Cellulose insulation is made from recycled newsprint and other recycled paper, and treated with nontoxic fire retardants, cellulose insulation has been a tried and true method of insulating homes for decades. Its excellent sound insulating properties, its ability to provide an effective 1-hour fire rating, high R-value per inch, and industry leading environmental properties, makes cellulose a perfect choice for insulating attics and sidewalls.
Properly insulating and air sealing your home is one of the quickest, easiest, most cost effective steps you can take to immediately reduce your heating and cooling bills and help preserve the environment.
Using a long hose that’s connected to a blowing machine, insulation is directed into a wall cavity or attic, filing the cavity or blanketing the space. To achieve the desired R-value, install the amount specified on the coverage chart printed on the bag. (Cellulose insulation coverage charts are developed to take into account any settling of the material, so following the directions will yield the desired R-values.)
In new homes, cellulose can be applied dry, either blown-in behind a fire-rated synthetic membrane that is stapled to the studs, or damp-sprayed by an installer using a specialized spray truck. (Even though there is a small amount of water added to the material during this process, the insulation dries quickly and meets all ASTM requirements for preventing mold.)
GOOD JOB on Kimball Lane, Cambridge.
We did the Stretch Code Thermal Inspection and Blower Door test and your work is well done.
Please call my cell number so we can talk. I would like to be able to recommend you to our other builder clients, because your work is so easy to inspect!
