New heating system install,notching stopping creaking boards

[brummieaxgt]

Hiya just fitting a heating system and whats the best method of preventing creaking.Im notching the joists for the pipework.
Should i notch enough for a clip to be fitted to the joist and pipes clipped in?
Or should i even clip?
If the notch is deep enough and wide enough it shouldnt creak right?


Any help appreciciated.
thanks

I always cover my pipes where they cross/touch joists with tubular hairfelt.

Or slips of plastic sheet where they pass over the joist. Helps them to slip during expansion.
