Our take on the Double Bubble Insulation

Double Bubble insulation is a reflective foil product with two layers of bubbles trapped between reflective surfaces. The trapped air pocket slows radiant heat transfer and helps cut condensation in garages, sheds, doghouses, vehicles and RVs. It is a low-cost way to take the edge off heat and cold in spaces you don't fully condition. It is not a substitute for thick batt or foam insulation in a heated living space, and seams need insulation tape to form a vapor barrier.

Best forGarages, sheds and workshopsDoghouses and animal sheltersRV and vehicle interiorsQuick radiant barrier over framing or sheathing
Pros
  • Reflective foil on both faces blocks radiant heat
  • Bubble core adds a trapped air pocket
  • Light and easy to cut and fit
  • Helps reduce condensation when seams are taped
  • Works in tight spaces where batt insulation won't fit
Cons
  • Low R-value compared with foam board or fiberglass batts
  • Needs insulation tape at seams to act as a vapor barrier
  • Thin foil can tear or crease during handling
  • Little benefit against conducted heat without an air gap

What reviewers say

  • 4.9 / 5216 ratings

Buyers rate it highly, mostly for sheds, garages and animal shelters where a thin reflective layer is enough. They like how easy it is to cut and install and say it takes the bite out of summer heat. Complaints center on the low insulating value and on seams that need taping.

About the Double Bubble Insulation

Double Bubble insulation is used to manage radiant heat and insulate confined spaces such as garages, sheds, doghouses, vehicles, and RVs.

It has a dual-layer design that creates an air pocket. The air pocket blocks the transfer of hot and cold temperatures through the material. It also reduces condensation build-up in various climate conditions.

To create a vapor barrier, seal the seams with insulation tape.

Questions and answers

Does double bubble insulation replace fiberglass or foam insulation?
No. It is a radiant barrier with a small trapped air pocket, so its R-value is low. Use it as a supplement or in spaces like sheds and garages that aren't fully conditioned.
Do I need to tape the seams?
Yes, if you want a vapor barrier. Sealing seams with insulation tape closes the gaps and helps control condensation.
Where can I use it?
Garages, sheds, doghouses, vehicles and RVs are the common uses. It also works over framing or sheathing as a radiant barrier.
Does it help with condensation?
It can reduce condensation buildup when seams are sealed, because the reflective surface and trapped air limit temperature swings across the material.
Can I cut it to size?
Yes. It is light and cuts easily with a utility knife or heavy scissors, which makes fitting odd spaces simple.
Where is the Double Bubble Insulation cheapest?
At EcoFoil, for $45.00, as of our latest check.
