When completed in the next ten years or so, the regeneration of Wembley Park, in North West London, will provide up to 7000 new homes. Isokorb structural thermal break systems from Schöck are being supplied across a number of sites on this vast scheme, but one of the largest is South West Lands. This residential-led mixed-use neighbourhood occupies an area running alongside the Chiltern rail line, adjacent to Wembley Stadium and will account for around 12% of the new homes (up to 900 in total) on the entire development. Designed around a series of sheltered and south-facing garden squares, it is set in landscaped areas and residents will benefit too from a centralised ‘hub’ offering facilities including a gym, cinema and concierge services.
South West Lands is spread across four separate blocks and the reinforced concrete frame buildings, up to 18 storeys high, are finished using traditional brickwork and standing seam metal cladding. To create amenity space at higher levels, as well as offering far-reaching views, there are communal roof terraces and a considerable number of private balconies throughout the development.
Avoidance of thermal bridging is crucial
As with any large-scale project involving so many balconies, minimising any possibility of thermal bridging is crucial. Poor insulation at the connection points result in local heat loss, with more energy being required to maintain the buildings internal temperature. In addition, low internal surface temperatures around the thermal bridge can create condensation, causing structural integrity problems with absorbent materials such as insulation products or plasterboard. It also encourages mould growth, which can have serious health implications for residents, particularly older people and children, in the form of asthma and allergies,
Construction dependability and design freedom
As the leading international supplier of structural thermal breaks, Schöck has almost limitless variants available in its main Isokorb range, offering planners construction dependability and freedom of design. The hundreds of Isokorb products used on two of the phases at South West Lands are for connecting cantilevered steel balconies to a reinforced concrete slab by means of straight tension and compression bars, which are inserted into the on-site reinforcement. The steel balconies are then bolted onto the unit by means of a stub bracket.
Proven performance and unrivalled choice
In addition to concrete-to-steel, the comprehensive Schöck Isokorb range also offers solutions for concrete-to-concrete, steel-to-steel – and even a maintenance free alternative to wrapped parapets. All products meet full compliance with the relevant UK building regulations, have NHBC approval and offer LABC Registration. There is also the security of independent BBA Certification. The temperature factor used to indicate condensation risk (fRSI) which must be greater than, or equal to, 0.75, for residential buildings, is easily met by incorporating the Isokorb.
