How To Add Insulation To Your Walls And Floor
If the insulation in your attic is adequate, but your house still seems chilly, you should call an insulation contractor to check the rest of your home. It may not have insulation in the walls or under the floors. By insulating these areas and sealing cracks around windows and doors, you can stop chilly drafts and lower your power bills. Here's how you can add insulation to existing walls and floors.
Blown In Insulation
Blown in insulation is ideal for insulating your walls. This material is made from small bits of cellulose or fiberglass. The insulation is loaded into a blower and directed inside your walls with a hose. The loose bits are able to conform around wires and pipes between the walls. To get the hose inside your wall, the contractor has to make openings along the top of the wall. There will be a small hole between each of the studs. The contractor inserts the hose into the hole and fills the cavity with insulation, then pulls out the hose and proceeds to the next hole. When the job is done by a professional, the holes are sealed and invisible when finished.
Other options, such as batt and spray foam work too, but in order to apply them, you need to remove the drywall so you have access to the walls. Therefore, they are only good options when you're renovating and replacing drywall anyway.
Batt And Foam
If you want to apply insulation under your floor, you can use fiberglass batt. All you have to do is push the batt between the floor joists and staple them in place. These are a good option if the floor is above basement space. However, if you have a crawl space that is outside, you may prefer to use spray foam insulation instead. You can use spray foam in your basement too, but it is ideal for outside use because it repels moisture and will stand up to insects and rodents much better than batt.
While the contractor will use a canister to apply spray foam over a large area like the underside of your floor, you can use a small can of spray foam to close gaps around pipes and vents that exit your home. In addition to spray foam, you can use caulk, plastic, and even fabric draft guards to keep cold air out of your home. The tighter your home, the warmer you'll be in the winter, and the more efficiently your HVAC will operate.
