Owens Corning. Ideal for home performance improvement projects, the EnergyComplete whole-home insulation and air sealing system is GreenGuard certified for indoor air quality. For existing homes, EnergyComplete can be installed in attics, basements, crawlspaces, or in the walls for additions or down-to-the-studs remodels. Installed in two steps, the system uses a foam-based sealant to reduce air leakage and the maker’s familiar Pink Fiberglas insulation for thermal performance. Flexible Seal Technology helps reduce air infiltration by up to 70%, the maker says. www.owenscorning.com.
