High-Performance Bituminous Roofing Underlayment
Sika Index Rollbase V 2kg is a premium APP modified bituminous membrane designed for versatility and durability. Specifically engineered to be mechanically fastened, it serves as an essential base layer for torch-on applications where direct adhesion to the substrate—such as timber or metal—is not possible.
Key Features and Benefits
The underside of the membrane features an absorbent nonwoven polyester fabric. This unique design effectively traps residual humidity from wooden substrates or existing waterproofing layers, preventing moisture damage. Reinforced with fiberglass, the Rollbase V ensures exceptional dimensional stability.
