Spray Foam Versus Fiberglass Batting Insulation

insulating a homeOne of the biggest decisions today’s homeowners face is between spray foam insulation and fiberglass batting insulation.

There are pros and cons to each form of insulation. Learn the differences between spray foam insulation and fiberglass batting insulation today.

Gap Control

Many of the advantages of spray foam come from its superior gap control. After being sprayed onto a surface, spray foam expands over 100 times to fill in every nook and cranny within the space.

Fiberglass batting, on the other hand, leaves huge gaps between batts. If you look at a home using a thermal imaging camera, you can often see air leaking out between these batts. If you want thorough, gap-free coverage, then spray foam is your best option.

Energy Savings

It’s estimated that spray foam insulation saves homeowners about 30% to 50% in energy costs. Whether you’re heating your home in the winter or cooling it in the summer, it will be significantly more efficient after you install spray foam. Keep in mind that the 30% to 50% number is above and beyond what’s offered by fiberglass batting.

Noise Control

Some people install spray foam for the insulation benefits. Others install it exclusively for noise control. Since spray foam expands over 100 times on a surface, it provides complete, gap-free coverage. This makes it difficult for any type of energy to escape – whether that energy is sound energy or thermal energy.

Ultimately, the difference in noise control between spray foam and fiberglass batting is substantial.

Moisture Control

Getting mold in your home can be devastating. It can negatively impact the health of your family and sacrifice the structural integrity of your home.

Obviously, it’s in your best interests to avoid mold growth. Spray foam insulation does exactly that by providing superior moisture control. This reduces the risk of mold growth compared to fiberglass batting. Most homebuilders now recommend against the use of fiberglass batting in areas at risk for mold growth, including basements, crawlspaces, exterior walls, and attic floors.

The Industry’s Best R-Value

Ultimately, the benefits of spray foam boil down to a metric called R-value. R-value measures the thermal resistance of a particular material. Higher R-value means the material is better able to resist heat transfer, which means it’s less energy efficient when insulating your home.

When you compare the R-value of fiberglass patting with spray foam, it’s clear which one is the winner:

Fiberglass batting: 2.5 R-value

2 Pound Closed Cell Spray Foam: 7.0 R-value

Ultimately, that means you need to use less spray foam to offer the same insulation value as fiberglass batting. That means greater energy efficiency and utility savings.

Pricing

This is one category where fiberglass batting beats spray foam: if you’re looking for a cheap way to insulate your home, then you can’t go much cheaper than fiberglass batting.

It’s typically 2 to 3 times more expensive to insulate a home with spray foam than it is to insulate with fiberglass batting.

Ultimately, spray foam insulation is the winner in all but one category: price. And spray foam installation experts are quick to remind homeowners that they typically recoup the costs of spray foam insulation within 5 years: that’s how quickly you start saving money on utility bills.
