WestWood’s PMMA flashing systems deliver reliable, fully reinforced waterproofing for the most complex transitions on a project, from parapets and curbs to penetrations, terminations, and irregular geometries. Unlike sheet-based materials that rely on cuts, seams, or adhesives, PMMA is applied as a fully reinforced liquid and cures into a seamless, monolithic membrane that bonds directly to the substrate. The result is a durable, watertight flashing solution that integrates effortlessly with WestWood field membranes, WePly SBS systems, and a wide range of roofing and waterproofing assemblies, ensuring long-term protection where it matters most.

WestWood’s hybrid assemblies offer numerous configurations to meet the needs of your structure, offering durability, flexibility, and long-term protection tailored to the demands of modern roofing and waterproofing.
