Our windows with a bottom-hinged frame are supplied standard with an additional device that allows the window to be opened a few millimetres at the top.
This ensures correct ventilation of the home without excess heat loss and prevents the formation of  condensate and mould.

To give a more stylish frame, while maintaining standard performance, our bottom-hinged frames (>78 mm thickness) can be supplied with concealed hardware, which is completely invisible when the window is closed.

All our French windows come with a thermal-cut sill, which offers the following advantages:

• reduced heat loss
• reduced condensation, the cause of mould formation
• reduced noise transmission

All our frames come with three weather-strips for thermal and acoustic insulation, a guarantee of excellent performance over time.
