Prefabricated bituminous membrane
Pre-fabricated waterproofing membrane made of distilled bitumen and plastomeric polymers (APP) having a woven non woven single strand composite polyester reinforcement, which provide the membrane with good mechanical characteristics and excellent dimensional stability.
The versions V & VA have a fibre glass reinforcement, with excellent dimensional stability.
The versions VA & PA are self-protected on the upper face with mineral slates which reduce superficial heat absorption improving the durability of the membrane.
The self-protected versions have a side selvedge of 10 cm and upon request a head selvedge of 15 cm, to improve adhesion between the sheets.
