Bubble Foil Insulation
24" x 125' Between Joist Insulation w/ Staple Tabs Foil/Double Bubble/Foil (250 sq. ft.)
Specifications
EcoFoil Floor Joist Insulation is engineered to reduce radiant heat transfer and help prevent condensation in floor and wall cavities. Built with two layers of polyethylene bubbles bonded to reflective metalized surfaces, this 1/4"–5/16" thick insulation delivers 96% reflectivity and just 4% emissivity—meaning only a small fraction of radiant heat passes through. Instead of slowing heat movement like traditional insulation, it reflects heat away from the surface to improve comfort and energy efficiency. When seams are taped, it also serves as a vapor barrier to help protect framing materials from moisture and mold.
This 24" wide insulation is designed to fit standard 24" on-center floor joists or studs. Lightweight and easy to handle, each piece includes 3/4" staple tabs on both sides for fast, secure installation.
High-Reflectivity Insulation for Joists & Wall Cavities
Floor Joist Insulation is ideal for applications where radiant heat reduction is needed beneath floors, in basement ceilings, or in utility areas. Its double-bubble structure creates an insulating air layer while the reflective surfaces direct heat away from the building envelope. This makes it an effective complement to traditional insulation in areas requiring improved thermal control.
Lightweight, Easy-to-Install Design for 24" On-Center Framing
The pre-sized 24" width fits standard framing without trimming, and the integrated staple tabs simplify installation. The material is clean to handle, flexible enough for tight spaces, and durable enough to resist tears during installation or maintenance.
