Tredaire Colours Green TOG rating and underfloor heating
The published TOG and datasheet figures for Tredaire Colours Green, and what it means over a heated floor.
Leaves 1.03 TOG of the combined budget for the carpet on top before the 2.5 TOG limit is reached.
| Manufacturer | Interfloor (Tredaire) |

| TOG rating | 1.47 TOG |
| Thickness | 10.3 mm |
| Density | sponge rubber, waffle |
| Sound | sponge rubber, waffle |
| Underfloor heating | Not suitable |
Colours Green is a 10.3 mm sponge-rubber waffle underlay rated 1.47 TOG. The thickness and resistance put it above the 1.3 TOG underlay ceiling, so it is a comfort choice for unheated rooms rather than over underfloor heating.
Because Tredaire Colours Green is already 1.47 TOG before any carpet is added, no carpet brings the pair back under the 2.5 TOG limit. Over underfloor heating, swap it for a low-TOG underlay instead.
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.
