Blown-in insulation is installed by using specialized equipment to “blow” loose fibers—typically cellulose or fiberglass—into attics, walls, or hard-to-reach cavities. The material fills gaps and voids more completely than traditional batts, creating a consistent thermal barrier that helps regulate indoor temperatures year-round. During installation, a technician feeds the insulation into a blowing machine, which breaks it up and delivers it through a long hose to evenly distribute it across the
