High End Pivot Doors

Sing Core goes through great lengths to provide the best architects and millworks with the best high-end pivot doors in the world. High end pivot doors stand out because they are generally massive in size which can be problematic for engineering a door which performs flawlessly over time.

Unlike hinged doors, your pivot door rotates on a pivot box, which only has two anchor points, whereas a hinged doors has three anchor points on one side of the door which helps to keep the door straight.

Sing Core assures clientele that they possess a high-quality pivot door that can be guaranteed not to warp, ben, twist, or otherwise fail for 50 years. Astonishingly, Sing Core can design huge wood pivot-hung entry doors that can also be guaranteed not to warp. (Something unheard of in the door industry until the invention of Sing Core.)

Inventor Peter Sing’s patented high-end pivot door core makes all the difference. Sing’s factory is not a door manufacturer, instead his factory provides the best door manufacturers, millworks, and custom pivot door builders with the base material which makes the highest standard of large pivot-hung entryways possible.

Exquisite cooperation in design and quality construction while working with a team of architects, door designers, engineers, manufacturers, finishers, and installers assures that Sing’s Eco-friendly high-end pivot doors possess the following attributes:

Lightweight

High Strength

Fully Insulated

50-year Warp-free Guarantee

Sing’s pivot doors weigh so little that millworks and door manufacturers are amazed that two people can easily maneuver a 20 ft wide pivot door blank. It is something you can’t quite understand until you are actually holding it in your hands.

These patented Sing cores are so strong, you can see Peter Sing standing on this 13 ft long one-inch thick panel with little or no deflection. Imagine what you could do with Sing’s core.

The pre-installed rigid insulation offers added safety and security, sound deadening, and increased climate control.

And what you get in the end is a pivot door that is prefinished with high-end craftsmanship that looks like a huge solid wood pivot door, and only you will know that it has Sing’s secret pivot door core inside.

This is how the highest quality pivot front doors are made.

Generally, large pivot doors are quite thick, which leaves anyone who encounters such a door with a striking first impression, which is imprinted in nearly everyone’s brain, and they will be found later telling stories about the enormous pivot door that articulated with such ease. Even so, Sing’s core is so lightweight and strong that you can create a high-end ultra-thin pivot door, if necessary.

The Sing Core pivot factory can also preconfigure your high-end pivot door with any type or style of custom lite opening. You can feature several lite openings for a particular design effect, or one large opening for that French door feeling that maximizes pivot door views of the outdoors and/or neighboring landscapes.

Peter Sing’s philosophy is one of simple beauty and lasting quality with an unparalleled guarantee which cannot be achieved with any other lightweight pivot door core, until now, thanks to his invention.

While most of Sing’s pivot doors are designed and built of wood, many are built of metals, such as aluminum, steel, and other types of metals including bronze pivot doors, and could be made of nearly any flat building material.

If you want the best high-end door with the best guarantee, maybe you should think about talking to your architect about having Sing Core inside your pivot door.

High-end Veneer Doors

Sing Core specializes in increasing the performance, durability, and customer satisfaction in high-end veneer work in custom veneer doors of any size which can be guaranteed to remain warp-free for 50 years, including full structure warranty. No other method of manufacturing a large high-performance veneer door can achieve these results.

It all starts deep within the structure of any veneer door with Sing Core inside. Sing Core is the patented brainchild of inventor Peter Sing who conceived of the structure core which revolutionized the way doors were made.

Sing’s invention is basically a vertical grain torsion box core with small grid structure where the grid voids, which are usually left open in traditional torsion box, are filled with rigid foam insulation.

This composite base material is pressed between to stress skins to create Sing’s lightweight high strength high-end veneer door core.

The biggest and best door companies, millworks, and custom door manufacturers love it, and you will find them using Sing Core inside all their high-end custom large veneer doors. And that’s why you’ll find them at the top of the tallest building in the United States of America, World Trade Center 1‘s Freedom Tower.

16' Tall Oak Doors in One World Trade Center

Telegraphing and Crossbanding

The most environmentally conscious way to create a veneer door is with a thin veneer material, such as 0.020-inch veneer. The only problem with this thin veneer is telegraphing.

It is normal to crossband veneer, which basically doubles the price of the veneer, to prevent telegraphing.

Not necessary with Sing’s super-smooth veneer door blanks. He uses his patented veneer door technology to create an extremely smooth surface to lay veneer on flawlessly by using a thin later of MDF to accommodate the lamination of a thin veneer.

Problem solved.

