Q&A: GIB Plasterboard
People from the trade talking to people in the trade has always been the focus of the Training and Support Team at Winstone Wallboards. Whether that’s from behind a drawing board or on the building site.
One of the core responsibilities the team has is to man the GIB® Helpline which takes calls from all over the country.
Below are some of the most common plasterboard related questions received:
Q.1 Can I substitute one manufacturer’s component for another manufacturer’s component in a tested system like bracing, fire or noise?
A.1 The industry is becoming more aware of substituting specified components and how they may impact on both performance and compliance. It is not possible for manufacturer’s to test all combinations that include other manufacturer’s components. “If you choose to substitute a component in a tested system, then the responsibility lies with you to verify that it is suitable for use (in all respects)”.
What this means is that you need to make sure it’s ok with not only the supplier (that the component performs the same as the original specification). You may also need to check that it is ok with the local authority that they will accept it.
Q.2 In a fire rated wall system, can I substitute GIB Braceline® / GIB Noiseline® for GIB Fyreline®.
A.2 Yes you can. (Refer to page 16 of the current GIB® Site Guide) More of the dwellings being constructed in the main centres involve apartments, inter-tenancy or terraced styled homes. This means that more buildings are requiring
performance systems to provide separation and quite often these require multiple performance systems within the same wall.
Q.3 What sort of glue can be used in a GIB® fire rated system?
A.3 Glue cannot be used in place of mechanical fasteners in a fire rated system. The plasterboard relies on the mechanical fasteners to keep it against the framing. That’s why the fastener length and pattern are important and a builder needs to be familiar with these details before starting the work.
Q.4 What do I do if I have installed the GIB® plasterboard using glue in a GIB® fire rated system?
A.4 If you have used glue it will not be detrimental to the performance of the GIB® fire rated system. If there are any daubs of glue it is likely that it will melt within the cavity of the wall.
Q.5 Do I have to stop the first layer in a two layer GIB® fire rated system.
A.5 No you don’t have to plaster the first layer. When a two layer system is being installed the second layer is offset to the first layer and this provides protection at the joint. However you are still typically required to get the first layer inspected prior to the second layer being installed.
