Premier Building Systems. Zero-VOC Mastic can be used in lieu of the maker’s traditional mastic when installing its structural insulated panels. Zero-VOC Mastic consists of polymers designed to remain flexible yet provide a tight seal that eliminates water vapor and air infiltration; it resists moisture, dampness, and temperature fluctuations. The mastic is available in 20-ounce sausage packs, which are smaller than traditional mastic packaging and, when empty, compress down to a small puck to reduce jobsite waste. 800.275.7086. www.pbssips.com.
