Elastoflex V 22 is a Styrene-Butadiene-Styrene (SBS) modified bitumen roofing membrane base sheet. This higher quality membrane is reinforced with a high quality fiberglass mat to ensure strength and excellent dimensional stability to the product. Elastoflex V 22 exhibits superior waterproofing and weathering physical properties. The top and bottom surfaces are available in sand or factory applied burn-off film. Application methods include mechanically attached, hot asphalt, heat-welded, or as part of cold-applied system. When the top of membrane is surfaced with film, Elastoflex V 22 can be used as a base sheet in self-adhered systems. Elastoflex V 22 membrane can be used as part of a Polyglass warranted multi-ply system, when combined with Elastoflex V G cap sheets or other approved Polyglass base sheets.
