Clement Windows Group

Clement Windows Group Clement offers an innovative range of steel windows, doors, screens and conservation rooflights.

Clement manufactures an innovative range of steel windows, steel doors and steel screens for both private residences and commercial projects. We provide a complete service – from the provision of technical drawings through to manufacture, installation and after sales support - whether your project is a traditional restoration project, one involving Listed Buildings or Conservation Areas, or a new

build. Our previous work includes prestigious heritage projects across the UK and in the USA, including well known buildings such as Bonhams in London, Norwich City Hall and the Eldorado Building in Manhattan. We take pride in our reputation for premium products, excellent craftsmanship and industry expertise and we are delighted that so many of our customers return to us time and again because they know they cannot get a better window anywhere else. We specialise in manufacturing new steel windows which look similar to original or existing heritage metal windows. Our hot rolled steel windows and doors are produced from 98% recycled steel source material and meet the latest performance requirements for insulation, weatherproofing and security. We also manufacture cold formed, thermally broken steel profile systems by Jansen. All of our windows are crafted to your bespoke design in our ISO 9001 and ISO 14001 approved factory. With Clement Windows you can expect technologically advanced, yet low maintenance steel windows, which will last for many years. Clement also supplies a selection of conservation rooflights, available from stock in either a tile or a slate profile. If a standard size does not meet your requirements, bespoke options are also available.

All Clement premium steel windows and doors are made to your exact requirements.

One of our most popular options is choosing a different colour for the inside of your frames than the outside. This means your new steel windows can complement the exterior of your property while perfectly matching your interior style.

This stunning high-end apartment development in The Harley Street Conservation Area required black steel windows externally, but the homeowners were able to personalise the interior frame colour to suit their own taste.

Thinking about a steel window or door project? We'd love to help. Call us on 01428 643393 to discuss your ideas.
