Installing insulation in your attic is perhaps the most efficient way to protect your home's energy efficiency and prevent moisture damage. But given the variety of insulation available on the market, you must be confused about which type of insulation is best for your attic.
What Factors Affect the Type of Insulation You Choose for Your Attic?
The answer depends on several factors, and perhaps the most significant ones are cost and R-value. Let's look at each of them.
R-value refers to the insulation material's ability to resist the transfer of energy. Some of the factors that can affect the R-value include the type of material, density, thickness, and where and how it is installed.
Another critical factor is the cost. The best type of attic insulation doesn't have to be the most expensive one. You can find relatively reasonably priced insulation that is energy efficient.
Spray Foam Insulation - The Best Attic Insulation
Considering the cost and R-value, spray foam insulation is the best attic insulation available on the market. While the R-value may vary, the value of open-cell spray foam insulation is around 3.5 per inch. Moreover, you can go for fire-rated spray foam insulation that offers extra protection. However, spray foam insulation is slightly more expensive compared to other insulation types.
Regardless of its cost disadvantage, given the energy efficiency it offers and moisture control it provides, spray foam insulation is worth it.
