Hanging a rad on a plasterboard and osb wall

alwaysproblems · 2026-05-21T20:18:15+0100

I'm looking to hang a 3 column vertical radiator approx. 45kg unfilled on a plasterboard on OSB wall.

Will I need to reinforce this or will the combined strength of both with some heavy duty fixings be adequate.

Thanks.

What thickness is the OSB? If not too thin it'll be fine with plenty of fixings into that.

If that's 9mm OSB onto proper batons then it should be ok. Try and pick up the batons for at least the top brackets and use nice large fixings, or if it's easily opened then run an extra baton in for the top brackets

Pretty sure its 11mm

No problem, the forces acting on brackets are predominantly downwards/vertical, chunky screws and it'll be fine.
