Troldtekt: Quiet transformation for iconic Boys’ School

  • 20 May 2024

Architects Hawkins Brown have completed a transformative redevelopment at the Central Foundation Boys’ School, the 150-year-old top performing comprehensive school in central London – Troldtekt acoustic panels feature there…

The vision was to rationalise and consolidate the school’s several buildings into a cohesive design to allow more efficient use of the campus.

Works included providing a new, purpose-built science building equipped with state-of-the-art facilities along with a new three-court, multi-use sports hall with changing facilities. The tight nature of the site meant that the sports hall was sunken under the courtyard with rooflights bringing in natural light. It has been designed to comply with Sport England guidance, providing the school with a flexible multi-purpose space that can be used for out-of-hours community activity. 


To help combat the problems of poor acoustics and sound reverberation in the sports hall, music and drama rooms, Hawkins Brown specified Troldtekt acoustic panels across all the ceilings. Panels were chosen in both grey and natural finishes to provide a discreet look whilst complementing the interior design. Troldtekt solutions excel at providing acoustic comfort with a visually attractive, aesthetic tactile surface along with high durability and low-cost lifecycle performance.

Benefits of Troldtekt acoustic panels

Troldtekt acoustic panels are available in a variety of different structures and colours, combining superior sound absorption with an award-winning design. The Troldtekt range has a minimum expected life cycle of 50 years coupled with excellent resistance to humidity and tested to meet ball impact standards.

The range is available in various sizes and structures, from extreme fine to fine. They can be supplied as natural wood, and in the carbon-reduced FUTURECEM™ finished in almost any RAL or NCS colour. 

Depending on the panel specified, reaction to fire is classed in accordance with EN 13501 as B-s1,d0 or A2-s1,d0 respectively. Cradle to Cradle Certified® at Gold level, Troldtekt wood wool acoustic panels are manufactured using wood from certified forests (PEFC and FSC®C115450) and can contribute positively to a building’s BREEAM, WELL or LEED points.
