OWENS CORNING VAPORWICK FIBERGLASS PIPE INSULATION

  • Innovative new insulation product designed specifically for below-ambient temperature applications in severe hot/humid operating environments.
  • Keeps insulation dry by using a specially designed wicking material that absorbs condensed water from the pipe surface and wicks it to the outside.
  • Ideal for dual temperature installations because it is rated for operating temperatures which range from 32°F to 220°F.
  • Meets model code fire requirements with a flame spread rating of 25 or less and a smoke development rating of 50 or less. This means the product will be granted immediate building code approval for use in air plenums and other critical locations.
  • Excellent thermal value which contributes to a lower operating costs at a favorable installed cost/performance ratio.
  • Can be installed directly over Wet Piping so systems don’t need to be shut down during the product’s installation.
  • Has a self-sealing Lap Seal with no need for staples or CP-11 Mastic.
  • Meets requirements for Mold and Fungi Resistance by providing no sustenance for mold to propagate.

Owens Corning VaporWick Pipe Insulation is a one of a kind insulation system ideal for chilled piping.

HORIZONTAL PIPING INSTALLATION INSTRUCTIONS:

The VaporWick Pipe Insulation system works by transporting moisture from the area around the pipe to the surface of the insulation. This is accomplished through the wick material but is aided by gravity. Therefore, horizontal runs must have the series of evaporating holes located in the down position. Please note this is 180 degrees different than current Fiberglass pipe covering installation practice.

Care must be taken during installation to ensure wick material stays in place while sliding, twisting, turning and/or alignment of insulation sections.

A sheet of loosely hanging polyethylene film on the pipe surface under the insulation may aid in installing insulation sections in and around confined locations and on wet and/or corroded pipe. When the insulation section is in place, hold the insulation and pull the polyethylene film out. The polyethylene film must be removed prior to final placement and closure of laps and joints.

Sections of pipe are tightly butted together and secured to each other as traditional Fiberglass pipe insulation using VaporWick Sealing Tape.

All VaporWick Pipe Insulation system terminations should be sealed with CP-11 mastic. Terminations include end of run transition to other material.

VERTICAL PIPING INSTALLATION INSTRUCTIONS:

Under severe conditions for any vertical piping insulation, moisture that enters the system will tend to accumulate at the bottom elbow. To ensure that vertical installations perform as designed, Owens Corning specifies the following:

Install VaporWick Pipe Insulation sections and seal the lap strip.  Tape all vertical evaporating holes using two overlapping strips of VaporWick Sealing Tape. Seal all butt ends as described in these instructions. The wick will still transport any moisture that does enter the system to the nearest evaporator section where it can be evaporated.

For vertical runs more than 9 feet long, a VaporWick Insulation skirt should be installed within 3 feet of the bottom elbow or termination.  Additional skirts should be installed every forty feet of vertical run. The bottom skirt should be within three feet of the bottom elbow or termination.

The skirt should be cut to length off a role of skirting material and installed between two sections of VaporWick Pipe Insulation.

The lower section of pipe insulation should be installed before installing the skirt. After the lower section of pipe is installed, wrap the skirt around the pipe and then slide it down into place until the line printed on the skirt is even with the outside edge of the pipe insulation. A piece of tape may be used to hold the skirt in place so that it doesn’t move when putting the rest of the insulation on. Illustrated in Figure 1.

After the skirt is in place and all the fingers of the skirt are setting in place, then install the section of VaporWick Pipe Insulation above the wick to sandwich the skirt between the two sections of pipe.

Lastly, wrap perforated tape around the exposed fingers sticking out from the skirt.

Illustrated in Figure 2. For all cases, vertical perforations should be taped over.
