In 2010, the Grade II listed Royal Shakespeare Theatre at Stratford-upon-Avon was transformed to create a new 'thrust stage' main auditorium, as well as to remodel public and back-of-house spaces.
The challenge for the project design was to retain original Art Deco and Victorian elements of the existing 1932 building, and blending these key aspects with new theatre spaces.
Specialist roofing contractor, Varla (UK) Ltd was awarded the contract to design, manufacture and install the zinc standing seam roof and wall package. Varla challenged Knauf Insulation to propose a solution to meet the demanding specification for this unique project.
Knauf Insulation provided detailed ongoing technical support during the design stages of the project and proposed solutions based on the results of three dimensional heat loss calculations.
Knauf Insulation's 3-D calculation support service, provided by the Technical Advisory Centre, was an integral part of the product specification process to ensure that precise thickness recommendations were proposed, in order to meet the project’s specific U-value requirements.
Knauf Insulation provided 160mm of FactoryClad 32 roll, which met all of Varla’s insulation requirements. This flexible, lightweight roll of resilient glass mineral wool has very high tear strength and a thermal conductivity of 0.032 W/mK.
In addition, FactoryClad, recommended for this project, is manufactured from glass mineral wool, which is ideal for limiting the spread of fire since it holds a Euroclass classification A1 for non-combustibility. The product will not burn, give off toxic smoke or suddenly ignite in a fire due to ‘flashover’. For public buildings such as this, superior fire performance is crucial.
The new theatre gives artists and audiences the best environment in which to perform and enjoy Shakespeare with improved public spaces both inside and surrounding the building.
The project was shortlisted for, and won, several awards:
