How Do You Install Foam Board Insulation?
Foam board insulation can be bought in a few different types. The type you choose will depend on the R-value you require and where you install it. The least expensive of the boards is called MEPS. It has the lowest R-value and is a little difficult to work with because it warps and chips very easily. XEPS is a higher-density foam board and easier to work with. It has a higher R-value per inch and doesn’t absorb moisture as quickly. Many municipalities have regulations on how this insulation is to be installed, both for moisture and fire issues. Make sure you check with your local building code office before installation. Frame out a basement wall. Foam board insulation is flammable and must be covered with drywall or some other covering. So if you’re installing on a basement or other wall with no framing, you’ll have to frame the wall to install the outer covering. Use 2 by 3s for the plates and 2 by 2s for the studs. Make the studs 24 inches apart. Use three 8-foot 2-by-3 inch boards
