Acoustic louvres

Acoustic air louvres used for air intake or exhaust, resulting in a reduction in the initial noise level. Manufactured in galvanised steel sheet with bird mesh on the rear. The louvres incorporate rock mineral wool insulation protected by perforated galvanised sheet metal on the underside. They prevent rain from entering from the outside. All materials used are non-combustible. The mineral wool in the cells is classified as A2 S1 DO, according to standard UNE-EN 13501:2002.
