Heavy duty thermalite block fixings?

[stuartpaul]

I've got to hang a very heavy radiator off a plasterboard dot and dab on thermalite block wall. Clearly I'm worried about ripping the fixings out of the wall (6 no) and wondered if anyone has direct experience of such issues?

I've found these http://www.amazon.co.uk/Rigifix-Drywall ... B0032P5K96 which appear to get a good write up elsewhere and would appear to do the job.

Alternatively resin is a possibility but I've no experience with it and lining up 6 fixings before the resin goes off worries me as there is little room for error.

Suggestions and recommendations please?

I find these good for fixing through dot and dab, don't know if they are up to what you need though?

Thanks Doug,

They reckon it'll work and at that price I can afford a trial first.

I've used both the above on fixing battens to a dry lined wall on thermalites to secure a bath.

I found Rigifix better than dryline pro though still had a couple of fails where the fixing started stripping in the block.

Consider also GripIt http://www.gripitfixings.co.uk/. I've tried these as well but found them very fickle and need to be fitted just right.. The principle is good one though as they are designed to hang heavy weights.

My friend (a brilliant chippie) worked in a home for autistic children where the ceilings were 18mm wbp because they were so destructive - he watched child grab a door handle that had come loose and wind the spindle into a helix. By the bye ... he always used wood screws straight into the block with a small pilot but no plugs or resins. He said he had done this for years and he'd not had a problem.

I only use screw's into the block (thermalite) 4" when on site but you can't beat a cut nail for skirts, arkie's, door caseings ect

Can wholeheartedly recommend these. Had to hang some heavy cupboards and think someone on here recommended them. Very solid secure fixing and easy to do.
