Cladding & External Finishes Feature
thickness of the oxide layer determines the colour lightness or darkness. Then, pre-patination enables designers to determine both the colour and intensity of blue/green patina for each project with ‘living’ surfaces. Here, as well as a solid patina colour, other intensities can be created revealing some of the dark oxidised background material.
COPPER ALLOYS Of course, copper alloys have also been used throughout history and bronze and brass – which can also be pre-weathered – remain popular for architectural applications. In addition, a recently developed alloy of copper with aluminium and zinc gives a rich golden through-colour. Its surface retains the golden through-colour and simply loses some of its sheen, as the oxide layer thickens with exposure to the atmosphere to give a protective matt finish. This golden alloy behaves differently to other copper products over time and does not develop a blue/green patina.

The new Ram Quarter mixed-use development at the heart of the London Borough of Wandsworth is highlighted by its rooftop cladding of green pre-patinated copper, reflecting the site’s industrial heritage. It also demonstrates the capabilities of copper cladding for urban housing. The site was formerly home to the Young’s brewery and its regeneration has encompassed the restoration of historic buildings alongside the construction of stunning new-build apartments. The three phases of Ram Quarter will deliver 713 homes, nearly 100,000 sq ft of shops and community and leisure facilities over 8 acres. Greenland Group UK, the developer of Ram Quarter, was keen that the site’s material specification should help to reflect the history of the site and deliver high-quality design and long-term durability. EPR Architects, the appointed architectural practice for the scheme, commented: “The oldest fermenting and brewing vessels within the old brewery were copper. This inspired us to predominantly clad the upper two floors of the tallest residential buildings in Nordic Green Living 1 copper. Adjacent to the historic brewery complex we introduced a playful vertical expression to one of the new buildings – a nod to the industrial vats – raised from the ground with softer rounded corners and vertically-ribbed profiled copper cladding.”
The world’s most advanced collated screw system just got even better!
Simpson Strong-Tie’s Quik Drive auto-feed system is a significantly faster way to install screws. With a multitude of modular fittings and screws for a huge range of purposes, there is a Quik Drive kit to suit just about every application – from drywall installation to mezzanine floor construction. A perfect alternative to traditional nailing and screwing. The ergonomic design allows the installation of screws into walls, floors and ceilings without the need for bending, stretching or crouching. Which means not only can the system operate for several hours at a time – so can you. The Quik Drive system fits onto all leading dry wall drivers with just a click. The patented screw strips are designed to avoid jamming, and unlike many collated screw strips, a partially used one can be saved for reuse later – so it’s cost effective too. Sales Manager, Phil Chambers, explains: “The Quik Drive system has been on my radar for some time, it’s not just fast, it’s really (really) simple to use. It’s great to see the lights go on in peoples mind when they give it a try.” In addition to Phil conducting Quik Drive demonstrations throughout the UK, an all-new catalogue now features additional Quik Drive equipment and collated screws, including some tools that can be used to install construction connectors.

www.strongtie.co.uk Shelforce – saving Local Authorities money
A leading manufacturer of PVCu windows and doors based in Birmingham is continuing its legacy of saving Local Authorities money on building projects. Shelforce specialises in providing high-quality products to local authority building projects, including social housing, around the country. The company, which is situated on the outskirts of Erdington, is Birmingham City Council’s chosen manufacturer of choice and they have a reputation for providing quality products for local authority projects and finishing them on time and within budget. For Local Authorities that want to save money, Shelforce’s Eurocell Eurologik profile system not only offers high performance but huge value for money too. The advanced six-chambered system and innovative PVC-U Thermal Inserts work together to lock in heat which maximises thermal performance making the window incredibly energy efficient. This means that a cheaper glass unit can be used, and the window will still achieve an ‘A+’ energy rating. The slim, six-chambered outer frame costs no more than the standard Eurologik outer frame too, so there is no cost barrier to installing the highest energy efficiency-rated profiles. Sustainability is also a big consideration for Shelforce, and the company uses new profiles made from recycled material from unwanted PVC-U frames thanks to Eurocell’s very own recycling plant. Shelforce have also been leading the way in inclusivity when it comes to training and employment opportunities in the glazing industry, with 75 per cent of its workforce disabled.
