How Attic Insulation Affects Home Energy Use

Drafty rooms? High heating and cooling costs? If you notice any of these symptoms, it may be time to finally tackle that attic insulation project you’ve put off for quite some time. To learn why adding to or replacing your attic insulation can help lower your monthly heating and cooling bills, you first have to understand how insulation works.

How Attic Insulation Works

The Second Law of Thermodynamics states that heat always travels from warmer areas to cooler areas. When it comes to your home, heat will move from your living spaces to unheated attics, garages, basements and the outdoors during the winter months and flow into your home during warmer weather.

Attic insulation works to combat heat transfer by slowing conductive heat flow. To determine how well an insulating material will resist the flow of heat, you should consult the R-value, or the measure of thermal resistance. Depending on the type, thickness and density of the insulation, the R-value will vary. A higher R-value indicates better thermal performance.

Why Insulation Affects Home Energy Use

If heat is allowed to escape during the colder months and enter your home during the summer, your HVAC system will go into overdrive in an attempt to keep the interior temperature at your desired setting. When you lose efficiency, you lose money. It’s that simple.

Attic insulation helps prevent heat from entering or escaping your home, effectively reducing your utility bills throughout the year.
