Client: Large residential scheme
Type of works: supply and incorporation of 1,800 Isokorb^® thermal break modules.

A large-scale residential and mixed use scheme is well under way on the site of the former Prestolite Factory at Larden Road, in Acton, West London. The £71m development involves both new build and conversion. One of the key criteria is that the original factory buildings have to be retained. The scheme provides 499 residential dwellings in total, plus a 500m² commercial space which includes a doctor’s surgery, cafe and retail units.

Landscaping for play areas and communal green spaces is a major feature, as is the requirement to generate 10% of the energy use by renewable means, using open-loop ground source heat pumps and micro-wind turbines. Energy-efficient detailing continues with the facade connections, which incorporate 1,800 Isokorb^® thermal break modules. Construction elements which break the insulation layer, such as balconies and other cantilever connections, are notorious for creating thermal bridges. The result is substantial local heat loss, with more energy needed to maintain the internal temperature of the building and unacceptable levels of CO₂ emissions being produced as well. These are crucial aspects of thermal bridging prevention, but low internal surface temperatures in the area of the thermal bridge can also cause serious condensation. If they are below the dew point of the air, this can lead to structural integrity problems and the occurrence of mould growth, which has serious implications for occupants in the form of respiratory problems.

All of this is combatted by the Schöck Isokorb^® modules which meet full compliance with the relevant UK building regulations and have exceptional thermal performance ratings. The range is also unique in providing thermal break solutions for connections between concrete-to-concrete, concrete-to-steel and steel-to-steel – and it is also able to offer BBA certification for the concrete-to-concrete and concrete-to-steel ranges, with steel-to-steel pending.
