How Attic Insulation Can Reduce Your Energy Consumption

Published January 13th, 2023 by Energy Plus Home Improvements

Is your utility bill too high? U.S. households average over $2,000 per year in energy costs. These costs also spike with inflation.

HVAC systems are typically the energy pie's most significant slice. Around 50-60% of energy usage is heating and cooling costs.

Attic insulation is one of the easiest ways to reduce your heating and cooling bills. Even a top-notch HVAC system can't beat the sun or the wind chill. Read on to learn how investing in attic insulation saves you money.

Reduces Energy Loss

We learn that hot air rises in grade school. This trivia tidbit is also responsible for the earth's weather and climate system. Without this basic physics rule, life as we know it wouldn't exist.

The same principle applies to your home's mini-climate. Your HVAC system heats your home by creating hot air. The warmer air rises, and colder air comes in to replace it.

This is why a poorly insulated attic can lose nearly 60% of your home's heat during the winter. Home insulation works like a greenhouse effect. The stronger barrier prevents heat from escaping, making less work for your central air system.

This cycle also applies to cooling your home. As warm rises, cool air rushes to fill it. This means cooler air will take any opportunity to escape outside in the summer, including through your attic.

Blocks Incoming Heat

On the flip side, attic insulation also blocks unwanted heat from seeping in. Your roof bears the brunt of the sun's rays. An average roof absorbs up to 80% of incoming solar radiation.

Have you ever been inside an uninsulated attic on a hot day? It's toasty, especially if the humidity is high too. Some attics can reach a whopping 150°F (65°C).

Although warm air rises, temps this high will still transfer heat to the cold air underneath it. Your air conditioning must spend extra energy usage to maintain your thermostat setting.

The high heat also lowers the lifespan of your existing insulation and roofing system. You'll be stuck in an ever-increasing heat loop until you add proper attic insulation.

Manages Humidity

High humidity can also damage your attic and roofing systems. You aren't safe even in a drier, more temperate climate. Hotter air naturally carries and creates more humidity.

Condensation is also formed when hot, moist air comes into contact with cooler and drier surfaces. This includes the lower attic bits cooled by your home's HVAC system.

All these factors create a perfect storm of moisture build-up in your attic. If left untreated for too long, mold and rot can start to form.

Attic insulation keeps the temps cooler and more constant. This helps bring the moisture down to more manageable levels. It also extends the lifespan of your roof and home insulation.
