- How far should a Roof AOV open?
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?
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.
- What is BS EN12101-2?
BS EN12101-2 is a European standard that specifies the requirements and test methods for natural smoke and heat exhaust ventilators (NSHEVs). The standard covers the design, performance, installation, and maintenance of NSHEVs.
