Selected for their weather, thermal and security performance, TECHNAL aluminium curtain walling, windows and doors was specified and installed at Ysgol Penyfford - a £7 million-pound primary school located in the Flintshire villlage of Penyfford in Wales. This project has been constructed to BREEAM Excellent standards.
The two-storey school features two striking pitched curtain walling screens on the front and back elevations. These are designed specifically to open up and brighten classroom spaces, bringing as much natural light into the school as possible. Interfacing with dark grey and timber effect weatherboarding and echoing the line of the roof, the aluminium systems are finished in a dark great polyester powder coating.
Working with this contemporary architectural design, Technal Elegance 52 Curtain Walling suited the project exactly thanks to its narrow sightlines, which create a modern appearance. In addition, the curtain walling was selected for its unique manufacturing
capability, which allowed Westmore Architectural to match the pitch of the roof. The curtain walling screens to the project’s front elevation were fabricated with the CNC using welded sleeves for each apex.
TECHNAL also worked closely with the architectural practice to ensure correct product specification, including two key requirements: thermal efficiency and PAS 24 security.
Mike Molyneux, Project Consultant for Technal, highlighted: “The most crucial element to this project was getting the curtain walling screens to match the requirements for the pitched roof and setting out. Technal was selected for its ability to meet the necessary weather performance, and thermal and security requirements.”
Elegance 52 curtain walling uses an aluminium substructure width of 52mm, allowing a slim sight line while also providing the necessary strength and inertia requirements. It delivers high quality acoustic performance as well as the aesthetic appearance to
suit different property types. Offering multiple opening configurations, the Technal Dualframe 75 Si window range has been installed in ribbon configuration to
all elevations. Exceptionally energy efficient, Dualframe 75 Si system can achieve specified U-values down to 0.9W/m2K. As well as achieving thermal performance, the Dualframe 75 Si suite also attains superior weather performance for water tightness, air
permeability and wind resistance.
The STII Commercial Doors, which were installed on the entrances and fire escape, have undergone an extensive testing regime to achieve the required PAS 24 security. The doors also meet the necessary requirements for thermal insulation, achieving a Uvalue of 1.8W/m2k for doors without midrails and 1.9W/m2k for doors with midrails.
