Stc Rated Doors And Frames
The stc rating is calculated in accordance with astm e413 it s a single number rating for interior building partitions that are subjected to mid to high frequency noises.
Stc rated doors and frames. Additionally cam lift hinges and an aluminum threshold are included with high stc rated assemblies. Soundproof steel doors are available 1 3 4 thick from stc 33 to stc 53. Founded in 1846 by mesker brothers in st. The maximum rating would be 40 for the b series steel stiffened door when used with the approved gasket.
In some cases the rating applies only to the door panel as it has been tested without the door frame assembly. A critical factor to understand when specifying acoustic doors and frames is the sound transmission class or stc rating. Louis mesker manufactured storefront facades out of sheet metal and eventually engineers developed the world s first hollow. Steelcraft have tested different types of doors and frame assemblies using zero international gasket seals for the various stc ratings.
A door that has been sound rated usually means the door panel jambs frames and seals have been tested in a lab for sound transmission loss tl and earned an stc rating. There are quite a few complicated steps in the installation process that are critical to the performance of the door. Tests are in accordance to astm e90 and astm e413. Heavy duty sound transmission control steel door and frame systems.
