Keep Out Winter’s Cold
Attic insulation helps to keep a home warmer in the winter and cooler in the summer. Most homeowners don’t want to pay to have their HVAC system work overtime to heat and cool the great outdoors, making attic insulation necessary. Some types of insulation are better than others depending on the geographic area and climate, but insulation in general will result in a noticeable difference in any home's interior climate. Insulation works by trapping pockets of air to slow down the movement of heat escaping the house in the winter or entering in the summer. An “R-value” is assigned to all insulation to rate how well it slows the heat transfer. The higher the number, the better.
