Access to places such as your attic or your basement is usually easy after the home is built. Upgrading in those areas are easy compared to your walls which are between drywall and exterior siding. At the Home Insulators three suggestions for our Free Estimates to upgrade insulation and energy are as follows.
Air Sealing the walls and weather-stripping exterior door.
Begin by air-sealing walls and make sure the exterior doors are weather stripped. Both of these are less expensive than insulating the walls but can still make a big impact on your homes efficiency costs.
- Blown-in insulation into the wall cavities. It is possible to drill a small hole at the top of the wall and blow insulation into the cavities. The holes are usually drilled from the exterior and are finished as clean as possible.
- Insulting walls when the siding on the exterior is replaced. If your house has siding and needs to be replaced, insulation can occur as this siding is removed.
U.S. Department of Energy on Walls
The United states Department of Energy says on their web sites that having exterior walls in your house that are properly insulated will not only increase the comfort of your home but will save money on heating and cooling costs. To get energy savings, you can add insulation to your walls. But before insulating your walls you should ensure that they are air-sealed the right way. In addition moisture should be considered a factor.
The Home Insulator will check the insulation levels in your wall cavities as part of a free estimate.
