Our take on the Single Bubble Reflective Insulation (White/Foil) 4'x125' - 500 sq ft

EcoFoil Single Bubble is a thin radiant barrier: one layer of polyethylene bubbles bonded between a white face and a foil face, about 1/8 inch thick. It blocks radiant heat and the bubble layer acts as a built-in air gap, which helps limit condensation and frost where temperatures differ sharply on each side. The white side faces the finished room for a cleaner look. It suits pole barns, metal buildings, basement walls, crawl spaces and storage units in moderate climates. Compared with fiberglass batts or foam board it adds far less bulk and R-value, so it works best as a radiant barrier and vapor-side layer rather than a stand-alone insulation.

About the Single Bubble Reflective Insulation (White/Foil) 4'x125' - 500 sq ft

EcoFoil Single Bubble Reflective Insulation combines a solid radiant barrier with a layer of polyethylene bubbles. The bubbles act as a built-in air gap that reduces contact between the temperatures on either side of the material. The bubble layer also helps combat frost and condensation when the temperature difference between the two sides is extreme.

It is used in pole barns, metal buildings, basement walls, crawl spaces and storage units in moderate climates. The material is very thin, lightweight and installs easily with minimal equipment. The white/foil version has a white finish that faces the finished space, giving a more finished look.

All seams must be taped so the insulation acts as one sheet and keeps its moisture barrier. It is not for under slab applications because the radiant barrier is exposed.

Questions and answers

Is this enough insulation for a pole barn on its own?
No. It is a radiant barrier with a bubble air gap, not bulk insulation. In moderate climates it works well over framing or combined with existing insulation.
Which side faces the room?
The white side faces the finished space; the foil side faces the outside or the cavity. This gives a cleaner interior look.
Do I have to tape the seams?
Yes. Taping every seam is required for it to act as a continuous barrier and control condensation.
How thick is it?
About 1/8 inch. That thin profile lets it fit behind siding, in crawl spaces and over framing without stealing space.
Can I cut it with a knife?
Yes. A utility knife or heavy scissors cuts it cleanly, and it is light enough to install alone.
Is it good for cold climates?
It is intended for moderate climates. In extreme cold, pair it with bulk insulation rather than relying on it alone.
