Features and Benefits of Spray Polyurethane Foam

Recently, we had an opportunity to have Pete Corle from THOMCO Inc., a Dow representative come in and demonstrate how to install Dow's Froth Pack Spray Polyurethane Foam insulation in our 1903 building.

Sprayed Polyurethane Foam, or commonly know as SPF, consists of two liquid components, isocyanate and polyol resin are mixed together, usually at 1:1 ratio, creating polyurethane foam.

Spray Polyurethane Foam is a chemically cured versatile material that provides proven solutions to a great range of challenges in the construction industries including filling in of cavities, penetrations, and cracks.

Some benefits of SPF include:
Environmentally friendly.
Contains no formaldehyde or other ozone depleting chemicals
Expands 20-30 times its liquid state.
Quick cure.
Air sealing.
Insulating.
Sound dampening.
Structural stabilization.
Has high R-value per inch (typically 5.8 - 6.8 per inch)
Helps control moisture and condensation
Reduces convective currents in walls and attics

In addition to the benefits listed above, a Class-A rating (flame spread of 25 or less) allows its use in a wide range of industrial, commercial, institutional and residential applications in the United States. SPF can be left exposed in non-fire-resistant rated roof/wall junctures per National Fire Protection Association testing.
