Can I cover the heating film with all types of floor covering?
What is the best insulator for underfloor heating?
2019 July 30Can there be any failures of infrared underfloor heating system?
2019 July 30Yes, infrared underfloor heating film can be placed under all floor coverings. Keep in mind that all floor covering shouldn't exceed 0,15m²K/W (thermal resistance). In case of higher thermal resistance, you should consider other type of floor covering or other type of heating.
Here is the thermal resistance table:
| Floor covering | 1mm thickness floor covering thermal resistance | Thickness of floor covering | Thermal resistance of the covering | |
| Wood planks | min | 0,0430 | 20 | 0,860 |
| max | 0,0610 | 22 | 1,342 | |
| Multilayer parquet | min | 0,0070 | 10 | 0,070 |
| max | 0,0100 | 14 | 0,140 | |
| Laminate | min | 0,0070 | 6 | 0,048 |
| max | 0,0080 | 10 | 0,070 | |
| PVC flooring | min | 0,0110 | 1,5 | 0,017 |
| max | 0,0120 | 3 | 0,036 | |
| Higher resistance PVC flooring | min | 0,0040 | 2 | 0,008 |
| max | 0,0100 | 3,2 | 0,032 | |
| PVC tiles | around | 0,0040 | 6 | 0,024 |
| Glued PVC tiles | min | 0,0040 | 2 | 0,008 |
| max | 0,0100 | 2,5 | 0,025 | |
| Natural linoleum | around | 0,0060 | 2 | 0,012 |
| 3,8 | 0,023 | |||
| Carpets (jute fabric based) | around | 0,0160 | 4 | 0,064 |
| 8 | 0,128 | |||
| Carpets (felt fabric based) | around | 0,0070 | 6 | 0,042 |
| 12 | 0,084 | |||
| Ceramic tiles | around | 0,0012 | 8 | 0,010 |
| 12 | 0,014 | |||
| Terrazzo tiles | around | 0,0017 | 8 | 0,014 |
| 12 | 0,020 |
In the table, there are a variety of thermal resistances stated of the most popular floor covering materials (of 1mm thickness). Multiply 1mm thermal resistance number by the thickness of the whole floor covering. For successful infrared underfloor heating, make sure your final thermal resistance number does not exceed 0,15 m²K/W.
