Kindergarden and school Bellmund

Cleverly renovated premises 

Never before has the application of roof formwork with finished soffit on existing or newly erected rafter roofs been so uncomplicated! The histori-cal roof truss of the Bellmund kindergarden could be retained, the cross laminated timber elements were simply laid as large-area boards on the top of the rafter layer instead of conventional roof formwork. On the inside of the roof, they show their ready-for-use soffit made of knotless silver fir.

Configuration overview

Components used

  • LIGNO Acoustic light  |  Ceiling cladding 

    LIGNO Akustik light 3S_62_a50g_625-12-4_WTL_gb_buv
    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

    _WTL Silver fir knotless, patterned 

    Profile


    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.

    Profile 

    _625-12-4 Slat profile 

    Structure


    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.

    Structure

    _gb Brushed

    Treatment


    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.

    Treatment

    _buv UV-protection stain 

    Room acoustics


    If the soffit of the element is to have a good sound-absorbing effect, the penultimate layer is configured as absorber _a50g. Otherwise, this layer is configured as a solid wood layer _a0.

    Room acoustics

    _a50g 50 % Absorber
