1. Installed with 3/4” Thermal Breaks
• Install Reflectix® Reflective/Bubble/Bubble/Reflective, Staple Tab product vertically, using 1/2” self tapping screws. This will secure the insulation to the exterior of the C or Z girts.
• Tape the seams with a Reflectix® Foil Tape (goal is an air-tight, snug seam seal).
• Install a 3/4” thermal break and attach corrugated metal exterior finish.
• If an interior finish is applied, install the interior panels to the interior face of the girts. This will create a 3/4” air space between the exterior finish and the insulation and an 8” air space between the insulation and the interior finish.

2. Installed with a 3/4” Drape in Product (No Thermal Break)
• When installing the product, insure there is a drape (towards the interior) of at least 3/4” at the center of the cavity.

* Includes thermal resistance of 1.70 interior air film.
