Brockway Lingdale is a 80% wool wool-blend with a published TOG value of 1.57. Lingdale is a wool-blend carpet rated 1.57 TOG. Only the lower-TOG underlays keep the combined figure under the limit over a heated floor.

Using the UHMA rule, in-situ resistance is carpet plus underlay minus 1. To keep Brockway Lingdale under the 2.5 TOG limit the underlay must be no more than 1.93 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.
