New heating pipe underfloor - felt or foam?

[r_c]

(Ignore the gas pipe - it is being removed.)

The hot water pipes that go to the radiators and underfloor heating under the ground floor are insulated with felt. Is this sufficient or should I ask for the foam insulation?

And if I use foam, how to you insulate the bits where the clips are?

Felt sleeving is as much use as wearing a wet suit in the Arctic. A small piece of foam is cut out the back where the clips are.

Thanks for the pictures of hair felt my arms are itchy just looking at it, complete waste of time use foam
