Cellulose Insulation

Blown in cellulose insulation is made from recycled paper, and is sprayed into the wall cavities of your home, forming a seamless insulation system. It completely fills around obstructions, such as wiring and pipes, without leaving voids or gaps.

Due to its recycled content and higher energy and acoustic performance, cellulose is more environmentally preferred than fiberglass. At R-3.6 to R-3.8 per inch, cellulose insulation has about the same initial R-value as fiberglass batts but there’s two reasons that make is superior to fiberglass batt insulation.

A study compared fiberglass insulation and cellulose insulation in an attic. Both started at R-19, but fiberglass started to lose its effective R-value as temperatures dropped to just 32 degrees. It went on to lose up to 50% as temperatures continued to drop. Cellulose, however, not only maintained its R-value but it’s insulation effectiveness actually increased to more than R-20 as temperatures were lowered below -18 degree Fahrenheit. The other main reason we use it on our projects is because it can be applied to vertical surfaces and is a much better air sealer than batt insulation. Other benefits of cellulose insulation are fire retardancy, the absence of airborne glass fiber particles and good sound control.
