PWF - 2-in x 8-in x 8-ft

A permanent wood foundation (PWF) is an engineered construction system that uses load-bearing exterior light-frame wood walls in a below-grade application.

A PWF consists of a stud wall and footing substructure, constructed of approved preservative-treated plywood and lumber, which supports an above-grade superstructure.

Besides providing vertical and lateral structural support, the PWF system provides resistance to heat and moisture flow.
