Cross section of Pipe (see photo)
1 - Carrier pipe: PEX-linked Polyethylene (PEXa) - SDR 7.4
2 - Insulation: PUR - foam - LAMBDA (50) ≤0.021W / mK at 50 ° C

Outsize diameter (OD), Internal diameter (ID)
All our Sanitary sizes our SDR 7.4. This means if you divide the pipe size by 7.4 it gives the wall thickness.
i.e. 25mm, SDR 7.4, has a wall thickness of 3.38mm
