KÖSTER TPO Membranes are made of flexible polyolefin. A glass fiber mesh is embedded in the middle of the membrane to provide an especially high dimensional stability and resistance against perforation. It offers a high reliability and is characterized by a fast and economical installation. KÖSTER TPO Membranes are UV-stable, resistant to aging, microorganisms, and can be applied directly onto old bitumen membranes.
KÖSTER TPO F Membranes feature an additional polyester fleece backing for a full surface adhesion installation.
