Our team specializes in basement sill box insulation to prevent cold air infiltration and help you expand your living space. Because they are located below ground, basements are naturally cold and damp. Poorly insulated basement box sills add to the problem, making space feel even colder. A cold basement can affect the temperature of your home’s first floor. It can also put a strain on any mechanical components in your basement, such as your HVAC system. Insulating your basement box sills can make your basement more comfortable for your family.

Box sills are located around the edge of the basement ceiling where joists meet the wall of the basement. This is one of the thinnest points in a home’s exterior. With little protection from the outside air temperatures, box sills can dramatically affect the temperature in a basement.

Many installers place fiberglass batt insulation in a box sill to insulate the area, a technique that meets local building codes. Although this insulates box sills, it does not seal the many air leaks that are found around box sills. We recommend using spray foam insulation as the best way to insulate box sills to insulate and air seal this area. Spray foam insulation adds thermal protection and seals air leaks in one step.
