Steel windows are often specified as the preferred commercial fenestration solution for buildings that are important, valuable or of high conservation value and have listed status. Our approach is to work in partnership with main contractors and other building professionals to help produce specifications and complete installations that are visually stunning and offer improved performance, while respecting and enhancing important heritage and conservation objectives.
Clement is a gold member of Constructionline, the UK’s leading procurement and supply chain management service and also holds accreditations with CHAS (The Contractors Health & Safety Assessment Scheme), the CQMS Safety Scheme and Acclaim.

CASE STUDIES
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'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.
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.
