Onyx DW has been creating tailor-made traditional sash windows all over North London and the broader regions of London for several years, always using the highest of quality woods such as Meranti, Sapele and Oak.
We offer a variety of designs and ideas to support your needs in fitting with your home, all our wooden products can be highly customised, and we can provide a variety of glazing options- soundproofing, acoustic glass, draughtproofing to mention a few. We also offer many colour options – the traditional sash windows can be professionally colour sprayed chosen from our colour palette – decide to have a different shade to complement your interior décor internally.
Our sash windows have been designed to provide the replacement of original sash windows for listed buildings and builds that require this design type. However, these windows have all the traditional features, but with all the modern performance features of 21-century windows, offering both narrow, single and double-glazing.
At Onyx DW we pride ourselves on working with clients to devise a beneficial solution to a need, rather than embed an off the shelf product into an exclusive design requirement. Our knowledge allows us to cater to your specific design requirements, to develop it into a credible, well-suited and visually-compelling product.
Regardless of the size and intricacy of your development, we will ensure our timber windows provide a perfect fit, finish and specification and are delivered on budget within project timescales.

- Supply only;
