Technical Info
HEATLOK is a high performance Rigid Foam Insulation that is spray- applied exclusively by Approved Applicators under the employ of Authorized Contractors, in accordance with CAN/ULC S705.2 (Standard for Thermal Insulation Spray Applied Rigid Polyurethane Foam, medium density- Applicator’s responsibilities).
The high closed cell content and the monolithic application of the rigid spray foam makes it appropriate for use on exterior walls of residential structures and high and low-rise buildings. A number of studies conducted by the United States Department of Energy shows that 40% of energy loss from residential construction is due to air leakage. Rigid spray foam exhibits a very low air leakage and can be classified as a Type 2 vapor retarder. Controlling moisture and the prevention of dew point within wall assemblies is necessary for the prevention of premature decay and the growth of mold and mildew. Rigid spray foam applied on the exterior of buildings can assume the role of both the drain plane and the rain screen providing an excellent water resistive barrier.
