Indoor air temperatures are generally limited to a range
between 17 and 28 C but floor heating can create exceptional
conditions in flooring materials (temperatures of 50e60 C). When
the temperature is increased, all the processes with a potential to
contribute to the emission of VOCs and formaldehyde, such as
diffusion within a flooring material, desorption, evaporation and
chemical reactions are increased. In conclusion, some wooden
flooring may contribute to the contamination of indoor air with the
use of floor heating
