Recently the state of Connecticut’s Facilities Administrator made public their choice to install an air curtain at the west entrance to the capitol in preparation to keep the security staff warm next winter. An air curtain is ideal in environments where large volumes of visitors cause doors to open repeatedly or stay open as crowds swell to enter and exit. It’s the best and sometimes only protective invisible barrier for damaging cold incursions that would otherwise tax building climate control systems that struggle to keep up with such pressures. Put the Mars air curtain to work for you and put change in the air.
