As the temperatures rise and summer approaches, homeowners in Chicagoland are gearing up to combat the heat. While most focus on cooling their homes efficiently, many overlook a critical aspect of home comfort: attic insulation. 

Attic insulation plays a pivotal role in maintaining a comfortable indoor environment year-round, especially during the scorching summer months. ARC Insulation offers high-performance attic insulation services throughout Naperville and surrounding areas. With our help, your home will be cool and comfortable this summer—and for many more to come.  


How Attic Insulation Improves Summer Comfort

Attic insulation acts as a barrier between the hot outdoor air and the cooler air inside your home. Here’s how it works to keep your home comfortable during summer:

  • Prevents Heat Transfer – During summer, when the sun beats down on your roof, the attic can become a heat trap. Without proper insulation and ventilation, this heat seeps into your living spaces, making your cooling system work harder to maintain a comfortable temperature.
  • Reduces Air Leakage – Properly installed insulation, especially when combined with air sealing, prevents warm air from infiltrating your home and cool air from escaping. The stack effect, which is when hot air rises and escapes through gaps in the attic, is also mitigated by insulation.
  • Maintains Consistent Temperatures – Attic insulation’s thermal barrier eliminates hot spots and ensures comfort throughout your entire home. This is particularly important during summer when temperature differentials between the attic and living spaces can be significant.

Common Problems Attic Insulation Can Solve

Attic insulation addresses several issues that can plague homes during the summer months, including:

  • High Cooling Bills – Inadequate insulation leads to excessive energy consumption as your cooling system works harder and more often to combat heat gain.
  • Uneven Cooling – Insufficient insulation can result in temperature variations within your home—especially the second level, leading to hot rooms upstairs. 
  • Moisture Problems – Proper insulation helps regulate moisture levels, preventing condensation buildup that can lead to mold growth and structural damage.
  • Poor Indoor Air Quality – Effective insulation and air sealing keeps outdoor pollutants and allergens at bay, promoting healthier indoor air quality.
  • Stuffy Rooms – Without attic insulation the rooms on the second level of your home or above the garage will have issues staying cool during the summer. 

    Why Insulation & Air Sealing Go Hand in Hand

    While insulation provides a barrier against heat transfer, air sealing complements its effectiveness by sealing off any gaps and cracks that allow conditioned air to escape and outdoor air to infiltrate. Together, insulation and air sealing create a secure thermal envelope that maximizes energy efficiency and indoor comfort.


    The Best Types of Insulation for Attics

    At ARC Insulation we use cellulose and spray foam insulation for attics, both of which offer superior protection against the outside elements.

    • Cellulose Insulation Made from recycled paper products, cellulose insulation provides excellent thermal resistance and is treated to be mold, pest, and fire resistant.
    • Spray Foam Insulation Known for its superior insulative and air sealing properties, spray foam is an all-in-one product for maximizing energy efficiency.
    • Duct Sealing with Aeroseal technologyWhether your ducts are located in your attic or elsewhere in your home, duct sealing will help balance airflow, prevent air leaks, and reduce the chances of condensation or mold.
