Insulation is a great way to keep your home cooler in the summer and warmer in the winter without blowing your utility bills. There are many different types of insulation on the market, including fiberglass and cellulose. However, spray foam is a highly effective option that can drastically improve the energy efficiency of your home. Many homeowners wonder if it is possible to add spray foam to existing walls without having to tear down the wall or drywall. The answer is yes, and it’s actually a pretty simple process.
The key to successfully adding spray foam insulation to an existing structure is having access to the interior of the wall. This means drilling a small hole in an inconspicuous location, such as behind a light fixture or electrical outlet, and using the tool provided to carefully remove the existing insulation. It is important to note that this type of demolition can be messy, and drywall may need to be patched afterwards. In most cases, it is best to have a professional perform the work to ensure the job is done correctly and without damaging your home.
Once the wall is accessible, the can you add spray foam insulation to existing walls foam can be sprayed in place between studs and joists to fill any gaps and crevices. This will include the space around the windows and doors, which is often not properly insulated. It can also be used to insulate the attic and rim joists of an existing house or commercial building. Spray foam is an ideal solution for retrofitting walls, as it conforms to the unique layout of a structure and can be used in hard-to-reach spaces.
As the spray foam expands, it fills the nooks and crannies of your existing wall to create a sealed thermal envelope, saving you money on your heating and cooling bill year-round. In fact, Meritage estimates that a well-insulated home can save 20% on energy bills, compared to an uninsulated home.
The benefits of re-insulating your existing walls go beyond energy savings, however. It can dramatically increase comfort by helping reduce the noise from outside and between floors, while improving air quality by reducing the amount of pollutants like dust and pet dander entering your home. Additionally, the vapor barrier of spray foam will help keep moisture from getting past the exterior walls and causing mold or mildew problems.
Aside from the cost and hassle of removing drywall, another concern of DIY spray foam insulation is the risk of exposure to toxic chemicals. This is why it is so important to hire a professional who has the necessary training, experience, and equipment. This includes the use of safety goggles, masks, and protective suits when working with the chemicals.
