Enershield Microshield Air Barrier

Save up to 15 Units of Energy for Every One Unit of Energy Consumed by the Air Barrier!

With the cost of energy continuing to rise, heating / cooling bills for your building are a major expense. For businesses that keep their doors open for passing foot traffic, these costs are even greater. Properly selecting a custom made Enershield Air Barrier that can create an efficient and effective seal is as important as the decision to install the technology. We design and custom build our units to perform in the toughest climates, hot or cold. We don’t take any shortcuts when it comes to quality. There are varying Air Barrier concepts on the market claiming to be equal to the Enershield design, but when comparing feature to feature they fall well short.

The Enershield Microshield Air Barrier is CSA Listed in Canada and UL Listed in US and Canada.

Air Barriers shouldn’t be confused with a heated warm air curtain, whose primary objective is to provide warmth at open doorways. Without a proper seal, your expensively heated / air-conditioned air, along with the warm blast from a typical heated air curtain is immediately conveyed to the outside. A typical 8kw air curtain, operating 8 hrs per day, 5 days a week will consume in excess of $1200 of electricity over 6 months. Under the same conditions an Enershield unit will consume $80 of electricity for the entire year! Enershield Air Barriers create an effective seal on the doorway by re-circulating the facility air in a laminar (smooth) flow across an open doorway. The kinetic energy in the moving air generates a barrier, like a waterfall, that prevents leakage of air between two areas with different pressure and climate. The more laminar this air flow, the harder it is for outside air to penetrate the barrier.
