Roof membranes

SYSTEMATIC SAFETY AND ENERGY EFFICIENCY

CaTop M 170 + G SK is a diffusion permeable, universally applicable and highly tear-resistant sarking membrane, in accordance DIN EN 13859-1, equipped with an integrated self-adhesive strip. Also available without adhesive strip, as CaTop M 170 + G. The multi-layered membrane consists of polypropylene woven material, a medium reinforced fabric and an inner-lying functional membrane. The special design gives it an exceptionally high tear resistance and good rainwater tightness, while simultaneously having a high water-vapour permeability.

When working with the material it is necessary to observe the applicable standards, the generally recognized rules of manufacturers as well as the CaPlast laying information. Subject to technical modifications.



Fields of application

• Sarking (UDB-A) and underlay (USB-A)
• Temporary roof covering
• Formwork membrane
• Rear ventilated and non rear ventilated constructions
• Renovation work and new constructions

Benefits

• Integrated self adhesive strips
• Approved sealing against driving rain
• Very good tear resistance and nail tear resistance
• High diffusion permeability
• Impervious to wind, water and driving rain
• Secure laying and easy handling
