Why Spray Foam

  • Environmental Design

    Each year, commercial buildings spend over $100 million in energy costs with around 30% of the energy used being wasted. Leading architectural firms have the power to shape a sustainable future through
    energy-efficient, sustainable designs and spray foam.

  • Spray Foam Insulation vs traditional

    Imagine a draft free energy-efficient home. Spray foam expands up to 100 times its original size to fill every corner of a building’s envelope for thermal insulation and air sealing. With traditional insulation, spaces and gaps in homes that aren’t filled can leak enough air everyday to fill two air blimps!
