Best Foam Board Insulation For Basement Walls

Insulating basement walls is important for several reasons. It can help to:

Reduce heat loss and save energy
Keep the basement warmer in the winter
Prevent moisture problems
Reduce noise
Improve the overall comfort of your home

There are several different types of insulation that can be used in basement walls, but foam board is one of the most popular options. Foam board is made from rigid polystyrene foam, which is a lightweight and durable material. It is also moisture-resistant and easy to install.

When choosing foam board insulation for basement walls, there are a few factors to consider:

R-value: The R-value of insulation measures its ability to resist heat flow. The higher the R-value, the better the insulation. For basement walls, an R-value of at least 10 is recommended.
Thickness: The thickness of the insulation will also affect its R-value. The thicker the insulation, the higher the R-value. However, thicker insulation can also be more difficult to install.
Density: The density of the insulation is another important factor to consider. Density is measured in pounds per cubic foot (pcf). The higher the density, the more durable the insulation will be. However, higher density insulation can also be more expensive.
Price: The price of foam board insulation can vary depending on the R-value, thickness, and density. It is important to compare the prices of different products before making a purchase.

Once you have considered all of these factors, you can choose the best foam board insulation for your basement walls. Here are a few of the best products on the market:

Owens Corning Foamular 150: This product has an R-value of 15 and a density of 1.5 pcf. It is easy to install and is available in a variety of thicknesses.
