1. The Henkel Polybit AL Hosan Roofling Felt Membrane is a multi-layer, heat and water-resistant membrane that provides superior protection to roofs against extreme weather conditions. It is made from a combination of high-grade polymeric bitumen and aluminum foil, making it highly durable and resistant to extreme temperatures. The membrane also provides reliable protection from rain, snow, hail and strong winds.
2. The membrane is easy to install and can be applied in either a single layer or multiple layers. The single-layer application is suitable for flat roofs while the multi-layer application is ideal for sloped roofs. The membrane is also lightweight and flexible, making it easy to handle and install.
3. The membrane can also be used to repair existing roofing systems, providing a quick and easy solution for any roofing problem. It is also resistant to UV rays, ensuring that it does not degrade over time. The membrane is also highly resistant to rot and fungus, providing long-term protection to the roof.
4. The membrane is also highly cost-effective, providing a cost-efficient solution for roofing projects. It is also environmentally friendly, as it does not contain any harmful chemicals or toxins.
