Aluminium Casement Windows
Our London customers can also choose to have their casement windows in an aluminium profile. This sleek and minimalistic window design is the perfect choice if you are looking for something more contemporary. We offer a range of colours, finishes and hardware accessories to complete the final look.
Aluminium is one of the strongest materials on the market, making it often the superior choice for homeowners in London. The incredible strength of this material will help to keep your home structurally intact and can hold excellent resistance against unwelcome draughts and water ingress due to adverse weather.
Our Colour Options
Our sliding sash windows are available in a wide range of colours, including stunning, authentic woodgrains. Whatever age of property these windows are to be installed in we have a colour to suit. We even offer a bespoke colour bonding service, whereby we can produce windows in almost any conceivable hue.
The Legacy PVCu sliding sash windows we supply are equipped with a whole range of different hardware. The hardware we use has been carefully selected based on aesthetics, robustness, and ease of use. Our heritage hardware maintains the authentic period charm that makes these windows a great timber replica. Options also include travel restrictors.

Can I replace existing timber windows in a conservation area with PVCu sash windows?

We can advise on enquiry as to the customisation options that would provide the greatest chance of approval. Our team are here to help!
Can I install your sash windows in new builds?
Yes, you can install our products into a new build home. Our windows and doors are tested to comply with new build regulations, including Approved Document Q (security).
It’s important to let us know if you’re ordering products for a new build, as the specification will need to be altered to ensure the products are compliant.
