Invisible Doorway

Hidden “Jib” Doors

A door that is hidden in plain sight is commonly referred to as a “jib” door. Jib doors can often be called invisible doors or frameless doors. This type of door traditionally sits flush with the wall and matches any pattern on the wall. Jib doors provide a camouflage entrance to “secret” rooms. Everyone loves a house with a hidden door or secret rooms. We can provide jib doors, concealed cupboards and riser door systems perfect for concealing unsightly riser doors, access panels and service cupboards.

Essentially, it’s a door that is flush-mounted right into the wall—and often without hardware—essentially making it “invisible.” Sing Core provides lightweight and high strength door panels. These panels are crafted with the utmost precision. Sing Core’s door panels are comprised of a specially designed torsion box honeycomb core. This special design prevents warping, even in greatly over-sized doors. Sing Core is one of the only door companies who can guarantee their doors for 50 years. No other door company can make this claim!

Known for their essential “invisibility,” jib doors are flush-mounted directly into the wall allowing them to blend beautifully with their surroundings. The most subtle jib doors often lack any visible hardware. Bookcase doors work perfectly as entrances to panic rooms or vaults for storing firearms, jewelry, documents and other important items. A jib door is nearly invisible, or at least disguised from being recognized as a door. It may have the same moldings or wall treatment as the surrounding wall, creating a door hidden in plain sight.

What is the purpose of a jib door? A jib door or set of jib doors allow you to disguise that old broom closet so no one would even know it is there. Jib doors are very popularly used to keep precious valuables safe and secure. More importantly, jib doors can and are used to conceal your home’s panic room. A jib door is only hidden as well as it is made precise. Do not take any chances, and let Sing Core build your very own custom jib door. Sing Core offers precision unlike any other door company out there. This being said, we can manufacture the most seamless jib doors on the market.

Sing Core builds the most high end and lightweight doors on the market, and remain economically friendly! We custom build every door by hand to ensure the utmost precision as well as the utmost customer satisfaction. Plus, if your invisible door has Sing Core inside, you get the added safety and security of having a fully insulated sound deadening jib door which is also highly effective in maintaining consistent temperature control on either side of the wall door.

Millworks and high-end custom door manufacturers know they can rely on Sing Core’s ability to provide a warp-free door blank which will remain straight and true enough to protect the hidden door’s secret of invisibility over time. Not only can Sing Core offer the utmost precision, but we can offer precision that lasts longer than any other door company. Traditional door materials; such as solid wood, hollow core with MDF, or plastic tend to warp as they age and some are warp the day you purchase them! Sing Core guarantees that every door produced will not warp or fail, and this is backed by the Sing Core 50 year guarantee!

Only inventor Peter Sing’s warp-free veneer substrate can keep your veneers and laminations from warping over time. This is especially important in free-standing applications, such as temporary walls, display walls, and large doors of any size.

When your veneers or laminations are applied to any flat surface, like a wall or a floor, you have nothing to worry about when it comes to unexpected movement, but these free-standing applications are always a problem when trying to keep your product straight.

The application for which Sing Core is unsurpassed in superior performance is that of large doors. Door companies that long ago refused to make large doors due to the liability of warping not long after installation, are now making the biggest doors available to their custom clientele. That’s why architects spec Sing Core inside. See The Secret Revealed: How to Keep Large Doors Straight.

Secret Revealed: How to Keep Large Doors Straight

Inventor Peter Sing discloses how he and his True Flat Team can build enormous doors of any size and/or material and keep them straight and guarantee them to remain warp-free for 50 years.

 

First, there is the standard answer. Sing uses his patented torsion box hybrid composite core to build large doors that will not warp. Doors with Sing’s patented core inside are Eco-friendly, lightweight, high strength, and are fully insulated for increased temperature control and sound deadening capabilities.

How is it possible to build a large warp-free door?

This question is indicative of the problem facing door companies with doors over a standard height. If a door is over 7.5 feet tall, it is generally excluded from the warranty which might cover the rest of the doors in the build package. You will have to sign a waiver if they do decide to build the big doors for you, but it is more likely that they will have you get it from someone else.

 

Why?

Because they know there is the likely inevitability that those oversized doors are going to warp at the next change of season (or sooner) and they don’t want to be hassled with servicing the warped door.

How to Build a 50-year Warp-free Door

While the simple answer is to use Sing’s patented core, it is far more complicated than that. Peter Sing and his True Flat team have a toolbox full of patented and patent pending anti-warp technologies that they use on each large, oversized door, as no two huge doors are alike. Well, unless they are a pair of matched double door, then they are likely to be the same.

