Features:
- 20-year lifespan
- Minimal extra load on roof (specific gravity approx. 1.25kg /m2)
- Wide temperate range (-25°C to +130°C)
- Withstands structure movement (can stretch up to approx 300% without tearing, cracking or splitting)
- Superior waterproofing capabilities compare to conventional EPDM sheets
- Does not deteriorate due to weather, heat, sunlight or oxidation
- Resistant to most acidic & alkaline conditions with a better chemical resistance than alternatives
- Perfect for roofing, wall protection and mining/construction applications
Description:
Metroseal’s EPDM rubber roofing membrane is a high-quality solution offering remarkable elasticity, capable of stretching without tearing or cracking, ensuring long-lasting durability across a range of temperatures.
Installation is straightforward, guaranteeing cost-efficiency and durability. Not only does it prevent leaks, but it also improves insulation and resists moss and algae growth.
Designed to withstand both acidic and alkaline conditions our membrane is a reliable choice for various applications. Its lightweight design minimises the additional roof load, ensuring structural integrity. Compared to traditional materials like asphalt and PVC, it excels in waterproofing power.
It suits diverse applications, including different roofing types, homes, garages, sheds, storage facilities, green roofs, wall protection, mining, construction, and geo-membranes.
Our EPDM Rubber Roofing Membrane complies with industry standards, including ASTM D4637 and ASTM 6134, ensuring top-notch quality. With various dimensions available, you can easily find the right fit for your project.
