To really effectively cool a room, you need to let cool, fresh air in and also let warm, stale air out. This can be tricky if a room only has a single outside wall. Zenera Louvre Windows are an ideal solution for internal wall applications as they offer maximum ventilation for their size and fit almost any space available. By using  aluminium or obscure glass louvres means rooms can remain private.

These are perfect for washrooms and toilets as they allow ventilation and privacy simultaneously.
