“…The lowest value of thermal conductivity is galvanized with a thickness of 2,30 mm and the highest is galvanized without coating. The conductivity was sequentially (8,067 Kcal/mhr °C), (5,389 Kcal/mhr °C), (4,634 Kcal/mhr °C), (2,449 Kcal/ mhr °C). This result is also in accordance with the temperature drop test where the thicker the coating, the greater the temperature drop.…”

The increasingly widespread use of galvanized roofs certainly has an effect on the occupants in the room below. Among them is a hot room temperature. For that reason, it is necessary to make new discoveries in the field of composites of natural materials to overcome them because most natural materials, especially natural stone, have low thermal conductivity, which means they can inhibit heat propagation. This study sought to ascertain how much andesite natural stone powder, combined with epoxy, can lower the room temperature when it is layered on a galvanized roof. Different amounts of natural stone powder applied to a galvanized roof results in different thermal conductivities. The temperature readings were taken at a height of 20 cm above the roof, right at the bottom galvanic, as well as the temperature in the room below. Our results showed that adding andesite natural stone powder to the roof was able to lower the room temperature, and the thicker the composite layer in coating the galvanized roof, the lower the room temperature under the roof.

“…Addressing these challenges demands technological solutions, particularly in the form of roof coatings. Implementing coatings that effectively reduce roof temperatures, especially during summer, can be an effective strategy [16,17]. Coolroofing technology, characterized by high solar reflectance, has proven to be efficient in reducing cooling loads and improving the energy balance of buildings throughout the cooling season [15,[18][19][20][21][22].…”

The ability of a roof to absorb heat is crucial for maintaining temperature stability within a room. Therefore, natural material composite coatings utilization offers a viable option for modern roof development. This research investigates how using natural stone mixed with epoxy, and applied as a coating on a galvalume surface, influences thermal conductivity and reduces room temperature. Temperature measurements were collected around a small room with a composite-coated roof, utilizing different types of rock in the composition. Thermocouples were placed 20 cm above the roof's surface, attached to the roofing composite, positioned beneath the galvalume layer, and within the small room. The results demonstrate a reduction in thermal conductivity and room temperature when natural stone powder is added to the roof. Experiments using composite coatings with various stone types exhibit varying degrees of room temperature reduction. Consequently, this research concludes that the unique properties of natural stone can effectively lower the thermal conductivity of roofs and decrease room temperature.
