A silicone air-barrier system is a suite of products that work together to protect the building envelope. For new projects and renovations, the low-VOC formula is appropriate for green construction. The system includes DefendAir 200 that provides primerless adhesion to most substrates; Silicone Transition System rubber strips and corners to form a continuous, airtight transition; and the company’s silicone sealants, including 791 weatherproofing sealant, used in through-wall flashing applications and to seal penetrations.
