One of the steps you'll probably have to take, when you renovate an older home, is to install new insulation. When you go to the trouble and expense of remodeling a home, making it energy efficient is probably high on your list of priorities. There are different choices when installing insulation, but spray foam is something you should seriously consider. Here's why it's a good choice for an older home.
Spray Foam Is Easy To Put Between Walls
If you're opening up the walls to replace wiring or drywall, then the ease of adding new insulation might not be as big a factor. If you don't want the expense of ripping open walls just to install new insulation, then spray foam could be the solution. It can be sprayed between the walls through a small opening that's drilled into the wall and then filled over. If you do plan to open the walls, then spray foam is still a good choice, since it goes on fast and spreads out to a hard barrier that keeps water and bugs from getting through.
Spray Foam Seals As It Covers
Old houses are often very sturdy, especially if they haven't had any structural damage. However, it's fairly common to find many openings to the outside, due to settling or animal damage. It's a tedious job to go over every inch of your attic to manually fill each slight opening to keep out bugs and drafts. However, sealing all the gaps to the outside is very easy when you use spray foam. Although you'll still want to fill obvious gaps, and maybe reinforce areas where pipes go through the roof with a can of spray foam, all the hidden gaps are filled in, as the spray foam expands. The foam folds itself around bends, and it flows into corners. This ensures your entire attic is sealed the way it should be in order to be energy efficient.
Many new homes have spray foam insulation applied when they are being built. It's also an excellent type of insulation for an older home that needs to be more energy efficient. This type of insulation is generally installed by a contractor, since the foam can be difficult to work with and it dries to a hard surface rather quickly. It's not the best choice for DIY installation, but it could be the best choice for keeping your home warm and free from drafts, which helps lower your power bill. Insulation contractors can help you determine if spray foam insulation is right for you.
