Doorway Behavior
The same nominal door width can behave very differently in a small storefront, a windy exterior entry, or a service entrance used by delivery carts. Mounting height, header depth, ceiling obstructions, and door-open time should be understood before equipment family selection.
Heated and unheated air curtains also need different electrical and control conversations. For heated use, voltage, control method, and available clearance should be checked early rather than added after a model has already been suggested.
