Kingspan Kooltherm K15 Rainscreen Board has been installed on Glasgow’s £842m Queen Elizabeth University Hospital, helping it on its way to achieve a BREEAM ‘Excellent’ rating.
The Queen Elizabeth University Hospital is Scotland’s largest hospital. The 166,000m2, 14 storey building was designed by IBI Group and will manage 110,000 A&E patients every year. The hospital features an extended quadrangular star layout, which ensures all patient rooms have external windows.
Kingspan Kooltherm K15 Rainscreen Board was installed on a range of façade systems on the external walls of the hospital, contributing towards the overall U-value of just 0.15w/m2.k. Insulating the building with Kingspan Kooltherm provided the necessary thermal performance needed to assist in the award of credits in the Energy section of the BREEAM assessment.
The K15 Rainscreen Board has been assigned the highest possible 2008 Green Guide Summary Rating of A+ and is certified ‘Very Good’ under BES 6001: Responsible Sourcing of Construction Products standard, meeting the requirements of the ‘Embodied Impact’ and ‘Responsible Sourcing’ BREEAM credits.
Specialist contractor Prater was met with additional challenges due to the hospital’s unusual quadrangular star design. Prater’s operations manager, William Morrison, discussed how the Kingspan Kooltherm K15 Rainscreen Board helped them to meet the requirements:
“The shape of the building with many curves, angles and land locked areas made the need for lightweight, flexible and robust material imperative. Kingspan Kooltherm K15 Rainscreen Board provided the necessary thermal performance, ease of site installation and, most importantly, resilience to the West of Scotland weather until such time the overcladding was completed.”
Kingspan Kooltherm K15 Rainscreen Board was the first insulation board to hold LABC Registered Detail for use in rainscreen systems, which help to fast-track the building control checking and approval process. Its fibre-free insulation core is manufactured with a blowing agent which has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).
The application of Kingspan Kooltherm K15 Rainscreen Board was delivered under budget, five weeks ahead of schedule by Brookfield Multiplex.
