James Jones Timber Systems supplies one of the UK’s largest cassette-built school roofs

Sandfields Primary School Port Talbot is one of the largest projects of its kind to have a roof built using roof cassettes. James Jones & Sons Ltd, Timber Systems Division, undertook the fabrication drawings for the project and supplied their UK manufactured, FSC registered JJI-Joists to cassette manufacturer NYT (North Yorkshire Timber) in 220mm, 350mm and 450mm sizes. NYT in turn produced 4000m2 of roof cassettes in varying lengths up to 12m, for roofing erectors and SIPS suppliers Hemsec Installations.

This £7m project for Neath Port Talbot County Borough Council had a 61 week contract period and was all delivered to programme by main contractors Dawnus Construction, reaching completion this Autumn, in good time for the new 2013 school term.

The building fabric is SIPS (structural insulated panel systems), one of the most energy efficient and sustainable forms of building. The school will house over 300 primary school pupils, and incorporates photo voltaic cells, underfloor heating and a rainwater harvesting system, and is expected to achieve a BREEAM rating of “Excellent”.
