STC 50 large double doors are used in applications where you need noise control in a building and need access to move large objects in and out of the facility.  Industrial, Military and Stage doors typically require this type of door.  Many times, roll up or garage type doors are utilized for these applications.  These types of doors are very poor at keeping noise out and inherently hard to acoustically seal.  This is where large sound rated flush mounted swing doors are a perfect fit for the application.

Sound Transmission Class is a measure of sound transmission loss through a material or assembly, showing its effectiveness in blocking noise.

Large STC 50 Doors will be custom build for sound control applications. These custom made doors that meet the STC 50 rating will have specific designs, construction materials, and features to reduce sound transmission.

Door Construction: Doors constructed with heavy-duty materials like heavy gage steel. This provides superior sound blocking properties and will withstand the demands of harsh environments.

Door Seals: STC 50 doors will be provided with multiple acoustic seals to create an airtight and soundproof seal. These seals help prevent sound leakage around the door perimeter.

Heavy Duty Hardware: Heavy-duty hinges, handles, and closing mechanisms designed for durability and security. These components will be capable of withstanding the demands of your application while maintaining the door’s acoustic properties.

Certification and Testing: The Sound Rated Door’s design will tested and certified by independent acoustic testing laboratories to meet the desired STC rating. This ensures that the doors have undergone acoustical testing to validate their Sound Transmission Class rating.
