A radiant system with multilayer pipes is a heating system that circulates warm water through a network of pipes laid beneath the floor surface. The pipes used are typically multilayer pipes, which combine the flexibility and corrosion resistance of plastic with the structural strength and low thermal expansion of an aluminum core. To support the pipe network and improve thermal efficiency, various types of boards are used beneath the piping system. Together, the combination of multilayer pipes and specialized boards ensures efficient, reliable, and long-lasting radiant heating performance in residential and commercial buildings.
