Design Detail
PLYWALL® is a post and panel system consisting of prefabricated, preservative treated wood framed panels supported between preservative treated Parallam® PSL engineered timber posts. Prefabricated preservative treated wood framed panels are 8, 12, or 16 feet wide, covered on both sides with preservative treated exterior-rated 4’x 8’ Texture 1-11 plywood. The panels are typically 2 ¾ inches thick and are secured to the posts within channels created by pressure treated 4” x 4” cleats which are spiked or lagged parallel to the posts.
Pressure treated Parallam® PSL engineered timber posts support the panels at exposed heights to 24 feet (30 feet can be obtained under limited circumstances). Posts are embedded in the ground to a depth of roughly half the exposed height of the barrier and backfilled with crushed stone or concrete. Parallam® posts are much stronger and uptake preservatives far better, providing a much more durable, longer lasting barrier.
