Heated vs unheated project conditions
Carry the doorway facts into the specification reference, worksheet, product family, and current model-document request.
| Project condition | Heated path | Unheated path | Information to confirm |
| Winter comfort at a public entrance | Review when staff or customers experience a cold draft | Review when separation is the main goal and added heat is not required | Opening, mounting height, exposure, voltage, circuit capacity, controls |
| Cold-room or temperature-separated doorway | May be part of the review when the ambient side needs comfort | May fit when the main need is a doorway air barrier | Temperature split, cycles, moisture, frost notes, service access |
| Dust or insect entry | Heat is optional and should not be assumed to solve the source condition | Often the first separation path to compare | Traffic, exposure, door operation, cleaning access, mounting |
| Replacement project | Requires electrical and control compatibility review | May simplify the electrical path | Existing model, wiring, voltage, controls, dimensions, current documents |
Add these details to the model request
| Field | What to include |
| Doorway | Finished width, clear height, mounting height, traffic, exposure, photos |
| Comfort | Winter complaint, temperature separation, wind, dust, insects, or service-door duty |
| Electrical | Voltage, phase, frequency, circuit capacity, control location, interlock |
| Documents | Dimensions, heating type, power, sound, controls, installation, certification, warranty |
