Fatrafol 807v
A PVP-P based waterproof roofing membrane with underlay of a non-woven PES-textile (mass per unit area – 120g/m2). It is resistant to UV radiation and can be exposed to the direct weathering influences.
Fatrafol 807v is a PVP-P based waterproof roofing membrane with underlay of a non-woven PES-textile (mass per unit area – 120g/m2). It is resistant to UV radiation and can be exposed to the direct weathering influences. Fatrafol 807 has one edge of the sheet without non-woven textile due to enable a longitudinal band joining.
Fatrafol 807v is identified for adhesion systems. The membrane can be adhered directly onto a construction of a roofing mantle, which fulfils requirements for flatness (Fibre-cement, vibrates concrete, etc), possibly onto a suitable waterproof layer beginning treated by heat. The expansion polyurethane adhesives which are especially identified for cementing can be applied. The membrane is unsuitable for adhesion onto bitumen surfaces and for mechanical anchoring. It is necessary to apply a homogenous sheet Fatrafol 804 due to detail working.
Application
The laying of Fatrafol 807v can be made by specialised and for this purpose trained firms at the constructions. The membrane is applied under conformity with fundamentals being set and described in a Construction and Technologic Instruction of the producer, being valid in the time of waterproofing. The membrane must be adhered to a stable part of the substrate/coating by sticking (polyurethane adhesives). The membrane is mutually jointed by welding of hot air. The laying and jointing can be carried out in temperatures up to -5 degrees celsius.
