Casement windows in Ipswich and Oxford to Essex and Suffolk
The most popular window style, casement windows are the standard windows you will find on homes around Britain. Casement windows can be opened wider than any other type, allowing for maximum ventilation. They also require the fewest muntins, which are panel-dividing strips, so provide the best views and let the natural light in.
Available in high-performance uPVC, timber and aluminium, they are the most versatile window style as they can fit perfectly into any home regardless of its style and age thanks to their plethora of colour and customisation options. Whether you are replacing a different style or simply want to improve your home’s performance with double or triple glazed windows, we can create a window that matches your vision in the design and buying journey.
What is a casement window?
Casement windows are attached to the frame by one or more hinges on either the left or right side, so whether it’s open or closed it is permanently bolted into the space, unlike the vertical sash design. As casement windows have no meeting rail, they offer a versatile number of outwards opening mechanisms, including horizontally or vertically. This makes them an ideal replacement window solution that can fit any niche shape or space.
