What are they?

The Basotect® acoustic panel SLÄT is a fireproof sound absorber, with square profile, measuring 600 x 600mm x 40mm of thickness, specially designed to solve the problems of high reverberation in public spaces such as: restaurants, pubs, classrooms, offices, libraries, etc.

It is made by fireproof acoustic foam Basotect® (melamine resin foam), which has a high sound absorption performance, better durability and the best fire-resistance: Class 1.

® Registered trademark of BASF SE


This Basotect acoustic absorber has a Class 1 (BS 476/7) fire resistance (fireproof).
It is a panel suitable for be installed in public establishments.

What is the application used for?

SLÄT, is a self-installable acoustic solution, developed to solve high reverberation problems that usually exist in public places: bars, restaurants, classrooms, dining rooms, offices, meeting rooms, libraries, etc.

What is their format?

  • Panels of: 600mm x 600mm x 40mm thickness.
  • Colour: Light grey or White
  • Sold in units: area coverage = 0.36 m2
  • Normal packaging: According to units (120g / ut.)

Finishing options

On request, Slät acoustic panel can be coated with a textile cover, in multiple colors, which enhances their acoustic performance and gives to the panel a finished with better aesthetic quality, allowing their adaptation to the architectural environment in which it is located.

In the "Finishes" tab you can know the different finishes options and main colors available.

How is it installed?

It is self-installable; Slät acoustic panel can be fixed directly, using our Skac Adhesive, to the ceiling and walls*; It weights only 150g per panel, so does not require any specific specialist for the installation; It can be installed by ourselves.

* Walls: It is recommended that the panels not be accessible to the people, to prevent them from being damaged.

How much do I need?

For a simple and effective solution, we have prepared a mini-guide that will help you to determine easily the panels that you need for your particular case, based on the m2 of flooring surface, room height and the level of comfort to be obtained.

First, we have to choose from three levels of comfort:

Live Grade with fewer sound absorbers (less expensive), we get a more lively atmosphere, recommended for bars, cafes, canteens, sports halls, arcades, etc.
Medium Standard grade; a balanced ratio between the quantity and grade of sound absorption; defined to achieve an adequate level of sound comfort for holding conversations without raising the voice in: restaurants, classrooms, and offices.
Dark Higher degree of sound absorption, to achieve the lowest reverberation level; it is recommended for large offices, libraries, waiting rooms, etc.


Then, based on the comfort level selected above, we will set the % of room surface that must be covered with acoustic panels.

Height / GradeLiveMediumDark
up to 3m 35 % 50 % 65 %
up to 4m 45 % 60 % 75 %
up to 5m 60 % 70 % 80 %


Finally, with some simple math calculations, we determine the necessary units of Slät panels to be installed.

Area to be covered = m2 of room x % of coverage.

The necessary units of Slät panels will be the result of dividing the area to be covered by 0.36m2 (are occupied by one Slät panel).

Let's see a practical example:

Restaurant with a total flooring surface of 200m2, which has 120m2 for dinning zone; the total height is 3m in dinning zone.
For this kind of application, we want to get a 'medium' comfort grade; that it's coverage of 50% for spaces up to 3m of height.
Area to be covered will be = 120m2 x 50% = 60m2.
Necessary units of Slät panels = 60m2 / 0.36m2 = 168 units.

The quantity calculations indicated above is a simplified selection guide. If you have any question or you want that our acousticians make you a customized proposal, please contact-us!.

Tell us what kind of place this is, size / height and we will make an appropriate proposal for the supply of acoustic panels.

The acoustic panel SLÄT can be coated with different finishes:

  • Textile: applying a velvety cover that enhances the absorption performance of the panel.
  • Painted: applying a specific paint by a exclusively technique developed for don't plugging the pores of the foam to avoid the usual performance losses with traditional painting techniques.
