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.

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?

Using different combinations of board and insulation, various system options are available with fire resistance periods of 30, 60, 90 or 120 minutes. Use the Technical Enquiry Form in the Technical Support area of the website to request information for your specific requirements.

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.
