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. A critical factor to understand when specifying acoustic doors and frames is the sound transmission class or stc rating.

Our door in a box comes in one package complete with. 5 417 029 fully reinforced to support mortise and surface mounted hardware concealed electric power transfer ept and. 52 series non thermal thermal sliding. Extended flanges on both sides measure 42.

Body measures 562 w x 1 375 h. Self contained high security door in box kit. Sound transmission class stc ratings solve that problem by giving a single value to acoustical performance for a door. Cv200 series non thermal t200 series thermal n200 series non thermal t237 series thermal hung.

It can never achieve a stc 50. Independent testing has shown that the stc series automatic door bottom has sealed in place type performance and has a smoother action positive seal mechanism. Stc is determined by a weighted average of tl values taken over 16 frequencies which are fitted to a curve in a method defined by the astm e413 classification standard for rating sound insulation.
