Knauf.The KISS system combines the manufacturer's EcoBatt insulation or Jet Stream blow-in insulation and a new water-based elastomeric sealant, EcoSeal. The sealant dries to a flexible tough film, creating an air barrier at the home's seams. It contains no solvents and less than 0.3% VOCs, and it requires no CFCs or HCFCs for manufacturing or installation. According to the firm, EcoSeal has an STC rating higher than foam, is Class A rated for fire and smoke, applies in temperatures from 20 degrees to 115 degrees F, and cleans up with water. www.knaufinsulation.us.
