How Attic Insulation Saves Money

Attic insulation keeps your home warm in winter and cool in the summer. As heat rises in your home it naturally moves to cooler areas and places where temperature differences are measurable. By insulating your attic spaces you provide resistance to heat flow ensuring that heated or cooled air remains in the interior and isn't escaping through your ceiling and roof. Inadequate insulation, gaps and leaks in your home wil cause your heating and cooling system to run longer and more often in order to maintain temperature in your home. As a result, your furnace or air conditioner will consume more energy which results in higher energy bills. Proper Attic insulation saves you money year after year; over time helping to pay for itself in lower heating and cooling costs.

Attic Insulation Basics

As part of our service we will measure the amount and depth of insulation currently in your home as well as the square footage of the attic area. Four Seasons takes a full service approach to your attic insulation needs. This means that we look at the ventilation, both the intake and exhaust, as well as the any insulation inadequacies that may be present. Four Seasons takes great pride in providing its customers the very best in quality installations and in customer service. We are committed to your 100% total satisfaction.

A quick way to see if you need more insulation is to look across your uncovered attic floor. If your insulation is level with or below the attic floor joists, you probably need to add more insulation. In the coldest climates, insulating up to R-60 is recommended. R-Value is the value given to insulation products that states their resistance to heat flow, with increasing values providing more insulation. An R factor of R-60 means you should have approximately 21” of insulation in your attic. Older homes tend to have less insulation than modern homes and overtime insulation settles causing the density to decrease. Over time, additional attic insulation can pay for itself by cutting energy bills by 20 - 30% or up to 10% annually on total annual energy bills.

Benefits to Proper Insulation

As more and more families look to save money by lowering their energy bills and home heating and cooling cost, they are discovering the benefits of improving and increasing the amount of attic insulation. When insulation is properly installed temperature differences from room to room are minimized. Insufficient insulation can lead to heat loss or heat gain. Heat loss occurs when the warm air inside your home escapes through, gaps and leaks in your walls, windows or attic to the exterior. Heat gains is the reverse phenomenon, when heat from the exterior enters your home reducing or replacing the cool air and causing your air conditioning system to work harder to compensate for the temperature differences.

By keeping a consistent temperature throughout your home you'll enjoy being warmer in the winter and cooler in the summer. As a result of proper insulation your heating and cooling system will run more efficiently reducing energy consumption and lowering your home energy bills. Furthermore, proper insulation reduces the chance that condensation will form which can result in the breakdown of building materials. Proper installation of attic insulation will ensure that you have even coverage without gaps or voids which can lower the R-Value of the insulation. Save time and save money by having your attic insualtion professionally installed by Four Seasons Home Services.


The Chicago area and much of Illinois is designated as Zone 5 by the Department of Energy in their R-Value Recommendations map. See the chart below for an explanation of R-Value ratings for Uninsulated and Insulated Attic spaces. The ratings determine the amount of insulation needed for each application.

What Does Zone 5 Mean To You? According to the United States Department of Energy, homeowners in Illinois and Indiana should have an R-Factor of R-38 to R-60. That means your attic should have a minimum of 14" of insulation present.

How To Tell If You Need More Attic Insulation? A typical home in Ilinois will need attic insulation with an R-Value between R-38 to R-60. R-38 is 14" of attic insulation and R-60 is 21" of total insulation. If you have less that 14 total inches of attic insulation you do not have enough. Consider having Four Seasons Home Services professionally instal your attic insulation.
