I have just bought a canopy what attaches to the house. The bolts I have got with it are 100mm expansion bolts. I have just had solid wall insulation put on my property which is 100mm then rendered. If i use these bolts they will only be seating in the insulation. I cannot find any bigger bolts like these. can anyone tell me what would be suitable to use ?
expansion bolts

Fix from the ground up, i.e build a pillar or concrete some posts in.
Fixing to a 100mm insulated and rendered external wall is not going to be easy or practical. Get the drilling wrong, which will be easy to do if you can't see the masonry below, and you could end up in a right mess.

Surely there a easy way sky put dishes up on these house. Its 15 mm render 100mm insulator the a 9 inch solid wall behind if I could get some type of bolt say 150 mm - 200 mm this would do the job.
That's a bit tricky.
I am thinking maybe, drill through to the wall - drill a hole in the wall, put a sleeve in, then a long threaded rod (chemical anchor or all thread) - then setting chemical.
Then when it goes off, you have a projecting thread to fix your bracket onto.
Will need to be a decent size, as it is cantilevering out a long way.

Sounds complicated. Is there no bolt than are 200 mm in length Or maybe them brick biting screws what window fitters use
Will these do that way I will have 50 mm or so in the first course off wall.

Think these will do as same as what git but these are 180mm so will have about 80mm in solid wall.

It's not complicated; you can buy 1m lengths of threaded bar at B&Q, together with the right nuts and washers.
When using resin fixing, make a wood template to hold the protruding bars in the right position
I half understand what you mean. Can you give a link to the chemical fixing so I know how you apply it and set it ?
Going to go with one of these it will work.

Just one question if its a m16 bolt does that mean I meed a 16 Masonary bit ?

Slightly bigger - 18mm. But most DIY drills won't be capable of drilling holes this size. Would you need to hire one?
I do not think you can mount that canopy on rendered insulation without some sort of plinth to spread the point load. And even then!!!
I have got a sds hammer drill .
There is 3 layers, the initial 9 inch solid wall, then 100mm insulation and render. If you thin about it 80mm of the bolt will be going into the intial solid concrete wall. Are we all thinking the same here ?
So just inject the sleeve and around the thread and let set right ?
Personally I agree with Noseall, but if you must do it your way then at least use sleeves to transfer the loading through the insulated render. Some heavy gauge steel tube may do if you use an anchor that relies on tightening to secure. If using a chemical anchor then you could use back nuts on the threaded rod to tighten against.
The objective is to be able to tighten up the fixings without crushing the insulation which it turn would crack the render.
Remember whatever your canopy weighs it will also be loaded up with snow, ice and winds at some point.
