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.
Do I need timber noggings when boarding a ceiling and if so what is required?
This depends on a number of factors such as joist centres, board thickness, and performance requirements (e.g. vapour resistance and fire resistance performance).
Please refer to our White Book Specification Selector for more details. If noggings are required they are typically 38mm x 38mm or 50mm x 50mm timber, located between joists at the ceiling perimeter and to support the edges and/or ends of the plasterboard.
How do you achieve a fire-rated timber stud partition?
What are GypWall Staggered, Twin Frame Braced, Resilient, Twin Frame Audio stud partitions?
All of our lightweight metal stud partition systems incorporate various plasterboard products offering a range of fire performances, sound insulation and duty ratings.
What are the linings systems available and how would you select the correct type?
Are timber inserts required to metal stud partitions?
Timber inserts (such as plywood) are installed to support additional loading which is beyond the capability of the Gypframe components, for example when accommodating sinks and grab rails.
Our Gypframe Service Support Plate, which carries 18mm plywood within the cavity of the partition, provides a strong background for fixings through the plasterboard lining.
