Use German Doric multi-point locks, hinges and handles. The handle is top-notch anti-theft with a long solid aluminum backplate. The cylinders are practically inaccessible, and the long backplate is nearly impossible to remove. Features high quality components, each capable of holding up to 400 lbs, for high safety and long life. Friction stays are tested for over 400,000 cycles, and in the long run, a window that is opened and closed 10 times a day should last at least 100 years before failing.
Besides Ensuringthe Stability of The Window ,ltCanEven Work Lastingly MoreThan400000Times
Made of high-quality materials, it has strong load-bearing capacity and wind resistance, and can remain stable and solid after a long time of use.

Q: Why do old windows even need to be replaced?
Condensation: Energy-efficient windows have a warmer interior surface, so they can increase humidity without getting damp on the windows that could eventually damage the walls. Reducing condensation also helps reduce mold growth.
Air Quality: Tight-fitting windows keep out dust, bugs, pollen and sound—so the indoor environment is healthier.
Q: Condensation was a nuisance on my old windows, but I've heard it can cause damage too. really?
