Is Gyproc FireStrip required?
This is used within our Internal Partition and Shaftwall systems with deflection heads (when needing to allow for movement within the structure at the head of a partition created by live and dead load on the floor or roof). The Gyproc FireStrip is an essential component in maintaining the fire resistance performance at the top of a partition with a deflection head.
How do you upgrade the fire or acoustic performance of a timber floor from below?
We offer a wide range of ceiling systems such as GypCeiling MF and GypCeiling Lining, incorporating Gyproc SoundBloc or Gyproc FireLine board in conjunction with Isover insulation.
Another option is Gypframe RB1 Resilient Bar fixed direct to the underside of the floor joists.
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.
What centres are Gypframe GL1 Lining Channels, Gypframe GL2 Brackets, Gypframe GL9 Brackets, and Gypframe GL12 Brackets installed when fixing Gyproc plasterboard (GypLyner wall & GypLyner ceiling systems)?
For wall constructions the Gypframe GL1 Lining Channels are located at 600mm centres and Gypframe GL2 Brackets or Gypframe GL9 Brackets are located at 800mm centres (based upon not receiving ceramic tiles).
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 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.
