Casement windows typically open outwards and so they provide excellent ventilation for homes. They are also an incredibly versatile style of window, complementing both modern and traditional properties.
Both uPVC and aluminium casement windows from Boston Trade Frames are high-performing options. Generally, uPVC is a more budget-friendly option and aluminium is better for larger windows because of the strength of the frames.
Of course – we offer a range of customisation options including colours, finishes and hardware. You can even choose decorative glass!
Casement windows are windows attached to their frame by one or more hinges on the side. Unlike sliding sash windows that move vertically, casement windows swing open outwards (or inwards in some cases).

In our Boston-based factory, we manufacture many of our casement windows using high-performance Kömmerling 70mm profiles, available in your choice of classic chamfered or contemporary ovolo detailing. This in-house manufacturing process allows us to ensure outstanding quality from the very start, with every window carefully crafted to deliver superior performance and durability.

From single sashes for smaller spaces to multiple sashes for larger openings, you can customise casement windows to suit your needs. These windows can be fixed or operable, allowing you to tailor the airflow and natural light to each room.
