STC Rated Doors

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.

The Test Report for STC 41 doors is ATI No. 94453.01C2, 94453.01C5, & 94453.01D5. For STC 42 it is 94453.01C2.  The Test Reports for STC 45 is ATI No. 94453.01D1, 94453.01D10, & A9041.01B. For STC 46 it is ATI No.  94453.01D2, 94453.01D3, & 94453.01D6.

Lynden Door has a growing list of STC doors, including:
