Located near Highgate in North London, the Chester Balmore project consists of three elegant brick-clad blocks, housing a contemporary collection of 53 super-insulated one, two and three-bedroom flats, all set around a landscaped courtyard. The development is designed to achieve Code for Sustainable Homes Level 4 and the high levels of insulation employ good use of solar and internal heat gains, plus excellent air tightness and minimal thermal bridges. It is claimed that the air tightness on the Chester Balmore development is around twenty times better than that required by Building Regulations.
Preventing thermal bridging along the parapets was a critical consideration for such a high performance development, because as with balconies, parapets can allow conductive materials to transfer energy through the thermal barrier. Conventionally, in the majority of cases, the method of insulating parapets and parapet walls is to wrap the perimeter of the wall with an insulation barrier. However, the Schöck Isokorb® T type A offers a cost-effective and more thermally efficient alternative. Its 60mm insulation thickness results in low psi-values and therefore significantly reduces heat loss – and there is no wrapping required. It offers a more sophisticated construction opportunity for greater freedom of design and offers flexible distance between elements according to load requirements.
