Products / Parapro PMMA Roof Membrane and Flashing System

Parapro is Siplast's PMMA (polymethyl methacrylate) liquid-applied line. Parapro Roof Membrane Resin and Parapro Flashing Resin are multi-component, fast-curing, flexible PMMA resins that, when catalyzed, are combined with polyester fleece (Pro Fleece) to form a monolithic, reinforced roof membrane or flashing membrane. The roof membrane system is for exposed roofing and waterproofing applications not subject to pedestrian or vehicular traffic, while the flashing resin is used for flashing details and repairs with a variety of Siplast roofing and waterproofing systems. Siplast lists the resins in summer and winter grades, in white or light gray, with a 30-minute rainproof time and 2-hour walkability, and a VOC content under 25 g/L when catalyzed.
