How to Install Fiberglass Insulation
Adding insulation can cut your utility bills significantly. Most homeowners can do the work themselves, reducing the costs of the project.
- Make sure that you have the necessary tools ready - tape measure, straightedge, utility knife (with new blades), and a squeeze-type stapler.
- Consider having the following items available - a pole for pushing insulation into roof rafters and other hard to reach areas, stepladder, boards (for sitting or standing in attic areas with no floor), portable lighting source.
- Wear a long-sleeved shirt, long pants, and work gloves - insulation can irritate bare skin.
- Select an insulation of the appropriate thickness to achieve the R-value you want (R-value is a measure of insulation's effectiveness) and that will fit in the available area.
- Leave fiberglass insulation in its packaging until you are ready to use it.
- Place the insulation between studs, joists, and rafters, stapling into place as you go.
- Stuff scraps of insulation in any open areas where heat loss may occur.
- Cut insulation as necessary by placing it paper/foil side down and pressing firmly with your straightedge where you want to cut. Use your utility knife to cut the insulation, using the straightedge as a guide.
- Go back and caulk any cracks or areas around windows and doors where drafts can get through.
