Sound-attenuating external louvre
Weather and noise protection at reduced depth

Sound-attenuating external louvres of the type NL are designed for use in ventilation and air conditioning systems. They offer good protection against driving rain and prevent birds and other small animals from entering into the system; these gratings cannot offer a completely watertight barrier, however. Sound-attenuating external louvres of the type NL are employed primarily when weather and noise protection are required in conjunction with louvres of reduced depth. Available as a double louvres, type NLH, for increased acoustic requirements, or as a blind louvres, type NLD, for visual integration. Available as steel or aluminium grating in diverse design variants.
