Best fixings for aerated block walls
Discussion
You can use plugs and screws, just don't use the drill on hammer action, just rotary drill, this will give you a tighter hole. Make sure you use the right size drill bit for the plug you are using. Make suer you hammer the plug into the hole, don't have it gripping the plaster
I also double plug for heaver stuff.

I used Fischer hybridpower plugs on my thermalite wall to hang a tv.
As above no hammer action just the correct size masonry bit and drill a bit deeper than spec as the dust clogs up the hole and means the plugs don’t go in far enough.
Seems pretty secure and have held the TV up on an Extendable bracket for a few months now with no issues.

And I decided this was too risky drilling multiple holes close to each other in thermalites. You could potentially have several fixings in 1 block.
I’m sure they are study but as I said for a fairly light modern TV it’s way over the top.

I bought the rigifix but decided they are overkill for hanging a normal LED TV on a bracket.

I used the M8 ones for a pivoting arm TV bracket that only has two fixings - it can extend out a bit and I was concerned about leverage. Wall was dot and dab then breezeblock.

I reckoned I could have hung a ship off just one of them. I'm not sure you'd be able to screw the metal insert into the plug just using the allen key - I used their adapter into a powerful battery drill / driver and it did it OK.
The walls are dot and dab onto aerated concrete (Thermalite is one brand) and would probably use the smaller version. Whether it gets 4 or 8 depends on how they feel.
Tried unos (my favourite for any other material) to fix something else on Friday and they wouldn’t hold in the blocks.
Breeze blocks are much harder and much easier to deal with.
Not worried about overkill as the TV may get bigger in a year or so!
