US Energy Products 5mm Reflective Foam Core Insulation Roll - 24'' X 50ft Radiant Barrier

This is a 24-inch wide by 50-foot long roll of 5mm thick reflective foam core insulation from US Energy Products.

It's a radiant barrier, meaning it reflects heat away, which can help keep your space cooler in the summer and warmer in the winter.

The foam core gives it some rigidity while still being easy to cut and install.

Great for use in garages, attics, workshops, or even for wrapping around water heaters.

It's brand new and still sealed in the original packaging.

The manufacturer part number is simply 5mm Thick.
