by Sing Core every day.

People do not want to compromise with the primal focal point of their home. The front door is the first point of engagement when someone approaches your home, and for some, making an impact with visiting guests is important to those who are specifying “Sing Core inside,” their doors.

Among other styles of big doors are patio doors, also often big doors which, like large front doors, are subject to warp due to changes according to surrounding elements.

Large Wooden Commercial Doors

Then there are large wooden commercial doors which are problematic when bridging the gap between the creative genius of the contemporary architect and designer on one side and the abilities to create and install such a door by the door manufacturer and contractor on the other.

Frequently we are seeing large sliding glass doors appear more often in drawing boards which feature a wood frame, not unlike large French doors that host a large glass cut out for viewing the expansive outdoors. We are building these large sliding panel doors with big glass cutouts for all kinds of commercial door applications both in interiors and exteriors.

It is not uncommon for us to see large commercial doors, wither with glass or just solid wood surfaces, which span large openings or for separating one or more large open areas, thereby subdividing a large room into several smaller rooms until the large wooden commercial doors are fully opened to expose the entire area of the expanse.

Large Industrial Doors

Large industrial doors can come in any size and covered with any exterior surface material based on the design recommendations of the architects and engineers working on the project. If the project includes a very large door, the True Flat Team works in concert with engineers and architects to produce an Eco-friendly door which is high precision (Sing Core sports +/- .006 tolerances) can be lightweight, stronger than steel, and guaranteed not to warp, bend, twist, or otherwise fail for 50 years.

50 Year Warp-free Guarantee

You read that right. Inventor and CEO Peter Sing is so confident about his patented and patent-pending counter-warp materials that he stakes his reputation on it.

His insulated reinforced torsion box hybrid core is so rigid, he says anything built with it will last for centuries, but he guarantees it for 50 years.

Gone are the days when inexpensive products fill our landfills and contaminate the environment. As more and more products are built with Sing Core inside, they could virtually last forever, and individual components could be repurposed into something new.

So whether you are in search of large pocket doors, large sliding closet doors, a large garage door, or large hangar door, you and your clientele would be best served by making certain your large doors are specified with Sing Core inside, especially for your large, expansive doors and window projects.

16′ Tall Doors in Partnership with Miller Blaker

SingCore is very proud of the work that our clients, and partners in the “Platinum Club,” are able to accomplish. Together we are working to push the limits of what is possible in the realm of custom, large, architectural doors.

In particular, we are pleased to present the work of our friends over at Miller Blaker and their success on the 14′ tall oak doors installed in the One World Trade Center in New York. The crown jewel of American industry, it is an honor for SingCore to take even a small part in the resurrection of this iconic building.

Top of the One World Trade Center

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.

Features of the 14′ Tall Oak Doors

The most outstanding feature of these doors is the extreme size. Many door manufacturers will not even consider building a door at this size, because of the myriad difficulties. Without an advanced technology such as SingCore, a 14′ wood door would be extremely heavy and have the potential to warp over time.

These White Oak doors weight in at a slight 220 pounds each, around a third the weight of a similar door made without SingCore inside. Our patented and patent pending proprietary construction process allowed these doors to be not only extremely light, but also extremely straight. We guarantee all our “professional” grade doors last for 50-years.

Not only functional, these amazing door panels have the look and feel of solid wood. Our “green” technology means that we reduce overall resource usage and primarily use renewable resources such as wood for the construction of our panels.

Technical Features of the Millar Blaker Doors

Like all our doors, these panels were custom designed and manufactured by SingCore to meet client specifications. The design we came up with, and offer to all our clients, includes the following revolutionary features:

Integrated solid wood edging
Sound deadening
Internal aluminum support structs
Custom solid wood blocking for hardware

: Perfect Sides

: Perfect Oak Edges

A Note About Success

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.
