Elastomeric bitumen weldable waterproofing membrane, coated with mineral slate
Reinforced with glass vail and aluminium foil. Protected by a thermo-fusible film underneath, with a mineral slate coating on top. Can be used as a vapour barrier and temporary waterproofing that can be exposed to UV rays for several months, and for as a vapour barrier in bonded flat roof systems – the rough surface provides for excellent adhesion to the adhesive used to bond the thermal insulation panels.
