Batt / Basic
Annual Savings from Proper Insulation: $0 (based on 1500 ft² rambler with $250/mo utilities)
Batting is a fiberglass blanket that comes in various densities, widths, and lengths and is cut to fit the space in the framing of walls and ceilings. It is typically used in entry-level homes and at less-than-optimal levels.
Blown Fiberglass / Better
Annual Savings from Proper Insulation: $600 (20% savings) (based on 1500 ft² rambler with $250/mo utilities)
Blown-in insulation, using either cellulose or fiberglass, is applied to frame cavities using compressed air. This application allows the insulation to completely fill in all nooks and crannies whereas batt insulation may allow energy loss.
Closed-Cell Spray Foam / Best
Annual Savings from Proper Insulation: $1,200 (40% savings) (based on 1500 ft² rambler with $250/mo utilities)
SPF, Closed-Cell Foam is the most advanced insulation material. The high-density foam is sprayed onto surfaces and hardens immediately to form a seamless bond with building components and completely seals the building envelope to create a structurally sound, uniform, air-infiltration barrier that also blocks moisture (no mold or rot), bugs, rodents, dirt, allergens, and noise. Foam is most commonly used in conjunction with batt and/or blown-in insulation to provide an optimal solution that can save homeowners up to 40% on their energy bills, ensuring a quick return on the investment and $1,000s in savings.
