Sound Transmission Class (STC) Rated Doors are regulated and administered in a manner similar to fire doors. That is, door core manufacturers are required to submit cores for a test and once they have passed that test, may license fabricators like Lynden Door to produce acoustical doors under manufacturer test auspices.
Doors are available that meet STC 35 E90-04 - Operable; STC 38 E90-04 - Operable; STC 40 ASTM E90-04 - Operable; STC 41 ASTM E90-04 - Operable; STC 42 ASTM E90-04 - Operable; STC 45 ASTM E90-04 - Operable; and STC 46 ASTM E90-04 - Operable.
The Test Reports for STC 41 doors are ATI No. 94453.01C2, 94453.01C5, & 94453.01D5. For STC 42 it is 94453.01C2. The Test Reports for STC 45 are ATI No. 94453.01D1, 94453.01D10, & A9041.01B. For STC 46 it is ATI No. 94453.01D2, 94453.01D3, & 94453.01D6.