 

There are so many considerations that Sing and his team review prior to deciding how to build the door. First, it is the door’s dimensions. The bigger the door, the more engineering and warp-resistance needs to go into the door.

Then it is the door’s application. Will it be interior or exterior? Will it be exposed to the elements? If it is an exterior door, what area of the country will it be located? What altitude will it be installed at and which direction will it face?

Finally, what will the intended exterior surface material be made of?

 

The best parts are under the skin

Under the skin, the exterior surface material of the door, you will find a complex array of Sing technology fighting against the natural inclination of these big doors to move in response to any change in the local environment, including moisture, barometric pressure, heat, cold, just about anything you can imagine, Sing has a technology to keep that door straight.

In the most extreme cases, Sing’s team might be exposed to something new. A new unforeseen challenge, like wood grain’s reaction at high altitudes, or concrete in extremely cold temperatures. Necessity is the precursor to invention, which leads to another new patented Sing solution.

Then there are other considerations to take into account.

Are there any specific expectations such as final door weight, water, fire, sound, or bullet proofing? Impact resistance? Insulation R-value?

Every door with Sing Core inside is a work of art

As you may have guessed, a door that is going to be operated mostly in outer space (NASA) would be built quite differently from a door used in a submarine (US Navy). Just like an exterior front entry door made for Hollywood California would be different from a front door in New York City, even though they look the same and are made of the same basic materials.

Sing and his True Flat Team take all these things in consideration to make sure that the door you install today will not warp tomorrow, or anytime in the future (up to 50 years guaranteed).

This enables the biggest and best door companies in the world to build the biggest and best doors in the world complete with Sing’s 50-year guarantee.

It’s the only way to do it, and all you have to do is to contact your favorite custom door manufacturer or millwork near you and tell them you want a door with, “Sing Core inside,” and Peter Sing and his team will make sure you end up with a lightweight high strength warp-free door you can be proud to have for 50 years or more.

Interior Pocket Doors

Need to make a small room seem bigger? Tired of the footprint taken up by the door swing? A pocket door could be the perfect solution to these issues. Pocket doors have their origins in Victorian homes where they often separated formal seating areas or entry ways. A pocket door is a type of sliding door. Unlike a regular door, a pocket door slides in and out of a wall on a track. Sliding Pocket Doors are a great way to conserve space. Similar to sliding barn doors, pocket doors have the ability to be hidden within a wall. Pocket doors are the perfect portal for powder rooms, laundry rooms, pantries or utility rooms. In small areas like these, a standard swinging door would take up a significant amount of space.

What is a pocket door and how does it differ from a regular door? A pocket door is a type of sliding door. A pocket door slides into a hollow cavity, or “pocket,” in the wall.

Pocket doors maximize under-utilized areas around doorways and transform them into smart storage spots. A pocket door simply slides into a frame in the wall, freeing up a great deal more of the room and opening up the design possibilities.

Sliding pocket doors were very popular with turn of the nineteenth century builders and they can be seen in different style and design such as double pocket door. An open interior door breaks up the line of the wall and can look a little clunky.

Pocket doors disappear completely when open, creating an elegant, streamlined appearance. Sliding pocket doors are useful in designing two separate rooms, so that they may be joined as needed. Pocket doors don’t seal a room as tightly as a traditional swinging door, and the typical locking mechanism is flimsier than a tubular latch or deadbolt.

This is why sliding pocket doors are best used as interior doors. Pocket doors are an interesting addition to many homes because they slide into the wall, hiding the door when open. Most of you already probably know this, but for those who don’t, pocket doors are interior doors that “disappear” into a shallow slot inside a wall.

When it comes to saving space, pocket doors are loved by designers, builders and homeowners alike. A pocket door is a great way to pick up usable space that’s normally occupied by a swinging door. Sing Core creates sliding doors and pocket doors for stylish, intuitive, and space-saving solutions.

These pocket door frames are made of sturdy wood, with a skin of your choice. We can provide veneer, wood stave, aluminum, hot or cold rolled steel, and much more!

Here at Sing Core we specialize in custom doors, so if you can think of it, then we can do it! Let us help you with your next project. Sing Core produces the most accurate door panels on the market.

Sing Core is the only company to produce over-sized doors that are structurally guaranteed for 50 years. No other door company can structurally guarantee their doors for 50 years, even their standard sized doors.

What Is A Pivot Door?

