The Kingspan TEK Building System of Structural Insulated Panels (SIPs) has been erected in just three weeks to form the structure of a new office building at the Royal Horticultural Society’s (RHS) flagship gardens in Wisley.
RHS Wisley is currently undergoing a major renewal programme, including re-landscaping its grounds and the construction of new laboratory and learning spaces. As part of this work, Evelegh Designs collaborated with design and build contractors, Ashley Group, to create a single storey office building for the site’s 72 staff members. Whilst the building has the appearance of a traditional barn, its construction is thoroughly modern with the walls and roof formed from 142 mm and 172 mm Kingspan TEK Building System panels respectively.
Kingspan TEK Building System panels feature an OSB/3 facing bonded to a highly insulated core. The panels were factory cut to the office building’s design, including space for the specified windows and doors. This ensured a straightforward erection programme once on-site and allowed Ashley Group to erect and weathertight the building shell in a matter of weeks.
The excellent thermal performance provided by the Kingspan TEK Building System was another key benefit as Tony Frend, Contracts Manager at Ashley Group explained: “The original tender specified that the walls needed to achieve a U-value of 0.22 W/m2.K. The Kingspan TEK Building System was our preferred specification as, in addition to providing a reliable build programme, the 142 mm wall panels also allowed us achieve an enhanced U-value of 0.19 W/m2.K on the walls. For the roof construction we were able to go one step further, installing the 172 mm Kingspan TEK Building System panels to achieve a U-value of just 0.17 W/m2.K.”
The OSB/3 facing of the Kingspan TEK Building System panels supports a wide range of façade options. To complete the barn’s rustic external aesthetic, black weatherboarding was installed on timber battens fixed to the facing of the panels, whilst clay tiles were used to clad the roof.
Kingspan TEK Building System panels also feature a unique jointing system which, in combination with their OSB/3 facing, can help to create highly airtight buildings. The manufacturing facility where the panels are produced carries both FSC® (FSC®-C109304) and PEFC Chain of Custody certification. As standard, the OSB/3 facing of all Kingspan TEK panels is PEFC certified.
