The Walnuts School Case Study


The client wanted the roof of this new building to not only be of the highest quality but also designed to be aesthetically pleasing and echo the ethos of the school based upon respecting your environment. Insulation needed to be incorporated into the roof build-up in order to satisfy building regulations and work hours had to be agreed to keep disruption to a minimum. The work also had to be completed to strict deadlines to ensure that the school would be open in time for the start of its inaugural term at its new location in Hazeley.


Due to the building’s exposed location, wind uplift calculations were performed prior to work commencing, making sure the new roof could resist extreme weather conditions. Bauder’s high quality single ply PVC system, Thermofol, was specified because it is robust, has a life expectancy in excess of 30 years and is suitable for extensive green roof landscaping options. The system build-up included Bauder’s 100mm PIR FATE insulation for superior thermal performance, ensuring the roof achieved the required 0.25 U-Value. Despite design and logistical challenges, the new roof system was delivered on time and to budget with all deliveries scheduled as not to conflict with vehicles moving in and out of the facility
