The New Woolwich Central development, which is located 10 miles east of central London, includes 400 apartments and a Tesco Extra hypermarket. Beneath the store is a car park, which is split across two floors, boasting 600 parking spaces.
The Woolwich Central development required high performance insulation to be installed between the floor of the new 85,000 sq ft Tesco store and the underground car park. Installed on the concrete soffits and ceilings between the two areas, the purpose of the insulation was to enhance the shopping experience by preventing noise and cold air from passing from the car park area into the supermarket. The design was to achieve a BREEAM rating of ‘Very Good’. The scope of the project and the many different trades involved meant that there was an added requirement that the chosen insulation be quick and easy to install.
Having worked with main contractor Willmott Dixon on a previous mixed use Tesco development In London, Sharpfibre was contracted to advise on and install the insulation layer. After close consultation with Celotex Technical Centre, Sharpfibre specified 15,000m2 of Celotex FR5000 in a thickness of just 80mm. In doing so we were able to ensure that the target U-value of 0.25W/mK was achieved, whilst reducing costs and minimising waste.
Thanks to textured aluminium foil facings, which offer low emissivity, Celotex FR5000 has a low thermal conductivity value; ensuring a low heat transfer which serves to prevent condensation, whilst offering maximum thermal performance. The aluminium foil facings, which can be cut to fit even the most intricate areas, also meant that there was no requirement for additional facings, thus keeping installation time down.
Sharpfibre’s experience of working with Celotex products and our early consultation with their Technical Centre ensured that the project was completed on time. The installation achieved the required U-value of 0.25W/mK, with the processes used contributing to the BREEAM rating of ‘Very Good’.
Works began in August 2012 and were completed in February 2013.
