Concentrate totally on your work. WINEA MATRIX will see to the quiet you need – e.g. as a room-divider with effective sound-sensitive fronts. In order to reduce unwanted noisy backgrounds to a minimum, e.g. in open-plan offices, the programme for unit single elements of up to 4 FH (file heights) not only offers perforated shutter fronts, but also micro-perforated fronts for swing and sliding door elements. Up to 300,000 micro holes per square metre are the guarantee for the very best in sound absorbance.
