ProSEAL™ is the most energy efficient closed-cell polyurethane spray foam insulation system available. It is formulated to provide maximum benefits to home and business owners in addition to saving significantly on energy costs. It stops air leakage, reduces noise and blocks dust, pollen and other airborne pollutants. It controls moisture movement to prevent condensation conditions, thereby eliminating the moisture that can lead to mold growth. When applied directly to the roof deck, ProSEAL™ adds structural strength and greatly increases the ability to withstand uplift from high winds.
