KÖSTER TPO membranes are made of flexible polyolefin. A glass fiber mesh is embedded in the center of the membrane to ensure exceptionally high dimensional stability and puncture resistance. They provide high reliability and are distinguished by quick and cost-effective installation. KÖSTER TPO membranes are UV-resistant, resistant to aging and microorganisms, and can be applied directly over old bitumen membranes.
KÖSTER TPO F membranes additionally feature a polyester fleece backing for full-surface adhesive installation.
