Suppliers of: Steel Windows, Steel Doors, Conservation Rooflights, glass doors, partitions, steel screens

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.

PRODUCTS

Steel Windows:

Clement steel windows are often specified as the preferred fenestration solution for buildings that are important, valuable or of high conservation value.  We work in partnership with architects, conservation officers, main contractors 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 aluminium. Steel also enables us to produce highly secure window systems which feature multi point locking and where appropriate we can offer windows that achieve the BS 7950 security standard.

Steel Doors:

Clement manufacture a beautiful selection of internal steel doors available in various styles and colours. They include multi point locking or a traditional mortice lock which can be matched to the windows in the building or used as a unique stand alone feature.

Conservation Rooflights:

Clement Conservation Rooflights are modern replicas of Victorian originals and so versatile they can be used in any type of property.  They are particularly suitable for Listed Buildings or heritage products and are regularly recommended by Architects and Conservation Officers.

We offer eight standard sizes with either a tile or slate profile to match the specific roof type ensuring a flush finish but our rooflights can also be tailored to bespoke requirements.

Glass Doors:

Clement Internal Glass Doors allow light to flood into a workspace area. Available a part of our internal product range or screens and partitions, our doors are widely specified in both commercial and domestic projects.

Steel Screens:

Internal metal and glass screens and doors will draw light into a partitioned space, flooding dark offices and boardrooms with natural daylight, while the acoustic features of the glass will mean that private meetings and discussions can still take place. 

Steel Partitions:

The current trend for the industrial aesthetic shows no sign of diminishing and an internal metal screen is the perfect architectural feature to create the feel of a room within a room, a space that is simultaneously private yet part of the wider area. The strong steel sections can be engineered to any design, while the slim sections that are only possible with steel mean that the maximum possible area of glass is provided, allowing maximum solar gain and creating the illusion of extra space.

Have you seen the new colour chart for Clement’s steel windows and doors?

July 2025

The team at Clement always talks about how many different colours are available for their bespoke steel windows and doors, but did you know you can now view these in the company’s new RAL Colour Chart?

Black steel doors and windows are still a popular look, but the colour options for standard polyester powder paint in a semi gloss or matt finish at Clement are numerous. There is also a huge range of non-standard colours, available at an extra cost.

Clement offers a dual colour finish too, where you can choose to paint the window frames different colours internally and externally. There are complementary silicone colours and specialist metallic effect finishes are also available – speak to a sales advisor for more information.

The company uses the fabulous powder paint colours by Akzo Nobel, who are renowned global leaders in advanced performance surface coatings. Akzo Nobel paints are highly durable and Clement’s factory specialists bake the paint on at a high temperature to give a superb finish.

Generally offered with a warranty of ten years, polyester powder coated steel windows and doors by Clement provide an average paint coating in excess of 100 microns, when the industry standard is 60 microns. Clement’s hot dip galvanised, polyester powder coated steel frames require minimal maintenance and last for many years.

Several customers have opted for unusual colour schemes – the team at Clement has manufactured blue windows, red door screens and yellow doors in recent years!

Clement B’ Rated super slim framed steel windows feature in magnificent new build

June 2025

Charters Property is a property developer specialising in premium quality residential development. They design and deliver exceptional homes throughout Shropshire and the wider area, and have over 25 years of experience working on historic buildings using traditional techniques.

Clement is proud that its products are often chosen by Charters for their amazing projects. This new build is the latest and showcases around thirty beautiful, bespoke steel windows and doors. The site is situated withing walking distance to Ludlow town with fabulous views of the river Corve and Ludlow Castle.

Outside, the external brickwork was covered in a breathable lime slurry. The new fenestration looks stunning against the white backdrop this created. Inside, the light flows in through the slim window and door sections opening up the already spacious rooms.

The Clement EB20 range of steel windows and W40 steel doors were chosen for their slim, strong frames and thermal efficiency.

The final result is incredible and we are delighted that our client is so pleased.

Charters said: “We have worked with Clement on numerous projects over the years, and they have consistently provided an excellent service. This project required a significant number of large steel windows, and they were able to deliver the scheme on time and to a very good standard. Their communication remained clear and client focused throughout the process and we would happily recommend their service.”
