Our take on the Reflective Foam Insulation Heat Thermal Shield Radiant Barrier 4 x 10 Defects

This is a 4-by-10-foot roll of double-sided reflective foam radiant barrier sold by Everbilt, rated for contact temperatures from -60°F to 180°F. It reflects radiant heat rather than slowing conductive heat, so it works best as an attic, wall or floor barrier with an air gap. The listing is for factory-defect stock, which is why it is cheap. At $11.97 at The Home Depot as of November 4, 2026, it is at the low end of its recent range; only two stores price it new.

Questions and answers

Is the defect version worth buying over a first-quality roll?
Yes if the flaws are cosmetic and the roll goes in an attic or shed where looks do not matter. Check the roll on arrival, since creases and dents can affect how flat it lays.
Does it actually lower heating and cooling bills?
It blocks radiant heat transfer, which helps most in attics and under roofs during summer. Savings are modest unless it is installed with a facing air gap and paired with bulk insulation.
Can it go directly against a wall or ceiling?
It can, but performance drops sharply when the foil touches a solid surface. Leave a small air space on at least one reflective side for the radiant barrier to work.
What is the temperature and moisture rating?
Contact temperature range is -60°F to 180°C, and water vapor transmission is 0.02 perms, so it acts as a vapor retarder. Do not use it where building code requires a specific insulation R-value.
What comes in the 4 x 10 roll?
One roll covering 40 square feet, 4 feet wide by 10 feet long. Tape, fasteners and staples are not included.
When is it cheapest?
Defect stock like this is already discounted; the best price seen is $11.97 at The Home Depot as of November 4, 2026. Watch for seasonal insulation sales in fall and spring.
