Thermal resistance doesn't only depend on the laminate flooring but on the whole installation: Underlay used and laminate flooring.

Any of the ranges of the laminated flooring is a good heat conductor.

For those installations on radiant heating, we recommend to use FINfloor Silent Underlay, especially developped to maximize the transmission and the homogeneous diffusion of the heat. And it is at the same time a good acoustic reducer.

Yes, as long as we use FINfloor Silent Underlay, the only one recommended by the manufacturer.
In order that a flooring and its underlay can be used with radiant heating, the whole must not have a thermic resistance > 0.15 (m2.K)/W.

The values obtained for the Silent Underlay and our flooring are 0.102 (m2.K)/W for the 7-mm base board (FINfloor Home and Exotic) and 0,127 (m2/K)/W for the 8-mm (FINfloor Comm and Country).
Also, it is necessary to respect the following installation instructions.

Subsoil humidity content:
It is very important to check the humidity content of the mineral sub-soils (concrete, gypsum grounds) of the existing, recently-installed and already covered floorings (ceramic tiles, natural stone, plastic, etc.)
The content of humidity of the sub-soils is checked by the magnesium humidity test or with an equipment that tests the relative humidity.
Maximum humidity contents accepted in mineral sub-soils:

Concrete master flooring..............< 2.0 % CM
Anhydrite gypsum flooring...................< 0.5 % CM
We should try to get a value of < 0,3 % CM

When the installation of the under-floor heating system (radiant) is finished
1º- At least 21 days after, the mortar should be dry and has a level of humidy of less than 1.5 % CM. If it was more, you would have to wait until getting this value.
2º- We start to heat it until getting a superficial temperature of 18 ºC that we will maintain for 3 days.
3º- We will leave the closed boxes of the material for 3 days in the place where they are going to be installed.
4º- We will proceed to the installation of the flooring, maintaining the temperature of the base floor at around 18ºC.
5º- When the installation is finished we will keep the same temperature for 3 days more.
6º- After this time, we will be able to increase the temperature gradually, 5 ºC each day. The temperature of the base floor (contact temperature) must not rise above 28ºC OR 65 W/m² if it is an electric system.

The use of big carpets can over-warm, which is bad for the laminate flooring.
The perfect temperature for the room is ± 20 ºC for the air and a relative humidity of 50-70 %. In very dry situations, it is recommended to use of a humidifier to increase the relative humidity.
The switching on and off of the heating must be made in a gradual way (5º C each time). NEVER IN A SHARP WAY in order not to damage the flooring.
We recommend not to lay the skirting until the sequence of warming and colling passes. This way it will be possible to check that the peripheral joint is the right one after the flooring has moved in different conditions .

Determining factors for laminate floorings:
Depending on the season of the year, laminate floorings are subject to the influence of climate and temperature.
Because of that, the acclimatation of the product prior to its instalation is of vital importance.
The bundles must be stored and aclimatize in rooms where the installation is going to be made at least in 48 hours.

The microclimate conditions of the room where the flooring is going to be installed must be maintained before and during at least 3 days after the end of the installation:
Temperature of the surface of the floor .........................................................at least 15ºC
Room temperature...................................................at least 18ºC
Relative humidity..........................................................maximum 75%
Attention has to be paid to make sure that the stored laminate flooring is not exposed to air currents and the bundles are not backed against walls during the acclimatation period. The best is that they are placed horizontally and away from the wall.
