Blown-In Insulation
Along with storage space, your attic provides a protective barrier against weather conditions. Insufficient insulation compromises comfort, air quality, energy efficiency, and safety. Unfortunately, 90% of homes lack proper attic insulation.
AJ Heating & Cooling specializes in loose-fill insulation and cellulose Sanctuary Insulation. The blown-in process is non-invasive, with no mess or damage to your home. The insulation effectively expands and conforms to fill every crack, corner, and odd-shaped crevice, creating an airtight barrier. Made from virgin fiberglass or recycled paper there are no chemicals or additives to aggravate allergies, and the result improves indoor air quality.
