RD1 Roof Deck

The OneDek®RD1 flat roof deck panel combines into a single component steel deck, insulation, air / vapor barrier and substrate necessary for field application of a white, single-ply TPO or PVC membrane for low slope roofs.  RD1 is high performance, sustainable and an economic alternative to field-assembled roof deck systems.
