With almost 1700 students, including 300 in the Sixth Form, The Billericay School is one of the largest schools in Essex. To ensure there was not only enough space to accommodate such a large volume of students, but that the facilities matched the high quality of the teaching, the school called upon the help of Sprunt Architects. Their design included the refurbishment and extension of an existing three-storey building known as Block C, creating new classrooms and science laboratories. In addition, a new state-of-the-art building was constructed to accommodate the modern languages and music blocks
Building Innovation designed, created and supplied two different single-ply build ups for the roofs of the new buildings. For the Block C extension, a tapered insulation solution was selected. The system incorporates polyisocyanurate (PIR) insulation
beneath a fully adhered single-ply membrane to a design fall of 1:80. The system both ensured that the roof easily met the thermal requirements of current Building Regulations, achieving a U-value of 0.18W/m²K, and created falls for drainage to prevent the potential issue of ponding.
For the newly constructed areas of the school, Building Innovation’s tapered ASPIRE Solution
was installed by Voland Roofing, matching the thermal performance of Block C. The hybrid tapered system combines an Expanded Polystyrene (EPS)
base layer with a flat PIR top layer to deliver a cost-effective and high-performance solution designed specifically to meet the requirements of the project.
