Smoke vent rooflights (AOVs) in Horsham: what is involved?
Smoke vent rooflights (AOVs) in Horsham means automatic smoke ventilators at the head of stairwells and atria. We cover the RH12 district and the rest of West Sussex, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. In Horsham, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.
We work across West Sussex, including Horsham, and in neighbouring towns such as Crawley and Horley. Access, parking and how the glass reaches the roof are all checked at the survey.

What to check first

- Replacing a vent with a non-equivalent product can affect the fire strategy
