Fiberglass Batt Insulation in Detroit: what to expect
Fiberglass batt insulation in Detroit is the standard choice for open stud walls, floors over garages and crawl spaces, and new additions or gut remodels. When walls are opened in older homes in Detroit, Grosse Pointe, Royal Oak and Canton, batts are the most common way to insulate before drywall goes back up.
Batts only perform when they are installed carefully: cut tight around outlets and boxes, split around wires instead of compressed behind them, filling the full cavity with no gaps or voids. Kraft-faced batts or a separate vapor retarder go on the warm side of the wall as the code requires for our cold climate. Mineral wool batts are an alternative with better fire and sound resistance.
For closed walls, blown-in insulation is usually the better fit. Pair batts with air sealing, or compare Metro Detroit insulation contractors.

Permits and licensing in Michigan
Batts are usually installed as part of an addition, remodel or new build that has a building permit, and many municipalities inspect insulation before drywall covers it. In Detroit that is BSEED; elsewhere confirm with the local building department. If walls in an older home are being opened, ask whether any existing materials should be tested for asbestos first.
Paid residential insulation work above a threshold set by state law requires a LARA license: a Maintenance & Alteration Contractor license that lists Insulation, or a Residential Builder license. Check the number on the LARA lookup.
