AlphaRexx is a five-layer roof membrane with a low level of vapour permeability, designated for application as a waterproof layer for initial coverage of diagonal roofs with full boarding or without boarding. AlphaRexx is strong and solid - a modern alternative for the traditional bitumen layer. AlphaRexx has long service period and very good resistance to UV radiation. It does not harden in the ageing process and therefore does not crush under the roof tiles.
Adhesive, sealing AlphaProxx tape can be used under counter battens. Nails and fastening screws may be used through that tape.
AlphaRexx can be applied during construction even for 24 months without the final coating. It is very durable and easy to place.
