What is the coverage of Thistle GypPrime?
Thistle GypPrime can be diluted, normally a ratio of 1:5 parts water provides adequate suction control, or it can also be used neat if necessary to control extremely severe suction. One tub covers up to 600 sqm (diluted 1:5) or 100 sqm undiluted.
Can I use any woodscrew when fixing to Gyproc Habito?
We recommend the use of a No.10 woodscrew comprising of a single thread. Fixings with cross threads will reduce fixing performance of the board.
What is the fixing capability of Gyproc Habito?
A No.10 woodscrew is capable of a maximum load of 15kg per fixing at safety factor 4.
What is the maximum cantilever of Gypframe MF5 Ceiling Sections?
What head and base tracks should I use?
Within our GypWall partitions, heights below 4200mm the appropriate width of standard folded edge (FEC) Gypframe Floor and Ceiling Channel can be used.
For heights between 4200mm and 8000mm, the Gypframe Deep Flange (DC) Floor and Ceiling Channel should be used and for heights above 8000mm the Gypframe Extra Deep Flange (EDC) Floor and Ceiling Channel should be used. Additional considerations need to be given if there is a deflection head requirement. Please refer to our White Book Specification Selector for details.
What is the vapour resistance of Gyproc WallBoard Duplex plasterboard?
Gyproc WallBoard Duplex and Gyproc FireLine Duplex have a water vapour resistance factor (μ) 1400 EN 14190: 2014. Condensation is common where cold meets warm in areas like roof spaces and external walls. The board's vapour control backing stops condensation entering in these areas, preventing it from affecting the structure of the building.
What screw lengths do I use for fixing to metal and timber?
The screw should be the thickness of the board plus a minimum 10mm penetration into Gypframe metal or the thickness of the board plus a minimum 25mm penetration into timber using our British Gypsum screws.
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.
Why might the use of resilient bars fail to meet the claimed sound insulation benefit?
The resilient bar might be fixed incorrectly (wrong orientation) or the incorrect length of screw may have been used when fixing the plasterboard.
The resilient bar should be fixed horizontally with the bars perpendicular to the metal studs, with the fixing flange generally at the top of the bar. Consideration needs to be given to the detailing around openings.
It is important to ensure that the correct screw length is used when fixing plasterboard to resilient bars otherwise it could result in the screw coming into contact with metal stud. This will reduce the sound insulation performance of the system by creating a bridge which will conduct sound. Resilient bars are 16mm deep and the appropriate Gyproc screw should be selected to penetrate only 10mm through the metal. It is also important that services, fixtures, etc, do not form a bridge between the lining boards on each side of the partition.
