Below you’ll find all of the information needed to complete wall lining, partition, floor and ceiling systems, no matter the size and complexity of the project specification.
How do you fire upgrade a lath and plaster ceiling?
First, the existing lath and plaster ceiling should be fully retained with suitable reinforcing, for example, chicken wire, which should be designed and fixed in accordance with guidance from a structural engineer based on the calculated weight of the existing ceiling. This is to prevent a situation where an old ceiling falls onto the new GypCeiling lining, therefore, adding additional weight which the new system is not capable of supporting.
How do you protect a steel column within a masonry wall?
Our FireCase system can be used to provide fire protection to steel columns within a masonry wall.
The thickness of Glasroc F FireCase board to be applied will depend on the section factor of the structural steel (A/V), if you need help with calculating this please get in touch with us by filling out the Technical Enquiry Form.
For ceiling constructions the Gypframe GL1 Lining Channels are located at 450mm (for 12.5mm lining) or 600mm centres (for 15mm lining) and Gypframe GL2 Brackets, Gypframe GL9 Brackets or Gypframe GL12 Brackets are located at 1200mm centres.
What are the screw fixing centres for partitions, ceilings & encasements?
In general terms for partitions, screws are located at 300mm centres (200mm centres at external angles). For ceiling systems, the screws are located at 230mm centres within the field of the board and 150mm centres at board ends. For encasement systems, screws are located at 150mm centres.
However, these general guidelines may vary depending upon the system being used so always check against specific systems for your reference.
What is the fire resistance performance of Gyproc plasterboard?
Fire resistance performance is based on complete ‘elements’ such as a partition, wall, ceiling membrane or floor, rather than the individual plasterboards that only form part of these constructions.
How much space is required to encase steel sections?
It depends on which product and system is being used. We offer a choice of two systems depending on requirements, firstly the FireCase system which uses the Glasroc F FireCase board to form a frameless encasement around the beam or column, and secondly the GypLyner Encase system which uses Gyproc FireLine plasterboard mounted on a Gypframe metal framework.
With the FireCase system the space used could be as little as 15mm which is the Glasroc F FireCase board itself. The GypLyner Encase system requires more space due to the metal framework between the plasterboards and the steel section.
