FATRAFLEX is a PVC-P profile designed as a substrate/spacer profile for flexible photovoltaic panels installed on roofs with PVC waterproofing membranes. It is made by extruding PVC from reclaimed materials arising from roofing membrane production.
Auxiliary components are an integral part of the waterproofing of every building.
Our accessories contribute to the perfect tightness of the insulation envelope.
The materials are derived from the individual FATRAFOL membrane types, which guarantees their mutual compatibility.
FATRAFLEX is fastened on both sides by hot-air welds to the main waterproofing layer of a PVC-P membrane roof. The strength of the substrate below the waterproofing membrane must match the expected loading. Particularly on roofs with soft thermal insulation, care must be taken not to exceed its permissible compressive load.
FATRAFLEX profile is recommended for installation on roofs with new waterproofing of a membrane at least 1.80 mm thick, which ensures long service life and stability of the whole system. More information on profile application can be found in the Application instructions.
