As we all in pretty much a deep freeze, it’s important to insulate your home for warmth, comfort and saving on energy bills. A while back I wrote a story on PlanetGreen.com about the need to insulate where most people forget: the garage next to your home.
Homes with attached garages lead to energy waste.
The effort that goes into insulating the outside of the house is not often extended to the garage.
That’s a mistake and here is why:
If you insulate the floor above your unheated garage, it will help reduce the energy costs for the other insulated parts of the home. (Source: How Stuff Works.)
More about this:
Several different materials can be used for sidewall insulation: cellulose fiber, fiberglass, and a number of different types of foam. Each will not only retard heat flow from the inside of the house to the outside but will also cut down on air infiltration through gaps in the sheathing and other areas. Some foam products can be injected into sidewall cavities even if there is already insulation in place.
While sidewall insulation can be installed from inside the house through holes drilled into plaster or drywall, the usual protocol is to do it from the outside. This tricky job is best left to the experts.
Injection holes can be drilled through wooden clapboard siding and then plugged with paintable plastic caps, or some lengths of the siding can be removed and then replaced after holes have been drilled through the sheathing. Holes in stucco-sided homes can be patched with stucco-cement materials, and vinyl and aluminum siding can be temporarily removed and then replaced after the insulation-installation process is complete.
