2290 Direct Wrap for an R-4.2 Value (Without Spacer Strips)

1. This method does not require spacer strips. However, it is recommended that the product be loosely wrapped around the duct (for an R-4.2 value).
2. Determine the exact perimeter around the duct.
3. For optimal performance, wrap the duct with material length that is approximately 5% longer than the actual duct perimeter. Ensure that the printed Code Certification Strip, taped the entire length of the roll, is facing out. This information must be visible to inspectors.
4. Installed loosely, this will create small airspaces between the outer duct wall and the insulation. These pockets of air will enhance the thermal value of the system.
5. Tape all seams and joints using rFOIL Metalized Tape, specially formulated to adhere to rFOIL Duct Insulation.
– Item Code 15112 (2” x 150′)
– Item Code 15113 (3” x 150′)
– Use of any tape other than the rFOIL items above will void the manufacturer’s warranty.
6. Repeat the above steps for the entire length of the ductwork.

2290 Direct Wrap for an R-6.0 Value (With Spacer Strips)

1. Create spacers by attaching 2” wide strips of rFOIL Duct Insulation (spacers also sold separately). Spacers should be wrapped around the perimeter at approximately 2′ intervals.
2. Wrap rFOIL insulation around the duct with spacers and pull hand-tight (for an R-6 value). Ensure that the printed Code Certification Strip, taped the entire length of the roll, is facing out. This information
must be visible to inspectors.
3. Tape all seams and joints using rFOIL Metalized Tape, specially formulated to adhere to rFOIL Duct
Insulation.
– Item Code 15112 (2” x 150′)
– Item Code 15113 (3” x 150′)
– Use of any tape other than the rFOIL products above will void the manufacturer’s warranty.
4. Properly installed, the spacers will provide a consistent airspace around the duct.
5. Repeat the above steps for the entire length of the ductwork.
