Attic insulation costs $2 to $6 per square foot installed, depending on the type, R-value, job size, and complexity. The average cost to insulate an attic is $1,500 to $3,200. Small attic insulation costs start at $700, while insulating large attics costs up to $6,500.
Attic:
The attic stands out as a critical location for insulation, given the natural tendency of heat to rise. Many homes have insulation in the attic to counteract the loss of rising warm air. Spray insulation foam is a common material for attics, followed by batts or blown-in insulation. The average cost of insulating an attic has risen to a range of $2,250 to $9,000.
Roof:
Roof insulation becomes particularly valuable when struggling to retain heat in your home or when converting the attic into a livable space. Attic conversions, though potentially costly, can often be bundled with new roofing, featuring roof insulation or additional insulation for an existing roof. For new construction, professionals can now install rigid foam board insulation beneath the shingles. In existing construction, batting or spray foam can be applied along the rafters. The average cost for roof insulation has to $2,250 to $6,750.
Wall:
Wall insulation, the most common type, is typically installed as mineral wool or fiberglass batting set between the studs. In newly constructed homes, spray foam or rigid board insulation below the exterior house siding may be used. The cost of wall insulation now ranges from $1.25 to $5.00 per square foot.
Home Insulation Cost by Material
Home insulation comes in various materials, each with its own set of advantages and drawbacks. Certain materials are suitable only for specific locations, and some are tailored for new construction rather than insulation additions or replacements. Here are the most prevalent insulators, their common applications, and the average costs.
Fiberglass:
A widely used and affordable insulation material, fiberglass is commonly employed in batts or as loose-fill. It finds application in wall cavities and between floors during new construction or extensive renovations. The median cost of fiberglass insulation has risen to $0.60 to $2.25 per square foot.
Cellulose:
Primarily used as loose-fill, cellulose insulation is blown into existing wall cavities. Often available in a damp spray form, it adheres as it settles into the walls. The cost range for cellulose insulation is from $0.90 to $3.45 per square foot.
Polystyrene:
Polystyrene insulation is utilized to create foam boards or spray foam insulation. Foam boards are applied to cover building exteriors (under roof shingles or siding), while spray foam is used to fill wall cavities or under attic floors. The median cost range of polystyrene has surged to $1.50 to $22.50 per square foot.
Blue Jean:
An eco-friendly and user-friendly insulation alternative, blue jean insulation is designed to replace fiberglass batting and is crafted from recycled blue jeans. Its absence of small glass particles makes it more DIY-friendly. The median cost range of blue jean insulation to $2.25 to $2.63 per square foot.
