81 Sound Barriers

Aim

To reduce sound transmission and acoustic disruptions through sound barriers.

Detailed requirement

Part 1: Wall Construction Specifications

The following spaces, if present, have interior partition walls that meet the Noise Isolation Class (NIC) described:

Enclosed offices: minimum NIC of 35 when a sound masking system is present, or minimum NIC of 40 when no sound masking system is used.
Conference rooms and teleconference rooms: minimum NIC of 53 on walls adjoining private offices, conference rooms or other teleconference rooms.

Part 2: Doorway Specifications

Doors connecting to private offices, conference rooms and teleconference rooms are constructed with at least one of the following:

Gaskets.
Sweeps.
Nonhollow core.

Part 3: Wall Construction Methodology

All interior walls enclosing regularly occupied spaces are constructed for optimal performance by reducing air gaps and limiting sound transmission through the following:

Properly sealing all acoustically rated partitions at the top and bottom tracks.
Staggering all gypsum board seams.
Packing and sealing all penetrations through the wall.

Our contribution

To reduce sound transmission between adjacent spaces, Saint-Gobain delivers high performing acoustic glazing.

Our glass doors and partitions, made from sustainable materials, are a great way to separate spaces and keep privacy within an open-plan office. STADIP SILENCE, fitted as single glazing, is particularly recommended for all glazed partitions in offices, meeting rooms and interpreting booths. A single pane of STADIP SILENCE can dampen the sound by up to 47 dB and in a double-layer construction it can exceed 50dB.

For more workspace flexibility, the CLIP-IN SILENCE removable partition system and CLIP-IN SILENCE DOORS can also reduce sound transmission from adjacent spaces. These are made with PVB Silence that has a special dampening viscoelastic core, helping to further reduce the transmission of sound.
