How is PermaBase Dek used in roofing applications?
PermaBase Dek functions as a support board and/or cover board for the insulation. It also functions as a support board for approved membranes such as ballasted systems, liquid membranes and mechanically fastened membranes. PermaBase Dek will not swell or rot in the presence of moisture and has a high indentation strength to protect the insulation and support the membrane.
