Use of fiberglass insulation for insulating ducts has resulted in unintended distribution of fiberglass fibers and growth of molds and mildew.

Method 1 Lineal Duct Wrap
Method 2 Spiral Duct Wrap

PRODUCT SOLUTION: TVM eFoil Foil/Double Bubble/Foil

• For Methods 1 & 2: Use eFoil, Foil/ Double Bubble/Foil (2220-48-125) 48" Width.

PRODUCT DESCRIPTION:

• TVM eFoil Duct Foil is a double layer of Polyethylene bubbles bonded to and sandwiched between two different radiant barrier aluminum foil sheets.

PRODUCT EFFECTIVENESS:

• eFoil Duct Foil is clearly effective, safe and very easy to install when compared to fiberglass insulation.

PRODUCT INSTALLATION:

• Method 1
  
  • 1) Fasten eFoil 2" strips around the duct with rFoil 2" tape. By placing these strips every 2 to 3 feet, you create the airspace needed to achieve optimum R-values (R-6.2).
  • 2) Wrap Bubble Barrier rFoil around the duct.
  • 3) Tape it in place and tape all adjoining seams.

• Method 2
  
  • 1) Wrap the duct using 12" wide pieces of Bubble Barrier eFoil. Overlap each layer 1" and do not leave any open space or exposed duct.
  • 2) Fasten the end with rFoil Tape.

BUILDER'S NOTE:

• All tape should be applied using a flat-edge taping tool to ensure good adhersion.
