Wooden roof panel
dampens noise level

Industrial noise reduced by 6 dB 

In dieser teils lärmintensiven Produktionshalle ist eine effektive Dämpfung des Lärmpegels essentiell, was hier durch die Verwendung von LIGNO® Akustik Q klassik mit integriertem Absorber erreicht wird.
Mit der Verwendung akustisch wirksamer Dachscheiben von Lignotrend bietet sich in der BST-Halle ein Arbeitsumfeld, das mit höherer Ruhequalität das konzentrierte Arbeiten und damit auch die Arbeitsqualität und Arbeitssicherheit fördert.
Für die Sicherstellung einer angenehmen Raumakustik wurden in der Produktionshalle Lignotrend-Dachbauteile verbaut, welche durch einen integrierten Absorber statische und raumakustische Aufgaben zugleich übernehmen.

The client of this first commercial project carried out with LIGNO® Acoustic is a specialist in the production of airbag fabrics. The company operates production sites around the world, some of which are noisy. An essential requirement is therefore the effective attenuation of noise levels - as was the case with the new construction of this hall for the expansion of the site in Murg.  

Configuration overview

Components used

  • LIGNO® Acoustic Q classic  |  Roof component

    Product code: LIGNO® Acoustic Q classic_Q3_150-210_rg0_s0_k50l_p0_al40g_625-95-30_WTL_gb_b0
    Installation top

    Whether the element is open or closed at the top is determined by the area of application. If, for example, the element is to be filled with fill on site as a storey ceiling or roof terrace (LIGNO® Rippe Q3-x), its cavities are open at the top (feature _r0). To guide pipes at the top of the element, a cross grid (_r25, _r50) can be added to some superstructures. For roof superstructures, there is usually a flat closed finish _rg0 (LIGNO® Block Q-x, LIGNO Block Q3-x or corresponding versions of LIGNO® Acoustic classic).

    _rg0 Closed, without crossgrid


    The height of the load-bearing webs of the element is variable and determined according to static requirements from load and span. Within the framework of this configurator, the selection is limited to four height ranges. A more precise definition is made later during pre-dimensioning or verification with the LTB-x calculation programme. Bulk volume and/or necessary space for installations can also be decisive for the height.

    Fire resistance


    If fire protection is required, an additional layer is added below the web area (for elements with strip profiles _z26, _z53, _z80, for elements with board profiles Akustik klassik _k50g). Their height determines the fire resistance duration of the cross-section from 30 to 90 minutes. The fire resistance must be statically verified. If there are no requirements, the standard versions _z0 or _k50l are to be selected.

    Panel designs with slat profiles and additional layer can be configured with an additional cavity (_p26, _p53) below the additional layer for installation guides, fixtures or to improve sound absorption. Cables laid there then do not penetrate the fire-protection layer. If required, the cavity is filled with insulating material (_p26mw, _p26ha) to improve acoustic absorption. If no cavity is necessary, the characteristic _p0 is selected.

    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.

    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.

    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 knotless, patterned


    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.


    _b0 Untreated


    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.
