SPRAYED POLYURETHANE FOAM INSULATION

SPRAYED POLYURETHANE FOAM INSULATIONReviewed by Roco on Dec 29Rating: 4.0

Sprayed polyurethane foam (SPF) insulation systems are self-adhering, two-component materials, that are applied directly to roof decks, and may be used as an insulation and air barrier when applied to the underside of a roof deck, or it may be used in combination with one of several types of protective coatings as the primary roof covering. SPF insulation is available as closed cell or open cell in varying levels of vapor permeability so coordination with the primary roof covering is required to prevent moisture problems. Refer to the SPF roofing section below for additional information on its use as a primary roof covering.
