Client: National Museum of Wales
Architect: Alwyn Jones Architects
Contractor: Metal Solutions (SW) Limited
Type of works: supply of VITRAL's A74 glazing system.

The National Museum of Wales in Cardiff is undergoing redevelopment of the upper west wing, which includes the replacement of and installation of new roofglazing. VITRAL had already been used in 2007 when the East Wing was refurbished, so with complete confidence in Vitral and with its unrivalled performance, VITRAL was specified again for the west wing development, this time with the VITRAL A74 system.

The glazing solution is specific to museums and galleries; it prevents any ultraviolet light being transmitted through the glass, so ensuring that paintings and other important artifacts aren’t damaged in any way by UV light. This 0% UV light transmission, coupled with the low U-values provided by VITRAL’s A74 roof glazing system mean that The National Museum of Wales in Cardiff has the best performing rooflight solution that will ensure the property and artifacts are protected from UV light deterioration and that as much energy as possible is retained within the building.

VITRAL’s A74 roof glazing system achieves a typical U-value of 1.6 W/m²K, coupled with its high performing air tightness of Class 4 at 600 Pa, the A74 system is being specified for buildings that need the best performance possible, such as buildings being design with PassivHaus principles.
