Cardiff Bay apartments weatherproofing
Architect Goddard Manton has used StoTherm Classic external wall insulation on its latest housing scheme in Cardiff Bay. The Sovereign Bay 60-apartment development rises up to seven storeys in height and has curved facades. The Sto render is fixed to lightweight metal stud and masonry, so both adhesive and mechanical fixings were used. For additional protection against weathering, the StoRend Flex Cote was applied after rasping. Flex Cote is a specialist anti-crack render system that consists of a levelling coat applied to the substrate, followed by a 3 mm coat of StoElasto, a cement-free, water-based and fibre-reinforced render. Sto Glass Fibre Mesh was then embedded into the StoElasto to which an acrylic, decorative finishing plaster called StoLit was sprayed.

Extra-long cladding in production
Euroclad has opened a production line to enable it to manufacture 12 m-long composite cladding panels. The 拢4m manufacturing facility can produce Rockwool-cored panels up to 200 mm thick and is capable of producing up to 20,000 m2 a week.

Euroclad claims
that more specifiers will be forced to specify non-combustible steel and Rockwall panels as insurers continue to push up premiums for buildings constructed with sandwich panels such as polyurethane, polystyrene and polyisocyanurate.

Brise-soleil made of aerofoil fins
Levolux has supplied a bespoke facade for two buildings at an out-of-town business park at Quinta da Fonte near Lisbon. Levolux had to provide sunshading to the south facing facades, one of which is curved. The
solution involved 600 mm aerofoil fins with spans between 7.5 m and 9 m incorporated in a brise soleil, which projects horizontally from the building by 7.5 m. Steel columns support the brise-soleil 12 m above the ground. The fins were made in three parts that clip together. These are supported between rectangular hollow sections of steel which are fitted back to the cladding of glass and local stone.

Automatic blind and window control
Somfy has launched a system that automatically controls interior blinds and windows to control the light, temperature and ventilation of a building. The Animeo IB+ system can drive eight separate zones around a building, operating blinds and opening windows according to light levels, interior and exterior temperatures and the strength and direction of the wind. The system is controlled by software hosted on a local or remote PC and can be linked to air-conditioning and heating systems. The weather information is transmitted to the system via sensors outside the building or inside a switch cupboard.

What鈥檚 the spec?

King鈥檚 Cross Community Learning Centre
The cladding specified at the King鈥檚 Cross Community Learning Centre in London is rather like a soft-centred sweet. The building鈥檚 hard exterior is made up of fibre-cement panels and curtain walling, whereas a cr猫che on the interior of the centre has walls of flexible, yielding polycarbonate cladding. Although the polycarbonate looks delicate, architect Gollifer Langston says it is robust. Originally it was going to be used to clad the exterior but the feeling was that a more solid looking material should be used to deter would-be vandals. Gollifer Langston says it was attracted to the fibre-cement panel because it combines a stone-like appearance with a clean, sharp finish. The panels are coloured all the way through, which ensures that the fibre-cement won鈥檛 fade over time, and that any scratches and pockmarks will be hard to detect. To meet target U-values, three skins of polycarbonate were used to make up the cr猫che wall. The transparent polycarbonate allows children to peer outside the structure and is flexible enough to sustain direct hits from toys and wayward infants. Privacy was provided for the toilet block of the stand-alone timber structure by Rockshield insulated render. The cement fibre panels used on the main building were insulated using Celotex semi-rigid insulation. Project team

Tips for planting facades

Ivy draped over pubs and homes may be easy on the eye but the roots of the climbing plant are likely to be destroying the fabric of the buildings. Architects that include 鈥済reening鈥� in their designs need to be careful what plants they specify. Ivies, for example, can grow into the brick joints and eventually crack the building facade. A guide from wire cable manufacturer Jakob offers detailed information on specifying climbing plants and offers the following advice for architects thinking of mixing nature and mortar:
  • To avoid damage to the facade, Jakob suggests using vines (twining plants), leaf-stem climbers, leaf climbers and scrambling plants in conjunction with its Inox Line of steel ropes and fixings. Adhesive sucker climbers and root climbers should be avoided. Greening specialists should be consulted when the plants are chosen.
  • Growing conditions should be as near as possible to those found in the climbers鈥� natural habitat. Generally good supplies of water and nutrients are important.
  • To determine the dimensions of the training system consider the following: the vigour, size and climbing pattern of the desired climber; the architecture 鈥� for example balcony or high-rise buildings 鈥� and the aesthetics of the plant. The dimensions to be determined are the height and width of the climber supports, distances from wall, wire rope spacing for vines, lattice size and wire rope or rod diameters.
  • Consider the overall load of the plant and training system before specifying materials. The load will be made up of the plant weight, wind load on plant surface, weight of dew and rain, weight of snow and weight of training structure.
  • An engineer should also consider whether the plants are deciduous or evergreen, the orientation of the site, and the most appropriate rope or rod grid aperture for the chosen plant.
  • The weight of the plants will increase over time and it may be necessary to retention the wire ropes or add anchors and reinforcement elements. For more information and a copy of the guide contact sales@mma.gb.com 0845-1300135. Jakob

    Liverpool arts wrapped in zinc sheets

    CGL Cometec has supplied the zinc tiles for the new Foundation for Art and Creative Technology building in Liverpool. The zinc sheet cladding wraps around the face of the building. A total of 2823 tiles of 41 slightly different shapes are held on vertical rails to create a rainscreen. Working like traditional roof tiles, they allow air to circulate behind them while shedding water in the event of rain. A computer model of the facade produced by architect Austin-Smith:Lord was used by CGL Cometec to cut each tile. The cladding tiles were cut and folded by an automated machine working directly from computer drawings. CGL Cometec
