Insulate Garage Ceiling Rafters

Garages are not the most insulated part of a house. In fact some aren't insulated at all except along the wall that connects with the house. If you are planning to use your garage to store things that need to be kept at a certain temperature, or you are going to locate a workshop in it, then insulating the space will help you maintain a comfortable environment. One of the places that makes the garage so hot or cold is the roof. Insulating the rafters along the roof line will reduce the heat transfer.


Instructions


1. Connect scaffolding to reach the ceiling. This is needed if there are no joists across the ceiling at a lower level that you could walk on. If there are ceiling joists, place a few plywood sheets across the beams to give you a platform to walk on.








2. Locate any electrical or other objects on the rafters that could cause a fire hazard. Cut 2-by-4s to match the width between the rafter beams. Use 3 inch screws to connect the 2-by-4s in between the beams at a perpendicular angle on either side of hazardous objects. Drill the screws through the rafter beams and into the ends of the boards.


3. Measure the length of the space along the roof between the rafter beams from the peak to a few inches from the floor. If you put 2-by-4s in place, measure the space down to the board.


4. Spread batting out that has a vapor barrier on one side. Cut it to match the length you measured using a sharp blade knife.


5. Place the batting in the space between the beams with the vapor barrier facing the ceiling.


6. Staple the batting to rafter beams with a staple gun. Locate the tabs on the side of the batting and staple through them and into the wood. Continue filling in the spaces until all the places between the rafters are filled.
