Caldmore Primary Academy

Kingspan OPTIM-R Roofing System was used as a space-saving solution in this primary school.

The Project

When a rise in the local population forced Caldmore Primary Academy to double its intake of pupils, architects at Walsall Council were faced with the challenge of extending the building in the already limited school grounds.

Kingspan OPTIM-R formed a key part of their solution, ensuring a smooth transition from the first storey classrooms to an outdoor “play deck”, without compromising either space or thermal performance in the rooms below.

The two storey extension was constructed on a steep embankment between the playing fields and the school. This allows the lower level classrooms to open directly out onto the playing fields whilst the floor level of the first storey rooms matches those in the existing school building. 

The ‘play deck’ sits on the roof of the lower level corridors and ancillary rooms and to minimise heatloss from these rooms without exceeding the height threshold of the classroom floors, Kingspan OPTIM-R Roofing System was specified along with tapered Kingspan Styrozone. 

Stoneleigh Services installed 30 mm thick Kingspan OPTIM-R panels above a vapour control layer on the concrete roof slab and a further layer of tapered Kingspan Styrozone, in thicknesses from 30 mm to 160 mm, was then laid above this. This layer of tapered insulation ensures effective drainage of surface water which filters through a porous rubber play surfacing.

The build-up delivers outstanding thermal performance with a final U-value of just 0.16 W/m²·K.
