installing Reflectix

1. Product (Double Layer) Installed to Underside and Inside of Floor Joist - R-21 and a Radiant Reflector

• Begin at one end of the house. Insert the first course of Reflectix

half way up into the joist cavity and

staple (at approximately 3” to 4” intervals) the edge of the product to the side of the joist. The goal is to

split the joist cavity into two approximately equal enclosed air spaces.

• Continue with the second course of product at one end of a joist cavity (after the first course has been

installed) and secure the product “end” with staples to the sub-floor or band board. Proceed down the

joists by stapling each edge (or middle of the Reflective/Bubble/Bubble/Reflective 48” wide product) to

the face of each joist. Staple the product at intervals of approximately 3” to 4”. Enclose the entire joist

run(s).
