Partition Isolation Theory:
Preventing airborne noise and structure-borne vibration from passing through
walls into adjacent spaces is not only a comfort concern; it has become mandatory
with new, stricter building codes. Noise prevention is achieved by two methods.
The first is to decouple the partition from the structure. This prevents structure-borne
noise from flanking through the wall into the spaces above and/or below the
treated area. The other method is to increase the STC value of the partition
itself. This reduces direct noise transmission between two spaces, as does
a wall between a mechanical room and an office space. It is important to note
that both methods may need to be employed to satisfy noise control requirements.
Kinetics Noise Control partition noise treatment products are key components
that ensure partitions perform as designed.
Application:
Kinetics Noise Control’s Model Wallmat resilient partition isolation pad
offers designers a quick and easy solution for resiliently decoupling a sound-rated
partition from non-isolated structure. Flanking of sound through a floor/ceiling
assembly can reduce STC (airborne noise) or IIC (impact noise) ratings 10
points or more versus non-flanked sound control construction. Frequently used
in conjunction with other Kinetics sound isolation products, Model Wallmat
creates a resilient break to stop sound or vibration from flanking around
a sound rated assembly. Neoprene bushing assemblies (Model KAI) used at each
anchor point through the top and bottom plates of the stud wall ensure effective
isolation. Apply Model Wallmat continuously along the bottom and top plates
of a stud wall wherever acoustical isolation is required to maintain a fully
effective sound rated assembly. For isolating masonry walls, see our higher
load capacity Model NAFP-10.
Benefits:
- Easy to install pre-cut strips
- Field cut to length with a utility knife
- Continuous resilient support of the partition
- Engineered for a wide range of studwall loads
- Use Model KAI isolation bushing assemblies
for 100% resilient separation
- Use for both top and bottom plate installation
- Use Wallmat and the KAI bushing in UL
system no. HW-D-0031, single steel stud, and UL
system no. HW-D-0447, double steel stud, for sound control in dynamic
head-of-wall joint systems
