Allotting for installation of an HVAC system within the thermal envelope is a key maximize a building’s space and minimize air leakage to the outside. Using spray foam insulation within an unvented attic creates a continuous air barrier and insulation layer that saves energy and money. Spray foam insulation (both open-cell and closed-cell) adds structural strength, sound-dampening qualities, high R-value, and the control of outdoor pollutants for both commercial and residential buildings.
- Assess the advantages of unvented attic assemblies
- Evaluate the effectiveness of spray insulation in commercial and residential unvented attic applications and designs
- Understand and be able to address the moisture and temperature concerns that apply to unvented attic applications
- Analyze the environmental impact of spray foam insulation technology, including minimal global warming potential