Large Oversized Veneer Doors

When architects spec an architectural veneer door, if it is a very large door (anything over 8 ft tall or 4 ft wide) they are far better off going with a thin wood stave surface. Wood stave consists of wood planks cut into thicknesses of 1/8 to 1/4 -inch thickness. Then this solid wood is applied to Sing’s door blanks.

Veneer is normally limited in available lengths, whereas planks of specific wood species are generally available in longer lengths. This can accommodate the long length necessary for a vertical grain veneer door design.

Plus, if it’s done right, your high-precision large wood stave door with Sing’s core inside looks just like a solid wood door. Only it weighs far less than any other solid core door, and can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years.

And no other door can come backed with such an impressive guarantee.

Even though Sing’s doors are desired by nearly everyone, to have such a door may be cost-prohibitive for most. It is more common to find high-end veneer doors with Sing Core inside in the most expensive homes in the USA. You may find them used in scientific research, and anywhere in the world, from beneath the sea (US Navy) to outer space (NASA) and anywhere in between.

Once you’ve experienced a high-end veneer door of such magnitude, you will agree with the professionals who insist on using Sing’s patented solutions, that,

“It’s the only way to do it.”

Sing Core is the only way to build a big veneer door that can be guaranteed for 50 years. The only way.

Interior Sliding Barn Doors

It is not uncommon for interior sliding barn doors to be specified as metal barn doors, such as steel sliding barn doors and aluminum interior barn doors.

Natural wood species top the requests for interior sliding barn doors, by far. While contemporary architectural design fashion shifts dramatically, the most common natural wood grains specified for natural wood architectural doors are:

Top 10 Wood Interior Sliding Barn Doors

1. Pine Barn Door

2. Cedar Barn Door

3. Walnut Barn Door

4. Knotty Pine Barn Door

5. White Oak Barn Door

6. Alder Barn Door

7. Maple Barn Door

8. Hickory Barn Door

9. Mahogany Barn Door

10. Cherry Barn Door

And just in case you were wondering these other natural wood interior sliding barn doors follow the Top 10 in their order of popularity: Red oak, red cedar, teak, birch, ash, white pine, fir, hemlock, beech, and rosewood wood species.

Even though these natural wood species are the most popular, doesn’t mean you are limited by any means. The more high-end the project is, whether it is an exclusive commercial or residential structure, the doors could be specified as very exotic wood.

By using veneer doors as your interior sliding barn doors, you honor and preserve the natural resources by using very thin layers of the natural wood on the surface, which can end up looking like a solid wood door, if you do it right.

Natural wood veneered interior sliding barn doors are a conscious use of natural materials, whereas natural wood veneer may not be recommended for exterior doors. Wood veneer is too thin to be used in an exterior application, as it cannot take much abuse when exposed to the elements. In the case of exterior doors, it is best to stick with wood stave doors, using natural wood planks of at least 1/8” thick.

The Best Interior Sliding Barn Doors

The best interior sliding doors have Sing Core inside. You might ask, “What is Sing Core?” Sing Core is a patented core material invented by inventor, Peter Sing, who is also the president of Sing Core. His experience and fascination with aeronautics led him to create a lightweight high strength building material which could be used in the aerospace industry.

Who knew he would invent the most exclusive sliding barn door substrate material that could be used to build enormous interior sliding barn doors up to 50 ft. that weight a fraction of the weight of other wood-based solid core doors and are stronger than steel pound of pound (independently rated at 660+ PSI).

But Sing’s invention doesn’t stop there, Sing also pre-insulates every one of his door blanks to further enhance its features, such as increased climate control and built-in sound proofing for increased energy savings, safety, and security.

And on top of that, there is the unheard of guarantee that cannot be touched by any other method of building doors, with Sing’s own,

50-year Warp-Free Guarantee

Sing’s invention has enabled the biggest and best door manufacturers in the United States to build these large oversized sliding barn doors that can be guaranteed not to warp, bend, twist, cup, or otherwise fail (including structure and lamination) for 50 years, for flawless customer satisfaction.

Proudly manufactured with locally sourced materials and made in the USA by highly skilled craftspeople and artisans, the art of building customized warp-free substrates which are perfectly matched for any surface material and it’s inherit reaction to changes in the environment and tendency to move.

As Sing’s clients have been saying for more than 20 years, now,

“There’s no other way to do it.”

There is no other way to build a large door of any type or style and guarantee that it will basically never warp, guaranteed.

Mr. Sing says, “I could not say it, if it wasn’t true. And If it wasn’t true, if even one door warped, I’d be out of business.”

