The higher the rating the better the sound control. Laminated glass laminated glass is also available for added strength enhanced security and sound control. Assemblies have been designed to accept readily available heavy weight builders hardware. Soundproof steel doors are available 1 3 4 thick from stc 33 to stc 53.

Laboratory testing is used to measure the resistance of partitions such as walls windows or entry doors to the passage of sound. Sound reducing glass this glass helps reduce the volume of outside noise. When specifying acoustical doors one often overlooked concern is the hardware. Stc ratings are used for windows doors walls and most building materials.
