Fiberglass is one of the most inexpensive and common insulation choices available. It’s almost always used in new construction unless the home is a custom build for a specific customer.
While fiberglass doesn’t have the benefits of other insulation options like cellulose or spray foam, it can be a very economical solution to problems with retaining your heat and cold air.
Do you have fiberglass insulation in your home, and you’re considering upgrading? Here’s what you need to know to make the best decision for your situation!
Installing Batt Fiberglass Insulation
Fiberglass insulation is installed in sheets called “batts,” which are placed between studs behind the wall. They are inexpensive and simple to use, but they can easily be installed incorrectly.
In order to properly insulate your home, fiberglass has to have six points of contact with the cavity, sheathing, and drywall. They have to be cut to fit around electrical boxes, wires, and pipes.
Many DIYers install fiberglass incorrectly, by not filling the cavity fully or by compressing the batting. That’s why it’s vital to have a professional install this insulation if you plan to use it. If errors are made in installation, you won’t get the performance you need from this product.
R-Values of Fiberglass
Of all of the three insulation options – fiberglass, cellulose, and foam – fiberglass has the lowest R-value. There are different types of fiberglass that can help you achieve slightly better results, but you’re still not going to get the performance of cellulose or foam.
This is why many homeowners decide to retrofit their homes with cellulose or spray foam in order to improve their insulation. Most importantly, airflow is reduced with cellulose and blocked with foam, which can make a big difference in your heat and cold retention.
Upgrading the Insulation in Your Home
If your home is a recent build or has never been re-insulated, it’s likely that you have fiberglass insulation. The good news is that you can do a lot to improve your house’s energy retention!
Cellulose is a good mid-level upgrade. You’ll get much better R-Values and reduced airflow, without paying a bundle. But if you really want the best results, you want to look at spray foam. It’s got zero airflow and excellent R-Values.
Both cellulose and foam can easily be retrofit into your home without having to take all the walls down. Fiberglass can stay in walls while other insulation is added, although old cellulose would need to be vacuumed out.
In the attic, all old insulation will be removed. Be sure to have a professional remove fiberglass for you. Not only do you want to make sure you don’t tear it or miss any, you also need to wear special safety equipment when dealing with fiberglass insulation.
