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.
