If you're planning to finish your basement, you'll want to add insulation to the walls to help control condensation and temperatures. Even though it's a more expensive choice, spray foam insulation might be best for a basement renovation. Here's why.
Some Insulation Has A High Risk Of Mold
Your basement is vulnerable to moisture from water vapor, cracks in the concrete, and condensation. Options that are commonly used in upper levels of your home may not be suitable for a basement.
Fiberglass batt and cellulose blown insulation wick up moisture and they can eventually mold. Since insulation is hidden, you might not realize your basement has a mold problem until the framing studs rot out or until your basement has a foul odor.
Spray Foam Blocks Water Vapor
Spray foam is applied between wall studs. The contractor sprays it out of a tank while wearing protective equipment. The liquid spreads as it turns into foam and expands. Then the foam dries and becomes hard so it stays in place and becomes part of the wall. This allows the foam to form a continuous layer of protection for your basement walls that blocks water vapor.
The foam can also flow in areas such as cracks, gaps around windows, and pipe openings so that water and air leaks are completely blocked. Spray foam can help your basement stay dry, which is important if you plan to put furniture and other valuables in the space after your renovation.
Spray Foam Has A High R-Value
R-value is a measure of how well insulation blocks heat transfer. Spray foam comes in two types: open cell and closed cell. Your contractor will probably use closed-cell foam for your basement because it's the type that blocks water vapor and stands up against moisture and mold.
Closed-cell foam also has a higher R-value than open-cell foam and some other types of insulation. This means it will be easier to keep the temperature in your basement at comfortable levels during all seasons.
Installing spray foam isn't usually a DIY operation. Instead, hire a contractor that provides spray foam services so the right type of foam is chosen and applied correctly. Once the foam is dry, it's hard and very difficult to remove, so you want to make sure the installation is done correctly.
Also, before you have the insulation added, waterproof your basement if necessary to reduce the risk of basement flooding. Once your basement is dry and insulated, it's ready to transform into extra living space for your family.
