Spray foam insulation does a great job of preventing energy loss with higher R-values than typical insulation products provide, and with it's air-sealing qualities, it improves overall air quality by stopping dust, pollen and other allergens from entering the home. Another benefit is how it stops conditioned and unconditioned air from meeting behind walls where mold and mildew occurs from condensation which destroys homes from within.
Dense packing cellulose is an effective and inexpensive retrofitting option to improving insulation values in existing homes. The cellulose is installed dry at 3.5 lbs. per cubic ft. through the exterior sheeting in most cases providing improved comfort, reliable air sealing to stop dirt, dust, pollen and other allergens from entering the home. Cellulose offers a class 1 fire rating and superb noise reduction capabilities.
