How is it installed?

It is self-installable, with no need for work; the Slät XL acoustic panel is fastened to walls and ceilings* with our Skac Adhesive. With a weight of only 300 g per panel, no special instructions are required, and it is very easy to install.

* Walls: it is advisable for the panels not to be accessible to people, to prevent damage/injury.

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 0.72m2 (area occupied by one Slät XL panel).

Let's see an 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 XL panels = 60m2 / 0.72m2 = 84 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.

SKAC - Color spin The acoustic panels are painted with flame retardant paint, through an exclusive technique developed to not alter the acoustic performance of the panel, thus avoiding the usual loss of absorption capacity that occurs with traditional painting techniques.

Painting specifications - Skum Acoustics

  • · Flame retardant paint: Class A, s2-d0.
  • · Finish: satin.
  • · Maintains the acoustic performance.
  • · Available to choose color according to RAL chart.
