R-3.7, R-7.0 and a Vapor/Moisture Barrier
Note: Installation instructions and illustrated drawings are recommendations only, while proper local construction methods are the responsibility of the installer.
The Do-It-Yourselfer has several options to choose from when finishing a Masonry Wall. Reflectix® provides three such options that do not require the addition of a stud wall. The structure of the masonry wall is utilized to support the system. The product is easy to install and contains no fibers or dust that would require respirators or protective garments.

There are Two “Levels of Benefit” Options
1. R-3.7 (1”x 2” nominal furring)
- Attach 1”x 2” (nominal) furring strips vertically at an interval of 16” on center to the masonry wall (with an adhesive or fastener that is specified for this application).
- Cut the Reflectix® Reflective/Bubble/Bubble/Reflective, Staple Tab product (using scissors or a utility knife) into lengths equal to the height of the wall (floor to ceiling).
- Staple the product to the face of the furring strip – product seams should split on a furring strip.
- One air space is created between the Reflectix® and the masonry wall.
- Finish with interior panel (or sheetrock) of choice.
2. R-7.0 (2”x 2” nominal furring)
- Same as above, except the product is not stapled to the face of the furring strip.
- Staple the product to the side of the furring strip at a depth of 3/4”. The goal is to split the cavity (in two) into approximately equal air spaces.
- The two air spaces created are: one between the Reflectix® and the masonry wall, and the other between the new interior panel and the Reflectix®.
