Product Question + Answer

The Louvre fits on the internal wall and, similarly to the cowl, reduces draughts, noise and light penetration, while providing a free area of 100cm², it is only available in white. These are still significant savings when compared with MVHR systems, especially in homes where the heat recovery element would not be effective and ductwork would simply not be practical to install. Passive Ventilation The most controllable home ventilation systems are ‘active’ with fans to create either positive or negative pressure in the home. Often, carefully designed ductwork is used to balance the system across the building. The external cowl minimises uncomfortable draughts, reduces noise and light from outside the property and acts as a barrier against wind driven rain whilst providing a free area of 100cm² and is available in both brown and terracotta.
