Sidehung windows

Outward opening window, perfect for fire egress routes

Sidehung windows, also called casement windows, are a type of window that opens outwards on hinges attached to the side of the window frame. They are a popular choice for houses as they provide good ventilation and the best “clear opening” area for the size of the frame.

VELFAC composite windows bring together the best of both worlds; the durability and versatility of aluminium and the beauty and warmth of natural wood.




Description and benefits

Sidehung windows

Side hung windows are fairly versatile, so they’ll work in almost any window opening: they are ideal in spaces like living rooms or master bedrooms, and are also the best for fire egress routes. Another benefit of VELFAC side hung windows is their energy efficiency. When properly installed and sealed, they can help to keep a home comfortable and energy-efficient by preventing air leaks and minimizing heat transfer.  Despite their many benefits they may not be suitable for areas where space is limited, such as patios or decks.


Despite their many benefits, there are some drawbacks to consider when choosing casement windows. One potential issue is their size and weight, which can make them difficult to open and close, particularly for those with limited mobility. Additionally, because they open outward, they may not be suitable for areas where space is limited, such as patios or decks.


In conclusion, casement windows offer a range of benefits, including energy efficiency, easy maintenance, and versatile style options. However, homeowners should consider their specific needs and limitations when choosing windows for their home.
