Fire retardant synthetic roof underlay to provide strong resistance against air and moisture with excellent water vapour permeability
DuPont™ Tyvek® Supro is a fire retardant synthetic underlay recommended for use as a self-supporting roof underlay. It is made by laminating a spun-bonded high density polyethylene (HDPE) to a non-woven polypropylene sheet providing a strong weather resistant barrier with excellent water vapour permeability and UV resistance.
DuPont™ Tyvek® Supro Plus has an integrated tape system for ease of in-situ edge sealing.
