Fassa Bortolo, the forefront Italian render manufacturer, has recently provided its expertise to the completion of Project Oak, the new four-storey global headquarters for Spirax Sarco Engineering in Cheltenham.

Tasked with augmenting the existing listed building, Charlton House, which has served as the headquarters for over eight decades, Fassa Bortolo undertook the construction of a curved extension to complement the historic structure. This innovative addition boasts 180 workstations, a gym, and an auditorium, embodying modern functionality within a heritage context.

For the external rendering, Fassa Bortolo deployed its state-of-the-art Fassatherm system, specifically the Fassatherm Frame Plus system, certified by Kiwa BDA. This system, renowned for its efficiency, utilises A 96 adhesive along with mineral wool insulation, ensuring both thermal performance and structural integrity.

The finishing coat, was the application of RX 561 acrylic-siloxane top coat. This not only ensures a flawless finish, but also provides essential protection against environmental elements.

Designed by Roberts Limbrick, the project’s architectural finesse is paralleled by its commitment to sustainability, achieving an esteemed BREEAM ‘Outstanding’ accreditation, a testament to its positioning among the top 0.5% of sustainable new builds worldwide.

In alignment with the project’s ethos of efficiency and sustainability, Fassa Bortolo’s involvement exemplified their commitment to delivering bespoke solutions that seamlessly integrate cutting-edge technology with architectural brilliance.
