How to insulate walls from the inside
Insulating walls from the inside is an effective way to improve the energy efficiency of your home and save on heating and cooling costs. It involves adding insulation material to the inner side of the walls, creating a barrier to prevent heat transfer. This method is particularly useful when exterior insulation is not feasible, such as with solid masonry walls or in buildings with historic preservation restrictions.
In this article, we will discuss the different types of insulation materials that can be used to insulate walls from the inside, the installation process, and the benefits of this method. Whether you’re looking to improve the comfort of your home or reduce your energy bills, insulating your walls from the inside can be a worthwhile investment.
One of the most commonly used insulation materials for interior wall insulation is fiberglass batts. These batts are made from tiny glass fibers held together with binders. They come in rolls or pre-cut panels and are relatively easy to install yourself. The fiberglass batts can be inserted between the wall studs and secured with staples or glue. This type of insulation is highly effective and provides excellent thermal and acoustic performance.
In addition to fiberglass batts, there are other insulation materials that can be used for interior wall insulation, such as rigid foam boards, spray foam, and blown-in insulation. Rigid foam boards are excellent for insulating uneven walls and offer high resistance to moisture and mold growth. Spray foam insulation is ideal for hard-to-reach areas and provides an airtight seal. Blown-in insulation, on the other hand, is perfect for adding insulation to existing walls without major disruption.
