We’re finally starting to see some cooler weather here in Savannah, and soon we’ll be focused on keeping the warm air in and the cold air out. In order to efficiently maintain the temperature of your home, you will need to make sure it is properly insulated. Most new homes are constructed with energy efficiency in mind, however, older homes may not be insulated as well. There are a number of factors to consider when adding insulation to your home.
Perform an energy assessment
Whether you do the assessment yourself or have a qualified energy auditor perform the inspection, and insulation check will help you determine what type you have and where you may need to add or replace it. Good places to check include the attic, walls, and floor especially if it’s near an unheated space like your garage.
Determine your R-value
The R-value represents the resistance to heat flow of a particular variety of insulation. The R-value you need will depend largely on the climate you live in and what part of your home you will be installing new insulation. For example, in Savannah, if you want to insulate your uninsulated attic, you will want to choose insulation with an R-value of 3-6.
Where to Insulate
Once you figure out what you already have and the R-value you wish to achieve, you need to know where you need to insulate. In an unfinished attic, make sure you have insulation over the floor joists. Consider insulating the rafters if air is distributed into your attic space. Insulate your floor over cold spaces, such as vented crawl spaces and unheated garages. If you are replacing your exterior siding, consider replacing the insulation on your exterior walls at the same time. Injectable spray foam insulation may be used if you will not be opening up any walls.
In our climate, we have to deal with high humidity through at least half of the year. Controlling the moisture in your home will improve the effectiveness of your insulation improvements. Make sure your bathrooms and kitchen are properly ventilated and consider insulated your crawl space with a plastic vapor barrier.
