Lemon Glass casement windows are designed to complement all type of projects, including window replacement, refurbishments and new builds.
We offer two casement windows design options – flush fit and storm-proof – and both are designed and manufactured to deliver the highest thermal, acoustic, weather and security performance.
Casement windows are typically top-hung or side-hung and can be rectangular, arched or circular, so we can customise them to provide a perfect fit. We can also provide mock sash casement windows, finished with ‘horns’ to provide an authentic sash window look.
Whether you live in a Victorian terrace or a country cottage, in a listed property or in a contemporary new-build, we will be able to provide a casement window suitable for the property.

Our environmentally-friendly approach to manufacturing ensures that our products are produced to the highest energy rating standards that contribute to a cleaner, more sustainable world.
By switching to energy efficient windows you can save energy and reduce your household bills, and all our products are available in 1.1 – 1.5 w/m2k U-value, A-rated units.
All our products are internally glazed for advanced security and we offer multi-point locking mechanisms as standard for all our casement windows.
Our concealed hinges (including the restricted option) allow the sash, when opened, to slide towards the centre of the frame, and thus enable the outside to be accessed for easy cleaning.
