The R Value of Foam Insulation Compared to Fiberglass

Property owners who want to insulate their homes or upgrade and improve the existing insulation that is already there have a number of options. There are a variety of different insulation materials available on the market, and each of them have their own individual properties and characteristics.

Spray foam is one of the most popular choices, in large part because it can help make a property much more energy efficient. That is appealing to property owners not only for the significant potential financial savings, but also because it is earth-friendly and promotes the conservation of natural resources.

A big factor in the success and popularity of spray foam insulation is its favorable standpoint when compared to alternative choices. In the insulation industry, R value is a very important characteristic. This is a way to measure and indicate how well the insulation can resist heat traveling through it.

When considering the level of spray foam insulation R value vs. fiberglass, spray foam is a clear winner. While both open-cell and closed-cell spray foam insulation offer attractive benefits for insulating a property, closed-cell foam insulation has a higher R value. In fact, it is among the leaders of all of the insulating options. Its R value can be up to double that of fiberglass insulation.

Even the impressive R value still doesn’t give the full story when it comes to the properties that make spray foam tough to beat. It can create a very strong and durable airtight seal, which serves as a nearly impenetrable barrier protecting the space from air and leaks or drafts.

Spray foam is excellent at preventing air leakage. Other types of insulating materials can often allow at least some volume of air to travel through the walls and the perimeter of the home. This represents wasted energy, and utility bills that are higher than necessary.

To achieve the maximum possible R value levels from spray foam insulation, it is important that the spray foam be applied by an experienced professional contractor with expertise in that specific area, one that is very skilled at all of the important steps involved in this application process.
