The Walnuts School
High quality new build school in Hazeley using Thermofol Single Ply, XF 301 sedum blanket and PIR insulation.
Synopsis
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.

The specification
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 Thermofol PVC single ply waterproofing system was specified because it is robust, has a life expectancy in excess of 30 years as stated in BBA certificate 06/4354. The PVC formulation ensures it is resistant to chemicals and micro-organism attack making it ideal for green roof situations. The system build-up included BauderPIR M 60 insulation for efficient thermal performance, ensuring the roof achieved the required 0.25 U-Value.
Products applied
Integrated single ply waterproofing system, featuring 1.5mm membrane offering high tensile strength of over 1100N and can be guaranteed for up to 20 years depending on system type.
A lightweight, easy to maintain sedum blanket that provides instant greening to the roof.
The result
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.
