When people think of insulation, their minds often move to how insulation improves warmth. For example, a coat with good insulation is a coat that helps its wearer stay warm. Likewise, the insulation in a home, such as in the attic and between the walls, helps the house stay warm during cold weather.
However, insulation works two ways: it’s also a method to keep a house cooler during the heat. Insulation is an important part of how a house stays energy efficient throughout the year. If your house has poor insulation or its insulation is aging and turning ineffective, you’ll end up with a house that’s more uncomfortable in winter and summer, along with energy bills that are far steeper as your HVAC system works overtime trying to combat the extra heat and cold.