Sing Core is the only way to build a warp-free interior sliding barn door, period.

Veneer Door

Veneer doors are the most responsible use of natural resources because the declining supply of available natural wood grains are mediated by slicing very thin layers of grain into sheets of natural material which can be applied to a flat surface, such as plywood, panels, or used as door skins.

Most Popular Veneer Doors

While the various wood grain varieties of doors change, some veneer types are more popular than others around the USA. Right now, the two most popular wood veneer doors are,

Walnut Veneer Doors       and       Oak Veneer Doors

Walnut and oak veneers are tied for first place in the world of veneer doors, followed by maple, birch, teak, mahogany, cherry, ash, cedar, and pine veneer doors, in that order.

A veneer door is indeed beautiful, but this elegance is only skin deep. The attributes of the veneer door’s underlayment are the key which greatly enhances or diminishes the appeal of your veneer door, which is the best predictor of your veneer door’s performance over time.

Veneer is an excellent way to build a standard-sized door, but when you are reaching for door heights which pass the 8 foot mark or widths that are greater than three-and-a-half feet wide, you start running into the risk of door failure.

Even if you run into a problem with a standard sized door, it’s not too much of a problem, because factories (most offshore) are churning these out by the thousands every day. So, when your door fails, you just run down to your local hardware store and buy an inexpensive replacement door and you are back in business. This is often less expensive than hiring a millwork to service or repair your veneer door.

Large Veneer Door

Large veneer doors are an entirely different animal. These oversized doors do not come off of a conveyor belt. They are usually a one-off build by a highly skilled artisan or team of craftsmen who are building these big veneered doors according to engineered architectural specifications.

There are many things to take into consideration for a large door with a natural wood veneer on it. The first consideration is the veneer, itself. How thick is it? What will the substrate be made of? How will it be applied to the substrate. If, laminated, what is the method used, what adhesive will be applied, and how long will the lamination last, before it starts to delaminate?

Wood veneered doors are more commonly used indoors, as the thin veneer is not well-suited for exposure to the elements, such as in a large front door application. In this case, you would be better off using a thicker surface material such as an eighth to a quarter inch-thick wood stave skin (planks) for exterior doors.

Most importantly, you want to pay close attention to how the door will be made from the inside out, especially in large veneer doors over a standard 3-0 7-0 door? Why? Because they will warp. Almost any material used in building an oversized veneer door will move according to variations in the environment where the door resides.

I say, “almost,” because there is one way to build a large veneer door that will not warp.

Warp-free Veneer Door

If there’s one thing that the high-end custom veneer door manufacturers know, it’s that if it’s large and, “If it doesn’t have Sing Core inside, there’s no warranty.” Why? Because all large veneer doors move. That is to say, they warp, bend, twist, or delaminate, because they do not have Sing Core inside. All due to the movement of the door over time which breaks down all the necessary components and compromises the operation of the door.

Thanks to inventor Peter Sing’s invention of his engineered composite hybrid warp-free veneer door core, doors can be made to remain straight and true for years to come. They are also the lightest weight strongest (stronger than steel pound for pound) door blanks in the world which are also fully insulated for added sound deadening and climate control capabilities.

Even though Sing says, “We do not build doors,” he is responsible for some of the biggest most beautiful doors in the world that deliver the highest precision (Sing’s core boasts +/- .006-in. tolerances) most sustainable doors in the world with unsurpassed longevity. Each door with Sing’s core inside can be backed by Sing’s unprecedented,

50-Year Warp-Free Guarantee

This is the truth. Sing guarantees his doors to remain warp-free for 50 years. He has been providing the biggest and best door companies in the nation with warp-free door core. And if you ask these door companies, “Why?” They answer,

“There’s no other way to do it.”

There is no other way to build a big veneer door that will not warp without Sing’s core. That’s why we rely on Peter Sing’s invention to deliver the goods. And, as Sing says, “If it wasn’t true. If I couldn’t do it, even once, I could never offer that guarantee again.” And he’s still here without even one warped door in ten years.

How do you get Sing Core?

Increasingly, Architects are specifying Sing Core in all their high end essential large door projects. But if you want one, all you have to do is to go to your local millwork or large custom door manufacturer, and tell them what you want, but be sure to tell them, “I want Sing Core inside,” and leave the rest up to us.

It takes a village to build a large veneered door.

Architects and engineer’s work on the concept and the design, then there are the door companies and millworks who are responsible for the hardware and finishing aesthetics, and finally fine craftsmen hang and install the door.

