Bituminous welding membranes with a schist aggregate layer
The IZOELAST REFLEX P5 DIN PLUS bitumen waterproofing membrane is used as the finishing layer in two- or multi-layer waterproofing of green flat roofs. It can also be used as a membrane for the restoration (resurfacing) of flat roofs. The membrane is protected against UV radiation by a layer of schist aggregate on the top side and by a fusible film on the bottom side. The membrane is installed by welding with a 10 cm overlap. The product complies with SIST EN 13707 (finishing layer) and SIST 1031.

To protect the bitumen membranes (reflex membranes), schist aggregate is used, the colour shade of which may vary slightly from one production batch to another. This does not affect the product functionality.
