Alumasc Green Roof Tops Europe’s Largest Urban Shopping Centre

Alumasc Green Roof Tops Europe’s Largest Urban Shopping Centre

A Blackdown green roof from Alumasc has been chosen for Westfield London - Europe’s largest urban shopping centre.

The excellent track record of Alumasc’s Blackdown systems and Derbigum Rapido waterproofing, made them the natural choice for this prestigious project, meeting the need for a lightweight and commercially competitive waterproofing solution.

Spanning over 149,000m2, Westfield London is a £1.7billion development featuring an impressive mix of retail, leisure and restaurant space in West London. Westfield worked with international architects Benoy and The Buchan Group, to design and deliver the innovative curved undulating glass roof above the shopping centre, which earned the project a position as finalist in the LABC National Building Excellence Awards. The award organisers described the roof as “part of a sustainable design that has paved the way for 21st century retail design in the UK.”

Landscape Contract Designs (LCD) of North Yorkshire installed 15,600m2 of extensive and bio-diverse green roof onto the structural metal deck roof. The system features sedum plug plants which will flourish over time, offering notable ecological benefits, providing a natural habitat for plants and wildlife, whilst also helping to reduce air and noise pollution, cutting carbon emissions and assisting with rainwater retention and attenuation.

Blackdown green roofs vary from the extensive and biodiverse types used at Westfield - which require minimal irrigation and maintenance - to intensive roofs, which are suited for areas of public and recreational use and require more tending.

Derbigum Rapido waterproofing, also from Alumasc, was installed by leading building envelope contractor Prater Ltd of Surrey, for the warm roof build up. This high performance single layer membrane gives exceptional long-term performance and durability, warranted for 25 years. Derbigum is BBA Approved and manufactured under the ISO 14001:2004 Environmental Management Standards. Furthermore, Derbigum is fire rated F.AA to BS476 Pt3 (EN1187 Pt4), the highest available rating, which allows unrestricted use under Building Regulations.

Throughout the project, Alumasc worked closely with the contractors to ensure that products were supplied to suit available crane time-slots, contributing to the successful completion of the project within deadline and budget.
