WHAT IS THE TOTAL THICKNESS OF THE SIDING INSTALLATION?

The total thickness from the outside of the board and the substrate, when the US09 profile, is used is 1.25 inches, and with the European siding is 2.25 inches. This includes the board (including the portion that goes into the clip), the clip, and the furring strip. This may vary a little based on the furring strip used, but we would recommend a 1×3 furring which is usually 0.75 inches thick.
