16" wide x 125ft long (166 sqft total) roll or reflective bubble insulation by rFoil. Designed for installation between the 16" OC (On Center) joists, this insulation offers excellent R-value, provides a water vapor barrier and is overall a much healthier alternative to fiberglass insulation. It is Class A/1 fire-rated and is suitable for projects with or without PEX radiant heat (where PEX tubing is stapled to the bottom of the subfloor/plywood).
Insulation has 1" side tabs which make stapling easier. For optimal performance, use with rFoil 2" wide metalized tape #15012 or similar.
