Air sealing is the process of sealing leaks in a home’s building envelope to limit the amount of air that leaks out of and into the house. Conditioned (heated or cooled) interior air leaking out of the house is called exfiltration. Outside air that leaks in is called infiltration.
Heat passes all too easily through a poorly insulated attic. In the winter, heated interior air rises naturally by convection and escapes into the attic through numerous air leaks.
For many years, the standard insulating strategy for basements and crawl spaces was to install fiberglass batts between the ceiling joists in the basement or crawl space.
Ceiling insulation is an important component in any home’s weatherization plan.
Crawl Space Insulation
It’s unfortunate but true. Builders often omit crawl space insulation or install the wrong type of insulation.
If your uninsulated ductwork is located in an attic, basement or crawl space, the duct temperature will be the same as the temperature of these spaces.
Ice damming can cause problems like water leaking into the attic, which could soak the wood, insulation, flooring, or upstairs ceiling, and even possibly the valuables stored in the attic. It can also ruin rain gutters.
Spray Foam Insulation
Spray foam insulation is more expensive than other types of insulation, but the extra cost is usually justified given the advantages it offers.
Injection Foam Insulation
No single type of insulation is the best for every application. Energy experts from all over the world tell us that each type -- cellulose, fiberglass, spray foam, rigid board, or even recycled denim (!) -- has its plusses and minuses. But now there’s a product that gets closer to being the one insulation that does it all.
The air temperature in the room is comfortable, but the floors are cold. When your floor isn’t properly insulated, even a “warm” room can feel chilly because your feet are cold.
On hot summer days, extra protection in the roof or attic can prevent super-hot roof temperatures from reaching your living space.
