Byron Square - Cambridgeshire

The BISF house is a steel framed house, designed and erected around the country from 1946. In Cambridgeshire these temporary prefab homes, constructed in 1950, are still standing securely today but lack adequate insulation. This is being remedied with the application of the BBA certified webertherm XM External Wall Insulation (EWI) system.

The homes, owned by Cambridge City Council (CCC), were constructed with a modular steel frame on which the upper storey is clad with corrugated steel sheeting; the lower half of the building is formed with steel reinforced concrete blocks and render. Surveys have calculated that the U-value of the properties, which vary slightly due to construction type, are between 0.72 - 0.79 W/m²K. CCC has prioritised the funding of a thermal improvement programme for 20 of the houses around Byron Square, an attractive memorial green space area on the outskirts of the City.

Weber made system calculations for the Cambridge properties with the aim to achieve a U-value as low as 0.23 W/m²K, a massive 70% improvement that will radically reduce energy costs and enhance tenants' comfort.

The new improved webertherm EPS (expanded polystyrene) grey insulation boards played an important part in the successful aesthetic and thermal upgrade of the project.