A pivot door rotates on a pivot box in the floor and the top jamb rather than traditional door side hinges, which is common in most homes. Pivot Doors have become a popular choice for entrances, creating a bold statement at your first point of contact.

What makes pivot doors so unique? The pivot door or pivot window is an opening system with a central or lateral rotating axis that allows for very large door panels. The craftsmanship and technology of a pivot hinge allows for a larger opening than most other types of doors since traditional hinges cannot carry the same kind of weight. Pivot doors are fantastic options for where there is a large amount of space and enough floor room for the door to be able to swing all around.

Grounded in the principles of modern architecture, a pivot door emphasizes clean lines and simple shapes. Pivot doors are well suited for pivoting walls and can also be used as room dividers. Until now, affordable pivot doors are thicker than average doors and heavy in weight. The large size and heavy weight causes extra costs associated with shipping and handling. Shipping is more expensive because shipping costs are calculated on weight. Handling is more expensive because heavy equipment is necessary for transporting and manipulating the pivot door into place for installation. Pivot door hardware is also based on the affordable pivot door’s weight, so a heavier pivot door will require more expensive and heavy duty hardware. Here at Sing Core we manufacture custom premium wood pivot-hung entry doors for exterior and interior use. Our pivot doors feature our patented lightweight insulated torsion box pivot door core inside. Which imbues each door with the unique characteristics of a solid core pivot door featuring the exact size, material and appearance of any style of pivot door, while remaining extremely lightweight and incredibly strong. Independently University tested at 660 PSI, makes Sing Core’s pivot door core stronger than steel pound for pound. The pre-insulated core also means greater climate control and noise cancellation between spaces. Also, the lightweight of Sing Core’s pivot doors, means less shipping, handling, transportation and installation costs, requiring less expensive hardware.

A pivot, not a hinge rather than hanging from hinges in the frame, a pivot-hung door swings on a set of pins mounted in the top and bottom of the door. Transform the look of your home or office by opting for Sing Core’s affordable pivot doors. Pivoting front entry doors provide an elegant look and appear to float inside the door frame. We are offering premium wood pivot-hung entry doors for exterior and interior use that cannot be found anywhere else. Let Sing Core build your custom pivot doors, custom modern entry doors, exterior mahogany wood doors, or any other custom door you can imagine! If you can create the idea, we can create the door. Every Sing Core door comes with a 50 year structural guarantee, something that no other door company has been able to offer.

Pivot Door 50 Year Guarantee

There have not been many truly significant advances in the manufacturing or pivot doors in the last hundred years, until now, with the invention of patented Sing Core which offers the only pivot door 50 year guarantee for a large custom eco-friendly lightweight high strength door.

Such a door could not be built before. In fact, when the largest door companies were approached with building a large custom pivot door, they turned the job away, because while such a door could be built and look spectacular when installed, it would not be long and the door would fail.

Large custom pivot doors were manufactured by high end millworks willing to do the work and charge the prices commensurate with a high degree of craftsmanship with reliable regular maintenance over the life of the door because the key to making these large pivot doors work over time would require a heavy maintenance schedule to straighten the doors that were known to warp and need repair periodically (potentially every change of season depending on the climate and geographic location of the big pivoting door).

This was the case of every large pivoting door over three-and-a-half feet wide and seven-and-a-half feet tall, especially if they were large wooden pivot doors. Natural wood tends to want to move according to any change in the environment. The result? Large warping pivot doors.

Enter inventor Peter Sing’s patented large pivot door core which empowers high end millworks and the biggest door companies in America to build the biggest lightweight high strength pivot doors in the world that can be

Guaranteed Warp-free for 50 Years

Inventor Peter Sing created a hybrid composite core and anti-warp technology to build large pivot door cores that could support the weight of any exterior material and stay straight and true. Sing’s True Flat Team helps to design and create the perfect door base material to accomplish the goals of the architects, designers, door engineers, artists, and end users, with no risk of warping doors.

The technology is based on a melding of new and old technologies using Sing’s out-of-the-box approach to problem-solving. Start with a basic torsion box design (traditional method of building large flat wooden products) but flip the grain of the torsion box frame on its side so that it lays perpendicular to the stress skins. Then before you apply the stress skins fill all the empty cavities inside the torsion box structure with rigid recycled foam. Cold-press with formaldehyde-free glue for a basic warp-free base material.

That’s the basic formula, but there are type of woods and other building materials which have a greater propensity to warp than others. Sing’s True Flat team reviews each door and determines if extra patented and patent-pending anti-warping technologies will have to be added to the door to keep it from warping, especially if it has a surface material with a greater potential to warp.

