Window ventilation · Window ventilation07 · Window ventilation and trickle vents Window ventilation: fresh air, designed around the window
Window ventilation provides a controlled supply of fresh air at window level. Profile, glazing, acoustic requirements and the exposure of the façade determine the right vent — which is why we choose it together with the window, before production.
The vent chosen together with the window
The vent is chosen and fitted before the window is manufactured.
