FAQs

How Do I Insulate My Walls?

Unlike today, insulation wasn’t a priority in older residential homes. Building science wasn’t well developed, insulation products were not sophisticated, and energy costs were much lower. If the home was cool in winter, pumping up the heat was no problem. And keeping the air conditioning on all summer was just as okay. There was little thought given to upgrading the insulation.

Today, a well insulated home is critical to creating energy efficiency and managing energy usage. And while most of the focus goes to obvious parts of the house like the attic and basement, other parts of the “building envelope” are neglected – like the walls (especially exterior walls). Truth is, even homes that aren’t so old have exterior walls that are very poorly insulated, if at all.

At Great Northern Insulation, installers have had considerable success with wall insulation using the unique “drill-and-fill” approach. It’s an innovative and highly effective installation for existing walls (both interior or exterior). And since the walls exist, this is a retrofit approach that does the job well - preventing undesirable air movement; stopping air leakage; and insulating all at once.

The “drill-and-fill” approach is the ultimate retrofit. GNI installers strategically drill small holes into a wall, with a focus on the cavities that are located between wall studs. Immediately after, a high quality insulation product (loose fill cellulose) is blown into each of the wall cavities where the holes have been drilled. When the insulation is at maximum, the holes are suitably patched.

For homeowners who find their exterior walls quite cold to the touch, the “drill and fill” retrofit from Great Northern Insulation is the ideal solution. Heating and cooling costs will be noticeably reduced, and the home’s HVAC system (heating and air conditioning) will operate with greater efficiently. Best of all, indoor comfort will be dramatically enhanced throughout the seasons.
