Division 22 23 Ebook Page 177 VaporWick Pipe Insulation Drafted for Service at Fort Campbell Case Study

Features and Benefits pipe insulation is designed specifically for severe hot and 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 degrees F to 220 degrees 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 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 mastic. Provides no sustenance for mold to propagate and meets the standard ASTM test for fungi resistance. "I've done a couple of installations myself - hands on - at a local hospital," explains Embry. "The project was on a system that was in service and the pipe was wet. They couldn't shut down because it is a hospital. The VaporWick insulation worked out great. "The hospital was really impressed," he continues. "We had a meeting with Infectious Control, the Maintenance supervisors and Housekeeping, and we showed them the product. Once they saw the tapes that Owens Corning made showing how the product is made and how it works, they understood the theory behind the product. They could see why the wicking material is there and what it's going to do. It made complete sense to them. "They really liked the fact that they didn't have to worry about any shut down and when we put the product on wet pipe it showed them immediately that the product will stop the problems associated with condensation. We haven't had any call backs at all on it and we like that." Embry says the hospital replaced the old insulation because the pipes were dripping and also supporting mold growth. "We killed two birds with one stone," he says. "We stopped the condensation and got rid of the mold. The hospital also liked the appearance of it. VaporWick pipe insulation looked better than the original product did, even when it the original product was new. It's just a neater looking product. "We're satisfied with using it," continues Embry. "We just had to get used to the little bit of difference in the installation between what I now call the 'old fashioned' product with the ASJ jacketing, and the VaporWick insulation. Once you and your men learn how to handle it, cut fittings and things like that, production picks up. For new installations with straight runs, it actually goes on a little faster than standard pipe insulation, especially on copper pipe." What's the most important benefit of VaporWick insulation? Embry thinks it will eventually be 'customer satisfaction.' But he says customers need to understand the value before they will spend the additional money for the product. "Right now, we're on the borderline of trying to meet our production goals because it is a little bit slower," explains Embry. "Work is slow right now so our competitors are bidding cheaper than they would with a normal workload, so that has made it hard to get a job using VaporWick pipe insulation. People are really cost conscious. "But if they look at the longevity of it, they will see where they can save some money," he continues. "But I just feel the customer is going to be happier with the ( VaporWick pipe insulation) product. Customers seem to appreciate more the jobs we're doing with this new product." Embry says he expects the twin problems of moisture and mold to continue driving the use of VaporWick pipe insulation. Product Information VaporWick insulation is for piping systems that operate below ambient temperatures, which present special considerations due to the possibility of water vapor migration to the cold pipe surface. insulation incorporates a patented concept that uses a wicking material to remove condensed water from the system, keeping the insulation dry. When the ambient conditions are such that the vapor drive is toward the cold pipe, any water vapor that enters the system and condenses on the cold pipe surface is removed to the outer surface by capillary action, where it then evaporates to the ambient air. "Mold is a big issue now, especially in hospitals and schools," he says. "The schools around this area in the bigger communities, such as Louisville, are going to VaporWick insulation because a lot of their existing piping is in crawl space areas with a lot of moisture and humidity. " VaporWick insulation won't stop the humidity coming from a leaking drain or something like that, but it won't promote any more condensation in the trenches and it won't promote mold growth. Overall, we really like the product." We had a lot of skeptical people in the beginning but in the end everybody seems to like the product. We've got customers who are using it now by their own choice, not just because it is specified for a project." David Carver, Breeding Insulation, Nashville VaporWick
