The refurb involved installing an external insulated aluminium rainscreen cladding system and replacing the existing single glazing.
As the university's facilities department was particularly interested in improving the building's thermal performance, a thermographic survey was commissioned to monitor improvements as the work progressed.
NorDan windows were specified for the project for a combination of reasons, explains Pete Hillyard, managing director at D&B Facades, including performance, value for money, longevity and environmental impact.

He said: "We have to be confident that what we install will not require constant revisits for repairs, maintenance or adjustment. We've worked with NorDan a number of times before, in schools and universities as well as on high rise residential projects, and in our experience NorDan windows are extremely robust and deliver what they promise - high performance, long life and low maintenance.
"We are also very keen to ensure the products we select have the lowest carbon footprint and are from a sustainable source. We know that with NorDan, recycling is prioritised in manufacture, with waste materials recycled in the factory, plus at the end of the product's useful life, as it's timber, it's easily recyclable."
The refurbishment of the Cottrell Building was delivered 12 weeks ahead of programme and within budget.
