Frequently Asked Questions

Do air curtains keep cold air in?

Yes. Air curtains and strip curtain barriers create a physical or airflow seal across the door opening, significantly reducing the exchange of cold interior air with warmer outside air. This helps maintain consistent internal temperatures, lowers compressor workload, and reduces energy costs in walk-in coolers and freezers.
