Stop energy loss at the door

When doors are opened in heated buildings, colder external air flows in through the bottom part of the opening, while internal air flows out through the upper part.  In air conditioned buildings, the opposite applies. Over door air curtains deliver a uniform flow of air across the full door width that separates the interior and exterior atmospheres.

As well as their energy saving capacity, air curtains  have ‘hidden’ benefits. Over door air curtains induce warm air down from high level that would otherwise be lost through the roof, thus helping to de-stratify the building and eliminate cold spots. Among the air curtains new developments is a fresh design that promotes a laminar airflow and includes deep profile aerofoil section air straightening veins. These improve the efficiency of climate separation between the indoor and outdoor environment, compared to previous models.
