Custom Length 20m TPO Waterproofing Membrane For Building Roofs

Tpo Waterproofing Membrane For Building Roofs

Product Introduction

 TPO waterproof membrane for building roofing is currently the most used TPO category at home and abroad, dominated by fabric-reinforced Type products, with homogeneous Type H membranes used as supporting materials in some complex nodes. It conforms to the national standard GB 2779-2011, has mainstream thicknesses of 1.5mm, 1.8mm and 2.0mm, and mostly widths of 2.0m and 3.05m, with high-reflectivity white as the main surface color. This type of membrane combines the weather resistance of ethylene propylene rubber and the weldability of polypropylene, being a high-performance single-layer waterproof material designed specifically for long-term service of exposed roofs. Some high-end products have passed the B1 grade combustion performance test of GB 8624-2025 standard, and are suitable for roof scenarios of large public buildings such as industrial plants, logistics warehouses, airport terminals, and stadiums.

Purpose and Functions

 Its core function is to provide a complete waterproof barrier various low-slope single-ply roofs, effectively resisting the long-term erosion caused rain, snow, ultraviolet rays and strong wind loads, and solving the pain points of traditional rolls such as easy aging, easy blistering and easy seam leakage. For metal roof renovation scenarios, it can directly cover the original panel to form a composite waterproof system without removing the old roof, greatly reducing construction costs and construction period; For steel structure factory roofs, it can cooperate with fastening systems to disperse the tension caused by wind loads, avoiding the waterproof rolls from being torn strong wind. At the same time, its high-reflective surface feature can reduce the overall temperature of the roof, decrease the thermal expansion contraction deformation of the roof structure, and indirectly extend the service life of the roof sheet.
