The diagram shows what Corefix can hold and 250kg is almost 39.5 stone or 3/4 averagely built people – That is very impressive indeed. How and Where do I buy Corefix? Corefix can be bought from most high street DIY stores today including B&Q, Screwfix and the similar. Remove any dust or debris from the hole before gently tapping the Corefix plug into place until the flange sits against the plasterboard. Originally designed to safely secure wall hung kitchen cabinets Corefix fixings are now used to support any heavy loads on a hollow cavity wall including:

A screw, in this gap, is not supported and any heavy load applied to the end of it will cause the screw to bend. In 2017 statistics show that almost 80% of people are installing TV’s which range between 40 and 55 inches (Source Statisista.com). This clearly depends on the size of the television but with all the major brands such as Sony, Samsung & Panasonic all making flat screen TVs up to a staggering 100 inches and above in some cases, it really is important to know the weight of your TV and know your hollow wall plasterboard fixing will support the load. Below are some approx. weights for standard size wall mounted flat screen TVs* This can result in cold spots on the wall which, in turn can result in condensation and condensation around the window reveals of a dot and dab plaster boarded room is very common.

Corefix can be installed in less than one minute, without the need for specialist tools – all you need is a 10mm masonry drill, hammer, and a screwdriver:

It does however have a few pitfalls, not the least of them being thermal bridging where the cold temperature of the masonry is transferred, via the plasterboard adhesive, to the inside of the plasterboard wall.It’s no secret, we love them! This hideous problem that has plagued us (and many many others) for many many years has now magically gone away thanks to Corefix. Drill a hole through the plasterboard and into the solid wall behind, ensuring the total depth is a minimum of 100mm. Because it is bent, the downward force of the attached object starts to tilt outward as the image above shows. This stops the force being 100% downwards and moves it to an angle which, after time, starts to pull the screw out of the wall.
