Insulating both the interior and exterior walls is important if you want to maximize your home’s energy efficiency and save the most money
Wall insulation is usually done when the home is about to be re-painted, re-stuccoed or texture-coated. The reason for this is due to the many holes we must drill on the face of the walls. Wall insulation can not be injected through the attic area nor from underneath the home. We have to drill holes on the face of the wall, from either the exterior or interior.
Insulating your walls in general offers countless benefits, and each type of insulation has its own advantages as well. Fiberglass and cellulose insulation are superior at stopping heat transfer, and both of these types of insulation also provide good sound control, reducing noises from both outside and between different rooms in your home. Spray foam insulation is great at filling small cracks and holes and around pipes, wiring, etc.
