A wide range of products from Kingspan Insulation’s Kooltherm and Therma ranges have been installed on the RIBA award winning Kingswood Academy in Hull.
The school, which was built as part of Hull City Council’s ‘Building Schools for the Future’ initiative, gained Academy status in June 2013. Designed by Allford Hall Monaghan Morris, its powerful form is accentuated by the striking saw toothed roof with seven pitches.
To insulate the building’s metal rainscreen façade, Roofdec Ltd installed over 900m² of 100mm Kingspan Kooltherm K15 Rainscreen Board. The product offers premium performance with thermal conductivities as low as 0.020 W/m.K and is LABC System Approved, helping to speed up the Building Control checking and approval process. Its rigid thermoset phenolic insulation core is also rated Class O as defined by the Building Regulations, and has negligible smoke obscuration.
To make full use of natural light, the brick facia to the main entrance features multi-storey glazed sections and to minimise the heatloss from around these windows, 75mm Kingspan Kooltherm Cavity Closer was installed. The product ensures a continuous insulated cavity around the windows without the need for cut blocks or special reveals and has a one hour fire rating for cavities up to 150mm.
John Barnes from Roofdec commented:
“As with all installations on education facilities, this project combined high thermal and fire performance requirements with a relatively tight completion deadline. The Kingspan products are easy to handle and allowed us to meet all of the project’s targets with ease, including the BREEAM ‘Very Good’ rating.”
The fibre-free cores of Kingspan Kooltherm K15 Rainscreen Board and Kingspan Kooltherm Cavity Closer feature a closed cell structure which prevents air infiltration. Both products also are resistant to moisture and water vapour ingress, helping to ensure long-term performance when installed correctly.
To complete the building envelope Roofdec also installed Kingspan’s high performance Thermaroof TR27 LPC/FM on flat areas of the building’s iconic roof. All Kingspan products installed on the Academy have been assigned 2008 Green Guide Summary Ratings of A or A+ and are certified ‘Very Good’ under BES 6001: Responsible Sourcing of Construction Products standard, helping to contribute towards BREEAM credits for Responsible Sourcing and Embodied Impact.
The building received a ‘Performance Beyond Compliance’ certificate as part of the Considerate Constructors Scheme and has also been awarded a 2013 RIBA National Award and a 2013 RIBA Yorkshire Award.
