- Install R-19, un-faced, per manufacturer’s specifications.
- Place one corner edge of the Reflectix® in an upper corner of the stud cavity. Staple the product to the side of the stud (creating a 3/4” tab on the product and compressing into the fiberglass (3/4” as well)). The edge of the product should be flush with the forward corner of the stud.
- Proceed “down” stapling to the side of the stud every 2″- 3”.
- Repeat procedure on opposite stud.
- The Goal: Create a continuous 3/4” air space between the product and the interior panel.
- Finish wall interior.
