What goes up must come down, but preferably not unintentionally on someone’s head! We answer the frequently asked question: can you use Button-fix for hanging ceiling panels?
While most people are drawn to the Type 2 Button-fix, actually this is not the one which we would recommend for this purpose. It is the Type 1, or if a push-on panel is essential, then the Type 3.
From the Type 1 Button-fix strength testing reports (downloadable on each product page on this website) and using figures based on the maximum perpendicular pull-out force rather than shear force, we can ascertain a maximum panel weight. For example; when mounting an MDF panel using four Type 1 Button-fixes, a maximum mass of 150kg (330 lbs) may be supported (including a 1.4 safety factor), which gives plenty of safety margin when hanging an average panel!
Type 2 Button-fixes are NOT suitable for ceiling panels if the panel load is pulling directly to disengage the Fix and Button. Even if a ceiling panel under test appears secure and the panel weight is well below the Fix disengagement force, the steady load on the Fix ‘jaws’ causes creep in the nylon polymer, which may lead to the panel disengaging, days or even weeks later. That would be a nasty surprise for someone in the wrong place at the wrong time.
Although Type 3 Button-fixes are a direct ‘push-on’ engagement like Type 2, they have a significantly higher pull-off load and a much better resistance to creep than Type 2. Therefore, we can advise a maximum load of 10kg (22 lbs) for a ceiling panel held with four Type 3 Fixes, or 2.5kg (5.5 lbs) per Fix (provided the screws and the panel materials are correctly matched).
For critical applications, such as large panels in public areas, and in maritime/transport interiors, we always suggest using safety cords or chains.
However, for the ultimate strength fixing for ceiling panels, the Type 1 Button-fix is your answer. And if the ceiling is located in an area where fire rating is a consideration, you should chose the Type 1 Metal Button-fix.
Hanging panels using a demountable system such as Button-fix makes them easier to repair, repurpose or refurbish, ultimately reducing waste.
Any direct push-on panel fixing must be strong and reliable for the duration of its life. At Button-fix, we have put the new Type 3 through exhaustive testing to make sure we can confidently give recommended loadings that will pass the test of time.
