The main challenge was reinforcing and securing sections of the newly installed metal roof to ensure full structural stability before applying the insulation system. In addition, the drainage channel required a specialized waterproofing solution to eliminate potential leakage points and ensure the long-term performance of the insulation system.

The metal roof was fully prepared through cleaning, fastening, and riveting works to create a stable substrate for the insulation system. A high-performance Polyurethane Foam insulation system specifically designed for metal roofs was then applied, followed by a UV-resistant acrylic protective coating to enhance durability and weather resistance.

To provide additional protection in water-prone areas, the drainage channel was waterproofed using a polyester system reinforced with fiberglass mesh, ensuring long-term resistance against water infiltration.

The project successfully delivered a complete insulation system using Polyurethane Foam with an acrylic protective coating, providing high-performance thermal and waterproof insulation through a seamless, joint-free layer that minimizes heat transfer and prevents water leakage. The system can also contribute to energy savings of up to 30–40% in air-conditioned buildings, depending on operating conditions. Additionally, it offers long-term protection against UV rays and harsh weather conditions, reduces condensation, extends the service life of the metal roof, and minimizes future maintenance requirements.
