This, of course, helps to dissipate moisture and mold – two things that no one wants to see in a basement.

What type of insulation should I use for my basement walls?

between the 2x4s and the concrete. If you live in South Carolina, Alabama, Oklahoma, Southern California, or anywhere colder, your basement walls should be insulated. If your home lacks basement-wall insulation, it’s much easier to install interior insulation than exterior insulation.

Can you put foam insulation on the walls of a basement?

You can install foam insulation boards on the walls of a basement to keep it cool or to warm it up. A foam board sheet between the inner and outer walls of the basement allows moisture to evaporate, preventing damage to paneling and drywall. Foam board has various thickness and R values.

How to install insulation board in a basement?

Twist the 3-inch side to the wall and leave a space between the screws of at least 6-inches. Connect furring strips at the top of the wall with the same spacing as the screws. In a corner, fasten two furring strips. Connect them to the top and bottom strips.

Does foam board need a vapor barrier?

In houses with spray foam insulation, however, vapor barriers are not necessary. Quality closed cell foam insulation acts as a vapor barrier and does not absorb moisture; at the same time, the insulation prevents leakage by closing air gaps.

Where should I put the vapor barrier in my basement?

Vapor barriers should be located on the exterior of basement assemblies allowing inward drying to the basement space where moisture can be removed by ventilation or dehumidification.

What should I insulate my basement walls with?

frame your wall against the rigid foam with a thermal break of foam (1/4″?) between the bottom sill and the concrete floor. optional walls insulate with fiberglass batts against rigid foam. I’ve also read that nominal insulation for the basement walls should be between 15 and 20R.

Which is the best foam insulation for concrete?

Expanded polyurethane (EPU) serves as the best rigid foam insulation for creating insulated concrete forms (ICF). These ICFs replace traditional wooden forms, and act as a mold for freshly poured concrete. Instead of the standard foam sheets associated with rigid foam insulation, ICFs come in the form of hollow foam blocks.

How to install rigid foam insulation in basement?

Apply liberally – specifically in the corners and along edges of a piece. 2. Use something to hold the boards in place while the adhesive cures. I had all my framing lumber already in the basement so I just used that. You don’t need a tremendous amount of pressure – just something to keep the board in place and firmly up against the wall.
