In the woodworking industry, it is called a torsion box.  In the home industry, it is known as a sandwich panel.  No matter what you call it, Sing Core’s honeycomb panels have the strongest, most lightweight earth friendly core to structure your Sing Core panels.  Sing Core panels has more applications than any known material; use it for home construction, boat building, private jet furniture, home furniture, museum and trade show display, and doors.  Patented Sing Core panels are a hybrid of torsion box, sandwich, and honeycomb panel.  It has the flatness of a torsion box, the strength of a honeycomb panel, and the light weight of a sandwich panel.  Sing Core panels combine all of these characteristics to form the most earth friendly panel in the industry.

Our panels have a solid wood frame and block inserts can be implanted inside the panel to create secure anchoring points. Anchoring points can be used for placing hardware, overlays, and even fastening the panel.
Stiffeners can be implanted to ensure a true-flat panel. The necessity for stiffeners depends on the overall size of the panel, application, and weight.
For more information, see our custom blocking page.

 

What are your skin options?

Skin choice is one of the biggest factors to avoid warping.
It is important to choose a skin that is non-permeable. Permeable skins allow moisture to be trapped in the skin material causing it to swell. This can cause structural issues over time.
Wooden doors have the most problems with moisture absorption.
It is important to specify exterior grade when needed for your application.
Skin choice can affect sound deadening capabilities and is important for adhering to a certain Sound Transmission Class (STC) rating.

Can I have dissimilar skins on my panel?

Dissimilar skins may be possible depending on your panel’s thickness. Please discuss this with your sales representative for more information.

Do I need to calibrate my panels before veneering?

Yes.

How do you handle such large doors?

Oversized panels are panels with dimensions over 4’ x 8’.
Oversize panels are often more difficult to handle and more costly to ship.
Luckily, we have devised a method to overcome this. The Sing Spline allows us to ship oversized panels in modular sections that can be joined at the work site. See Sing Spline for more information.
Almost any door can be made with Sing Core. Stile and rail style doors can be made by simply adding trim or molding pieces; however it will be much stronger than a traditional stile and rail door.

What is True Flat?

All Sing Core products are guaranteed true flat; that is to say that they far exceed AWI industry standards or ¼ inch deflection to be considered flat.  Specific degrees of flatness can be achieved and guaranteed based on your requirements, specifications and application.  See What is True Flat? for more information.

Sing Core Structural Core Honeycomb Core which is based on Torsion Box technology to be lightweight but strong. You would then add skins and edging as you desire.	Sing Core Panel – No Edge Sing Core that has a skin on the front/back of it, which improves its strength and gives you a working palette for your project. You would then edge band as desired.

Why Do Sing Core panels have such a long lifespan?

Patented Sing Core panels use zero formaldehyde structural glue to bond Sing Core and the surface material creating the strongest lightweight eco-friendly sandwich panel/honeycomb panel, see comparison.  The patented Sing Core panel is nearly unbreakable due to being so lightweight and strong.  Even if damaged by rough handling, Sing Core panels can be repaired to their original strength (Our patented structural core and stress skins are much easier to repair than solid wood, MDF or plywood).

 

What is the weight of your panels?

The weight of our panels are based on many factors, W x H x T, the types and thickness of the skins chosen and of course the solid wood edging as well.  But for a rough ballpark estimate the weight of one of our standard panels 4’ x 8’ x 1” (finished size = 47” x 95” x1”) is somewhere in the 25 to 30 lbs range depending on the skin, which is much lighter than standard plywood of the same size/thickness.

What is a “board foot”?

12″ x 12″ x 1″ = 1 Board Foot

12″ x 12″ x ½” = ½ Board Foot

12″ x 12″ x 2″ = 2 Board Foot

 

What if I want 1/4″ MDF?

Instead of 1/4 inch MDF, we use our own plywood-backed MDF which is made by laminating 1/8″ plywood to a 1/8″ sheet of MDF.  This still gives you the smooth MDF face to paint, hot press to, or apply other materials, like vinyl wrap(s).  You get the same smooth surface with added high performance because MDF is prone to movement.  If you have to have 1/4 inch MDF, we will make your panel to your specifications, but we may have to re-engineer the rest of the panel to assure high performance.

Will Sing Core’s spline joints crack?

Because of the stability of the patented Sing Core, spline joints in sectional Sing panels/doors will not crack, unlike traditional solid wood which is not stable enough to be used in this application.
