The Imperflex SA2 is a two-square self-adhered base sheet for the popular SBS-polymer modified bitumen roofing system. Designed in response to contractor requests, the SA2 offers the same installation efficiency as the original 1.5 square version, now in a conveniently larger size. Ideal for roofs with slopes unsuitable for shingles, tile or metal, the system provides a reliable, self-adhered solution. The original 1.5 square option remains available for those preferring a thicker base sheet.
