Contractor: Ashgate Roofing Systems
Type of works: supply of 14,000m² Rhenofol CGv roof membranes.

SIG Design & Technology has played a key role in a £109m PFI-funded hospital development in Oxfordshire that will revolutionise cancer care.

The Cancer Centre, being developed on the Churchill Hospital site, part of the Oxford Radcliffe Hospitals NHS Trust, was designed with the help of cancer patients, and brings together cancer services previously provided by the Trust’s John Radcliffe and Churchill Hospital sites in Headington, near Oxford.

The 14,000m² roof features a number of paved roofs with access for staff or patients, and a 600m² roof garden donated to the hospital. Ashgate Roofing Systems Ltd installed Rhenofol CGv to all areas other than the roof garden and paved roof sections.

The membrane, selected for its ease of application and longevity, was bonded to 90mm insulation on a 2mm torch-on vapour barrier with a concrete substrate. The terrace roofs are protected by rubber mats and generally inverted. The roof garden was installed by external specialists and fitted over a completed Rhenofol CG roof protected by insulation and 35mm rubber safety matting.
