A81 radiant ceilings combine in a simple way the system functions required in an office, in order to guarantee acoustic and thermal comfort. Depending on the hydraulic connection to the hot / cold water network and the choice of the type of regulation, the A81 radiant ceilings act on the space as a system of self-regulating thermoactive building elements, identical to our powerful HPL hybrid module with a high irradiation, suitable for environments with high thermal load. The peculiarity of the A81 radiant ceilings is the variable positioning respect to the ceiling.
