Add a noggin 


(00:08) Good planning will ensure noggins are detailed in the design of the frame at times a sparky or plumber may need an additional noggin these can be easily installed on site if additional noggins are required there are a number of options available here we will look at using an adjustable commercial noggin and also at making a noggin out of timber or steel commercial noggins are adjustable to the size required and simply inserted between the studs leveled and secured using the correct fasteners a number of commercial brands are
(00:43) available [Music] if using a timber noggin as shown here once measured to the required size rebate a groove to slot into the lip of the c-section treated timber is incompatible with steel frames and must be isolated from the frames or trusses best practice is to apply the membrane to all contact surfaces of the frame [Music] the noggin is then inserted leveled and
(01:46) secured with the correct fastener [Music] you can also easily make a steel noggin on site noggins can be made in a number of ways to fit the connection required the maker noggin fact sheet provides a step-by-step guide in the video here you can see a noggin being made using a pre-notched noggin [Music] the new noggin can be easily cut to size
(03:16) using tin snips [Music] notch out the return lips [Music] and then using a vise grip fold up the
(04:21) tab [Music] the new noggin is inserted and outside screws fastened [Music] [Music] then changing to a 10 by 16 drill bit screw fix the back section the longer drill bit allows a deeper angle and ensures the screw is correctly fixed.
 

Making New Noggins

LGS structures are designed to have numerous noggins to support both the structure and its fixtures and fittings. Examples of these fixtures and fittings are:

  • Curtain hardware
  • Plumbing outlets
  • Bathroom fittings
  • Television wall for mounting large heavy screens
  • Suspended vanities
  • Wall mounted rangehoods
  • Grabrails/ Handrails

 

At times these additional noggins may have been missed and need to be fabricated on-site, which can be easily achieved by adjusting proprietary products, which can be purchased, or by making them from LGS or timber.  If you find that you are continually fabricating noggins for the same purpose, speak to your frame fabricator or builder and request those elements be included for future structures’ detailing and fabrication.

Numerous proprietary noggins can be purchased, such as EzyStud, which is shown below and already has an impermeable membrane installed for dissimilar metals. These have adjustable dimensions and can be easily inserted, plumbed and fastened between frame studs at the desired location.

Ezystud proprietary noggin

This is an easy, multi-step process that is best reviewed via the TRUECORE® steel Making up Noggins and Studs Guide, which can be accessed in the Resources section below.

To create timber noggins, follow these steps: 

  1. Cut timber to the appropriate size.
  2. Cut rebates to slot into the stud “C” section.
  3. If using timber or treated timber, remember this material is incompatible with LGS and therefore must be isolated from the metal using an impermeable membrane.
  4. Apply impermeable membrane to all contact surfaces of the frame.
  5. The noggin is then inserted, plumbed/levelled and secured using the specified fasteners. 

If attaching dissimilar metal fixtures like copper, brass or stainless steel remember to isolate with impermeable membrane or polyethylene packers etc.

For more information on the isolation of steel from timber and dissimilar metals, refer to BlueScope Technical Bulletin TB34, CTB12 and CTB13 in the Resources section below.
