San Mamés Stadium

After four years of construction work, Athletic de Bilbao fans were able to enjoy their new stadium on September 2013, a venue with 53,000 seats, which shares the name of its legendary predecessor, located few metres away. The building’s project team sought to achieve total air tightness for the roof, while maintaining highly permeable façades and perfect acoustics.

URSA is very much present in this new facility: 8,000 square metres of 80 mm thick URSA TERRA Vento and 13,000 square metres of 75 mm thick URSA GLASSWOOL have been used to insulate ceilings. URSA GLASSWOOL was also used in 50 mm thick sheets to cover nearly 14,000 square metres of interior partition walls.

URSA TERRA Vento is traditionally used to insulate ventilated façades. Each panel is finished with an outer veil that protects the inside wool layer from weather conditions. However, more and more contractors are using these versatile panels to achieve top insulation indoors, in false ceilings or partitions, acting as a base for mineral wool.

URSA GLASSWOOL is a natural, high-quality, cost-effective, extraordinary fire resistant mineral wool with outstanding thermal and acoustic insulation properties; the ideal choice for the insulation of interior partitions walls.

The engineering consultant IDOM is responsible for this project that has changed Bilbao’s physiognomy without altering its environment. IDOM is working towards achieving top ratings in LEED certification for the new San Mamés Barria. Company representatives believe the process will be completed towards the end of 2014, certifying this stadium as a pioneer in including sustainability in the whole design and construction process: from first stages to materials used.
