Benefits of Closed-Cell Spray Polyurethane Foam (SPF)

SPF reduces energy use in the following ways:

• Has high R-value per inch - (open-cell 3.5 per inch and closed-cell 6.0 per inch)
• Eliminates air infiltration
• Helps control moisture and condensation
• Reduces convective currents in walls and attics
• Eliminates wind washing
• Effective at low and high temperatures
• Provides the correct environment so that the ventilation system performs more efficiently

COMFORT:

• SPF reduces drafts and increases comfort.
• SPF helps maintain a comfortable, constant, temperature throughout the building, from room to room and floor to floor.

HEALTH:

• SPF assists in improving indoor air quality.
• SPF reduces the infiltration of outside air pollutants and soil gases. SPF can reduce moisture condensation and mold growth within the building walls and roof.

VALUE:

• Excellent insulation efficiency of SPF can reduce heating and cooling usage dramatically.
• HVAC equipment can be down-sized, thereby reducing construction costs.
• SPF will not sag or settle. SPF can eliminate the need for separate housewrap and vapor retarders.

ENVIRONMENT:

• SPF helps conserve energy, reducing CO2 emissions.
• SPF contributes LEED credits for sustainable, green construction. SPF can help reduce structural damage caused by high winds. SPF contains no formaldehyde or ozone depleting substances.
