Increasing your home insulation is one of the easiest ways of improving your home’s comfort through the long Michigan winter. The effectiveness of home insulation is measured in terms of R-value, or heat flow resistance. According to the Michigan Department of Energy, Michigan homes should be insulated to an R-value of 49 in the attic, 18 to 22 in the walls, and 25 in floors.
Before spending a large amount of time and money on insulating your home, take some time learn about the types of insulation and where they are most appropriately used.
- Fiberglass, rock wool and natural fiber insulation batts are used between wall studs, ceiling and floor joists when walls are being constructed or in unfinished spaces like attics and basements. The most common fiberglass batts range in R-value from 2.9 to 3.8 per inch of thickness.
- Loose cellulose, fiberglass or rock wool is commonly blown into unfinished and hard-to-reach spaces where it will be undisturbed, like cavities between walls or in unfinished attics. Depending on the material, it has an R-value from 2.2 to 3.8 per inch-deep layer.
- Rigid polystyrene board insulation panels are often used on home exteriors, under siding, and on interior basement walls that are then finished. They offer a high R-value for their thickness, according to the Department of Energy’s Energy Savers program.
- Polyurethane spray foam is a material that expands to fill spaces, sealing air leaks as well as insulating. It has a high R-value per square inch and does not absorb water, an issue with other types of insulation. It is usually professionally applied in wall cavities and the underside of floors and roofs.
