Stc ratings for concrete walls.

Due to increased mass poured concrete and concrete blocks typically achieve higher stc values in the mid stc 40s to the mid stc 50s than equally thick framed walls. 1 contains procedures for determining stc values of. Fire resistance ratings with multi layer designs ul u415 oscillation tested to 1 million cycles to ensure structural performance feature panels with water resistant facings and or mold resistant paper and a water resistant core to help minimize the risk of moisture damage for more information see the following brochures. There are numerous other issues that need to be addressed to get a more accurate.

The green line is the performance of the wall. A wide variety of stc ratings is available with concrete masonry construction depending on wall weight wall construction and finishes. When the mass of a barrier is doubled the isolation quality or stc rating increases by approximately 5 db which is clearly noticeable. Stc 14 1w equation 1 is applicable to uncoated fine or medium textured concrete masonry and to coated coarse textured concrete masonry.

Mass is commonly added to existing walls by adding additional layers of gypsum. All too often this plenums and suspended ceilings unbaffled ducts window to window outdoors common heating units transoms and air grilles unblocked joist spaces uncaulked wall perimeters ducts piping and fixtures masonry joints. In the absence of test data standard calculation methods exist which tend to be conservative. The estimate could easily be off by as much as 4 db.

Refer to manufacturer specifications stc what is heard. Tested systems achieve up to 58 stc have achieved up to 4 hr. Because coarse textured units may allow airborne sound to enter the wall they require a surface treatment to seal at least one side of the wall. However the additional weight added complexity of construction and poor thermal insulation tend to limit masonry wall partitions as a viable sound isolation solution in many building construction projects.

The stc rating of a cmu wall can be estimated based on its weight using the following formula. Adding green glue to boths side of a wall. The standard requires a minimum laboratory stc rating of 50 for party walls and floor ceilings. Standard method for determining sound transmission ratings for masonry walls tms 0302 ref.

Assembly or a double stud wall can yield an stc as high as 63 or more other materials such as mass loaded vinyl mlv soundproof gypsum wallboard or liquid applied dampening compound may also improve stc ratings. The magenta line in that graph is the standard reference stc contour.
