Our take on the SmartSHIELD Reflective Foam Core Insulation Roll

SmartSHIELD is a foil-faced polyethylene foam roll used as a radiant barrier, vapor barrier and sound barrier. It reflects about 95% of radiant heat, carries a Class A / Class 1 fire rating and is waterproof and mold resistant. The 24 in x 50 ft roll is listed at $129.95 at Insulation MarketPlace as of November 4, 2026, the lowest of two stores pricing it new.

Best forAttics and roof decks where radiant heat is the main problemGarage doors, sheds and metal buildingsBasement and crawlspace vapor controlDIY buyers who want to cut and staple their own panels
Pros
  • Reflects about 95% of radiant heat with low emissivity of 0.04
  • Acts as vapor barrier and sound barrier in one layer
  • Class A / Class 1 fire rating
  • Light and easy to cut with a knife or scissors
  • Waterproof and resistant to mold growth
Cons
  • Thin foam gives little conductive R-value on its own; the high R figures assume an air gap
  • Foil surface tears and creases if handled roughly
  • Tape and seams need care to keep the vapor barrier continuous
  • Not a substitute for batt or blown insulation in cold climates

Questions and answers

Is the SmartSHIELD roll worth it?
It is a good value if you need a radiant and vapor barrier over an air gap, such as under a roof or behind a garage door. It is not a replacement for thick bulk insulation in cold climates.
What R-value does it really deliver?
The foam itself is thin, so most of the performance comes from the reflective surface and the air space next to it. The advertised R-value of up to about 15 to 20 depends on that gap being installed correctly.
Can it be used in a basement or crawlspace?
Yes. It is waterproof and works as a vapor retarder, so it suits crawlspace walls and rim joists. Tape the seams so moisture cannot get behind it.
Is it fire rated?
Yes, it carries a Class A / Class 1 fire rating. Check local code for how it must be covered or left exposed in your space.
What sizes are available?
Rolls come in several widths and lengths, including 48 in x 25 ft, 48 in x 50 ft and 500 sq ft rolls. Confirm the width you order matches your joist or stud spacing.
When is the best time to buy?
The best price seen is $129.95 at Insulation MarketPlace as of November 4, 2026. Compare both stores before ordering, since only two list it new.
