CM10009
CM10058
CM10105

High-performance torch-on waterproofing membrane for multi-layer applications, with or without insulation. Following project evaluation, may be used for single-layer applications.

The compound used in Dermabit® membranes contains distilled bitumen and the latest generation of technopolymers (APAO) that ensure excellent properties of flexibility, elasticity and adherence as well as making Dermabit extremely resistant to aging.

Product Pluses: Guaranteed by more than 25 years in the field, certified solutions, versatile and reliable at any latitude, extensive thermal operating range (-25°C to +150°C), fast and easy to apply, excellent resistance to UV and aging.

Thanks to the use of reinforcement with a high mass per unit area and continuous non-woven polyester stabilised by means of glass strands, Dermabit Extra guarantees outstanding mechanical performance and dimensional stability (±0.2/0.3%)

Especially designed for large surfaces subject to high thermal stress due to direct sunlight or high temperature build up.

Top finish in silica sand, non-woven polypropylene, natural or coloured slate chips disseminated uniformly and firmly anchored; smooth bottom finish in torched off polyethylene sheets.
