Bubble foil insulation keeps heat out in the summer and keeps heat inside in the winter. Foil reflective bubble insulation uses a combination of radiant barrier (reflective foil) along with a single layer of bubble insulation or a double layer of bubble insulation to reflect heat.
• Highly reflective foil insulates against radiant heat transfer - Stops 97% of radiant heat loss/gain
• Layer(s) of bubble provide r value to insulate against convective heat transfer
• Lightweight and easy to handle yet provides superior insulation
• Single Bubble Insulation is 3/16" thick（3-4mm）
• Double Bubble Insulation is 5/16" thick (6-8mm)
