Stc Door Hardware

Because acoustical doors are constructed differently than traditional hollow metal doors certain considerations must be made when selecting hardware for them.

Stc door hardware.

Heavy duty sound transmission control steel door and frame systems take control of your environment and reduce unwanted noise with acoustical stc rated doors and frames. 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. Self contained high security door in box kit. The best performance rating on the operable test is a zero drop in the assembly s stc rating.

Extended flanges on both sides measure 42. Acoustical performance of building products components and systems is an important consideration for engineers specifiers and building owners. When specifying acoustical doors one often overlooked concern is the hardware. Sound transmission class stc 16 gauge cr steel meeting astm a366 specification internal sound retardant core and isolator perimeter edge construction.

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. No lead or asbestos in core us patent no. Cv200 series non thermal t200 series thermal n200 series non thermal t237 series thermal hung. A critical factor to understand when specifying acoustic doors and frames is the sound transmission class or stc rating.

We do not sell to the general public only security professionals. It can never achieve a stc 50. 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. The acoustic automatic door bottom is specifically designed for acoustic openings.

Sound transmission class stc ratings solve that problem by giving a single value to acoustical performance for a door. 2820 pass thru series non thermal 500 series non thermal thermal acoustic. Cv200 stc series non thermal t200 stc series thermal. 52 series non thermal thermal sliding.

Our door in a box comes in one package complete with. Body measures 562 w x 1 375 h. Stc47 50 52 or 55 hmd door frame hardware specified locking. Operable stc ratings are always equal to or lower than the sealed in place ratings.

Lockmasters self contained high security doors are built to your exact specifications.
