Working conditions make a significant difference.

Starting with a framed opening, with barrier in place, competent installers tell us they can install a JanAire PolyVent in half the time that would be needed to install a conventional curtain. It is hard to be more specific due to all the variables involved.


Two people working at ground level have installed a 3′ x 168′ unit, from start to finish in three hours. The next day, those same two people working with stepladders, installed a 4′ x 120′ unit in four hours.
