More about this product

Lamellow+ is Gustaf's new combination of wood and felt wall covering, with all the qualities required for public environments.

Consisting of real wood veneer and reinforced fiber backing that is finished with a felt, the panels have received various fire, air emission, sound absorption, and other common certifications in the building industry. The core of Lamellow+ ribs consists of reinforced fiber gypsum, Anthracite or light grey. The felt is available in three colours: Anthracite, Dark Grey and Wool Grey.

Depending on the colour of the acoustic felt backing, the overall impression of the veneer and the finished surface will vary. As a result, there are many possible designs and colour combinations. Gustaf's Lamellow+ panels are produced as modules ready to be installed directly on the walls or in the ceiling.

By using Lamellow+ framing profiles and additional felt strips, you will always have a perfect framing around your panel. The framing profile can be used on all sides of the panel edges and gives the installation a solid wood feel. Gustafs' products have been optimizing room sound quality for decades, from smaller offices to world-famous concert halls.


  • Fire
    The high-density nonflammable core and the surface veneer’s strongly bound adhesion to the fiber gypsum rib give the ribs the classification 'Reaction to fire B-s1,d0'
  • Acoustics
    The linear system automatically gives a relatively large open area of 24% which warrants for a good sound absorption over a wide band of frequencies. The three-dimensional shape will also act as a sound diffuser.

Suspended Ceiling, plus 200 mm air void αw 0,90-A NRC 0,85
Wall/Ceiling, direct installation αw 0,30-D NRC 0,55
  • Integrated system
    Capax is a unique aluminum profile installation system that provides a concealed, reliable, quick and cost-saving installation. The Quick-Up assembly system is a user-friendly aluminum grid offering installation reliability and a perfect visual result. No tools are needed to assemble the interlocking components. A demountable version is available, ideal when access to the ancillary systems is required.
  • 100% straight aligned
    Gustafs Linear Ribs with a Fibre Reinforced Gypsum Core, in combination with Capax installation system, guarantees real dimension stability, resulting in 100% straight aligned timber panels over their full lifetime, regardless humidity and temperature changes.
  • Sustainability
    Using a fiber gypsum core naturally results in extremely low emissions and a very high rate of recycled content. The panels are produced with renewable power sources only.
