At St. Croix Insulation we use the industry's top products and technology.

Below you will find information about one of our top spray foam products, Icynene, the industry's leading soft foam insulation and air barrier system. Icynene has become the industry standard for providing maximum building envelope performance. Icynene's pour and spray formulations represent a breakthrough in the science of moisture and thermal management.

Icynene minimizes air leakage for increased energy efficiency. It creates a healthier indoor environment, reduces airborne sounds and offers greater design freedom. Icynene maintains its performance with no loss in R-value over time. It does not shrink, sag or settle. Icynene adheres to most construction materials and is the perfect insulation for walls, attics, ceilings and floors.

Icynene Spray Formula
Applied as a liquid, Icynene® expands to 100 times its volume in seconds to fill every crack and crevice while remaining flexible so that the integrity of the building envelope seal remains intact over time. Icynene's spray formula has an R-value (link to 101) of 3.6 per inch. It acts as a complete insulation and air barrier to minimize air leakage and seal the building envelope for optimal airtightness.
