The process of manufacturing wallcovering uses air for heating and water for cooling. At Len-Tex, our cooling water is in a sealed refrigeration system, allowing us to use the same water over and over again in our process without water loss through evaporation. Our heated air is recirculated at the rate of 75% throughout our process. This not only saves energy, it also reduces our emissions dramatically – so dramatically that the State of New Hampshire no longer requires air quality permits for Len-Tex emissions.
