The double skin polycarbonate system used in the refurbishment of the Sports Hall in Wissous is innovative for a number of reasons.
Firstly, this polycarbonate system is made of 2 clip panels of 40 mm each, separated with the 40 mm space which creates a space filled with air. This unique structure allows for a record thermal insulation for polycarbonate: Ug = 0.5 W/m².K which is more performant than triple glazing.
The excellent performance of this polycarbonate system allows for designing complex facades which allow for high natural light penetration. Natural light is no longer limited with partial polycarbonate glazing.
Furthermore, joining the 2 skins systems results in an increased distance between supports, up to 3 m. From the aesthetic point of view it allows for limiting the number of supports which can be easily visible and gives the facade its ‘lightness’.
Finally, as polycarbonate is a very light material, its weakness for large and complex facades is often the sound insulation. However, with the double skin polycarbonate system used in this project, sound insulation is considerably improved, resulting in 28 dB acoustic co-efficiency. This is the result of the unique structure of the two polycarbonate layers, 40 mm each. This co-efficiency can be even increased up to 34 dB by adding a solid polycarbonate sheet between the two, 40 mm thick panels.
In this renovation project of Wissous sport Hall, blue double skin polycarbonate system was used to replace a simple polycarbonate cladding to cover a complete façade. The particular method of installation of this system makes the metal structure behind almost invisible and lets the natural light penetrate the inside of the building. Due to its excellent technical parameters, double skin polycarbonate system was chosen as it conforms to the European norms: high thermal and acoustic insulation.
