Although it costs more than fiberglass insulation, it has a higher R-value and can eventually lower energy costs.
2. Cellulose Insulation: Newspaper and cardboard recycled materials are used to make cellulose insulation. It offers good soundproofing and fire resistance while being an environmentally friendly option for basement insulation.While it has a lower R-value than spray foam insulation, it is still a good choice for those who prioritize sustainability and eco-friendliness.
3. Mineral Wool Insulation: Mineral wool insulation is a good option for basement insulation because it is made from rock or slag fibers. It offers better soundproofing and fire resistance than fiberglass insulation and has a higher R-value. It is a good option for damp or humid basements because it is also resistant to moisture and mold.

It’s crucial to take into account aspects like price, R-value, moisture resistance, and soundproofing when contrasting fiberglass insulation to other varieties of basement insulation. While fiberglass insulation is a reasonably priced option, other types of insulation might offer better soundproofing and insulation qualities.

R-value of fiberglass insulation in Basement

The ability of insulation to resist heat flow is measured by its R-value. The ability of the insulation to keep heat outside in the summer and inside during the winter increases with increasing R-value. Depending on the density and quality of the material, fiberglass insulation has an R-value that ranges from R-2.2 to R-4 per inch of thickness. Depending on the location and climate, an R-value of R-11 to R-25 is typically advised for basement insulation.
