Insulation for Block or Masonry Wall

Installation Instructions: (There are 3 “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 InfraStop® 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 InfraStop® and the masonry wall.
• Finish with interior panel (or sheetrock) of choice.

R-4.2 (2”x 2” nominal furring)

• Same as above except utilize 2”x 2” (nominal) furring.

R-6.1 (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 InfraStop® and the masonry wall, and the other between the new interior panel and the InfraStop®.
