Can Foam Insulation Be Installed in Existing Walls?

We still have a few weeks of winter left—the cold weather seems to drag on here in the Chicagoland area, doesn’t it? If you’re trying to keep your energy bills in check while keeping your home comfortable but it feels drafty and chillier than it should, you may need more insulation.

Do you need to re-insulate your home? Wondering if foam can be installed in your walls? Keep reading to learn more about foam insulation for existing walls!

Insulating Walls with Foam

So, can foam insulation be installed in existing walls? Yes, it can, depending on the type of foam. Rigid foam, or foam board, is typically installed during new construction projects, in unfinished walls. However, spray foam and foam-in-place insulation can be installed in enclosed, existing walls. It is applied using small spray containers or in larger quantities as a pressure sprayed (foamed-in-place) product and will expand and harden.
