Installation Instruction pdf: MB1 Roof Retrofit Revised 012021
- The Reflectix® Insulation is installed with the “white side” towards the interior of the building.
- Pre-installation inspection – Check the roof area for clutter, water sprinklers, conduit and lights. Sprinkler systems are especially important. All water pipes must be below the Reflectix® Reflective/Bubble/Bubble/White Insulation to prevent the possibility of freezing in the winter. In many instances the Reflectix® 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.
- Attach the product using 5/16” staples at approximately 4” intervals.
- Staple the edges of the Reflectix® Reflective/Bubble/Bubble/White product to the furring strips with a 3/4” overlap at the seams.
- Tape the seams with a Reflectix® White Poly Tape (goal is an air-tight, snug seam seal).
- Staple product down the middle of the sheet into the furring strip above.
* Includes thermal resistance of 0.61 UP and 0.92 DOWN for interior air film.
Calculation Disclaimer: All values are calculated based on the “ASHRAE Handbook of Fundamentals” heat flow up and down.
