Acoustic Louvres - AL Series AL acoustic louvres are specialist external louvres, designed primarily for areas like plant rooms or inner city car parks, where noise generated by machinery or vehicles cannot be allowed to leak into the surrounding area. Using a twin part aluminium blade infilled with mineral wool, Monodraught acoustic louvres offer a high resistance to rain ingress, whilst also having sufficient depth to provide useful levels of sound attenuation throughout a wide range of frequencies. Available in 150 mm, 300 mm and 600 mm deep variants. Download Product Card for specifications and selection criteria.
