In a conventional thermal insulation roof system, the insulation is installed beneath the waterproofing membrane, providing effective protection against heat loss and ensuring the durability of the roof. This setup allows the waterproofing membrane to protect the structure from water infiltration while the thermal insulation layer offers temperature regulation, making the building more energy efficient. By keeping the roof surface cooler in the summer and warmer in the winter, the system contributes to reducing energy costs while maintaining comfort levels inside the building.
