Cothern says the crew at Memphis City Schools told him they like VaporWick insulation because they don't need to do as much time- consuming work to seal the system, compared to the expanded polystyrene foam insulation they considered. "They are pretty much thrilled with the result," says Cothern. "Their moisture problems are going away." George says they did have a scare that shook the crew's confidence in VaporWick insulation. On a particularly warm day this spring they found condensation forming on the surface of insulation they had recently installed. They called for help and within 24 hours an Owens Corning technical representative was on the scene. After a thorough check of the building, the Owens Corning representative found a duct on the roof of the school that was allowing unconditioned outside air to enter the space above the ceiling tile. "The duct was supposed to exhaust air to the atmosphere, not let unconditioned air into the building," says George. "The air handling system inside the building was supposed to be over-pressured so air would exit the building. Instead, there was negative pressure and air was being sucked inside. Once we fixed that, the condensation problem went away." The only remaining problem for the maintenance crew is responding to all the requests their success has generated. To attack that problem, Campbell returned to Memphis in September to train a second crew on the installation of VaporWick insulation. The new pipe insulation crew includes Phillip Dortch, Darrell Edwards, Stinson Dandridge and Quentin Hopson. With doubters becoming believers, air pressures being reversed and more crews learning how to install VaporWick insulation, it appears there is a lot of learning taking place at Memphis City Schools.

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 lower operating costs and 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. Resists mold and fungus growth.
