A Roof For All Seasons

The UK’s first Olivine roof was supplied by Alumasc Roofing Systems.

Alumasc has supplied a pioneering new flat roofing system, with unique environmental benefits, for thecentre:mk shopping centre in Milton Keynes.

Derbigum Olivine is an ecological roofing solution. During rainfall, the Olivine mineral membrane makes contact with CO2 present in the atmosphere resulting in a chemical reaction that neutralises up to 1,750kg of CO2 over the lifetime of the roof.

Joint owners of thecentre:mk, Hermes Real Estate Investment Management and Prudential Property Investment Managers, were replacing the original roof as part of a re-roofing programme when the Olivine roof was suggested as an alternative.

Richard James, Managing Surveyor at M&J Flat Roofing, an Alumasc registered contractor, explains: “The Centre Management approved the installation because they thought the concept of Olivine’s CO2 neutralising properties was unique and fitted with their carbon neutral stance. The system also proved to be more cost effective than the previous roofing system and was simple to install.”

Installing over 1000m2 of the Derbigum Olivine membrane at the shopping centre scheme did, however, present some challenges. Alumasc’s Southern Region Manager, James Donovan, explains:

“Modern roofs are designed with a fall to allow efficient drainage of rainwater, however roofs designed in the 1970s were notorious for poor fall and this was the case on the Milton Keynes scheme. To combat this, Alumasc specified a pitched insulation solution to assist with rainwater run-off, which in turn will help prolong the life expectancy of the roof.” Like all other Derbigum membranes, Olivine is easy to apply, highly durable and 100% recyclable.
