SOUND ABSORPTION
Sound absorption has been measured in accordance with ISO 354. The sound
absorption properties of items such as islands or baffles are quantified by the
equivalent sound absorption area expressed as m2 per item. This is the area of a
100% absorbing surface which would absorb the same amount of sound as the
item in question.

CLEANING

Hygienic Baffle:
The surface can be vacuum cleaned with a soft brush attachment.
The surface can also be cleaned once a week using a sponge or cloth and warm water
(max. 40°C) with a slightly alkaline detergent (max. pH 10) without alcohol, ammonia
or chlorine.
Cleaning with a damp sponge or cloth may render the surface slightly shinier and we
therefore recommend cleaning the whole surface evenly for best results.
The surface can be foam cleaned once a week. Spray foam onto the surface at low
pressure. Let it work for 5 minutes and then sluice or wipe clean.
Soap solutions should be 1:100.
The surface can be high pressure cleaned once a week. Max pressure should be
65 bar at 1 metre distance, and water should be spread at a 30º angle.
Soap solutions should be 1:100.
