Installation is less disruptive. You will hardly know we are there. No loud machinery, no noxious fumes, no potential damage by rain getting in during installation, no messy splatters of tar to clean up, can be installed in less time saving labor cost and intrusion to the home or work space, or classroom.
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 can also be painted. See the General Specifications for details.
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.
Duro-Last has been approved by Factory Mutual as a 1-60,1-90, 1-105, 1-150 and 1-210 roofing system. Duro-Last is also listed by Underwriters Laboratories as a UL Class A material. Evaluation services ICBO and NES have merged to form ICC-ES, which has evaluated Duro-Last for the International Building Code (IBC). The Duro-Last roofing system has been approved by the IBC and by code agency MIAMI-DADE for use in their respective jurisdictions.
