Membrane for High-Performance Roofs

VaporDry SA from Benjamin Obdyke is a self-adhered, vapor-permeable roofing membrane. According to the manufacturer, a combination of a permeable trilaminate underlayment and acrylic adhesive helps maximize a roof’s drying potential. The membrane is approved for use with all roofing types with a pitch 3:12 or greater, and the slip-resistant surface meets ASTM D1970 testing. The continuous acrylic adhesive reportedly self-seals around roofing fasteners, allowing the membrane to also serve as an air-control layer. benjaminobdyke.com
