Self-sealing around the nail shank over a solid surface (tested at the Fraunhofer Institute for Building Physics).

Technology
Polyester fleece with special coating

Security
Polyester is a very weather-resistant material that has excellent resistance to UV radiation and is temperature-resistant up to 120 °C. The special coating is non-slip and can be attached securely.

Saves time and money
