A hybrid roofing membrane from Sika was utilised to provide a watertight finish for a new school built using offsite construction techniques.
To meet performance and programme goals for The King Edward VI Northfield School for Girls in Birmingham, a hybrid design was devised by offsite and modular specialist Innovaré.
Innovaré’s hybrid system included integrated BBA-Certified i-SIP panels, hollow core concrete plank floors, and a lightweight timber cassette roofing system.
Sika’s 4mm elastomeric and plastomeric bituminous hybrid membrane, SikaBit Pro 940, provided the finish for the roofing system, which integrates timber cassettes with i-joists.
Sika said the product combines the advantages of APAO and SBS-modified bitumen, allowing two different compounds to work together.
RLW Roofing was responsible for the design and installation of the roofing system. The firm also completed façade works, using Sika Parex Historic Mortar KL.
