Gaulhofer is your number one choice in North America for European Tilt and Turn Windows. The inward swinging window is operated with only one handle for an easy-to-use 3-position operation: locking, opening, and tilting. In the closed position, several locking points ensure safety as well as an airtight fit of the triple weather strip system, keeping unwanted insect guests – and the weather – outside where they belong. For daytime ventilation, the window can be tilted. In this position, it allows gentle air movement but still provides security against intruders. In the turn position (inward opening) you can gain large amounts of ventilation quickly. It is now also easy to clean the exterior surface of the glass.
