New roof system is versatile

Johns Manville has added a new SeamFree® PMMA Liquid Membrane roof system to its liquid roofing line.

The new roof system includes a portfolio of PMMA-based products that combine to form a membrane system that can be used in many applications, including plaza decks, garden roof systems, roof systems with many penetrations, and irregularly shaped or small roof systems.

The PMMA Liquid Membrane roof system reportedly offers excellent adhesion to a variety of substrates, including metal, wood, plastic, concrete and asphalt; can be applied in temperatures ranging from 23 F to 95 F; is rainproof within 30 minutes and fully cured in three hours; and is resistant to chemicals, ultraviolet rays, ponding water and root penetration.
