What Are Sing Panels?
In the aircraft industry, they call it honeycomb. 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 Honeycomb Panels have the strongest, most lightweight earth friendly Sing Core to structure your Sing Panels. Sing Panel 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 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 Panel combines all of these characteristics to form the most earth friendly panel in the industry.

What is the difference between your Core and your SingCore Panels?
SingCore 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.
SingCore Panel – No Edge
SingCore 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.
SingCore Panel – With Edge
is the complete panel
for your use, with core, skins and solid wood edging this is ready to then be completed and installed by you
for your project.
What edging options does SingCore provide?
Sing Panels can feature a 1.25 inch solid wood edging. Other sizes are available as custom options as well. Edge-banding is available at an extra charge. Sing Panels can also be purchased without an edge.
Why Do Sing Panels Have Such a Long Lifespan?
Patented Sing Panels use zero formaldehyde structural glue to bond SingCore and the surface material creating the strongest lightweight eco-friendly sandwich panel/honeycomb panel, see comparison. The patented Sing Panel is nearly unbreakable due to being so lightweight and strong. Even if damaged by rough handling, Sing 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).
How is pricing calculated?
Our price is based on the quantity, length, width, thickness, and type of skin (choice of plywood, MDF, solid wood, aluminum, fiber glass, stainless steel, hardy planks, etc.). All Sing panels are sold by price per square foot, so if you need strength, light weight and true flatness, patented Sing Panels are an excellent option.
We make cut to size panels, posts and beams to build the smallest shelf to the largest door or you can even build an entire house (Click here to see an entire Sing Home build with Sing Honeycomb from foundation to roof within 3 days for the California home show in San Jose). All products can be ordered through our pricing page. This includes panels for girdles, joists, floors, walls, roof trusses, roofs, doors, window frames, kitchen cabinets, and countertops.
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’s the difference between Standard and Professional SingCore panels?
Standard panels provide more than enough structrual integrity and non-warping properties for most jobs, but for jobs that require true flatness, we also offer a Professional tier of SingCore Panels. Professional panels come with a 50 year non-warp guarantee that feature our aluminum stiffener technology. Learn more about SingCore Professional Panels here.
Can you nail into a SingCore panel?
Yes. We recommend a ⅜ inch skin such as MDO or luan if you plan doing a good amount of screwing or nailing into your panel. You can also nail into a SingCore panel with a ⅛ inch skin as required.
Our craftsmen can also install custom blocking for your projects at an additional cost. Please provide drawings so we can ensure a precise panel.
- We can place custom hardware in your panels as required by your drawings.
- Install a solid wood strip every 12 inches (or whatever your needs are).
How much wood do I need around the perimeter of a door panel?
The standard wood trim inside the perimeter of a Sing door panel is 1.25 inches. Old school technology would have you thinking that you might require a heftier wood frame inside. While that might be true for a hollow core, paper core, or other type of core door, it is unnecessary when using Sing door core as substrate. Sing Core is a composite solid core material which is stronger than steel pound for pound, and is often used for attaching hardware without the use of implants.
Even so, we do offer solid wood implants, like lock blocks, or any other location to accommodate your hardware specifications.
What are the lead times for new orders?
Lead time for new orders is 4-8 weeks. Every order SingCore manufactures is custom made, so please bear that in mind in regards to your project’s timelines.
If you require a rush order, rush fees are as follows:
Ship in 4 weeks – 20% price increase
Ship in 3 weeks – 40% price increase
Ship in 2 weeks – 70% price increase
Ship in 1 Week – 100% price increase
Rush fee times are counted from the day we receive payment or deposit for your project.
Exactly how strong are your panels?
The strength of our panels depends on factors like span, thickness, and skin type. They have been independently tested by the University of Washington to exceed 660 PSI, and can be custom designed to achieve over 1,000 PSI per your specifications.
How well insulated are Sing Panels?
The R-Value of a Sing Sandwich using EPS Foam is 3.5 per inch. For technical specifications on our EPS foam, please visit this page. The R-value of a Sing Sandwich using Urethane Foam is 6.5 per inch.
