If you join a crew, you'll be the "insulation guy," the "insulator," or simply "the one in the attic." What you actually do is make buildings comfortable and energy-efficient by installing the materials that keep heat in during winter, keep it out during summer, and muffle the sound between rooms. That might sound simple, but the job is surprisingly technical, and it's a lot more than stuffing pink fiberglass into a wall cavity.

Your core job is to install thermal and acoustic insulation on the interior surfaces of residential and commercial buildings. At a basic level, that means you're dealing with three main things: walls, floors, and ceilings. Each surface presents a different challenge.

In an attic, you might be blowing loose-fill insulation over the ceiling joists. In a crawlspace, you might be rolling fiberglass batts under the floor joists to keep the cold from seeping up through the wood. In an existing building, you might be drilling small holes into finished walls and blowing in dense-pack cellulose to retrofit insulation without tearing
