WeatherShield TPO Waterproofing Membrane
Product Overview
Our TPO roofing membrane is a premium thermoplastic polyolefin sheet designed for superior long-term waterproofing in commercial and residential roofing projects. Engineered for exceptional resistance to UV radiation, ozone, and chemical exposure, this single-ply roofing solution remains flexible in cold weather while resisting grease and bacterial growth.
Featuring a heat-weldable seam technology, it ensures strong, watertight seams that are stronger than the membrane itself. With high reflectivity, our TPO waterproofing membrane helps reduce building energy consumption, contributing to LEED certification points. Available in multiple thicknesses (1.2mm, 1.5mm, 2.0mm) and widths up to 3.05m to minimize on-site seaming.
