Spray Foam
Seal gaps and prevent air leakage with spray foam insulation. It has one of the highest R-values in the industry. Used together with fiberglass batts, it can form a complete, worry-free barrier that adds structural integrity while keeping out pollutants and allergens.
Spray foam has become increasingly popular due to its excellent thermal and air barrier properties. Spray foam is available in two primary types: open cell and closed cell.
- Open cell foam is spongy and offers excellent air barrier and R-Value per inch. The expansion rate is typically 180:1. Open cell does not provide a vapor or moisture barrier. It is lower cost as compared to closed cell, making it a good choice for above grade wall applications.
- Closed cell foam is a rigid product, offering the highest R-Value per inch of all insulation products and also boasts thermal, ignition, air, moisture and vapor barrier properties. Expansion rate is typically 30:1. Closed cell is an excellent choice for all wall applications including below grade.
