Metalflex SBS Series: Metalflex SBS membranes are manufactured with a top surface of embossed aluminum foil that is laminated during production. Metalflex SBS utilizes the time-proven waterproofing characteristics of SBS-modified asphalt and the protective qualities and reflectivity of aluminum foil. The aluminum surface offers exceptional reflectivity (Initial 89% ASTM C-1549) and also qualifies the assembly for a Class A fire rating with no slope restriction, which cannot be achieved with single-ply and asphalt-based roofing systems. The system is also listed with F.M. (Factory Mutual) to meet I-90 wind uplift and meets ASTM D6298 standards for SBS modified bitumen membranes with foil surfacing. The majority of single-ply and modified asphalt systems have a fire rating limited to a slope of 2:12. The embossed aluminum foil offers exceptional spread of flame resistance, which qualifies metalflex SBS for a Class A fire rating with no slope restriction. This makes it ideal for projects with a barrel roof or for areas with slopes greater than 2:12. Whether it's energy efficient aluminum or bright Polar White surfacing with factory-applied paint finish, metalflex SBS foil-faced surface lends a dramatic look to any project. Compared with single-ply membranes that are applied in one layer of 40–80 mils thickness, metalflex SBS systems are applied in 2–3-ply applications ranging in thickness from 220 mils to 300 mils. The redundancy of multiple layers reduces chances of workmanship error and increases ability of the roofing system to withstand traffic and numerous penetrations.. Metalflex SBS system consists of a base, ply and cap membrane (over wood and light weight concrete), and 2-ply over insulated substrate. The system weighs 175–225 lbs/ 100 square feet depending on the warranty duration. Metalflex SBS system has been marketed for more than 15 years with an excellent track record and has been applied on various projects throughout the country. Surfacing Metalflex SBS is available in two grades, plain aluminum and colored aluminum (white and beige). Custom colors available on request—contact us for minimum run and lead-time. Application Metalflex SBS system is applied via heat welding. The heat welded application eliminates any fumes / odors associated with the application of the membrane. Warranty Application performed by our network of “Eligible Contractors” qualifies for “Material and Workmanship” guarantee (10–15 years). As a condition of this guarantee, we conduct inspections during the application, and a final inspection is conducted to ensure compliance with specifications.
