VB EXTREME SA

VB Synthetics Extreme SA is a highly engineered Self Adhered Peel & Stick synthetic roofing underlayment designed for sloped roofs.

The adhesive layer is made from the advanced SBS Modified Bitumen based adhesive which performs extremely well in high as well as low temperatures and gives excellent adhesion to the primary roofing surface whether it is plywood or metal. The temperature performance range for VB Synthetics Extreme SA is -40° F to 260° F (-40° C to 126° C). It has a split release liner with silicone coating on both sides which helps in easier installation.

VB Extreme SA has a light gray top layer which provides for a cooler working surface. VB Extreme’s SUREGRIP high traction walking surface permits easier steep slope walk-ability, even during high condensation or moisture on the surface.
