`Acoustic Engineering Of LIfeSPACETq
`l
`
`STC and CAC ratings measure individual building components separately. Privacy Index is a system
`performance measurement of the entire building environment.
`
`LifeSPACETM Walls have been acoustically engineered to take into consideration wall system joints and seals at
`ceilings, floors and base building connections, etc.
`
`The following is a list of some of the materials and acoustical engineering included in the LifeSPACETM Wall
`system.
`
`Gypsum Board
`
`The properties of the gypsum board used by
`SMED are specially formulated in a patented
`assembly to provide optimum speech privacy in
`
`the sealed wall panel and assembly.
`
`Insulation
`
`
`
`1” (25mm) optimum batt fiberglass insulation in the panel with
`additional insulation added to the top and base cavities.

`
`
`Split Center Beam
`
`Top Track
`
`Minimizes direct transmission through the panel.
`
`
`Split closed cell foam is used for maximum density and compressability.
`
`Wall Start
`
`insulation used in cavity of connection.
`
`Split closed cell foam (same as with top track) also provides excellent
`seal against irregular base building connections. 1” (25mm) thick batt
