Unisert Adjustable Glass Louvres
Exterior burglar proofing severely limits the operation of traditional side- or top hung windows. If you opt for sliding or sash hung windows, less than 50% of the window can admit air.
The well-known “Unisert” adjustable glass louvre has been one of the flagship products even before the start of Aluvent Shutters. Sales dramatically increased, as summer and a need for ventilation became prevalent. This product is also used within Africa, even chosen above cheaper products from the Far East.
Consider louvres. Their unique system requires a gap of only 10cm between it and the burglar proofing to work at their maximum opening, allowing free ventilation of 86% of the window size and the airflow is directional.
Obviously, with so many moving parts, top quality is essential for long life.
