Sometimes batts can be difficult to put into small areas in the ceiling. There needs to be a surface for the insulation to rest on. Loose fill insulation is commonly made from fiberglass or cellulose. Fiberglass loose fill is similar to the fibers used to make batt or roll insulation.
Cellulose insulation is mostly made from recycled paper product. Spray foam insulation is an expanding spray that can be used to fill gaps and holes as well as walls and ceilings. Like blown in insulation you need to have a finished ceiling to apply it to use it.
The main things you will need are as follows:. Ceiling insulation is easy to install. It is a good DIY project for you and a friend. The process can be different for matt or roll insulation from blown in insulation. It is different for finished and unfinished ceilings. Lets take a look at how to install garage ceiling insulation. Look for window gaps or other holes. Use expanding spray foam insulation for this job. Before putting any insulation into the ceiling, install baffles or roof vents to maintain ventilation.
You need airflow in your roof to prevent moisture build up and mold. Foam baffles help maintain air gaps under the roof and that could be blocked by the insulation. Install the baffles near the edges of your roof where insulation might bunch up against the roof. You can install batt or roll insulation from the bottom and then finish it with drywall. You can install drywall and then use blown in loose fill insulation or batt insulation from the top. If your garage ceiling is already finished then you will need to insulate it from the top.
This means going into the attic and installing batt or roll insulation or blowing in loose fill. If you have an attached garage with a room above it, the builder may or may not have insulated the ceiling. Never in the history of the world have home builders cut corners. If the garage ceiling is finished and there is a room above with flooring you will have to decide whether you want to rip out the flooring or the garage ceiling to add insulation.
Pick out insulation that works with the joist gaps you have in your ceiling. Insulation is made to fit standard wall studs and ceiling joist dimensions. Look up local codes to see if you need to use faced insulation or unfaced insulation. Faced insulation has a paper or plastic vapor retarder layer on one side.
Batt or roll insulation is installed by pushing it through the ceiling joists. You pull it back down flush to the bottom of the joists. Butt the ends of the batts as close to each other as you can without scrunching up the insulation. For shorter joists near corners or walls, you may need to cut down the batt to fit. Cut the batt 1 inch wider than the joist gap. If required staple the facing to the sides of the joists every 8 to 12 inches. Check the local codes to see if this is required.
Expect to need cordless screwdrivers, cordless drills and a hammer. An A-frame ladder or scaffolding: Scaffolding is always a safer choice, but it can be a bit pricey for such a quick and easy job. Another option is to rent some scaffolding from your local big-box store. Safety goggles, gloves, and long-sleeve clothing: Regardless of which material you choose, itchiness and irritation are common side effects. I also recommend grabbing a safety mask to prevent fiberglass from entering your lungs.
Without it, mold and bacteria can form throughout the garage, including inside of the insulation. Fiberglass has a tendency to get caught in weird spaces! Locate all electrical boxes: Make sure that they have room to heat up without causing a fire hazard. There should be plenty of space around all wiring and other electrical parts. Install the vapor barrier by stapling it into place: Remember that the vapor barrier is just as important as the insulation.
If you overdo spray foam, you can cause gaps in the insulation. Most importantly, never allow gaps or spaces between any insulation. Common Mistakes As with any project, there are some common mistakes to watch out for: Mind the gap : Insulation needs a small amount of air to work properly. If you're turning the garage into living space or a full-time workspace and want to insulate the floor, one option is to use rigid foam covered in plywood or other subfloor material.
Check the fire rating on rigid foam; some types are not fire-resistant and are not suitable for exposed applications. Spray foam beyond the low-expanding canned product is excellent for both R-value and air sealing.
As a high-end material typically used for energy-efficient construction, spray foam may be overkill for most garage projects. But it might make sense if you're converting the garage to a living space.
Don't insulate your garage walls and ceiling without insulating the big garage door, too. Keep in mind that the structural metal ribbing of garage doors is an excellent conductor of heat, and this typically doesn't get insulated. As a result, the overall thermal performance of the door will be well below the rated performance of the insulation itself. Air sealing is particularly important with garage doors.
Create a seal along sides and top of the door with special garage door trim with an integrated weather-seal strip. Seal along the bottom of the door with a new rubber gasket, or "bottom seal.
