Welcome to Flexfoil

Multipurpose insulation for residential and commercial applications. Product is comprised of 2 layers of polyethylene bubble that are sandwiched between 2 layers of 99% pure aluminum foil. The polyethylene encapsulated air bubbles serve as an effective thermal break as well as vapour barrier, while the two outer layers of aluminum reflect up to 97% of all of the radiant energy.

*This product also available in a Foil Single Bubble Foil format.

What you should know about R Values
The chart shows the R-Value of this insulation. R means resistance to heat flow. The higher the R-Value, the greater the insulating power. Compare insulation R Values before you buy. There are other factors to consider. The amount of insulation you need depends mainly on the climate you live in. Also, your fuel savings from insulation will depend upon the climate, the type and size of your house, the amount of insulation already in your house, and your fuel use patterns and family size. If you buy too much insulation, it will cost you more than what you'll save on fuel. To get the marked R-Value, it is essential that this insulation be installed properly.
