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.

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.
