made of LIGNO®
Versatile interior finishings in real wood
The LIGNO® Acoustic light panels are used for sound-absorbing wall and ceiling claddings. Individual design ideas can be implemented on the basis of naturally grown wood – with a large choice of wood types and profile variations for the surface, both in the residential sector and in commercial construction. The lightweight acoustic panels, which are harmless in terms of building biology, supplement the Lignotrend range of load-bearing cross-laminated timber products by a visually and acoustically appropriate interior finishing variant. For new buildings and for renovations.
LIGNO® Acoustic elements
Versatile application areas
Acoustic cladding for wall and ceiling
LIGNO® Acoustic light panels are attached over their entire surface to a substructure directly on a wall or ceiling. In the case of ceiling mounting, suspended substructures are also possible.
Suspended individually or in groups on thin cables, the acoustic elements reduce disturbing sound reflections as a local measure – for instance above office workstations, reception desks or conference tables. The lighting can be installed ex works in the prefabricated acoustic sails.
Cut-to-size element panels are also suitable for installation in conventional grid or cassette ceiling systems or for the replacement of damaged or dirty old panels. They are simply placed loose in the existing support rail construction.
Solve individual acoustic requirements flexibly
Acoustic panel configuration options
LIGNO® Acoustic light panels are manufactured entirely from grown, domestic timber. The integrated acoustic absorbers consist of natural wood fibre and the adhesives used are also guaranteed to be low-emission. Like all Lignotrend products, they also bear the natureplus seal for building biology quality.
The acoustic absorber is integrated directly in the LIGNO® Acoustic light panel. With their broadband effect, the elements achieve high absorption values. Apart from that there are acoustically optimised mounting configurations – for instance for low-frequency absorption. A certain sound steering can be achieved with low-absorbing variants.
Help with planning
In the room acoustics planning, particular attention is paid to the room size, intended use and acoustic requirements. Lignotrend offers online room acoustics calculation tools for this. The effect of room-acoustics measures can thus be estimated even before conception and implementation.
Claddings in public assembly rooms must be made of flame-retardant building materials. Nevertheless, Lignotrend manufactures its acoustic panels with real wood surfaces: If a fire breaks out, fire protection agents that are harmless and remain invisible curtail the spread of the fire.
With many different types of wood and profiles, as well as the possibility to choose the surface treatment, LIGNO® Acoustic light panels offer a broad spectrum for aesthetic interior architecture that in no way looks rustic. An attractive real wood pattern is achieved with the slat profiles.
LIGNO® Acoustic light panels are easy to process. The large format with a width of 625 mm and a length of 2,940 mm allows fast installation speeds. Individual lengths up to 8,000 mm are possible on request. The longitudinal joint in the acoustic ceiling can thus be omitted.
LIGNO® Acoustic light panels are fastened invisibly with clamps or screws. These are completely concealed in the acoustic joints and the homogeneous real wood surface thus remains intact.

Since 2006, Lignotrend products have fulfilled the particularly strict criteria for the natureplus® quality mark and thus officially belong to the most environmentally friendly and harmless building materials in Europe.
Many people are not aware that in most interiors action with regard to the room acoustics is needed. Indeed, room acoustics is important in the planning – and not only in halls or classrooms, but everywhere, even in the private dwelling environment. Quiet and good speech intelligibility increase the practical value of the room – quite apart from the positive health effect of noise reduction.

To the Room Acoustics Calculator
With the Lignotrend room acoustics calculator, reverberation or noise level reductions can be calculated and compared with the regulations of DIN 18041 - Audibility in rooms. Planners and building owners can use the online tool to make orienting calculations for the required absorber surfaces from Lignotrend products. A distinction is made according to the room groups from DIN.

Software for support
When building rooms for a large number of people according to the Venue Regulations, suspended ceilings and claddings often have to be executed with flame-retardant surfaces.
Therefore, variants were developed for the surfaces of the LIGNO Acoustic light and LIGNO Acoustic Sport acoustic panels that have been tested for flame retardancy.
Normal to flame-retardant

Important update for LIGNOTREND-dimensioning programme LTB-X v2.01
The pre-dimensioning and verification software LTB-x for slab and roof components has received an important update, which above all makes the design of storey slabs more realistic and economical.
In the new version 2.01, a more precise design of the deflection and the vibration behaviour of the elements has been implemented. The improvement of the verification procedure thus concerns the very often decisive criterion of serviceability. It is recommended to use only the latest version. Possibly a lower element height for the ceiling component made of LIGNO® is sufficient to safely solve the existing span.
The background of the update is the engineering proof that now also for the x-generation of the Lignotrend ceiling systems the visible position may be taken into account when determining the overall stiffness of the cross-section.