How big can you make Sing Panels?
A standard sized panel is 4 ft. x 8 ft. We also specialize in custom sizes, which are available in any dimensions, up to 22 ft. by 40 ft. or larger.
Can you join together Sing Panels?
Yes. One way to join Sing Panels is with a biscuit. View this video to see how to join panels, or visit this page.
Can I bond other materials to the surface of Sing Panels?
Yes. Many of our high-end millworks adhere other surface materials to a Sing Sandwich when used as substrate. Standard lightweight plywood surfaces are easily adhered to with regular carpenter glue and cold-pressed. If your intention is to laminate other materials to your Sing Sandwich, you should check with us first, to make sure that you are using the proper bonding agents) to achieve the results you desire.
Are your lightweight panels weather resistant?
Our panels are resistant to the degree of its surface material and/or its coating. Sing panels can be manufactured to withstand the most extreme weather conditions, and are even used in underwater applications.
Where do you distribute?
We distribute to anywhere in the world, and have delivered panels to Europe and Asia.
Do you do any licensing of your patented products?
We’d be happy to discuss licensing and partnerships. Please get in touch with us via our contact page.
What types of material can I laminate to honeycomb?
Any substrate (skin) that is capable of carrying a load.
What is a torsion box?
A torsion box is best explained by this article.
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
Can I get sizes besides 4’ x 8’?
Yes, sizes smaller and larger are available, but you need to email us your custom sizes W x H x T and we will work with you to get a quote together.
We can manufacture panels up to 5’ x 10’. However, the most commonly ordered and most economical is our size 4’ x 8’* (*finished size is 47” x 95”) and that is because we’re usually limited by the size of the skins available and whether you can smooth out the seams between skins for larger sizes. Sizes are also limited by shipping company restrictions.
How much pressure do I use to apply skins myself?
Enough for intimate contact with our honeycomb core with or without solid wood edging but too much pressure can cause damage to the core.
How can I build with my Structural Core and Panels?
A: The different options of our SingCore Structural Core and SingCore Panels allows you to decide how you want to work with our patented core material. You can choose how much or little work you want to apply to the core*. (*when applying skins you will need to use a cold-press method)
Purchase just the core, you would then apply the skins on both sides and solid wood edging* (*place edging before apply top skin) or
Purchase core with skins* (*birch or luan) and apply the edge-banding or yourself or hire someone to do it or
Purchase the core as an all in one component* (core, skins (birch or luan) & solid wood edging)and receive your panels complete, just paint/seal and finish as you desire and install
What does paint grade not paint ready mean?
We deliver your panels as paint grade as opposed to paint ready, due to several instances where our definition of paint ready did NOT meet our customer’s definition of paint ready. Because of these issues, we now leave it up to the customer to get their panels to their preferred finished state.
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.
What surface materials are available for a Sing Sandwich?
·Our standard surface material is Luan (lightweight plywood).
What are the fire retardant qualities of our product?
Foam: level 2, Panel: untested
How do you ship?
LTL Freight Company – common carrier
Arrange for pickup by your preferred carrier
Customer pick up from our facility here in McCleary, Washington
How do I seal the interlock?
It can be sealed with conventional caulking or waterproofing.
Isn’t Luan difficult to work with?
Our Luan is in the form of veneer, so the natural fragility of the wood isn’t a factor.
How do you fasten panels?
Fasten your panels with dowel, bolts, biscuit, camlock (rotorlock), or edge to edge glue. Visit our Fastening Page for details.
What kind of wood do you use for solid wood edging?
We use soft wood because it’s easy to control the moisture content and to fasten. Soft wood also weighs less than solid hardwood.
What if you use a basic interior door as an exterior door?
It’ll bend because moisture will get inside the door and press outward on the skin. We don’t guarantee for weather exposure because we don’t control how you treat the surface. If treated properly with urethane, your doors can withstand the weather.
Will Sing 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.
