• Inspect the installation area and make any needed repairs before installing the Reflectix® Reflective/Bubble product.
• Check the basement ceiling to determine whether the joists are 16” or 24” on-center.
• Begin at one end of the house and staple the product to the top of the band board or the subfloor (also terminating this course in this fashion).
• Insert the 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.
• Finish the ceiling with the specified panel or sheetrock.