Your veneer door with Sing Core inside is a one of a kind work of art.

That’s why you find Sing’s core in the tallest doors in the tallest building, on the top floor of the Freedom Tower at World Trade Center in New York, and anywhere from beneath the sea (US Navy) to outer space (NASA).

Let us help bring your dream door to life.

Sliding Interior Doors

Interior sliding doors have come a long way, and now you have so many choices available in the most modern sliding door ideas that anyone could have the most stunning side-sliding entry point. From the sliding barn door to the sliding pocket doors, these space-saving sliding interior doors are among the best sliding doors in the world.

The best exterior and interior sliding doors made in the United States of America all have patented Sing Core inside and are guaranteed to remain warp-free for 50 years, including a full structure warranty, and this is not to be found in any other interior sliding doors.

Sliding interior doors may not sound like a complicated job when it comes to including architectural details or incorporating large sliding doors in your designs, but if you’ve had your feet in the clay for some time, you should be aware of the problems which may be presented by internal sliding doors, especially if they are large in size.

First off, the most desirable material for sliding interior doors is any number of natural wood species. Wood sliding interior doors can be a challenge, if not at the outset, then definitely over time. Why? Because wood moves. It may no longer be a part of a tree, but it still responds to changes in the environment, which causes your sliding interior doors to warp.

Thanks to inventor Peter Sing and his inventions at Sing Core, door manufacturers (some of the largest and most prestigious door companies in the world) can create warp-free indoor sliding doors that can be guaranteed to remain straight and true for 50 years.

How to Make Warp-free Sliding Interior Doors

Sing’s patented and patent-pending warp-free wooden door technologies are based on a basic well-known wood crafting technique called torsion box, which is a respected technique for building things out of wood that will resist warping as well as reducing the overall weight of large wooden items such as conference tables and internal wooden sliding doors.

Though Sing’s invention does stop there, his warp-free-door technology goes so much further beyond standard wood working techniques. For instance, he started out by reorienting the direction of the torsion box frame from horizontal to vertical. That, in itself, was a huge improvement for warp resistance and increasing shear strength. But he didn’t stop there, either.

Next, he filled all the individual rectangles (hollow spaces left open in traditional torsion box designs) with rigid foam and secured these metric components between two stress skins using formaldehyde-free glue in the most Eco-friendly manner for the most sustainable substrate known for use in sliding interior doors.

Sing unveiled his truly modern barn door, and the biggest and best door companies, were all over it. Prior to Sing’s invention, the big door companies had all but eliminated the production of oversized doors of any kind due to their propensity to warp, making them impossible to warranty, and repeated service calls made them impractical to offer. If they did take on one or two large sliding interior doors, they would add a rider to the contract indemnifying them from any responsibility due to warp.

Keep in mind that even though the best sliding interior doors have Sing’s core inside, his company does not actually build doors, even though Sing is well known for making some of the most perfect doors, he only supplies the raw product, the door blanks or sliding door core, to the door companies, millworks, and high end custom door manufacturers, who actually create the masterpieces on his canvases for which he is so well known.

They are in the process of expanding their large custom sliding interior door divisions because they can confidently deliver a high precision, high-end solution which includes Sing’s 50 year structure and non-warping guarantees.

So, now you can get large sliding interior doors that are lightweight, insulated, stronger than steel, and made in the USA that are guaranteed not to warp for 50 years. All you must do is to contact your local door provider, and tell them you want, “Sing Core inside.”

The Biggest Door Secret in the USA

The most highly regarded secret of the largest door manufacturers in the United States is that their most high-end doors have Sing Core inside.

 

These are among the most profitable privately held companies in the country, and there was a time when they avoided taking on the hard jobs; those jobs that included large doors over 7 ft tall. Why? Because of customer complaints and returns. They were better off excluding that part of the job, and let the individual millworks fight over trying to deliver those big doors.

Then, the millwork that won the job would have to deal with the complaints of having to replace or continually service large oversized doors that were bound to warp and fail periodically over the life of the door.

That is, until these dominant door manufactures learned the true secret; that Sing Core empowers them to create the high-end doors which allowed them to expand and evolve into even more profitable door companies in the USA.

Why?

Because they could now provide the largest and most unique door creations with the highest precision (+/- .006-in) and the best guarantee, bar none, thanks to inventor Peter Sing’s patented and patent pending large door building technologies.

50-Year Guarantee

Whether they pass the guarantee onto their end users or not (as their company policy might be only to provide a 1-year guarantee, if any at all, as large doors are normally exempt from any guarantee) the resulting doors with Sing’s core inside are guaranteed for 50-years.

