Our take on the Double Reflective Insulation Roll for RV Windows

This is a roll of double-sided reflective insulation with a fiberglass core, sold for RV windows, ducts and similar spots where you want to block radiant heat. It works by reflecting heat back rather than absorbing it, so it is best used as a cut-to-size layer behind or over a window. At $23.99 at Walmart as of November 4, 2026, it is the only new price listed, so there is no recent range to compare against.

  • Cheap enough to cover several windows
  • Works for ducts as well as windows
Cons
  • Fiberglass edges can irritate skin and shed fibers

  • Thin roll, so it blocks radiant heat more than conducted heat
  • Not a finished window covering; looks utilitarian

Questions and answers

Is this worth it for RV windows?
Yes, if your main problem is sun heat radiating through glass. Cut panels to fit and tape them up; it is a cheap fix compared with custom shades.
Which side faces out?
Either side works because both faces are reflective. Face the shiny side toward the heat source, and leave a small air gap if you can.
Can I cut it to size?
Yes. Scissors or a utility knife cut it cleanly. Wear gloves and long sleeves, since the fiberglass core can irritate skin.
How do I attach it to a window?
It has no adhesive. Use double-sided tape, Velcro strips or a small frame. Tape the edges so fibers do not shed.
Does it stop heat or cold?
It reflects radiant heat, so it helps most against sun load on glass. It is thin, so it does little for conducted heat or overall insulation.
When is it cheapest?
The only new price listed is $23.99 at Walmart as of November 4, 2026. There is no other store price to compare, so watch for seasonal RV and camping sales.
Where is the Double Reflective Insulation Roll for RV Windows cheapest?
