The Duro-Last roofing system membrane is a proprietary
thermoplastic formulation consisting of resins and
plasticizers, stabilizers, biocides, flame retardants and
U.V. absorbents. A weft-insertion knitted scrim that is
laminated between two layers of film gives the membrane its
strength and durability. The Duro-Last membrane is available
in white, tan or gray.
Duro-Last has met or exceeded all major fire and wind code
requirements, and regional approvals as necessary throughout
the country. These certifications reinforce Duro-Last’s
leadership in providing the consistent, watertight integrity
that building owners expect.
