Tongue & Groove Carsiding Planking

Tongue and groove planking and carsiding for interior walls, ceilings, and porch soffits.

Coverage is not the same as the board width. The tongue and the lap take up part of every board, so ordering to the raw wall measurement leaves you short. The tongue and groove calculator works out the real coverage from your wall dimensions and adds an allowance for cuts.
