Flexfoil is a low-e reflective insulation. It will help to keep your home warmer in the winter and cooler in the summer. This uniquely designed material reflects up to 97% of radiant heat back to its source. It works much like a thermos where hot liquids stay hot because the heat within the bottle is reflected back; cool liquids stay cool because the outside heat is reflected away. Approximately 50% to 75% of all heat loss in a home is due to radiant heat loss.


Flexfoil is a uniquely designed system of materials. The interior is made of one or two layers of insulating air bubbles. The outer surface is a sheath of 99% pure aluminum foil. Product is available with foil on one or two sides


Flexfoil can be used by itself or in conjunction with standard mass insulation materials. It will increase your home's efficiency along with raising comfort levels. The product is non-toxic, non-allergenic and pest resistant. Some typical applications include:

  • Hot water heaters
  • Garage doors
  • Pipes & ducts
  • Attics & crawl spaces
  • Basement walls & floors
  • Radiant Floors
  • Barns


Flexfoil is very easy to install. The only materials you will need are a staple gun, measuring tape, scissors, and Flexfoil seaming tape. No special clothing or breathing equipment is needed.
