Exposed roofing membrane W-S Top
The W-S Top exposed roofing membrane is a UV-resistant, waterproof membrane made from multiple layers of thermoplastic polyolefins and a polymer fiber base, providing excellent adhesion to cementitious materials such as C2S1 tile adhesive. Suitable for installations requiring a weather-exposed waterproofing membrane.
Manufactured in a highly reflective white color in accordance with the cool-roof standard.
Features That Set the W-S Top Membrane Apart
W-S TOP stands out for combining waterproofing, outdoor durability, and energy efficiency in a single membrane. Its synthetic TPO composition and multilayer structure provide flexibility, stability, and high mechanical performance, while its highly reflective white finish helps reduce heat absorption on the roof. It is designed for non-trafficable flat roofs where an exposed, durable, and weather-resistant solution is needed, featuring an adhered installation and various joint sealing options to ensure continuous and reliable waterproofing.
