Château de Cangé stands on the site of an original castle built in the 13th Century, which was gradually modified and developed by a succession of owners into the current design. Historically, the château has been home to a large collection of manuscripts and historic documents and the local community has gradually restored the main building and outbuildings since it was severely damaged by fire in 1978.
While the château’s individual architecture and external appearance has been preserved throughout the restoration, the interior of the building has been sensitively extended, modified and re-purposed for its new role as an events centre and ‘mediatheque’ library, which revisits one of it’s former uses.
With the extension of the château’s library and the creation of large public areas within the building, the architects also incorporated an extensive sunscreen design to help provide shade and ensure thermal gain is reduced and the public areas are maintained at a comfortable temperature.
RMIG France worked closely with the architects to create, prototype and develop the final perforated and laser cut patterns within the 130m² of decorative solar shading panels, which are secured to the exterior of the building in front of the large windows, which allows natural light to enter due to the ‘netting’ effect of the perforation pattern used.
Once the final pattern was agreed, RMIG produced the design using a complex array of 15mm diameter round perforations and special laser cut shapes within 2 mm thick ‘Corten’ alloy steel. The architects chose Corten as it is designed to ‘rust’ when weathered, which was ideal for the design as it enhanced the aged and historic architecture of the château.
However, although the exterior might appear to look like rust, the oxide produced actually protects the material’s substrate from further deterioration and constantly regenerates the protection under further weathering.
RMIG’s project manager, Sylvain Dandois, explained: “The use of tasteful contemporary design alongside the château’s traditional architecture reflects the building’s new use as a multi media library for film, visual arts, books and documents. The selection of the material, which quickly weathers to provide an aged patina also adds further character to the historic building as well as providing a practical and elegant solar shading solution.”
RMIG has 13 offices in 11 countries and provides precision engineered perforated solutions across the globe to meet the needs of a range of business sectors and industry groups.
