How Much Insulation is Enough?

How Much Insulation is Enough?

Nearly 90% of homes in the United States are under-insulated and most homeowners don’t even know it. Insulation is incredibly important when it comes to improving the efficiency of your home and controlling the temperature. Insulation is most prominent and most important in your attic since heat rises and therefore this is where most a lot of heat escapes from your home. But insulation can be used everywhere in your home including in the roof, floors, walls, windows, and doors.

Walls

About 30% of your home’s heating and cooling energy is lost through your walls so it’s important to insulate them to help trap heat in your home and to keep heat from entering your home.

There are two types of wall insulation: cavity insulation and solid wall insulation.

Cavity Insulation

Most building walls are made with cavities or gaps in them where building material is not necessary for structural integrity. Cavity insulation (made of fiberglass wool or rock wool) is added into these gaps to prevent an excess amount of heat from exiting your home through the walls.

Solid Wall Insulation

Some walls have no “cavities” or gaps where they can be filled with insulation, but this doesn’t mean that you can’t insulate them. To insulate these walls, you’ll do it either on the interior or exterior of the wall, rather than inside the wall. This method of insulation is typically more expensive, but the energy savings make up for it.

Windows and Doors

As we’ve talked about in previous blog posts, double or triple paned windows are the best route to go for improving your window efficiency, but you can also go the less expensive route and add a low-E coating to your windows to reduce heat loss.

The areas around your windows and doors are also a really easy way to lose hot and cold air from your home. To prevent this loss of air, add caulking to the gaps around the window and door casings. This caulking will periodically need to be replaced or reapplied but it is an easy and effective way to make your windows and doors more efficient.
