FAQs

Where Should I Air Seal?

By any measure, reducing air leakage (in and out of the home) is a cost-effective way to cut costs for heating and cooling. Draft proofing and weather-stripping are probably the most simple and effective methods for air sealing. But whatever the method, simple or more sophisticated, the return-on-investment makes every effort worthwhile. The fact is, air sealing is fundamental to energy efficiency, and the key to saving on heating and air conditioning costs through the year.

The idea with air sealing is to stop outside air from entering the home, while stopping indoor air from leaving the home. It’s a formula for enhanced energy efficiency where the homeowner can realistically experience reduced utility bills. At Great Northern Insulation, in-house experts help residential homeowners to identify sources of air leakage, assess viable options for air sealing, and provide retrofitting solutions that will result in significant annual savings every season.great northern insulation air seal

Ideally, a professional home energy audit will identify areas of wasted energy and specify options for resolution. It’s a step-by step approach that allows for focused corrective measures. Here, the GNI team can determine a course of action and recommend options that will deliver the best results. What’s important to remember is that air sealing doesn’t eliminate the need for good insulation that’s properly installed. Indeed, everything from insulation to ventilation matters.

In a good many situations, air sealing may require more than just routine draft proofing. And for the professionals at Great Northern Insulation, providing the right “fix” means improving energy efficiency in the home, while creating cost savings on heating and air-conditioning utilities. Just by example, a properly sealed, well insulated, and fully ventilated attic can do wonders for energy efficiency – and all with significant reductions on energy consumption and savings to match.

For Great Northern Insulation, it’s all about effectively sealing, insulating and ventilating.
