Spray Polyurethane Foam Insulation can be used in two common ways to insulate your attic space and protect your home from in climate weather and moisture related damages – Vented and Non-Vented Attic spaces. 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. 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.
