Metal Stud Partitions
Metal stud partition has been around for many years, and usually comprises a 50mm stud with either one or two layers of plasterboard on either side. The central cavity can be filled with fibreglass or mineral fibre for additional sound proofing.
Other sizes of studs are also available, up to 150mm “Jumbo Stud” which is often used for factory firewalls. Firewalls can be built to over 10,000mm high, and up to two hours fire rating. Jumbo stud firewalls are often used to divide warehouse/factory premises, where a fire compartment is required. The extra width of the studwork provides stability where the partition wall is high. Two layers of plasterboard on each face also creates a laminating effect which increases stability. This is especially important where the installation could be subject to wind load.
