Case Study: Kohler
A roof system for all seasons
The Kohler Company – popular manufacturer of kitchen and bath fixtures had been dealing with significant roof condensation issues at their Distribution Center, in Manitowoc, WI. The problem mainly stemmed from a metal roof.
The facility has a 945,000 square feet metal roof. The movement of the metal panels due to thermal contraction and expansion over time caused the closure of seals at the expansion joints to be pushed out. This allowed heated air to migrate to the roof surface causing the metal roof condensation problems. In a climate like Wisconsin, where temperatures vary widely throughout the year, this was a recurring problem that was only getting worse. So they contacted one of the leading roofing companies in the region for help.
Crafts, Inc. located in Manitowoc, WI is known for innovation when it comes to roofing. Mike Shultz, VP of Operations for Crafts assessed the problem at the Kohler Distribution Center and came up with the solution for the metal roof condensation issues.
Crafts’ solution was to fill the flutes with ISO board, a cover board, and install a PVC membrane over the roof. This would reduce the thermal expansion and contraction. However, Crafts’ went a step further and contacted Chuck Johnson with V2T Roof System with their idea of using the V2T vents to facilitate the removal of any residual moisture generated from operations in the building to help eliminate condensation. This would increase the performance of the roof, despite changing thermal conditions, and also effectively remove further causes of condensation and roof leaks. Craft proposed the installation of the innovative idea to Kohler’s engineers to address their roofing needs.
V2T Technology is working with contractors across the country to utilize the benefits of our patented vent system. V2T engineers each roof for cost effective installations, uplift resistance, moisture reduction and superior performance over conventional roofing.
