System upgrade for larger glass and triple glazing Reynaers has announced that its multi-chamber, high insulation aluminium doors and aluminium window system, CS 86-HI, is now able to accommodate larger glass panes, including triple glazing and pivoting window options. A special modification to CS 86 now allows the installation of glazing panels from the outside, avoiding the need to transport glass through buildings. The development also reportedly allows the use of larger and heavier glazed panels, including triple glazing up to 500kg, offering greater flexibility in terms of both design and installation. Pivoting openers with hinges fully integrated into the profiles have also been introduced. Depending on the position of the hinges, the pivot window can be supplied with a horizontal axis (max. 200kg), or a vertical axis (max. 160kg). The new system helps create a more flexible building design, allowing glass panes up to a maximum height of 2,500mm. Used extensively on energy efficient and BREEAM rated buildings, Reynaers CS 86-HI aluminium windows and doors incorporate a unique insulation designed to ensure ‘extreme’ stability and enhanced water and air tightness. The performance of the system for air and water tightness has subsequently been upgraded to 300 Pa. Several of the CS 86-HI window and door configurations achieve the Minergie and Minergie-P component labels, which correspond to Passivhaus standards of a ‘U’ value of ≤0.8 W/m²K. Variants of CS 86 are also compliant with the Secured by Design initiative. 52 ALUMINIUM Aluminium – a trusted material with future proof capability By Alison Davey, national sales and marketing manager at The Parkside Group Aluminium is the ubiquitous construction material, constantly evolving with design. It is a building material that offers the designer reassurance as well as catering for new demands. For construction professionals, gaining a grasp of its capability is a future proof skill. Lifespan of aluminium Not only is design aspiration catered for, but this is a material which is both sustainable and offers longevity. In a Delft University pan-European study, 86% of aluminium used in the old Wembley stadium was recycled and reclaimed. Longevity and lifecycle analysis is also favourable with standard 25-year guarantees for polyester powder coated aluminium and 35 year guarantees for anodised applications. The lifespan of aluminium, if properly maintained, can be indefinite: the top of the Empire State Building was one of the first examples of anodised aluminium and is still a gleaming, eye catching feature today. If one considers the building envelope, large glazed screens, canopies, windows and focal entrance points can all be achieved through installing and integrating aluminium ground floor treatment, curtain walling, windows and doors. The envelope can be expanded with roof glazing to incorporate pitched, barrelled or pyramid vaults. These areas can be as sleek as the designer requires. Aluminium has a naturally high strength to weight ratio so large glazed spans and multi-storey applications can be achieved with slim sightlines. The opportunity to polyester powder coat or anodise means that a multitude of shades can provide contrast or minimal visibility to the project. Panels and glass also offer an amazing area of options. Glass can be mirrored or tinted to suit the envelope, whereas panels can provide solid colour or a mirrored glass effect. Aluminium has the ability to integrate both panels and glass into the same facade; a variety of gaskets ensure that most applications can be catered for. Myriad of options Aluminium is robust and is ideal for high traffic applications, such as retail, school or hospital. If one considers entrance doors, available in configurations such as swing, sliding, sliding/folding, the robust profiles ensure longevity even with endless open and closing cycles. Windows also offer a myriad of options; tilt and turn, top-swing reversible, sliding and pivot windows have been around for many years. Aluminium systems houses also work closely with gearing manufacturers which means that there are tried and tested solutions for providing ventilation without jeopardising security. In multi-storey applications the configuration selected, for instance top-swing reversible or pivot, has options to fully reverse the external surface to allow cleaning from the inside. www.ggpmag.com August 2015 In essence, aluminium is the building material that, through its long use, has developed to provide function, form and solutions for even the most demanding projects. Systems Houses, such as Comar Architectural Aluminium Systems, continually develop and refine their profile catalogues to meet the demands of cutting edge designers, providing support and calculation at any stage of the tender process. Now, with improvements in glass and to keep up with Document L, systems can utilise thermal foam and increased thermal break technology to take performance to Code for Sustainable Homes Level 6. With the EAA’s (European Aluminium Association) ‘Future Generations’ initiative, aluminium’s long reputation as a recyclable material is gaining further exposure. Future Generations, is a scheme which highlights that the use of aluminium is actually creating a bank of material that can be re-used and recycled in the future.
