Project conditions
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 review.
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.
Equipment fit
Air Curtain Fit
Most retail entrance conversations begin with commercial air curtains. Unit heater support may appear when the project is really about entry comfort in colder conditions, but the air curtain remains the doorway equipment choice.
Airflow, sound, controls, electrical data, and any certification language should stay tied to the exact model before they move into quotation or submittal language.
Project data
Start with air curtains; add heating review only when the doorway comfort requirement and power conditions are clear.
- Finished width, clear height, and mounting height
- Traffic pattern and exterior exposure
- Heated or unheated preference
- Voltage, door switch, and control expectation
