This unique twinwall bubble insulation can drastically reduce your greenhouse heating costs by as much as 45%. In addition to saving you money during the cool seasons, it will also help prevent overheating during the hot summer months. This unique bubble is only 3/16" thick but provides 15% more insulation than other bubble over twice as thick because of the extra outer layer that traps more air inside. Our bubble insulation has clear bubbles for better light transmission, and a reinforced backing for longer life. Works well with all types of greenhouse coverings. Shown installed with bubble clips. For best results, tape sections together with the greenhouse poly tape shown above. Bubble should be installed on the inside of the greenhouse.


  • Twinwall construction provides 15% more insulation than other bubble over twice as thick
  • Oversized 4 1/2' width allows for easier install in greenhouses using 2' or 4' wide panels
  • R-value: 1.4
  • Light transmission: 80%

Very durable

Used in our porch for the winter as a thermal barrier and it was a very quick and painless install. We felt the temperature difference immediately.

Easy to Install. Highly Recommend!!!

This was perfect as an insulator to my greenhouse. Propane tanks have been lasting about twice as long since installing it. This stuff will pay for itself in no time!
