Dunham-Bush - Door Curtains

Door Curtains - Sentinel Door Curtains - Sentry Door Curtains - Entry Door Curtains - Entrance Heating - Electric Heating

A heated air-stream above an open doorway provides a virtual barrier, separating indoor and outdoor environments. This helps to reduce heat loss and energy consumption, and increase internal comfort air without effecting pedestrian traffic.

Dunham-Bush's door curtains offer a wide range of options making them suitable for most applications, particularly ideal for commercial and retail premises where entrance problems are an issue due to doorways being permanently open for high levels of pedestrian traffic.

Sentry Door Curtains

Sentry door curtains are available four models - each model with the left or right handed coil connections and top or back pipe entry into the casing:

  1. Cased horizontal unit (CH)
  2. Cased vertical unit (CV)
  3. Basic chassis horizontal unit (BH)
  4. Basic chassis vertical unit (BV)

Each model is available in three basic sizes (figure number).

  • Fig 10 - 1000mm (1000mm doorway or less)
  • Fig 15 - 1500mm (1000mm - 1500mm doorway)
  • Fig 20 - 2000mm (1500mm - 2000mm doorway)

Sentinel Door Curtains

Sentinel door curtains are available in a range of models, for ambient, LPHW and electric heating. Each model is available in three sizes complete with motor, tangential fan(s), optional LPHW coil or black bar electric heating elements and electrical connection box. All models are finished with a durable white polyester powder paint satin coating (RAL9010 30% gloss).

Sentinel door curtains are supplied with a remote switching control box and wall mounting bracket.


  • On/off switch
