PostSubject: Spray Foam Insulation in the Attic Floor    Fri Aug 11, 2017 10:17 pm

The method of use for spray foam in the attic is often dictated by the building science and design principles your architect and/or builder subscribes to. In a traditional vented attic, insulation is used on the attic floor to insulate the ceiling from the seasonal heat and/or cold. Spray foam is used where traditional fiberglass batts, or cellulose is used; between the floor joists. The rest if the attic is left un-insulated and highly vented through gable, soffit, and ridge vents in the roof structure.

The traditional practice of insulating the underside of the roof in the attic has raised much debate in the building industry because ‘standard’ roofing and design techniques call for the attic to be ventilated in order to reduce moisture problems and heat build-up in the hot summer months.

However, a vented attic situation it will become approximately 130-degrees in the summer. There’s no reason for your air-conditioning and vent-ductwork to have to work in that type of severe conditions. There is also opportunity for moisture to form due to condensation on these appliances.
