Brockway Padstow is a 100% undyed wool with a published TOG value of 1.54. Padstow is a 100% undyed wool carpet rated 1.54 TOG. It pairs with underfloor heating only alongside one of the lower-TOG underlays.

Using the UHMA rule, in-situ resistance is carpet plus underlay minus 1. To keep Brockway Padstow under the 2.5 TOG limit the underlay must be no more than 1.96 TOG.

TOG measures thermal resistance, so a low number means heat passes through easily. For a floor covering over underfloor heating that is what you want. A comfort underlay chosen for warmth underfoot does the opposite job and is the usual reason a heated floor underperforms after a carpet goes down.
