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?
How do you fire upgrade a lath and plaster ceiling?
Underdraw the existing lath and plaster with chicken wire (supplied by others and fixed in accordance with manufacturer recommendations).
A cavity should then be formed by counter battening with minimum 38 x 38mm timber or by using GypCeiling Lining. Various Gyproc plasterboards can then be screw fixed to the underside of the battens depending on the fire performance required.
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.
