Sika Corporation’s Roofing & Waterproofing team has launched SikaShield branded Modified Bitumen roofing products and a new “Hybrid” membrane into the U.S. market. SikaShield, a brand trusted in Europe and other parts of the world for its unmatched longevity and durability is ready to shake up the U.S. mod. bit. roofing market with its one-of-a-kind, innovative “hybrid” membrane, SikaShield HB79.
SikaShield HB79 is a 2-in-1 “hybrid” modified bitumen membrane that combines APAO (a premium type of APP polymer) and SBS asphaltic membrane technologies to produce a more resilient and longer-lasting modified bitumen membrane solution. This makes the membrane perfect for buildings in locations with seasonal climate and temperature changes as well as buildings with heavy foot traffic during and after installation.
APAO polymer is compatible with SBS making the innovative combination possible. “Combining APP and SBS is the next evolution in modified bitumen membrane, says Juliana Grippa, National Manager – Bituminous Systems. “The combination of both polymers into one sheet helps form what is basically a “super membrane.” The APAO top layer exhibits excellent heat resistance and durability, while the SBS bottom layer exhibits 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.
