Clement Windows has manufactured and installed metal windows and metal doors at a range of exciting refurbishment projects recently, a Central London office block, two hydroelectric power stations in Scotland and a Surrey Convent among them!

The former Uniform Works in London’s Clerkenwell Green was refurbished by Stagg Architects, extending the original 13,000 sq ft building by an additional 7,000 sq ft, with a new roof extension, flexible spaces on the ground and lower ground floors and offices at the upper levels.

Steel windows and doors from Clement’s EB20 range were selected because it was very important that the new fenestration perfectly complemented the industrial aesthetic of the refurbished building, helping to flood each floor with light.  As the building is surrounded by other properties on three sides the addition of so much natural light is a real bonus.  The huge wall of steel windows on one side of the building includes a patterned glass which allows light to enter the building while also providing privacy for the neighbouring properties.

Clement EB20 steel windows were created for projects where a traditional steel window appearance is required.  Designed to replicate the appearance of original or existing windows while simultaneously providing all the advantages of 21st century technology, EB20 windows are manufactured from recycled steel and all the windows in this range have exceptionally slim frames.  The use of krypton filled glass units means this product achieves a ‘B’ Window Energy Rating, thereby complying with the latest energy ratings for replacement windows.  The slimmer insulated glass unit used increases the ‘shadow line’ which enables the replica window to be close in appearance to the original putty glazed windows which some projects demand.

Ben Stagg, Director of Stagg Architects, remarked:

“Clement Windows was selected following a lot of research, and ultimately because they were able to offer the slimmest profile metal sections.  The appearance of the glazing is critical to the whole building design so we worked closely with Clement to achieve the desired appearance, with great success.”

The Lanark Hydro Electric Scheme refers to two hydroelectric plants, Bonnington and Stonebyres’ Power Stations, in Clydesdale, South Lanarkshire, Scotland.  The abundant supply of water from the River Clyde continuously spins the power stations’ turbines providing a reliable and sustainable source of renewable electricity.  Combined, they create enough electricity to power over 17,000 homes in the UK.

Recently refurbished by Drax Group, steel windows from the Clement W20 range with genuine T bars were chosen for the category ‘A’ Listed Buildings in order to provide as close a match to the original windows as possible.  A traditional, tried and tested robust window, designed in the 1960s but still in demand today, Clement W20 steel windows may be used in all types of building where strong, durable frames, efficient opening casements and hard wearing fittings are required.  Polyester powder painted in striking RAL 6005 Moss Green, Lodsworth handles complement the new windows with matching peg stays in Antique Bronze finish.

Clement made around 120 steel windows for the projects, including nearly 400 individual fixed lights, but the most beautiful is perhaps the enormous curved head windows on both sides of the buildings, which look spectacular and let in masses of natural light.  Commenting on the project, Drax Group Senior Civil Engineer, Anne Kerr, said:

“We are delighted with the service and quality of windows supplied and fitted by Clement.  The new steel windows fitted in the refurbished building look stunning and exceed our expectations.”

Ladywell Convent is the Motherhouse of the Franciscan Missionaries of the Divine Motherhood (FMDM) congregation, an international religious congregation of Catholic women.  Situated in the beautiful Surrey Hills, the Convent offers hospitality for returning Missionaries and visitors and is also the site of La Verna, a home for elderly sisters and those who support them.

An extensive refurbishment was recently carried out to the residential and conference buildings on the site ensuring their suitability for an aging group of sisters.  Two new support buildings were also constructed.

Side hung casements from the Clement Standard Metal Window (SMW) steel window range with genuine 12mm flat leads were installed in the new Greccio building, polyester powder painted RAL 9005 (Jet Black) semi gloss with the handles, hinges and peg stays powder coated to match the frames.

The Clement SMW window range is a stylish solution for a number of aesthetically sensitive historical projects.  SMW windows are used primarily for replacement work in Conservation Areas and Listed Buildings, where a suitable geometric match is required and double glazing is not an option.

Windows from the Clement EB20 steel window range with 12mm oval leads were installed in the Staff Building on the site, also painted RAL 9005.

Michael O’Brien from O&D Constuction said:

“Steel windows manufactured by Clement were the right choice because of their close match to the existing heritage windows at Ladywell Convent.  The team at Clement did a great job – they delivered the project on time and there were no issues.”

As these projects show, steel is one of the most versatile materials available for window frames and can be moulded into virtually any shape – when it comes to new steel windows, the only limit is your own imagination!

Clement Windows Group manufactures and installs an innovative range of steel windows, doors and screens, specialising in conservation work for both private residences and commercial projects.  The company also offers a range of conservation rooflights, available from stock or made bespoke to individual requirements, in either a tile or a slate profile.
