By installing the proper insulation for your home, you can reduce your carbon footprint while keeping your home comfortable. When insulation is used between drywall and flooring, it can help soundproof rooms. If the heating and cooling system in a home is constantly running, it can signify that the insulation isn’t performing as it should. If the indoor temperature changes drastically once the furnace or air conditioning unit turns off, the insulation may be to blame. Professional insulation contractors and some handyman services install insulation.
Foam Board
Some people maintain that fiberglass is hazardous to their health and opt for an eco-friendly alternative such as old denim, cork, sheep’s wool, or recycled plastic. An insulation professional will tell you what kind of insulation will work the best in your home. Fiberglass insulation has an R-value of 2 to 2.5 per inch of depth. It comes in rolls or batts, and it’s the most economical form of insulation. While it’s made primarily of fiberglass, it also can contain plastic fibers, mineral wool, or natural fibers.

However, some types of home insulation should only be installed by a professional. Batting and blown-in insulation are projects that can be accomplished by homeowners, while foam board and spray insulation are more commonly handled by professionals. Wood fiber insulation is used to make rigid boards that insulate ceilings or interior walls. The wood fiber is formed into large, heavy boards and can only be installed on flat surfaces.
DIY Attic Insulation Cost vs. Hiring a Professional
This type of insulation is made of liquid polyurethane and is sprayed into cavities of walls where it expands and hardens into a solid, thick, foam. This type of insulation is much thinner than blanket insulation but is one of the most efficient types, by thickness, on the market. The average cost of foam board insulation is between $2.40 and $3.75 per square foot.
If using insulation other than XPS rigid foam or spray foam, consider adding some sort of vapor barrier as well. To determine how well your walls are insulated, you can cut holes in the drywall or use a thermal imaging camera. Blown-in fiberglass or cellulose insulation and spray foam are common choices for wall cavities. They can be used in conjunction with foam board sheathing on the exterior. Insulating interior walls can help with soundproofing and confining space heating to certain areas of the home.
Batt Insulation
One of the most common materials used for insulation, fiberglass is affordable and popular. It is most commonly used either in batts or as loose-fill and can be used in wall cavities and between floors when installed during new construction or to-the-bones renovation. The median cost of fiberglass insulation is from $0.40 to $1.50 per square foot.

5 Things to Know About Adding Central Air
Foam boards are made from polystyrene, polyisocyanurate, and polyurethane materials. These boards provide a high level of insulation for a thinner board. The boards can be used on the interior and exterior walls, but they need to be coated with approved materials for fire safety. Most insulation eventually loses its R-value and will need replacement. Replacing insulation costs between $2 and $7 per square foot for fiberglass and most blown-in insulation.
This creates a conditioned space that you can then convert into a living space. Most attic conversions cost $40,000 and you can often bundle the price in with new roofing. The cost of a single roll of insulation varies according to its R-value. Insulation comes in standard-sized rolls between 17.5 feet and 80 feet.
That’s partly because these machines do take some amount of skill to operate. In addition, insulation professionals know how to cover the tiny spaces, which is one of the bigger benefits of these types of insulation. Replacing insulation costs $2 to $7 per square foot for most blown in and fiberglass. Spray foam insulation isn’t completely removable, while rigid foam boards are usually the easiest to take out of your home. Crawl space insulation costs $1.00 to $4.50 per square foot installed or $500 to $3,700, depending on the insulation type. Combining rim joist and under-floor insulation is best for vented crawl spaces, while insulating the walls and rim joist is better for unvented areas.
It costs between $1 and $5 per square foot for insulation, depending on the type. A 1,500-square-foot home could cost between $1,500 and $7,500 to insulate. Insulation replacement costs $2 to $8 per square foot, including old insulation removal. Consider replacing insulation immediately if the home experiences water, fire, or pest damage. Damaged or wet insulation loses its R-value, becomes ineffective, and often leads to mold growth. There are four common types of home insulation, each with different costs and advantages.
You can also have spray foam or batting placed inside the attic along the rafters. The closed-cell insulation cost of a SIPs panel runs $7 to $12 per square foot. A SIPs panel is essentially a thick piece of rigid foam board between two sheets of plywood or OSB and designed to carry weight. Prices can differ from the national average due to the type of insulation, project size, home area, labor prices, equipment, site preparation, and cleanup. Radiant barrier installation costs $0.30 to $2.00 per square foot installed, depending on the type, attic size, and installation location.
