Installation Guide
Install shiplap horizontally or vertically. For horizontal applications, start with
the bottom course and work up with overlap pointing downward. Do not nail
through overlaps. Shiplap siding is tight-fitting, so butt the courses up close.

Interior Installation
• When installing Thermally Modified Wood on the interior of the home,
it is not necessary to install over “batten strips” or rainscreen.
NOTE: (For non end-matched/8-foot length boards) Prior to installation
and for best results, check for square and trim all uneven board ends.
• The boards should be fastened in a similar fashion to interior wall studs.
Adhesive may be used to reduce the need for fasteners.
