Spray Foam Insulation vs. Fiberglass: A Guide to Home Insulation

Spray Foam Insulation vs. Fiberglass | MY Insulation LLC

When it comes to home insulation, you have a lot of choices—and that can be a bit

overwhelming. Which type of insulation is the best for your home, your climate, and your budget? We’ve already talked about cellulose insulation, so now let’s focus on two popular options used by insulation installers near me: spray foam and fiberglass. Michigan and Indiana insulation must do battle against a whole gambit of foes, from heat and humidity to below-freezing weather. Spray foam insulation vs. fiberglass insulation can be a tough decision to make due to such extreme weather changes! In this blog, we will break down some of the main differences between spray foam insulation vs. fiberglass.


Fiberglass Insulation  

Created from tiny strands of plastic coated with strands of glass fiber, fiberglass has been used as insulation since the 1930s in the United States. Today, it is one of the most common ceiling and floor insulation materials worldwide, with an R-value of about 2 to 3 per inch of thickness. R-values, calculated by comparing the temperature difference between two sides of an insulator, are used to rate an insulating material’s resistance to heat conductivity. 


Though comparatively fiberglass insulation has a low R-value, it also boasts a budget-friendly price tag. This is probably what has kept fiberglass insulation popular for so long now, as well as the ease of access. Almost any construction company is able to source and install fiberglass insulation—the process is simple enough that handy homeowners have been known to do the installation themselves.  


Spray Foam Insulation 

There are two main types of spray foam insulation used in residential, commercial and industrial properties: open-cell and closed-cell. Closed-cell spray foam is denser and, therefore, has the highest R-value (about 7), while open-cell spray foam (R-3+) is designed to expand exponentially and fill in those tough-to-reach corners and crevices. Using both injection foam and spray foam, as we do here at M.Y. Insulation, we provide full coverage with as high a rating as possible.  


The beauty of spray foam is that it allows us to capitalize on the high R-vale of foam without the hassle. Instead of maneuvering dozens of foam sheets into a space, liquid-stored foam allows easy handling and smooth, even coverage of insulation. Fort Wayne, Indiana, as well as Michigan and the surrounding regions, can benefit greatly from the use of spray insulation.  


Insulation Foam & Humidity Issues 

The polyurethane foam we use keeps buildings warmer in the winter and cooler in the summer and provides a moisture-resistant barrier. Compared with fiberglass, the cost of installing foam insulation will cover itself in the coming year's thanks to all the saved energy bills—especially in an environment like ours. Foam works all year long to block water particles from entering your home, breaking down insulation and other building materials.
