We know that the right windows and doors make a striking difference to a property and the Clement team work hard to create a unique and stunning look for every client.

New or replacement steel windows will enhance your home in a number of ways, resulting in lower energy bills, greater security and a reduction in noise. At Clement, we are experts in replicating original windows and we offer a wide range of steel frames so you can be sure there is one to match the look of your windows. Our steel window frames require minimal maintenance and add a level of quality and comfort that older windows simply do not provide.

We offer a range of stunning steel doors and screens for residential properties as well as a choice of conservation rooflights, which are regularly specified by Architects and Conservation Officers because of their handsome appearance when compared to modern equivalents.

You can view our case studies here and take a look at photos of previous residential window projects here.

If your property is in need of the Clement touch, please contact us for a free, no obligation quotation. You can also visit our showroom to view our latest steel window products.


Clement Steel Windows


New or replacement steel windows are not only visually stunning with their slim and elegant sightlines, they also result in lower energy bills, greater security and a reduction in noise. Clement offers a broad range of windows to suit every purpose. We specialise in the replication of existing windows while respecting and enhancing important heritage and conservation objectives.

Clement Windows Steel Doors & Screens


Clement's steel doors and screens are made from slim steel sections. Offered with multi point locking or a traditional mortice lock, they come in a range of colours to match your interior design or to create a unique look. Safety glass is standard and a number of glazing options are offered for fireproofing, security and to meet solar and acoustic requirements.

Clement Windows Conservation Rooflights


The Clement Conservation Rooflight is a modern reproduction of a Victorian original, manufactured for a range of heritage projects. Available in eight standard sizes for a tile or a slate profile, when your rooflight is installed it will lie flush with the roof line. If one of our standard sizes does not fit, we also manufacture bespoke sizes.
