National Trust Visitor Centre
Carlisle Construction Materials Limited
The National Trust visitor centre at Tarn Hows in the Lake District is set in a protected Site of Special Scientific Interest (SSSI). EPDM was specified for the roof because of its environmentally friendly credentials which have the backing of Greenpeace. Hertalan roofing products were chosen because of ISO9001/14001 and BBA certification. The membranes were a combination of factory vulcanised sheets and easy weld rolls which were installed in accordance with strict FLL/GRO guidelines. The specification for the green roof insisted on local species of sedum and had over 2000 plug plants installed into 150mm deep recycled growing substrate.
