Safe Ventilation
In tilt mode, the sash is fixed at 10-15° angle. Fresh air enters from above without creating drafts. Safe for children and pets.
Tilt-Turn Windows
The most popular and practical window type. One handle — two modes: full opening for glass cleaning and tilt mode for safe draft-free ventilation.
How the Tilt-Turn Mechanism Works
Universal solution for any room
A tilt-turn window opens in two modes thanks to special hardware. Turning the handle 90° opens the sash fully inward — convenient for cleaning glass and maximum ventilation. Turning 180° puts the window in tilt mode — the sash tilts inward at the top, providing draft-free ventilation.
Advantages of Tilt-Turn Windows
Why this is the most popular window type in Europe
Easy Glass Cleaning
Full inward opening allows easy cleaning of both sides of glass without leaning out the window. Especially important for upper floors.
Micro-Ventilation
Additional mode with minimal 5-7 mm gap. Constant fresh air flow even in winter without significant heat loss.

FAQ
Frequently Asked Questions About Tilt-Turn Windows
Why are tilt-turn windows so popular?
It's a universal solution: two opening modes in one window. Full opening for cleaning and maximum ventilation, tilt mode for comfortable draft-free ventilation. Suitable for any room.
Are these windows safe for children?
Yes, with child lock installed. It blocks turn mode, leaving only tilt — the child cannot fully open the window. This is a standard option for families with small children.
What is micro-ventilation?
Additional mode with minimal 5-7 mm gap. Handle turns 45° instead of 180°. Provides constant fresh air flow even in winter without significant heat loss.
What is the maximum sash size?
For tilt-turn sashes, width up to 1.3-1.4 m is recommended depending on profile and hardware. Height up to 1.8-2.0 m. Exact sizes are agreed upon during calculation.
Can a mosquito screen be installed?
Yes, the mosquito screen is installed outside and doesn't interfere with window opening in any mode. For tilt mode, special frame screens with magnets or on hinges are used.
How to care for the hardware?
Once a year, lubricate moving hardware parts with machine oil or special lubricant. Check fastening screw tightness. With proper care, hardware will last the entire window life.
Ready to spec your windows?
Use the 3D configurator to size up your windows and see a fair market price. Or compare the leading PVC and aluminium brands side by side.
