Radiant heating is today the most widely used heating system. Advantages over other systems of central heating are well known. In underfloor heating the air temperature at different levels of the living space are closest to ideal, which gives a feeling of comfort, despite the fact that the average temperature in the room is lower, compared to a room heated by radiators. Because of lesser thermal movement of air in the room, dust rises less and relative humidity is increased. Because the temperature of the heated water is lower, low-temperature boilers, solar systems or heat pumps are possible to use for heating.

The company Fragmat began with the production of system boards for underfloor heating under the brand name Stirotermal at the turn of the century and expanded its choice of boards over the years. Until now over 5 million m2 of different types of boards were installed in various European and other markets.

Today the radiant heating program Fragmat covers a wide range of system panels from our own production. Because we want to offer everything necessary for the implementation of radiant heating systems, we included also other components in the sales program.

Did you know?

Underfloor heating was already used by the Romans. Public baths - spas, where the Romans spent their free time, were heated with hot air, which was passed under the stone pavement and through clay pipes in the walls (hypocaustum). In this way even cold stone becomes pleasantly warm.

Reasons to buy

  • equal heat distribution from floor to ceiling, provision
  • no visible heating installations in the rooms
  • simple and quick assembly
  • energy losses during ventilation are lower than in rooms where radiators are installed under windows
  • lower heating costs, an average of 6 to 12 %
  • less lifting and circulation of dust in the room, due to the slow movement of the air
  • higher relative humidity respectively less dryness of air in living spaces
  • provision of a higher floor temperature, at an average of 20° C to 29° C
The brand FRAGMAT, a concept of quality and tradition.
