BITUMAT V 12 FORATO is a bituminous foil consisting in a pierced glass tissue reinforcement (holes diameter 40 mm) impregnated in oxidized bitumen and surfaced on both sides with finely granulated non-adherent mineral material.
- It allows the membranes to be laid semi-independently, reducing the tension on them in the presence of movements from the underlying structure and hence reducing the risks of joints detaching and corrugation
- It creates a vapor flow layer, reducing the risk of condensation in the insulation and renders the ventilation vents more effective
- It has reduced thickness
- Vapor management in flat roofs
- Laying of membranes semi-independently in flat roofs
