About Hidden Doors

Hidden doors, or jib doors, are the most particularly demanding for high precision because any misconfiguration or door warp will make an otherwise invisible door stick out like a sore thumb (literally), and if it’s too far out of plumb, it may not operate at all.

Thanks to inventor Peter Sing’s patented and patent-pending hidden door technology, you con create a flawless, high precision invisible hidden door that will operate without fail. other advantage of using Sing’s core within your hidden door include possessing an Eco-friendly door that is fully insulated for sound deadening and climate control, lightweight (one-third or less the weight of other wood based solid core doors), high strength (at 660+ PSI, stronger than steel pound for pound), impact resistant (Sing says, “kick my door, break your leg”), highest precision (Sing Core sports .006-inch tolerances), and here’s the kicker,

50-Year Warp-free Guarantee

The only way in the world to build a sustainable lightweight high strength hidden door that can be guaranteed not to warp, bend, twist, or otherwise fail (including delamination) for 50 years, is to have your door build with Sing Core inside.

Sing Core is known for it’s large, showy doors. But, our lightweight door technology has many varied applications. Whenever style and durability are a factor, Sing Core panels deliver where others cannot.

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.

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.

What Can We Do For You?

Although we aren’t the right fit for every project, when your design has unique needs remember that Sing Core is there to back you up.
