ValuWeld S

ValuWeld S is used as a cap or base sheet in APP multi-ply roofing systems.

Premium APP (Atactic Polypropylene) Polymer and Asphalt Blend: Provides an extremely durable sheet with excellent weathering characteristics, flexibility and dimensional stability for ease of handling and quick installations.

Polyester Reinforcement Mat: Offers good tensile strength, toughness and puncture resistance and can accommodate stresses created by typical rooftop expansion and contraction forces.

Surfacing: Fine mineral parting agent on the top of the sheet. A polyolefin burn-off film on the bottom side enables the product to be applied using heat-welding techniques
