Can I use the moisture resistant version of a board and still achieve the same performance?
Where moisture resistance is required in a British Gypsum partition, lining or ceiling, the moisture-resistant version of a board, in the same thickness as the original specification, can be used without impacting the system performance.
How do I install service penetrations in British Gypsum systems?
If services are required to penetrate a British Gypsum system, the system performances must be maintained. This includes fire resistance, acoustic separation and structural integrity.
What head and base tracks should I use?
The type of head and base track you need is detailed in the Technical Specification document for the solution you choose. The head track may also change dependent on deflection head requirements.
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.
What is the sound insulation performance of Gyproc plasterboard?
What can cause acoustic failures?
There can be many reasons for sound insulation failures such as air leakage paths, flanking transmission, inappropriate specification and poor workmanship.
How do you upgrade the fire or acoustic performance of a timber floor from below?
What is a parge coat?
What is a deflection head?
There are details used at the top of partition systems when needing to allow for structural movement of the floor or roof above.
