Illustrative imageQuick answer
Single glazed office partitions typically achieve around 30 to 38 dB Rw and double glazed partitions 45 dB Rw or more. For confidential meeting rooms, double glazing with acoustic door seals is usually the right choice.
What dB Rw means
Rw is a laboratory measure of how much sound a wall blocks. Higher is better. On site the result is usually a few decibels lower because sound travels around walls through ceilings, floors and door gaps.
Weak points
Doors, ceiling voids and trickle gaps at the head and base of a partition let sound through. Acoustic door seals and ceiling barriers above the partition line make a bigger difference than upgrading the glass alone.
Choosing a system
Use single glazing for general rooms and open-plan division, double glazing for HR, boardrooms and client rooms, and add acoustic treatment inside rooms to cut echo.
