With the right tools, garage insulation can be a painless process. Befor you begin, you need to decide on the type and grade of insulation (R-value) you want to use. There are two types of insulation you can use, spray cellulose (loose fill) or batts. If the garage is unfinished, batt insulation works well because it comes in precut sections. Keep in mind that the higher the R-value, the more heat the insulation traps. Lower R-values are often used in walls as a noise reducer, instead of a heat insulator. 

    Step 1 – Safety First

    Before you begin, it is important you protect yourself from the fiberglass in the insulation. It can irritate the skin, eye and even the lungs, if breathed in. Use safety glasses, a dust mask and wear a long-sleeve shirt and pants. 

    Step 2 - Prepping the Area

    If your garage is unfinished, clean the walls where the insulation will be added. A broom will remove cobwebs, dirt and debris. If your garage has finished walls (interior sheetrock walls), you will need to remove the sheetrock first. You can remove the sheetrock safely by using clean lines to remove the walls. If there is damage caused to the sheetrock, you can replace it easily by buying another sheetrock tile at your local home improvement store. Typically, the cost of sheetrock is inexpensive.

    Step 3 – Hanging the Insulation

    Using a low R-value insulation of the batt type, take a section of batt insulation and hold it against the top of the wall.  Use a ladder as needed.  Strike the insulation with the hammer stapler. Place a staple on either side at the top.  A couple feet down, place another set of staples on either side.  Continue down until you reach the end. If the wall is an exterior wall that has masonry, you won’t be able to sink the staples into the rock. Instead, you will need to attach the insulation’s paper to a wooden stud on the right or left side with staples.

    Step 4 – Cutting the Insulation

    Use the tape measure to determine the length of the cut. Then, measure the same distance on the insulation. Use a marker to note its position. Take the straight edge and hold it next to your mark. Use the razor knife, cutting alongside the straight edge. Once cut, hang the cut pieces as you would the full-length ones.  Hold them in position and use the hammer stapler to secure them to the wall

    Step 5 – Finishing Up

    Once all the insulation is attached, you’re finished. If you have any full-length pieces left, you can add them in other rooms. For example, the attic, because it can usually use additional insulation. Use caution when removing your safety equipment, so that you do not to come in contact with the fiberglass.
