Window and door hardware – everything you need to know
10. 2. 2026.

When choosing PVC windows and doors, most people focus on the profile, number of chambers or type of glass. However, one of the most important parts of any PVC joinery often goes unnoticed — the hardware.
It is precisely the hardware that enables proper opening and closing of windows, secure locking, good sealing and long-lasting operation without problems.

What is hardware?
Hardware consists of the mechanical parts that enable the functionality of windows and doors: opening, closing, ventilation and locking. PVC window and door hardware is a mechanical system that connects the sash and frame, enabling tilt ventilation, micro-ventilation, multi-point locking and home security.
The most common types are tilt-and-turn, anti-burglary security and concealed hardware.
Why is it important?
Quality hardware ensures better insulation, security, durability and ease of use. That is why in the production of our windows and doors we use only proven hardware from leading European manufacturers such as Maco, Winkhaus and Siegenia.

Possible hardware problems and how to maintain it properly
The most common problems are a sagging sash, poor sealing and a sticking handle — issues our fitters and service technicians can resolve quickly and easily, but also prevent through proper installation and quality control before the products leave our production facility.
How to maintain it?
In most cases hardware requires very little care — lubrication and cleaning 1–2 times a year are recommended so it doesn't stick or get damaged during use.
Conclusion
Hardware is essential for the security, insulation and durability of PVC joinery, which is why it's important to choose hardware that will work for many years as if it were brand new — and that is exactly the kind of hardware you'll find on every piece of our joinery.
