IKO Polymeric’s Armourplan P PVC roofing membrane in slate grey was specified for the roof installation at York Universities Heslington East Campus.

York University has invested in a £27m infrastructure in the Heslington East Campus which is planned as a state-of-the-art learning facility for pre-university overseas students.

The new development – Piazza Building – will provide a 350 seat auditorium, flexible learning spaces including two laboratories, a learning resource centre, a 350 seat lakeside view restaurant, offices spread across 70,000 sq ft.

The new three-storey building was designed as crescent shaped to wrap around a retained oak tree in the courtyard, located to the south of Langwith College on the University campus.

To give the building an aesthetically pleasing and sharp look, aluminium was used on the façade cladding, roof edges and fascia. IKO Polymeric’s Armourplan P PVC roofing membrane in slate grey was specified to compliment the dark grey colour of the cladding and roof edges.

Chemplas, who managed the roof installation, chose Armourplan P membrane to meet the guarantee requirements of the client and contribute to the BREEAM rating of the building.

The crescent shape roof required attention to details and a neat installation which was achieved to a high standard by Chemplas. Armourplan P membrane made the installation easier thanks to its flexibility.

Whilst suitable for extended guarantees, this membrane is still only 1.2mm thick, making the complex detailing easier. With high quality polymer throughout – even on the lower layers – and high performance reinforcement, Armourplan P membrane offers a robust solution.

Due to the campus being exposed to strong winds, a wind uplift calculation was the key for the performance of the single ply roof. IKO Polymeric’s technical team provided Chemplas with a report advising the right number and type of fixings required in different areas of the roof.
