Schöck and cross-laminated timber feature at Hoxton cinema

The neglected Hoxton Cinema in East London is undergoing a transformation, with plans for a replica of the original 1914 Gaumont façade to be reconstructed. Behind it will be a development of black-brick one, two and three bedroom apartments – and in the basement a new three-screen arthouse cinema.

The design consists of two distinct elements. A concrete ground level to accommodate the cinema and an acoustically insulated cross-laminated timber (CLT) upper residential element. The balconies on the western elevation are of steel construction; and unusually the requirement here is to connect the balconies to the CLT. Cross-laminated timber performs well thermally, but the steel cantilever penetrates the insulation layer and it is important to minimise the risk of any thermal bridging problems at this point.

One of the leading solutions for preventing thermal bridging involving practically any cantilever connectivity, is the Schöck Isokorb range. It is the type KST – usually for steel-to-steel connections – which has been cleverly integrated here. A right angle steel retaining plate has been fixed to the CLT outer wall and floor using heavy duty screws. The inner face of the Isokorb is then bolted to the retaining plate and the steel balcony connected to the outer face of the module. The result is a more rigid structure and the prevention of increased heat loss or, just as importantly, condensation. Particularly where it might occur under the steel retaining plates at the connectivity points with the CLT.

The Schöck Isokorb range meets full compliance with all relevant UK building regulations, the highest standards of BBA Certification and offers LABC Registration.
