Steel windows are often specified as the preferred fenestration solution for architecture that is important, valuable or of high conservation value.

Clement’s approach is to work in partnership with architects and other building professionals to help produce specifications that are visually stunning and offer high technical performance, while respecting and enhancing important heritage and conservation objectives.

Arrangements for Listed Buildings or those in Conservation Areas can replicate existing steel fenestration, while improving thermal performance and security. Specifications for new build projects make the most of steel’s strength to produce slender frames with elegant sight lines which are incomparable to other supposedly similar materials such as aluminum. Steel also enables us to produce highly secure window systems which feature multi point locking and where appropriate we can offer architectural windows that achieve the BS 7950 security standard.

Find out more about our architectural steel windows, doors and screens and conservation rooflights. You can view our case studies here and take a look at our photo gallery here. If you are interested in our RIBA Approved CPD Seminar, there is more information here.

If you are looking for technical advice and support for your fenestration project, please contact us for more information.


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 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.
