Insulation plays a big role in keeping your home warm in winter and cool in summer. Properly insulating your attic and properly air-sealing your home helps prevent warm indoor air from escaping into the attic and cold outside air from entering your home, making sure that your heating and cooling system has to work less hard to keep you comfortable.
The type of spray foam insulation material used to insulate your attic depends on several factors, including local weather and the size and layout of your home. Your professional should make a complete assessment of your home’s needs and recommend the right materials for your situation.
Attic insulation typically is made from fiberglass, cellulose, or foam. Blown-in insulation, or loose-fill, is installed with a blowing machine that sprays small particles of fiberglass, cellulose, or mineral wool into your attic to fill gaps and cover surfaces evenly. It provides good sound insulation and is often made of recycled materials. However, blown-in insulation can settle over time, decreasing its R-value and may require additional top-ups. It can also absorb moisture, which increases the risk of mold and mildew.

Fiberglass batt insulation comes in blankets that can be affixed to attic walls. It is inexpensive and offers good R-value per inch. It is also available as an eco-friendly option, made of recycled denim fibers and treated with borate for fire resistance and pest control. It can be uncomfortable to handle and may not fit well into awkward spaces. Rigid foam insulation, or foam boards, is a thick board made of polystyrene, polyisocyanurate (polyiso), or polyurethane that can be cut to fit and installed against the structural elements of your attic. It has a high R-value and reduces heat conduction through the attic floor and studs.
