Product description

Roofing underlayment with two self-adhesive strips

Alfa Rufol Thermo ND SK is a highly vapour permeable sarking membrane with special sealing coat for the installation on insulation material or on the roof boarding. The membrane can be used as underlay for slate roofings. The overlaps may be bonded or laid looselsy, depending on the individual application.

The roofing underlay is used to create a rain-proof roof. Due to its permanent resistance to UV-radiation and weathering, Alfa Rufol Thermo ND SK can be used as temporary roofing or as underlay / sub-membrane with rainproof seams and additional protection against perforations.

For the membrane to fulfill its functions correctly, please always make sure the entire construction of the roof is made according to the current rules of the trade.

Easy handling: Auxiliary lines allow exact overlaps, the self-adhesive strips a windtight and rainproof sealing.
