Sprayed Polyurethane Foam: Controlling airflow and water movement

Energy use, indoor air quality (IAQ), comfort, moisture intrusion, and durability are important considerations for design/construction professionals. To create a healthy, energy-efficient living space, a facility must be able to control airflow and water movement through the building envelope. The phrase “build tight, ventilate right” is used by building science experts to express the recommended building approach. One way to help address these concerns is through the use of sprayed polyurethane foam (SPF) insulation or other materials with similar properties.

Achieving safe spray foam insulation applications

Sprayed polyurethane foam (SPF) is gaining global recognition because it provides superior insulating properties by creating a tight building envelope that reduces unwanted air infiltration. Achieving a tight building envelope is the foundation for an energy-efficient building. According to Natural Resources Canada (NRCAN), “air leakage represents 25 to 40 per cent of the heat lost from an older home.” Creating a tight, well-insulated building envelope by insulating and air-sealing with SPF will reduce energy bills significantly when compared to traditionally insulated buildings.
