Thurston & Sons, Inc. 3335 Croft Street Norfolk, VA 23513 757-855-7700 800-444-7713 www.cethurston.com 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. VaporWick insulation incorporates a patented concept that uses a wicking material to remove condensed water from the system, keeping the insulation dry. 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. Exceptional Pipe Insulation Passes Four Exams There aren't many three year olds who can pass university- level exams but VaporWick pipe insulation has done it four times. After nearly three years of service in a hot and humid environment at Old Dominion University, Norfolk, Virginia, VaporWick pipe insulation was checked at the site and found dry to the touch. There were no telltale stains on the insulation or the floor that would indicate dripping since product was installed. Samples were then removed and taken to a laboratory for microscopic examination by a veteran university professor of microbiology. After checking the samples with a 40-400x binocular microscope using fiber optic illumination for improved visibility, the professor declared the samples free of visual mold growth. "The VaporWick pipe insulation installed at Old Dominion University is free of fungal contamination at this time. No characteristic patterns of fungal growth, that is, mycelia, or reproductive fungal structures were observed." The professor also then tested fresh samples of VaporWick insulation to see if mold growth would take place. For this test he placed samples in an environmental chamber for three months with 90 percent relative humidity and a temperature of 90 F. The result: Still no mold. "Even under conditions normally conducive to mold growth, none of the pipe insulation samples supported growth of fungi," wrote the professor after concluding his tests. In a final exam, the professor subjected all the individual components of VaporWick pipe insulation to the 28-day ASTM C1338 Mold Resistance Test. Once again, VaporWick insulation passed with high marks. "Even with the addition of inorganic or organic nutrients, mold growth in excess of that occurring on the standard tongue depressor does not occur on any of the components. This study verifies that all components of VaporWick will not support the growth of mold even in the presence of added nutrient."
