Welcome

What is an Air barrier?

The Enershield air barrier creates a “virtual door” by re-circulating ambient air and directing it across an opening in a laminar airflow to create up to a 90% seal.  This “invisible” door seals the opening and provides an effective “environmental separation” and stops the transfer of temperature, humidity, dust, odours and insects.  With just a draught of air creating the barrier, vehicles and pedestrians can pass without obstruction.

Air Barrier v. Air Curtain

Air barriers should not be confused with a heated warm air curtain, whose primary design objective is to provide warmth at a retail doorway.  Without a proper seal over an open door, your expensively heated or air-conditioned air, along with the warm blast from a typical heated air curtain is immediately conveyed to the outside.

A typical 5kw air curtain operating 8 hours per day, 5 days per week will consume £1,000 of energy per annum.  In the same conditions, an Enershield air barrier will consume £60 of energy per annum.
