Indoor swimming pool "de ijsselslag"

Rest pool

The representative indoor pool has different swimming areas and is constructed as a prefabricated reinforced concrete building. The facade is clad with copper-coloured aluminium panels above a circumferential window band. Inside, the “folded” roof construction made of steel girders with its sloping roof surfaces can be seen. Genuine timber panels of light silver fir on the walls and ceiling radiate comfort and fit perfectly with the modern architectural language of the building.

    Wood type 


    Various wood species are available for the visible layer. For quality reasons, individual wood species cannot be configured for all profiles; for technical reasons, surface treatments are excluded for some wood species.

    Wood type 

    _WTE Silver fir, economy 



    The visible layer is profiled with joints. The code for profiling indicates in millimetres: Element width, strip width (rounded, from/to if applicable) and joint width (rounded) as well as a letter identification for variants, e.g. with chamfered strip edges or with additional height gradation.


    Note: Some profiles indirectly cause exclusions for other configuration options.


    _625-23-8 Slat profile 



    The face is subjected to a brushing _gb as standard, which produces a stronger or weaker structure depending on the type of wood and makes the surface less sensitive to scratches.  Alternatively, a smooth sanding _gs can be carried out, or on request a bandsaw cut _grimitated.


    _gb Brushed 



    Depending on the type of wood, the optional application of a surface treatment is possible ex works. Individual colour finishes are always sampled for coordination. For elements in individual lengths, colour treatment is limited to max. 5 m length.
