Insulation for Attic Applications
Spray Polyurethane Foam Insulation can be used to insulate your attic space and protect your home from inclement weather and moisture-related damages.
Two common insulation spaces are Vented and Non-Vented Attic spaces.
Vented Attic Space
In a Vented attic, insulation is used on the attic floor to insulate the living space from seasonal heat and/or cold. Spray foam is used where traditional insulation would be; between the floor joists. The rest of the attic (ie: the roof assembly) is left un-insulated and ventilation is incorporated into the gable, soffit, and ridge vents throughout the roof structure.
Non-Vented Attic Space
In a Non-Vented attic, insulation is applied directly to the underside of the roof sheathing to insulate the entire attic from seasonal heat and/or cold. Spray foam is installed between the roof rafters, along the soffit areas, and directly to all exterior surfaces such as gable walls, dormers, etc., to produce an air-tight building envelope.
