Open Interior with 3/4” Thermal Breaks • After the red metal is erected, install the Radiant Bubble product over the purlins by using 1/2” self-taping metal screws and screwing the product to the purlins. 1.  Radiant Bubble Insulation 2.  Exterior Roof Panel 3.  3/4” Thermal Break 4.  Purlin 5.  Red Metal (Structural  Frame) Tools Required: Safety Glasses Tape Measure Utility Knife Screw Gun radiant barrier roof installation save money with radiant barrier in roof 2 1 3 5 4 • Tape the seams with Foil Tape (goal is an air-tight, snug seam seal). Install at least a 3/4” thermal break. If installing a standing seam roof, use clips with thermal breaks. Install roofing either by screwing corrugated metal screws through the thermal break and insulation to the purlin or install a standing seam roof. If an interior finish is to be installed, attach to the bottom of the purlins. This will create a 3/4” air space between the roofing and the insulation and an 8” air space between the insulation and the interior finish. 2. Open Interior without Thermal Breaks and a Nominal 3/4” Drape • Per instructions above without the thermal break. * Includes thermal resistance of 1.32 UP and 4.55 DOWN for interior air film.

Sprinkler systems are especially important. All water pipes must be below the Radiant Bubble to prevent the possibility of freezing in the winter. In many instances the Radiant Bubble product must be installed up near the roof deck. Install 1”x 2” furring strips on the bottom of and perpendicular to the Z purlins on 22” centers. Utilize 1 1/4” self-taping sheet metal screws to secure the furring strips to the Z purlins. Butt the furring strips together and tape. Staple tape for reinforcement. Staple the edges of the Radiant Bubble Staple Tab product to the furring strips with the 3/4” tabs (so that they will overlap at the seam). Tape the seams with Foil Tape (goal is an air-tight, snug seam seal). Staple product at approximately 4” intervals down the middle of the sheet into the furring strip above. * Includes thermal resistance of 1.32 UP and 4.55 DOWN for interior air film.

Check the area you are insulating and make any repairs needed.  Worn wiring should be replaced. Make sure the work area is well ventilated and well lighted. Use eye protection. Use caution and common sense. Do not work in the attic when it is too hot. Stapling into a wire can cause electrical shock and death. Wear sunglasses when installing reflective foil insulation on sunny days. Be careful when working with large pieces of reflective insulation on windy days.
