The U.S Department of energy states that if the walls on your home are properly insulated that your heating and cooling bills will be less expensive, along with having a more comfortable home. Before installing wall insulation, the walls should be sealed as well as being protected from moisture.
Wall insulation can be hard to install if you have a finished home. Unlike your basement and attic, the walls in your home aren’t *open* to putting insulation in after it is finished, since wall insulation is installed between the studs behind the drywall of the walls. Once the drywall are up, it is harder to install insulation, but you still have some options.
- One thing that you can do instead of insulation is to seal the walls and weather-strip any *doors that lead outside.* This is less expensive than insulating your walls, and with all *cracks* leading to the outside sealed, air won’t escape into or out of your house as much.
- Another option is to drill holes into the wall and blow insulation into it. The holes are drilled from the outside of the wall and are camouflaged well after they are sealed.
- If you are planning on remodeling the outside of your home, consider having insulation added while the siding is off. It makes it easy to install on the wall when the wall is exposed.
