This 2-in-1 Hybrid Modified Bitumen Roofing Membrane is Resilient and Long-Lasting

Sika Corporation’s Roofing & Waterproofing Team launches SikaShield HB79, a 2-in-1 hybrid modified bitumen membrane that combines APAO (a premium type of APP polymer) with SBS asphaltic membrane technologies to produce a resilient and longer-lasting modified bitumen membrane solution. The membrane is ideal for buildings in locations with seasonal climate and temperature changes, as well as buildings with heavy foot traffic during and after installation.

The APAO top layer exhibits heat resistance and durability, while the SBS bottom layer provides increased elongation, cold weather flexibility, and a secure bond to the substrate. SikaShield HB79 is reinforced with both polyester and glass fiber for increased strength, elongation, shear/tear resistance, and dimensional stability.
