We often receive inquiries regarding fixing to plasterboard or drywall; here's a brief summary of ways we have tested and found to work well.
If possible, for maximum strength, always try to fix through to the wooden studs, joists, or beams behind a drywall or ceiling. However, where this isn’t practical, there are some good options available.
First a note of caution. On ceilings, the drywall can be sometimes as thin as 9.5mm (3/8"), which makes it quite fragile. We don't recommend installing Button-fix onto 9.5mm (3/8") drywall unless the screws attaching either the Fixes or the Buttons are screwed through into the supporting beams.
In most other cases, drywall is usually 1/2" thick or greater, and it is often doubled up to provide additional strength and acoustic properties. For these applications, we particularly recommend using metal cavity fixings, like Rawlplug SM Interset M5 fittings, or the equivalent Fischer HM M5 metal cavity fixings. We have successfully tested both Type 1 and Type 3 Button-fixes with these cavity fixings and 1/2" drywall. Ø1" 'fender' washers should be placed under the Buttons to help spread the load. We also found that the cavity fixings are best installed with the manufacturer's installation pliers. Ensure you choose the correct length of cavity fixing for the thickness of your drywall.
Interset fixings have the advantage that they remain firmly attached after removal of the screw, allowing extra washers to be easily added, to space-off and level the panel if necessary.
When attaching green Type 1 Buttons using Intersets, the standard pan-head M5 screws that are supplied with the fitting need to be swapped out, after installation, with suitable length countersunk M5 screws.
Other common heavy-duty drywall fixings can work with Button-fix too, for instance, spring toggles, Zip-fix cavity fittings, and Bullfix fittings. These should all be used with a Ø1" fender washer behind the Button, just like the Interset fixings. Spring toggles have the disadvantage that they require a large hole, which can cause inaccuracy in the final placement of the Button, and if you remove the screw, the toggle falls down the back of the drywall!
We don’t recommend self-drilling metal or plastic fittings. They are not strong enough for most Button-fix applications.
By following these instructions, Button-fix products can support substantial loads, up to those specified for the drywall anchor by their manufacturer, and also withstand many cycles of removal and replacement on both walls and ceilings.
PET acoustic panels have become popular, especially as they are often manufactured from recycled post-consumer waste such as water bottles. However, they are commonly glued to sub-panels or directly to walls, making them difficult to remove, reconfigure or reuse elsewhere. Mounting the panels with Button-fix, on the other hand, makes removal easy.
The Router Multijig makes machining the oval rebates for all Type 1 Fixes easy and precise. See the useful accessory in action.
Fitting Type 2 Button-fix is simple and accurate, when using Fix Marker accessories. This three-minute video shows how.
