University of Cambridge
Client: Cambridge Uni: The £16m phase-one project, designed by Arup Associates for the University of Cambridge, provides a world-class facility under one roof for hundreds of athletes from the University and local community.
System Used: SFS, cement board and 4500m2 ewi
As well as constructing the SFS Metsec Frame and cement particle sheathing board we were responsible for the installation of the award-winning BBA certificated, weber.therm XM EWI system for this iconic sports building which has been designed with an integrated approach to sustainability, engineering and architecture. weber.therm XM EWI is a lightweight system that incorporates thin-coat polymer render with a meshcloth reinforcement.
EWI eliminates the risk of condensation within the wall structure and overcomes the occurrence of thermal bridging, ensuring a dry and stable structure. More than 4,500 m² of EWI has been installed. The specification has been calculated by Saint-Gobain Weber to attain a low U-value of 0.25 W/m²K. This has been achieved using 120mm thick expanded polystyrene insulation which is both bonded with weber.rend LAC as adhesive as well as being mechanically fixed to the frame panel substrate. The insulation is protected with an initial 3mm coat of weber.rend LAC render into which the meshcloth reinforcement is embedded.
This is followed with a second 3mm coat of weber.rend LAC which completes the render structure. In preparation for a decorative finish the render surface is coated with weber PR310 pigmented primer and then a final finish using weber.plast TF150, an acrylic based, textured finish that provides a weather proof, durable and low maintenance architectural façade.
