Sika-Trocal S single ply roofing membrane provided a watertight solution to a new primary school in Brighton. Specified for its exceptional waterproofing and durability properties, its robust performance, yet flexible application ensured the roof was able to accommodate a solar panel system to increase the building’s energy efficiency and help reduce its running costs.
Specialist roofing contractor, Robertson Roofing installed 2,100m2 of Sika Trocal’s Type S roofing membrane. Quick, lightweight and economical to install, the mechanically fixed Type S system allowed Robertson Roofing to secure the membrane and the insulation with a single, strong and reliable fixing to reduce costs and time on site.
Supplying a roof which was watertight and durable, as well as adding an aesthetic finish to the building was among the challenges faced by contractors Robertson Roofing. This was achieved by extending the Sika-Trocal S up and across a perimeter parapet ranging from 200 to 600mm high.
Mike Nicholls of Robertson Roofing commented: “By dressing the Sika-Trocal S membrane up and fully across the top of the parapet we were able to guarantee the long term water tightness of the detail, avoiding the reliance on the originally proposed butt-jointed traditional aluminium full width capping".
