“WOLFIN M – For high quality, mechanically
fixed roof waterproofing.”

Efficient fixing

Secret composition

Wolfin M roof and waterproofing membrane is produced from Poly-Vinyl-Chloride (PVC-P-BV) through extrusion and in homogeneous throughout.  It is automatically produced in the wished thickness with a glass fibre mesh in the middle. Wolfin M is fire resistant even though non of these fire resistant additives are used furthermore it excels through its bitumen resistance and can be welded either with adhesives or hot air throughout it whole life period.

Unique properties

Diffusion open and bitumen resistant

Wolfin M membranes are diffusion open with a μ-value of 13.000. Moisture in existing roofing layers can be dried out using our refurbishment method which has been confirmed by the Fraunhofer Institute. Wolfin M is resistat againt flux oils, mineral oils, lactic acids, kerosin, etc. Accordingly, Wolfin IB is commonly used there where the chemical radiation high is, due to its chemical resistance. These also include the waterproofing of areas for industrial clients.
