The external pipe should be 32mm to prevent freezing. And external

Any suggestions on the most suitable insulation to use?

Have dancing shoes, will ceilidh.

Well I have the 32 mm pipe and is about 9 inches from where it exits outside
to the trap so I will get something for way of insulation.

Mine drain pipe comes through the wall a course or so above dpc, then drops
to outside slabs level using 2 x 45 elbows, then on to a gully about a
metre or so sway. I've not had any trouble with freezing, even though the
drain pipe has had a covering of snow at times.
