A Brief Guide to Types of PartitioningPublished 14/04/2020
Plasterboard Partitions (drywall)
Drywall partitions are constructed on site from a framework of steel or more traditionally timber studs, faced with one or two layers of gypsum plasterboard. The void can be left empty or filled with a glass mineral wool substance, depending on the fire or acoustic requirements. This type of partition is widely recognised as being the best for sound attenuation.
Modular Partitions (relocatable)
Where flexibility and a cellular environment and required, modular panel partitioning can be installed between the floor and underside of the ceiling or soffit. These systems can achieve high levels of attenuation, flexibility, in addition to a fast, dry installation.
Glass in a partition can perform at good levels of attenuation, especially if double glazed using different thickness of glass or if toughened glass is mixed with a laminated glass. Some laminated glass products use special interlayers to achieve an enhanced acoustic rating. These types of glass originally developed to improve attenuation to external glazing near airport, have migrated to commercial interiors as costs have fallen.
Designers should ensure from the outset that reverberation caused by sound reflecting from hard surfaces such as glass will not make the space uncomfortable to work in. Incorporating products with a high sound absorbency can help offset the effect of large amounts of glass or hard surfaces. It is important to ensure the glass is not parallel to other reflective surfaces, and circular glass rooms should be avoided, where possible.
