SPF (Sprayed polyurethane foam) has an R-value of approximately R-6 per inch, which
allows it to provide a higher thermal resistance with less material. A typical batt of traditional insulation only provides an R-value or 2 per inch. Because spray foam insulation provides more thermal resistance with less material than traditional insulation products, energy savings of 30% or more is achieved. Typically, the investment of spray foam insulation is returned in less than five years through the savings in energy costs.
Spray foam insulation has many benefits including:
Complete Air Sealing
According to studies, air infiltration is responsible for up to 40% of a buildings energy loss. Although batt insulation is an effective way to retain heat in a home or building small gaps still exist. Spray foam insulation completely seals areas where air infiltration can occur, as it creates a tight seal from end to end and top to bottom of a wall cavity. This makes SPF (spray polyurethane foam) far more effective as it totally eliminates any air infiltration.
