﻿Trickle ventilator has 5000 mm2 equivalent area
Greenwood Window Vents’ latest trickle ventilator has an equivalent area of 5000 mm2 — the minimum requirement for habitable rooms. The 5000EA trickle ventilator is just 410 mm long and enables fewer ventilators to be used to comply with Building Regulations. The innovative seal assists with compliance by improving air tightness — especially important in pressure testing for new buildings.
These trickle ventilators can be applied to the window profile over a standard 13 mm rout and have an upward-tilting deflector to avoid downward draughts.
