Product details:

Double Bubble reflective insulation offers a smart solution for reflecting radiant heat and insulating smaller spaces such as garage doors, sheds, doghouses, vehicles, RV's, and much more. Its double layer of bubbles creates an air chamber that helps eliminate condensation, which is a common problem when temperatures are cold on one side of the product and warm on the other. Easily create a vapor barrier by sealing the seams with insulation tape.

Fast, easy installation
Thin, lightweight bubble foil insulation makes it easy to handle and install in your building’s walls, roof, and ceiling. Cut the foil insulation to size using a utility knife and seal up the seams using insulation tape.
Efficient temperature control
EcoFoil Double Bubble Insulation reflects up to 96% of radiant heat away from your home in warm, summer months. In winter, it reflects warm air back inside your building to increase energy efficiency and maintain comfort year-round.
Improves performance of traditional insulation
While double bubble foil insulation has little to no R-value, its reflective properties contribute to the overall effectiveness of fiberglass or spray foam insulation.

Frequently Asked Questions

Should I choose Single Bubble or Double Bubble Reflective Insulation?

Generally speaking, you should install Double Bubble in colder, extreme climates with cold winters (Northern US). Double Bubble Reflective Insulation will help prevent the formation of frost and condensation when temperatures are very cold on one side of the material, and warm on the other. The larger these temperature differences are, the greater the risk of condensation. If you’re not as concerned about condensation, Single Bubble Insulation could work for your application.

What do the bubbles do?

The layer of bubbles provides a thermal break between hot and cold air, and helps eliminate condensation from forming in your structure. Double Bubble has two layers of bubbles for extra condensation prevention. Double Bubble Reflective Insulation is typically used in the northern states where temperature differences inside vs. outside your structure are extreme, typically during cold, frigid winters.

How much tape do I need?

1 roll of tape will be needed for every 500 sq ft of reflective insulation. It's important to tape the seams between adjoining sheets—never use tape to attach the product directly to your structure. Taping the seams creates a vapor barrier when installed properly, and helps ensure the reflective properties of the insulation.

Which tape do I choose?

For Foil/Foil finishes, choose Metalized Reflective Insulation Tape
For White/Foil finishes, choose White Reflective Insulation Tape

Should I choose a white finish or a foil finish?

Some customers prefer the white finish as a visual preference. Both White and Foil finishes reflect radiant heat equally well.

How do I install Double Bubble Insulation?

Installation methods will vary, depending on your application. If your structure has exposed studs, the material can be stapled with a staple gun. If you have nothing to staple the product to, choose a spray adhesive like Spray-Lock Multi-Purpose Eco-Friendly Spray Adhesive. More information on installation methods can be found under the "Shop by Application" tab in the main menu at the top of this page.
