STC Rated Wall Assemblies

Below please find STC rated wall assemblies based on our acoustic lab tests and INSUL models. Lab tests are performed at NVLAP-certified laboratories in accordance with ASTM E90 and ASTM E492.

If you don’t see the STC Rated Wall Assembly you need below, contact one of our acoustical engineers with the desired Assembly and Target STC Rating. The below Wall Assemblies are acceptable for use in Commercial, Residential, Hospitality and many other project types.

Keep in mind that STC Lab Test results typically score 5-10 STC points higher than Field STC Tests. This is because conditions in the field such as back-to-back outlets, poorly installed RC or Sound Membrane are not present in precise Lab Tested Assemblies.
