Our take on the Double Bubble Reflective Insulation Kit with Tape and Adhesive 20.5 x 54 in, 16 Pieces

This is a 16-piece kit of double-bubble reflective radiant barrier panels, each 20.5 by 54 inches, with tape and adhesive included. The foil-faced bubble core blocks radiant heat rather than slowing conductive heat, so it suits attics, garages, and other spaces where you want to cut summer heat gain or hold warmth near a surface. The kit is a one-store item: $154.98 at Walmart as of November 4, 2026, with no other new-price listings to compare against.

Pros
  • Tape and adhesive included, so no extra fasteners to buy
  • Light and easy to cut with scissors or a utility knife
  • Foil surface reflects radiant heat and resists moisture
  • 16 panels cover about 123 square feet total
  • No framing needed for stapled or glued installs
Cons
  • Only one store lists it, so there is no price competition
  • Bubble barrier does little for conductive heat loss without an air gap
  • Foil facing can tear and is unforgiving if stapled poorly
  • 1 in thickness is thin compared with rigid foam board

Questions and answers

Is this kit worth it compared with rolls of bubble foil?
Buy the kit if you want the tape and adhesive bundled and a panel size that fits between rafters. Rolls are usually cheaper per square foot, but you supply your own tape and cut more.
How much area does 16 pieces cover?
Each panel is 20.5 by 54 inches, about 7.7 square feet, so the full kit covers roughly 123 square feet before overlaps and waste.
Does it need an air gap to work?
Yes. Reflective barriers perform best with a facing air space; pressed flat against a surface, the foil loses most of its radiant benefit.
Can I use it in a garage door?
Yes, it is a common use. Cut panels to fit the door sections and glue or tape them in place, foil side facing the open space.
When is the price lowest?
At $154.98 at Walmart as of November 4, 2026, it is the only new listing, so there is no lower price to wait for right now.
Where is the Double Bubble Reflective Insulation Kit with Tape and Adhesive 20.5 x 54 in, 16 Pieces cheapest?
At Walmart, for $154.98, as of our latest check.
