You have air in the pipework. What that means is that there is a low level of water in the system and the boiler is boiling the water instead of heating it. The result is the fast expansion of the pipework is causing the banging noise.

I'd have done what you have already done re: Padding the pipes were they cross joists etc with some foam pipe insulation, Reattaching any lose clips. Ensure they are not too tight to allow the pipes to expand. Maybe ensure all the radiators are bled so there is no air in the system. You could maybe turn the temperature down slightly on the boiler so the water is not quite as hot. If you have a system that is hot water cylinder / central heating. Adjust the controls so when the system comes on from cold it heats the radiators first so the water gradually gets warmer (Rather than heats the water and then switches the hot water to the cold pipes of the radiators).

I had this a while back. It could be air in the pipe. In our case it was a problem with the pump. It wasn't running high enough so the water couldn't get through the system. If your pump is outside the boiler, you could check and try increasing the pump rate.
Best bet, if not is to call a plumber. The banging is going to put pressure on the pipe joints eventually and it could end up making things worse.
I hope this helps.

Air and heat. Heat expands most pipes as they are metal (some now are plastic type) air should be bled out - do it when the heating is off and the pipes have cooled .

Air in the pipes. Bleed the radiators with the little key.

Sometimes its air, but mostly its just the heat making the metal pipes expand a little !.

AIR!
I had this problem for years and years. sunded like there was a ghost in the attic!
Turn the temp up to full, the pump in your tank cupboard up to its fastest and bleed all your radiators and that shud flush out all the air from your system through the expansion tank and overflow.
the air could be coming in from various sources but its likely to be just a build up from the o2 in the water but if it continues get a check up from a plumber. I changed my pump and since ive had a nice quiet house

Expansion caused by the heat.
