A key element of this revitalisation programme has been the protection of the building’s original concrete barrel vault roof. This has been achieved by the specification of a cost-effective, long lasting Kalzip standing seam liner aluminium roof system which has excellent thermal efficiency, the ability to resist high wind uplift and a minimum design life of 40 years.
The challenge
McLaughlin & Harvey Construction and Page\Park Architects were appointed to undertake this extensive and ambitious refurbishment project which provided a demanding set of challenges – particularly regarding the preservation of Kelvin Hall’s internal heritage features and the original concrete shell in its entirety.
Kalzip® AluPlusPatina pre-weathered roof sheets were specified because it was important that the appearance of the outer roof covering blend in sympathetically with traditional nature of this historic structure. The surface of these stucco embossed matt aluminium sheets is highly resistant to weathering and the additional treatment also significantly reduces light reflection.
Two new Kalzip roofs were installed on this first phase of the restoration work – the major central barrel vault which covers part of the main building and the side barrel vault over the huge sports complex.
The solution
By working cooperatively with the other on-roof teams, Lakesmere was able to ensure that the hall’s internal heritage features remained fully protected from potential water damage by coordinating the careful removal of the old steel sheets with the rapid installation of the new Kalzip system thereby avoiding any areas of the roof being left exposed to the elements.
Over 4,400m2 of Kalzip standing seam roofing sheets with an AluPlusPatina finish have been installed on this first phase of Kelvin Hall’s refurbishment.
McLaughlin & Harvey is currently underway with Phase 2 of this extensive redevelopment project – when finished, a further 6,900m2 of Kalzip® roofing will have been installed on the two remaining large barrel vaults over the main hall, helping the historic landmark building to achieve its targeted BREEAM sustainability rating of ‘Very Good’.
