InsulStar® 1.7 is a 1.7 lb/ft3 density, closed-cell polyurethane foam insulation applied as a liquid to the wall, ceiling, attic or floors. The liquid reacts, expands, and cures in place, forming a fully adhered, seamless insulating and air-blocking membrane that helps seal walls to prevent air penetration and block outside noise pollution. The results are a quieter home and lower energy costs.
The closed-cell structure of InsulStar® 1.7 blocks air movement and has a low permeance, which controls moisture vapor movement, eliminating the need for an additional vapor retarder. When moisture vapor is controlled, condensation will not occur, thus eliminating the water needed to support mold growth. InsulStar® 1.7 is naturally able to inhibit the growth of bacteria and fungus (mold) per the ASTM C1338. The anti-microbial properties do not protect occupants of spaces insulated with InsulStar® 1.7 from the effects of molds, mold spores, or disease organisms that may be present in the environment.
