Thermlite wall - guide for max load (radiator)

There's not very much "moment" even with a heavy radiator (as long as someone does not try to climb it like a ladder). I think you are worrying unnecessarily, especially with your dog-leg (provided the blocks are properly laid to key the walls together). It is probably worth using a reasonably long fittings. I've never used Multi Monti's in lightweight blocks, but they might work well, perhaps using a drill 1/2 mm smaller than you would use with normal blocks or bricks.

Hiya,

I always like to factor a little abuse in (visiting little kid, someone hanging heavy wet coats on it etc) :)

I think you are

Can confirm that:

That's properly coursed around the corners.

That much I do have an answer to (having fixed to the other side of this for bog cistern and free hanging basin):

I'll either use resin fixings 3/4 the way through the wall or these bad boys:

(which I have used before). The wall will come down before they let go!

I guess you're right - it's just before that wall was plastered, I chased it for conduit and the top block jumped off its mortar, so my confidence went through the floor.

I'll probably aim for 3rd course from top - there's a lot of interlocking at that stage.

Thanks mate!

I was worried as you hear the odd story of gable end walls falling over after someone hung a boiler on the inside, or occasionally due to very high winds...
