Installing Fiberglass Insulation

Additional fiberglass insulation can help lower your utility bills in a major way. If you have the time and can do the work yourself, you’ll reduce costs even more. Here’s a quick overview of what you’ll need for this project.

Materials and Tools Needed

Tools you need for this job should be gathered and ready -a tape measure, straightedge, utility knife with fresh blades, and a stapler. Optional but handy to have tools would be- a long thin pole for pushing insulation into hard to reach areas, a stepladder, flat boards for sitting or standing in non-floored parts of the attic, flashlight or other portable lighting source.

Precautions

Fiberglass insulation may irritate exposed skin areas, so wear long-sleeved shirt, long pants, and light work gloves. Optional protection would be a respirator mask and safety goggles. Applying baby powder to all exposed skin areas before beginning will seal skin pore, preventing stray fiberglass particles from gettin in.

R-Value

Choose a thickness of insulation to achieve the suitable R-value. The R-Value designates insulating power or thermal resistance. The higher the R-value, the greater the insulating power. An online R-Value calculator to help you determine what level you need is available here. Also make sure the thickness will fit in the space available.

The fiberglass insulation Should remain in its packaging until you are ready to use it.

Position the insulation between joists, studs, and rafters, stapling it into place as you work.

In any open areas where thermal loss may take place, pack leftover scraps of insulation.

Cut the insulation as required as per the following; place it paper/foil side down, pressing strongly with the straightedge at the line you want to cut. Using utility knife, cut insulation, with straightedge as a guide. Cutting the insulation takes some practice, so be patient.

Use caulking to seal cracks or areas around windows and doors where ouside air may get through.

After installing, take a long shower, rinsing your entire body and shapooing your head. Wash the work clothes in a separate load.
