Insulating Walls Without Removing Drywall: A Comprehensive Guide

Injecting foam insulation is the ideal solution for insulating walls without removing the drywall. There are several types of injectable foam available, including RetroFoam, which can be used without having to take down the drywall. To add insulation to walls without removing it, you can drill holes in the cladding and blow spray foam or cellulose onto the walls from the outside. Cut a 1- to 2-inch hole between the uprights at the top of the wall and then spray the insulation into the hole with a hose.

Replace the cutouts, fill them with wood putty, and then gently sand and paint to restore the coating. Alternatively, you can use aerosol foam insulation, which is injected into cavities in the wall. To know when it's full, feel for backpressure in the hole. Older homes often lack insulation, but almost every home can benefit from additional insulation.

Spray foam insulation is especially effective as it can make its way into every nook and cranny. Insulating a loft under the roof is a great starting point when you want to insulate your house without touching the drywall.
