The new Type ACDSV Smoke Vent is specifically designed to provide fire and smoke protection for applications where exterior noise intrusion is undesirable, such as in auditoriums, concert halls and theaters. Carries an OITC-46 sound rating to guard against low-frequency outdoor sounds such as traffic and airplane noises and an STC 50 sound rating. Features mineral wool insulation and high-density sound mat material within the unit’s covers and curb to better inhibit sound transmission.
