The LD-SP-5708-A is an acoustical louvre system component manufactured by LOUDITY. It is a certified component of the LOUDITY™ Acoustic Louvre system and is made of lightweight, galvanized steel. The louvre is designed with a narrow cross-section profile, that reduces wind resistance when venting out air from the space. The curved blades provide directional attenuation for the sound waves traveling through, making the sound waves spread and lose intensity when passing through. The system also helps reduce air flow in and out, making it a great choice for noise control in applications such as ventilation, HVAC systems, industrial, commercial and architectural work.
