Attics and Basements – Where to Insulate and Why

Most homeowners think of upgrading their home’s insulation during fall and winter. This is when homeowners hear their furnaces run, begin to feel the pinch of high energy bills and notice cold areas around their homes. If you’re ready to upgrade your home’s insulation, here are two areas to address:


When air escapes a home it goes up, not out. This makes your home’s attic the first place to start when making home energy upgrades. Upgrading your attic insulation adds a thermal layer that will help maintain your home’s inside temperature. You can go one step further by sealing air leaks in your attic. According to ENERGY STAR, 60% of a home’s air leaks exist in the attic. Insulating and air sealing your attic will help make your home more comfortable and save money on energy bills year after year.

Basement Box Sills

Box sills are the area of the basement where the outside wall of the home meets the joist of the first floor. Box sills are constructed with a thin layer of siding, plywood and foam board. These materials are not enough to prevent energy loss, cold basements and high energy bills. In fact, some estimates indicate that 25% of a home’s heat loss is a result of uninsulated box sills. We recommend adding spray foam insulation to box sills to both insulate and air seal this critical area.

A friendly reminder: Schedules fill up quickly during fall and winter. Be patient when scheduling with a qualified insulation contractor. It’s worth waiting for an insulation expert to review your home and recommend proper energy upgrades.
