Description

Overview
The 448/150 is an acoustic ventilation louvre with a soundproofing Rw of 11 dB. Acoustic ventilation louvres are used in various applications to allow intensive ventilation combined with soundproofing. In residential buildings, for example, acoustic louvres are integrated into façades exposed to noise. Acoustic louvres are also used in industrial construction to dampen noise from technical installations. The louvres are made of aluminium profiles and available in all RAL colours or anodised. The blades are fitted with acoustic soundproofing material (non-combustible mineral wool).
