01 product description
The original school at Tonstad in Norway was built in 1965. Over 40 years later, a completely new school has been created which links the old with the new. This clever design by Filter Arkitekter offers a wealth of interesting architectural details. It generates a number of solutions to produce a unified whole because 60% of the project involves refurbishment of the old building and its swimming pool to which a new training pool and more teaching rooms have been added.
Inevitably any school, particularly in the swimming pool, corridors and areas with hard surfaces, will be very noisy. To overcome this, extensive use has been made of Troldekt acoustic ceilings which not only absorb sound but do not reflect light. One unusual feature is the random replacement of some ceiling tiles by glass ones through which is cast pleasant diffused lighting.
In the new training pool, the ceiling surfaces has been designed differently because of the extra height needed for diving, being low around the pool edges with high windows in deep recesses in the concrete walls. The acoustic performance in both pools has been further enhanced with wood strips fixed to the walls in the shape of a wave and insulated behind.
For this project, the architect wanted acoustics to be an integral part of the design solution and not a future problem. Architect Knut Brandsberg Dahl says, ‘Troldtekt was specified because we also wanted a robust and durable ceiling which will tolerate high humidity and look good.’ Importantly, the sustainable tiles complement perfectly the architect’s concept with its focus on sustainability and environmentally friendly solutions.
Troldtekt panels are made from 100% natural materials; wood from Danish forests and cement produced by Aalborg Portland, Denmark. The structure of Troldtekt panels provides a basis for excellent sound absorption, and using Troldtekt ceilings will, therefore, reduce noise and provide optimal room acoustics. Troldtekt is available in a high number of combinations that vary according to surface structure, edge, installation system, colour, dimension and thickness.
