Clifton Library building Nottingham Trent University was replaced with Derbigum Olivine mineral roofing membrane

The complete design package was installed by M&J Roofing Ltd after Alumasc identified Derbigum Olivine was as the right waterproofing solution which offered added environmental benefits including:

  • bituminous membrane with a naturally occurring mineral upper layer that neutralises CO2 in rainwater, via an irreversible chemical reaction
  • membrane offers a 30-year life expectancy
  • 100% recyclable

M&J Roofing’s MD Peter Henrickson: “Insulation was incorporated into all of the edge details to avoid cold bridging and the potential for condensation. To address this issue, the increased height of the edge detail was covered by a bespoke Alumasc aluminium polyester powder coated fascia board, supplied in a colour to match the new window installations.”

Project Manager Dean Throop from the University’s Estates & Resources Department: “The new roof is a robust specification to ensure the water integrity of the building, whilst also helping us to reach our 2020 target of a 48% reduction in CO2.  I had no reservations about using Olivine, which is backed up by a full Alumasc warranty.  The Clifton Library is one of the most heavily used buildings on the campus and it’s reassuring to know that we have greater protection from water ingress, as well as the additional benefit of boosting NTU’s sustainability.”

Alumasc’s full system solution also included their Fascia system, Rooflights and Harmer Roof Outlets.
