What Are Sing Honeycomb Panels?
In the aircraft industry, they call it honeycomb. In the woodworking industry, it is called torsion box. In the home industry, it is known as 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.

How can I build with my Sing Core and Sing Core Panels?
A: The different options of our Sing Core and Sing Core Panels allows you to decide how you want to work with our technologically
advanced 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 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 to 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.


Do you have distributors?
No, at this time everything is sold directly by us from our manufacturing location in McCleary, Washington.


What do you keep in stock?
All of our Sing Cores, Sing Core Panels, & Sing Honeycomb Panels are made to order for each of our customers.


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, which is much lighter than standard plywood of the same size/thickness.


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 are the days and hours you are open?
We are generally in the office between 9 a.m. to 4 p.m.
Monday –Friday (Pacific Time) except for federal holidays.
Lunch is between 12 - 12:30 pm.


Isn’t Lauan difficult to work with?
Our Lauan 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.

How fast can you produce panels? We can produce hundreds of panels each day.

Where do you distribute?
We currently serve the United States and Canada.

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.
