Insulation & Windows

Insulation in your attic. Higher R-value keeps more heat in during winter and reduces your energy bills.

Insulation in your exterior walls. Higher R-value means better protection from cold and heat.

Insulation in your basement walls. Reduces heat loss through below-ground walls into the earth.

Insulation under your basement floor. Reduces heat loss to the ground below your home.

Your window type. Triple-pane windows block more heat transfer than double-pane, keeping your home more comfortable. SHGC (Solar Heat Gain Coefficient) measures how much sun heat passes through the glass — a lower number means less heat from sunlight.

How well-sealed your home is. A lower ACH (air changes per hour) means fewer drafts and less energy wasted on heating air that leaks out. A tight home needs a ventilation system for fresh air.
