In many ways, blown cellulose insulation is the perfect balance of affordability and quality. It costs less than spray foam, and it is more durable than fiberglass. It often has a better overall R-value than fiberglass as well.
So what is cellulose insulation? Cellulose is made from treated paper fibers. Overall, it is a more environmentally friendly solution. This material slows down air flow and helps keep your home at the optimal temperature throughout the year. It maintains its R-value well for more than two decades in most cases. Overall, blown cellulose lasts between 20 and 30 years. Also, despite being partially comprised of paper, it is fire-resistant; this is because the cellulose is treated before it is applied.
Blown-in cellulose insulation may be right for you if you want a balance between affordability and overall quality. It is widely considered higher quality than fiberglass and more affordable than spray foam.
