Conditioned Attics

The best way to insulate and air seal an attic.

Building Energy Codes Resource Center – Conditioned Attics

Building Envelope

The true performance of your building envelope can not be measured with the R-value of the insulation alone, but must also consider air movement, moisture control, health, safety, durability, comfort, and energy efficiency.

Spray Polyurethane Foam Energy Savings Benefits

1. Has high R-value per inch (open-cell 3.5 per inch and closed-cell 6.0 per inch)
2. Eliminates air infiltration
3. Helps control moisture and condensation
4. Reduces convective currents in walls and attics
5. Eliminates wind washing
6. Effective at low and high temperatures

Heat Transfer

1. Conduction
2. Radiation
3. Convection Currents
4. Infiltration (Wind Pressure)
5. Intrusion (Wind Wash)
6. Moisture Accumulation (Humidity, Dew, and Frost
