Abstract
A prefabricated heat-insulation panel has two hot water flow paths installed separately inside a panel, with primary and secondary connection parts provided in the panel and connected to a boiler or allowing hot water to circulate to adjacent panels. A polybutene layer with rosin as an activator is formed on the inner surface of the hot water supply pipe made of thermoplastic elastomer, and reduces the diameter and the length of the hot water supply pipes installed in the panel and the panel thickness and minimizes the boiler load.
