If you’re trying to decide between spray foam and fiberglass, here’s a breakdown of the key differences to help you make the best choice for your property: 

Fiberglass Insulation 

Fiberglass insulation, composed of fine strands of glass, has been a staple in the industry since the 1930s. It is affordable and widely available, but it has a lower R-value (the measure of insulation effectiveness) compared to spray foam. Fiberglass offers an R-value of 2 to 3 per inch of thickness, making it less efficient in extreme climates like Indiana’s. 

While fiberglass is easy to install, it can be messy and uncomfortable to work with, requiring protective gear to avoid irritation from the fibers. Over time, fiberglass can settle, lose its insulating properties, and allow air and moisture to penetrate. 

Spray Foam Insulation 

Spray foam insulation, available in both open-cell and closed-cell types, offers superior insulation performance. Closed-cell spray foam has a higher R-value (around 7 per inch) and is denser, making it ideal for areas that require maximum insulation. Open-cell spray foam, with an R-value of 3+, expands to fill even the tightest spaces, ensuring complete coverage. 

Unlike fiberglass, spray foam creates a seamless, airtight barrier that also acts as a moisture vapor barrier. This helps prevent issues like mold growth, water damage, and air leakage—problems that fiberglass cannot address effectively. 

Benefits of Choosing Spray Foam Insulation for Moisture Control 

One of the standout features of spray foam insulation is its ability to act as a moisture-resistant barrier. Unlike fiberglass, which can absorb moisture and promote mold growth, spray foam repels water, keeping the insulation dry and functional year-round. In humid climates like Indiana’s, this moisture resistance can help protect both the insulation itself and the overall structural integrity of your home or building.
