No matter where you live in Colorado, adequate home insulation is key to reaping significant energy savings and reducing your overall carbon footprint. While fiberglass insulation has been the construction standard for decades, cellulose is a newer insulating product that’s giving fiberglass a run for its money in terms of cost efficiency, ease of installation and protection from air leakage.
Fiberglass versus cellulose
Cost – When it comes to cost, these two products are both inexpensive in terms of price per square foot. What can vary is the price of installation if you’re using a professional contractor. Take the time to compare your licensed contractors in terms of experience, reputation and total project cost in order to get the best installation for your money. Make sure to use an R-value that’s suited to your specific geographic location, and keep in mind that Colorado has four different zones.
Ease of installation – One of the reasons fiberglass is so popular is because its blankets and batts are easy to install. This isn’t to say that experienced installation isn’t necessary. A sloppy installation job will result in inadequate quantities of insulation and/or air leaks. Cellulose is comprised of loose recycled paper product and requires a blower to be installed (Note: blown-in cellulose is not the same as damp spray, dense-packed or netted cellulose insulation.) If you choose to do the project yourself, you’ll need to rent the necessary equipment and spend a little time learning how to use it properly.
Air leaks – Neither product is 100 percent resistant to air passing through it. However, inadequately installed insulation can cause gaps or pockets where air can penetrate your interior spaces. Also, since cellulose is a loose-fill product, any drafts or gusts of wind that can penetrate due to improper sealing will cause loose materials to blow around, compromising its insulating abilities.
