Installation Instructions VaporWick Pipe Insulation General VaporWick Pipe Insulation System Requirements A. VaporWick Pipe Insulation consists of: Owens Corning Fiberglas pipe insulation An inner wick material that is factory installed on the inner surface A resilient, tough, soil- resistant polymer facing Factory-applied adhesive mechanical closure for longitudinal jacket seams B. VaporWick Pipe Insulation is an innovative insulation product designed specifically for below ambient temperature applications in severe hot/humid operating environments. The heart of the system is a wick material that transports condensed water to the outside of the system for evaporation to the atmosphere. The wick keeps the Fiberglas insulation dry, preventing dripping and allowing the insulation to perform effectively over the life of the project. C. The VaporWick Pipe Insulation system can be applied on new and replacement jobs. Unlike traditional insulation, this system may readily be installed on operating systems even if the pipes are wet and slightly corroded. Caution is needed on severely corroded sections as pipe diameters may exceed those listed in ASTM C585. This may cause an improper pipe fit and result in overloading of the system and/or failure of the closure tape resulting in system failure. For severely corroded pipes, rust and scale should be removed before installation. D. Sufficient insulation thickness must be selected to minimize condensation on the outer surface. Please refer to the VaporWick Pipe Insulation Submittal Sheet for recommended thickness to prevent surface condensation. E. The VaporWick Pipe Insulation system is not recommended for outdoor, washdown or exposed piping where painting is required, or where additional jacket finish is required. Stickers, labels or colored tape are recommended for pipe service identification. Application Requirements A. VaporWick Pipe Insulation is designed for installation on cold piping and dual temperature piping operating at temperatures from 32F (0C) to 220F (104C) in buildings and industrial facilities. B. Installation of VaporWick Pipe Insulation is similar to regular Fiberglas pipe insulation. There are a few important differences and some common installation practices that must be followed. C. VaporWick Pipe Insulation can be cut with a sharp knife. Scissors are handy for cutting the wick material, facing and sealing tape. Short pieces of insulation can be cut without jacket loss; it won't come apart in handling. D. Straight sections of VaporWick Pipe Insulation have factory- installed wick material. Hinged sections of VaporWick Pipe Insulation are opened, placed over the pipe, carefully aligned and sealed. E. Wick material must make a continuous connection (path) through all pipe, flanges, fittings, valves and hangers. Flanges, fittings, valves and hangers must have field- applied VaporWick Wick Material wrapped in place to make the wick system continuous throughout the insulated system. Horizontal and Vertical Runs A. 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 Fiberglas pipe covering installation practice. B. Care must be taken during installation to ensure wick material stays in place while sliding, twisting, turning and/or alignment of insulation sections. C.
