As a matter of fact, prepare to adjust your thinking, because thanks to Sing Wood Planks you can,
Say Goodbye to Tongue and Groove
Tongue and groove joinery is designed to keep wood planks flat when attaching because wood moves. Natural wood (or most any wood product) tends to warp, bend or twist due to environmental changes.
Not necessary when using Sing Hardwood that is created true flat and will stay flat indefinitely.
What if you needed to attach wood or tongue and groove planks to the surface of your Sing Panel?
Just make sure that you order your Sing Panel with the solid wood (or other material) implants to meet your requirements.
You can add stiles (vertical implants) or rails (horizontal implants) to have the anchor points that you need to match your expectations.
The only caveat, is that you must leave at least 12 inches of Sing Core material on either side of the implant in order not to compromise the sustained flatness of the lightweight, high-strength panel or door.
