What insulation can be used to achieve the acoustic performance of a partition system?
Siniat Partition and Shaftwall systems can include glass mineral wool insulation in the cavity of the system to obtain improved acoustic performance over the empty cavity equivalent. Siniat do not mention a particular manufacturer of glass mineral wool so to achieve the quoted performance the thickness of GMW insulation used must be at least that

Where a Siniat Thruwall system interfaces with a Promat encased steel is the complete elevation covered by the Thruwall warranty?
The Siniat Thruwall warranty covers the tested Thruwall system only and does not include any surrounding structural frame even if encased in Promatect fire protection systems. The Promat encasement systems are covered by their own product warranty and system performance is covered by third party certification.

Can Siniat support timber frame partitions?
Siniat have limited data on timber frame partitions (Loaded and Un-Loaded). Advice can be given wherever possible, however it is recommended to seek advice from the STA (structural timber association) or other specialist bodies dealing with timber frame systems which may be able to advise more on the boarding required to suit performance criteria. T

Can 3rd party collated screws be used with Siniat partitions as they are not in the Siniat range and will this effect the system warranty?
The only collated screws that Siniat currently offer are the Siniat Collated Wet Area Screws . Siniat do not supply collated screws for standard partitions. If it is desired to use a collated screw, it is acceptable to source a 3rd party fixing for installing the plasterboards to the frame as long as the following criteria are met: The chosen col

Do you have to line framed opening in the Siniat Thruwall System?
The standard recommendation is that all framed opening with-in Siniat Thruwall systems should be lined with layers of 12.5mm GTEC Weather Defence board to maintain the system performance in these locations. As ever this should be checked and confirmed with relevant window, ducting or firestopping manufacture to ensure that this lining meets their p

Does the Siniat Tilebacker board provide or contribute to the fire resistance of a system?
Siniat Tilebacker board has not been tested as part of a system for fire resistance. The board is classified as A2,s1-d0 for reaction to fire similar to other internal plasterboards in the range. To create system with a specific fire resistance period, specify internal plasterboards to meet all requirements (fire, acoustic, robustness, height) then

How should a profiled soffit be detailed to maintain performance of a partition fixed to it?
When fixing the head of a partition to a profiled rib deck, the profiles must be fire stopped to maintain the same fire resistance performance as the partition below. There are specialised products that are available from fire stopping manufacturers to suit this purpose and guidance from the relevant manufacturer must be sought to ensure they are in

What configurations can I use Siniat Securtex in to achieve SR 1 for SBD requirements?
The following table from the Securtex brochure details the tested systems to meet SR1 of SBD. Our full Securitex brochure can be downloaded from our website (https://www.siniat.co.uk/en/performance/securtex) for all details on the concept, design considerations and comprehensive installation guidance.

Does Siniat have solutions for X-Ray rooms?
Siniat do not have any specific solutions for rooms that generate X-Rays. When specifying partitions for such areas, the core wall will be designed to meet the fire resistance, acoustic, duty and height criteria. Siniat boards are not inherently capable of stopping X-Rays. Third party companies take plasterboard from various manufacturers and bond
-
Can Siniat boards be used on 3 party metal framing?
Siniat will only support the build of a complete Siniat system using its full range of board, framing and accessories. Only this attracts the Siniat Warranty and support from its technical and specification departments. Siniat systems are tested with its complete range of products. It is possible to use 3rd party components but this will be at the

What fire and acoustic performance is possible with Siniat A1 Shaftwall systems?
The fire and acoustic performance of the Siniat A1 Shaftwall systems are dependent on full system build-up. See the Siniat Drywall Manual -Shaftwall Section for full details. The two system variants available are shown below:
