What do smoke vent rooflights (AOVs) in Lerwick involve?
Smoke vent rooflights (AOVs) in Lerwick: by arrangement. In short, automatic smoke ventilators at the head of stairwells and atria. We confirm travel and timing before any survey is booked, then fix the price in writing.
Many Scottish homes have dormers and attic rooms where an extra roof window adds light without a full dormer. In Lerwick, as anywhere, smoke vent rooflights (AOVs) are the usual choice for blocks of flats and commercial buildings with a smoke strategy.
We cover Lerwick by arrangement: travel, ferries and weather affect what is practical, so we confirm what we can offer before quoting.

Rules and responsibilities in Lerwick
Smoke vents are life-safety equipment: in Scotland the duty holder must keep them maintained under the Fire (Scotland) Act 2005 and the Fire Safety (Scotland) Regulations 2006. We install to the building's fire strategy and the manufacturer's certification.
For non-domestic buildings in Scotland, the non-domestic Technical Handbook (section 6) sets the energy standards for rooflights; we supply the manufacturer's data for the building warrant. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Do you design the smoke strategy?
No — the strategy comes from the building's fire engineer or designer. We supply, install, commission and service to it.
Do smoke vents need a control panel?
Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.

Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
