About Jib Doors

Jib doors are also known as hidden or invisible doors because they are decorated to look like the wall with concealed hinges and hardware. It’s very important for your jib door to remain perfectly straight so as to maintain the seamless appearance in the wall hosting the jib door.

Little more is important in the creation and operation of a jib door than maintaining high precision over the life of the door. If the door warps, you lose the advantage of having a secret door that gives access to an otherwise inaccessible area. That’s when a door is no longer a door, as it just becomes another part of the wall, or will not secure properly, or exposes the otherwise invisible door because the material is either twisted or bent.

There’s one way to build a perfectly straight jib door, even if it is very large, and remain perfectly straight. In fact, inventor Peter Sing has been doing just that by providing the biggest and best door companies, millworks, and high end custom door manufacturers with his patented and patent-pending warp-free jib door materials. And that might leaving you to ask, “How good could they be?”

They are by far the best warp-free materials on the planet used to build the very best Eco-friendly lightweight high strength in the world, which can be

Guaranteed Warp-free for 50 Years

Let there be no mistake that Mr. Sing could not make a claim if even one of his high end clientele reported that his material failed, after being in service for more than 20 years. Sing has not had one such claim. This is his specialty.

Sing has created his top shelf True Flat Team, which designs and creates each custom door core which is built using his patented and patent-pending warp-free technologies to make incredible doors, even of enormous size, which will not warp, bend, twist, cup or otherwise fail, including delamination, for 50 years.

There is no other way to accomplish such a feat, and as you might have guessed, if there were such a way, those big door companies would be doing it. To this day, they admit,

There’s just no other way to do it.

Jib Doors

Jib doors must maintain the seamless appearance of just being a part of the wall, except in the instance of a bookshelf doorway, where the door itself is also a functional bookcase on one side of the door using the same concealed hinge and door securing mechanisms as the invisible or hidden door, like these classic hidden hallway doors.

Of course, it all depends on the size of the opening and the construction of the existing wall that will host the jib door, too. The hidden door will have two vertical seams which need to remain flawlessly straight and true to remain invisible to the naked eye. Unless the doorway will span from floor to ceiling, there will be a horizontal seam at the top of the door which may also need to appear the be seamless.

Hailing from the Old World, jib doors have made there way to the Americas. While no longer used to conceal clandestine activities, including one or more jib doors in your contemporary architecture design project is growing in popularity and is influencing the design, engineering, and building of invisible jib doors. There is no longer any suspicion or negative implications, or having to answer the question, “Why do you have a jib door?” Jib doors are a growing segment among modern doors.

If your jib door is warped, the seam will become visible thereby defeating the purpose of having a hidden door if it no longer appears to be an invisible door at all, and the door’s secret is blown. That’s where Sing Core comes in.

Millworks and high-end custom door manufacturers know they can rely on Sing Core’s ability to provide a warp-free job door blank which will remain straight and true enough to protect the hidden door’s secret of invisibility over time.

If you’re dreaming about having a very large jib door, like a floor to ceiling full moveable wall, Sing Core’s light weight (weighing-in at a fraction of other solid jib door cores) and high strength (660+ PSI, stronger than steel pound for pound) enables architects, designers, and engineers to realize a full articulating wall, which can pivot, swing, or slide open and closed easily via cell phone. Where there once was a wall, there is none and you have full access to the space.

Make a Whole Wall Disappear

Then there’s this case; What if you wanted the whole wall to be a door. Here’s a job where the client wanted to whole exterior wall converted to bifold jib doors. No problem, if they have Sing Core inside.

Just an ordinary exterior wall. Right?

Extraordinary exterior bi fold doors!

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.

And if that’s not enough to make you insist on specifying Sing Core inside your next architectural jib door, consider this:

Your jib door could be backed by inventor Peter Sing’s unparalleled 50-year warp-free guarantee. Sing’s jib door cores are guaranteed not to warp, bend, twist, or otherwise fail (including full structure and delamination) for a full 50 years.

No other Eco-friendly lightweight high strength door can compare in terms of weight vs dimensional stability.

A Unique Addition to Your Project

Nothing sells a finished product like the little touches. When you think that everything else has been tried, consider adding a hidden door to your project.

Hidden doors allow for additional space utilization in a design while minimizing visual clutter due to door framing and hardware. This gorgeous example, built by one of Sing Core’s clients using our patented lightweight honeycomb technology, oozes refinement and class. At a glance, the door melds in to the hallway molding and leaves the lines unobstructed.

Our Panels are Your Canvas

An artist cannot paint without a strong canvas, likewise a builder cannot make living art without strong building materials to form their creations.

Sing Core door slabs come with a 50-year warp-free guarantee that demonstrates the underlying stability and quality of our materials. We stand by our ability to create doors that are:

Lightweight

Sound proof

High insulation value

Straight

Strong

and Dependable

When You Client Demands the Best

May companies on the market offer a variety of door cores. We acknowledge that our product is not the right solution on all situations. For doors of usual sizes and applications, or exacting production standards leave little flexibility in pricing to meet budget demands. Where our doors shine is in very large, high tolerance, or very high end applications.

When all that maters is the best possible outcome for your project, then remember Sing Core and our patented and patent pending “honeycomb” door technology cannot be beat.

Smooth, Flush Trim, and Anything You Can Imagine

Flush is just the start of the possibilities when it comes to high end custom doors. With Sing Core almost any possibility to can be realized. Almost any size can be realized using the unique strength and straightness of our honeycomb core. Too thin and too big are not in our vocabulary.

The real question is how big can you imagine? What do you and your clients seek to realize?

A Miraculous Material

Many people are surprised to see how much then can accomplish beyond the norm with Sing Core backing their work. For us strength is really not a problem. Warping can be relegated to a fear of the past.

We would be boosting to say these things if the product didn’t warrant the praise. But in this case we can, in humility, say that what we provide top end millworks, construction companies, and architects pushes the boundary of what is possible.

When you use Sing Core you are in the driver’s seat. Do you want metal skin, solid wood skin, paint, plastic, fiberglass? Almost anything can be realized with less weight and greater strength than even aluminum or other space age door technologies.
