Frequently Asked Questions

Why choose an AOV Louvre instead of a window?2023-10-17T12:48:27+01:00

Aside from the obvious appearance reasons there are a few other benefits louvres can provide when used in smoke ventilation.

  • Glazed AOV louvres provide more flexbility in structural opening dimensions, making full, floor to ceiling height window possible.
  • It’s not always possible to install a Julliet Balcony of  other fall arrest structure on facades, so louvres can work better in these situations.  During design, the individual blades can be customised to be fixed instead of opening with the rest of the vent.
  • Thermal efficiency, louvres can have better U-Value ratings than casement windows.
What safety measures are required for fall arrest in smoke shafts?2023-06-02T16:22:41+01:00

Smoke shafts typically extend the height of multiple floors in a building and the size of the vent openings introduces a safety issue. It’s important to ensure that grills and fall arresters are installed as required to prevent accidental falls.

What are the common sizes for Dampers and Smoke Shafts?2023-06-02T16:22:18+01:00

There’s no standard size but the most common sizes are below.

Dampers – 800w x 1920h
Doors – 1000w x 1500h
Shaft – 850×1800 or 1000m x 1500m throat size

How far should a Roof AOV open?2023-06-02T16:18:44+01:00

For single vents the vent will need to have an opening angle of at least 140°. Twin vents that are installed side by side should have each leaf open to at least 90°. This is primarily to reduce damage caused by wind and to ensure adequate airflow.

Can I use an AOV rooflight as an access hatch?2023-06-08T12:01:31+01:00

Yes, we’re able to supply the roof hatch with an offset motor assembly. This will allow you to place a ladder alongside and gain access to the roof when the hatch is open.
