How Basement and Crawl Space Insulation Saves You Money

Whether your property has a basement or a crawl space, poor insulation can lead to higher energy bills. This is because your heating and cooling system has to work overtime to cover for gaps in the performance of your home. Poor insulation and unsealed areas underneath your home allow conditioned air to escape your home and cold or warm air to leak in from the outside.

Increasing insulation in your basement or crawl space has two main effects. First our solutions are designed to seal air leaks and prevent the conditioned air from escaping your home. This ensures that any air in your basement or crawl space stays at the temperature you want it at. The second effect is reducing the amount of time that your heating and cooling system needs to be running. With increased R-Value your home will maintain the temperature you want for longer periods of time, causing your heating and cooling system to turn on less frequently.

Overall keeping your basement and crawl space properly insulated will save you money by using less energy to heat or cool your home. It also has the added benefit of keeping your home more comfortable during both the cooler and hotter months.

Why You Should Avoid Fiberglass Insulation for Basements and Crawl Spaces

Our insulation products are specifically designed for use in basements and crawl spaces in the Chicago area. While fiberglass insulation has been a popular choice for decades, there are two main reasons why it may not be the best choice for your basement for crawl space. 

Moisture and Mold: Basements and crawl spaces are prone to high humidity levels and moisture problems. Traditional fiberglass insulation absorbs moisture and can become a growth area for mold and mildew underneath your home. 

Energy Efficiency: Because fiberglass insulation is typically installed between the floor joists, whole areas of your basement or crawl space utilities are left uninsulated. This leads to your systems having to work harder to overcome the temperature difference between your ducting and the inside of your house. 

While fiberglass insulation has advantages in some use cases, it is not ideal for basements and crawl spaces. Our products are specifically designed with moisture resistance and energy efficiency in mind.
