Consist of one or two layers of air bubble sandwiched between layers of aluminum of foil.

Characteristics:

The bubble contains an air retention layer designed to provide increased strength and puncture resistance and provide a greater reduction of heat transfer.

The aluminum foil is an effective barrier against moisture,air currents and vapors.

Aluminum foil reflective insulation,which can reflect up to 97% of the radiant energy that strikes it,has proven to be an outstanding radiant heat barrier.

Keep summer heat out and winter heat in so to help keep house cool in the summer and warm in the winter.