For fifty years they are guaranteed not to warp, bend, twist, delaminate, or otherwise fail for 50 years.

Zero Complaints

For many years, these companies who use this highly guarded secret, they have not had a single complaint, completely eliminating rejects, returns, and replacement doors, all because when necessary, they make sure their high-end doors have Sing Core inside.

We have been told that before Sing Core they constantly had complaints and recalls for these specialized large doors because they would fail due to warping or door or structure being compromised due to materials used or heavy weight.

The reason?

Sing Core is the only way to do it (that’s what they say) and they are backed by the best guarantee in the door industry without fail.

So, we highly recommend that you look into this if you would like to be counted among the best high end millworks and door companies.

Double French Doors Exterior

Exterior French doors are all the rage because if they’re done right, they offer superb safety and security while being Eco-friendly, lightweight, and fully insulated for increased sound deadening and climate control. The only way to create a sustainable lightweight pair of large double front doors that possess these double French doors exterior characteristics, which are also stronger than steel and guaranteed not to warp for 50 years, is with Sing Core inside.

 

Why is Sing Core so important for the most particular door afficionados in the world?

Granted doors with Sing Core inside may not be necessary for the masses, as standard doors available in standard door sizes are less expensive and adequate for normal everyday use. “Normal” doors move. The AWI standard for a normal 3-0 7-0 door is one-quarter-inch of movement, and the normal door industry from the door manufacturing companies, the hardware industry, and installation contractors all follow the guidelines of allowing a quarter-inch of movement without affecting normal door operation.

FRENCH DOORS

While you may think that glass is fairly stable, the frame which holds the glass (the French door) is subject to movement. It is the unforgiving glass which makes French doors more prone to failure, for if one corner is the slightest bit out of plum, the opposing diagonal corner will stick out like a sore thumb.

 

DOUBLE DOORS

Multiply the potential for failure times two, if you have two times the doors. A double door, two doors side by side, can potentially have uncooperative movement, even in normal-sized doors of 7 ft heights, double doors can have up to one-half inch of potential movement and still not be considered officially as warped doors, yet this exceeds the efficacy of the hardware, rendering the double doors inoperable.

EXTERIOR DOORS

To further complicate the problem with door movement over the life of a door which is more likely to move more often according to changes in the environment, and even more so, if one side of the door faces the structures interior and the other is exposed to the elements. This is the recipe for the perfect door disaster. That is why interior doors cannot be used as exterior doors. Exterior doors need to be made to different specifications to maintain the same “normal” quarter-inch movement allowed.

 

DOUBLE FRENCH DOORS EXTERIOR

As you may have guessed, by putting all these elements together in one set of doors, you have the makings of the greatest numbers of challenges associated with a single point of entry. Incredibly special attention should be in place when considering double French doors in an exterior front door application.

DOOR MATERIALS

While French doors may look like there is little at risk of compromising your egress point, there is much to take into consideration as each of the materials used in the construction of your exterior French doors has its own unique set of challenges as in integrates with the glass and its response to changes in environmental surroundings.

BIG DOOR PROBLEMS

The biggest problem with the door industry is with size. Normal movement of a door may be tolerable in a door that is 7 ft tall but once the door exceeds the 7 ft height, the rate of movement increases exponentially. The biggest problem with bigger doors is this increased movement which is referred to as door warp.

THE BIGGEST DOOR SOLUTION

Solving the problems associated with double French doors exterior is not a one-size-fits-all solution. Inventor Peter Sing’s patented and patent-pending door technologies are changing the way door are made around the world, and his True Flat Team is prepared to take on any unique and challenging combination of sizes, styles, and materials.

WHO TRUSTS THE SING SOLUTION?

The largest door companies in America trust Sing Core with their modern double front door solutions to provide their customers with the best in high-end double French doors exterior or interior, especially if they are very large in size, and they are backed by the best guarantee in the door industry: 50-years of flawless service.

 

50-YEAR GUARANTEE

Double front doors made with Sing Core inside can be guaranteed not to warp, bend, twist, or otherwise fail for 50 years, including full structure warranty and guaranteed not to delaminate. 50 years! No other door company can do that.

SUSTAINABILITY

No other lightweight Eco-friendly exterior double door promises flawless longevity like Sing Core, and while it is lighter in weight than other solid core doors, Sing’s patented core is high precision (+/- .0006-in. tolerance) and stronger than steel pound for pound.
