Insulating metal stud walls is similar to insulating walls constructed with wood studs. Batt insulation consists of fiberglass strands woven together to form a product with an "R" rating. The average "R" rating for fiberglass batts is between R11 and R38. A higher "R" rating results in lower energy costs.
Things You'll Need
- Batt insulation
- Utility knife
- Measuring tape
Measure the width between the wall studs. Most building codes require the gap between studs to be 16 inches.
Place the face end of the insulation roll between the metal studs at the top, leaving no gaps between the metal stud framing and insulation.
Unroll the insulation downward to fill the cavity between the metal studs. Press the insulation so it rests snugly between the studs.
Using a utility knife, cut off excess insulation that does not fit between the studs.
Custom-cut insulation pieces to fill any gaps between the studs. Areas to fill may include the perimeter of electrical outlets and small gaps around doors and windows.
Tips & Warnings
- Wear heavy gloves and a long-sleeve shirt to protect yourself from the fiberglass insulation and metal stud edges. Wear a mask to protect yourself from fiberglass inhalation.
