How to Install a Radiator onto a Dot & Dab / Drylined Wall
- Mark required location of radiator fixing holes or radiator fixing brackets, these are normally pre drilled. Generally a minimum of four Corefix dot & dab wall fixings should be used per radiator. Drill hole to required depth using a 10mm masonry or SDS drill bit.
- Ensure all debris and dust has been removed from the hole. Gently tap the Corefix plug into place until the flange contacts the wall surface.
- Then tap the metal core into place until it is flush with the Corefix plug flange.
- Offer the radiator up to the wall ensuring two people support any heavy items and if placing onto brackets lift carefully into position. /if direct fixing through radiator screw back to the wall using the supplied screws. Ensure radiator is totally secure and that screws are ‘tightened up’ in all fixing locations.
Will Corefix Support my Heavy Radiator?
Corefix has been designed from the ‘ground up’ over two years with the goal to manufacture a fixing to carry extra heavy loads on dot and dab / drylined walls. Unlike plastic versions, the steel core in this cavity wall fixing transfers the load from the plasterboard to the solid blockwork or masonry material behind and whilst other frame fixings claim to perform the same role these can severely distort or crush the plasterboard into the void. A radiator would normally be supported on four fixings and as Corefix has been tested to support 250kg on four fixings they will support the largest ‘designer’ radiators on the market today.
