Recommended Insulation Levels
The recommended insulation levels for Canadian homes have been rising through the years, reflecting increased heating costs and concern for energy conservation. The precise level of insulation which can be justified on economic grounds (cost of insulation vs. fuel saving) varies with climate, fuel costs, insulation prices and other factors. It is possible, however, to recommend one set of minimum insulation levels which are generally applicable across the country.The recommended levels for existing and new housing will differ because current construction practices often limit the amount of insulation that can be added. However, innovative construction techniques will allow higher levels for new housing in the future.
New Housing
The building codes for new homes are presently being re-evaluated and updated to meet today's energy circumstances. New construction techniques, such as 6-inch wall studs and exterior insulation, are being considered to make new houses suitable for the energy pinch ahead. Even solar heating systems are being developed and tested.
When you buy or build a new house, be sure it has the maximum amount of insulation possible. You might want to look into 6-inch wall studs to permit more insulation in the walls, and consider built-in basement insulation. Your new home should at least meet the insulation levels recommended above. The money you invest in extra insulation now will more than repay itself in the years ahead.
