If you want the best performance from your HVAC equipment, your home has to have adequate insulation. In addition to insulating the attic, you might need to add wall insulation too. There are a few ways to add wall insulation. Some methods require opening up the walls, and others don't. Here's a look at three ways to improve the insulation in your walls.
Blown Insulation Fills Wall Cavities
Blown-in insulation is easy to have installed since the insulation contractor doesn't have to open up your walls. Instead, the contractor drills a series of holes in the wall and blows the insulation into the wall cavity. You can choose cellulose, rock wool, and fiberglass loose-fill options, depending on your preferences.
Once the insulation is installed, the contractor fills the holes so they are barely noticeable. The insulation fills the entire cavity from bottom to top, so your home should have improved protection from the outside temperatures, and that can help your HVAC keep your home more comfortable all seasons of the year.
Fiberglass Batt Insulation Requires Opening Walls
An advantage of fiberglass batt insulation is that it is the most affordable option. The disadvantage is that your walls have to be opened up to install the blankets of fiberglass.
If you're remodeling and putting up new walls, that might not be a problem. However, you may not want to open up the walls just to put new insulation in, as that adds to the cost and disrupts your home.
Foam Insulation Can Be Sprayed Or Injected
Another option you have for wall insulation is foam. Spray foam can be used if you intend to open your walls. If you want the insulation applied without opening the walls and replacing drywall, then foam injection can be done. To inject the foam, the contractor drills holes in the wall cavities and uses a hose to fill the cavities with expanding foam.
The contractor can inject the foam through almost any kind of siding, even brick. In the case of vinyl or aluminum siding, a panel may be removed first so holes can be drilled in the side of the house. If you have brick siding, the holes can be drilled in the mortar and then filled back in. This makes the holes nearly invisible.
When foam insulation cures, it gets hard. This quality allows it to act as structural support for your home and to provide a sound barrier. You can even have foam insulation added to interior walls for soundproofing. A downside to spray foam is that it is a more expensive type of insulation.
