Locking System

True security is invisible – until it matters. Our German locking systems ensure maximum safety, airtightness, and peace of mind. Every window is designed to lock tight and stay tight.

What is a multi-point Lock?

When you close our window, multiple locking points engage automatically along the full edge. This ensures an even, tight pressure seal and unmatched security.