The Warp-free Pivot Door 50 Year Guarantee

Is a science which Sing has mastered. And just when you thought that might be all you might expect from any pivot door with Sing Core inside…

But Wait. There’s More…

All of Sing’s pivot doors also have an impressive list of features that you would be hard-pressed to find anywhere else, except for Sing’s factory located deep in Washington State’s scenic Pacific Northwest. They also offer,

SOUND DEADENING

For added safety and security for you, your family, at work, in scientific, government, and military applications. This is why you see Sing’s core specified in the best soundproof doors.

CLIMATE CONTROL

At least R3.5 per inch (R-value can be increased to match your performance expectations) of Sing Core give’s you more separation from the elements or greater temperature control in heating or cooling environments.

HIGH PRECISION

If you are looking at a lightweight high strength building material, Sing’s core can meet or exceed your precision expectations as it hosts high tolerances throughout (+/- .006 in.).

LOW MAINTENANCE

In side by side comparisons, pivot doors with Sing Core inside require less maintenance over time than any other door because, simply stated, they do not warp, cup, bend, twist, not otherwise fail.

LONG LIFE SPAN

Sing’s doors are designed and built to last for centuries but guaranteed to perform fail-free for 50 years. No other eco-friendly lightweight high strength material can do that.

Add to those characteristics, the following attributes:

LIGHTWEIGHT

A fraction (at least one-third less) the weight of other wood-based cores or their alternatives.

HIGH STRENGTH

Able to span long distances and carry loads with little or no support. Unbelievable unless you’ve had the opportunity to handle a Sing door first-hand.

WARP-FREE

No other material can compare to Peter Sing’s uncanny ability to build doors that just will not warp. Sing Core is the reason door companies, millworks, and custom door manufacturers are back in the business of building large pivot doors again.

50-YEAR GUARANTEE

The only door in the world guaranteed not to warp, fail, or delaminate for 50 years.

This is why more and more you are able to find Sing’s patented tech anywhere from beneath the sea (US Navy) to outer space (NASA) and everywhere in between.

Horizontal Wood Staves

Give your home the humbling, yet astonishing ambiance of the Kekkai, the Kyoto code, by using horizontal wood staves.

What is Kekkai?

The Japanese principles of Kekkai are very simple. A Kekkai is a boundary comprised of a simple, often vague, line or sign indicating a place of no entry. In Japan, Kekkai can be anything, but commonly used objects for creating this boundary can be a piece of bamboo, pile of salt, a rock, a gate, or even mountains are considered Kekkai. The vagueness gives everyone an opportunity to interpret the exact meaning behind a Kekkai. Usually it is a boundary, but it can also be used to show respect. The use of Kekkai in this way indicates your position and how others should behave in the given area. They are used to convey a symbol of respect between all things, living or not. Kekkai embodies the “spirit of consideration” for those who use them and those who are aware of them.

Ninety percent of our customers who choose to have a wood stave skin on their door/panel prefer the horizontal wood stave instead of the vertical wood stave. Wood staves are a beneficial choice when choosing a skin for a door/panel. What are wood staves?  A stave is a narrow length of wood, in our case usually 6 in., that runs the span of the piece. They are aligned on the edges to leave no gaps. A stave traditionally forms the sides of barrels and is now a great material to use for your next DIY project. Stave lumber cores are assembled using blocks or strips of wood that are from the same species. Wood staves usually have a thickness of 0.125 in. while veneer is only 0.020 in. thick. Wood staves are 16% thicker than a standard veneer skin. This may seem small and insignificant but it makes the door/panel much easier to repair. The engineered construction of our interior doors utilizes fused, solid wood pieces that are laminated to create a solid wood stave face. Wood staves can be used on any door; including but not limited to: pivot doors, sliding doors, even standard hinge doors. Wood staves are offered in a wide array of species of wood, including mahogany, which is a beautiful species for a door. There are too many types of wood to list, but if you can think of it, then we can do it!  Our selections includes domestic and foreign hard wood lumber and softwood lumber. Our wood stave selection cannot be matched! Solid wood doors tend to warp, which is why most doors should use Sing Core. Solid wood doors tend to warp, so choose Sing Core for your non-warping needs. Sing Core carefully engineers doors to withstand the test of time. We create the strongest, lightest, and most eco friendly doors for a fraction of the cost you’ll see anywhere else. Our doors all come with a 50 year guarantee that they will remain this way. Think of Sing Core the next time you need a core for your door. At Sing Core we use only the highest quality wood for any commercial or residential applications you need.
