The performance of an acoustic product is measured based on Sound Transmission Class (STC) rating. A higher STC rating indicates a greater reduction in noise transmission. 

Acoustic Steel Doors & Frames are available in STC 33 to STC 53 at a thickness of 1¾ʺ and available in higher ratings in greater thicknesses. Custom-engineered solutions are also available for ratings higher than STC 64. 

Doors are provided complete with acoustic steel frames, and perimeter and bottom seals. All Acoustic Steel Doors & Frames are constructed to accept heavy-weight builder’s hardware and are accessible with factory pre-installed acoustic glazing.

All Acoustic product assemblies comply with the latest ASTM-90 and E-413 standards.
