Reflective Aluminum Foil Double Layer Bubble Window Heat Insulation Wraps

1. Measure the metal roof to determine the amount of bubble foil wrap insulation required for the project. Purchase approximately 10 to 15 percent more product than required to account for overlapping and to provide the proper air gap between the purlins -- the horizontal lengths of wood that support the roof panels between the rafters.
2. Cover the metal roof purlins with double-sided adhesive tape. Unroll the foil wrap insulation and attach it to the first purlin. Continue to unroll the foil insulation and attach it to the remaining purlins, paying attention to allow the insulation to sag at least 1 inch between the horizontal members. The sagging provides an air gap that raises the insulation’s efficiency.
3. Continue to attach the aluminum foil bubble insulation to the metal roofing purlins, overlapping the adjoining sheets 2 inches as you go. This is a temporary hold to keep the bubble foil wrap in place while you prepare the next step.
4. Secure the bubble foil to the framing members with furring strips. Attach the furring strips perpendicular to the purlins every 24 inches to the framing members with 2-inch metal screws, paying attention to not disrupt the insulation’s sagging. Use a drill equipped with a screwdriver bit to drive the screws into the framing members.
5. Cover the seams of the bubble insulation with foil tape.
