Hello!
This is from a text about laying parquet flooring over under-floor heating. Can anyone tell me what that big long word in the sentence below means? Also, am I right in thinking that the "qm" in "0,17 qm" is Quadratmeter, or is it something else entirely?
Many thanks!
Hilary.

Thermal resistance
That's the entry in Ernst.
qm = sq. meter (area)
K = Kelvin (or degrees Celsius if you prefer)
W = Watts (thermal power)
So it takes 1 watt of thermal power to heat up 0.17 square meters of this material one degree Celsius.

--------------------------------------------------
Another way of looking at it: If the temperature difference between the 2 sides of the material is 1 degree Celsius, then an area of material 0.17 sq. meters in size will allow 1 Watt of thermal power to be conducted through it.

Better yet: Thermal resistivity, since we\'re talking about a property of the material. Thermal resistance refers to a specific real application.

The same applies to Kelvin and Celsius. Kelvin refers to a unit of temperature and is used in a description of a property as is the case here, whereas Celsius refers to an actual measurement.

Forget what I wrote about it taking 1 Watt to \"heat up\" the material 1 degree. That was incorrect. The second way of looking at it is correct - steady state conditions with a temperature differential applied to the 2 sides. The thermal resistivity is the resistance of the material to the flow of heat energy from the side with higher temperature to the side with lower temperature. Measured in Joules of energy per second = Watts.

Hi, Johannes. I've got a terrible feeling we're both going to miss out on this one.

I just translated a EN>GER document about thermally conductive materials. Thermal conductivity (Wärmedurchlässigkeit/ -leitfähigkeit) and thermal resistance (Wärmewiderstand, Wärmedurchlasswiderstand) were frequent terms in similar context
