Abstract –This review delves into the advancements of hybrid thermal insulation materials, emphasizing the integration of multiple components such as rockwool, ceramics, aerogels, and rockwool- vermicomposting blends. The combination of these materials is aimed at improving thermal efficiency, strengthening durability, and promoting environmentally friendly solutions in mechanical engineering. These materials are particularly useful in energy-efficient buildings and industrial systems. This review focuses on how they perform in terms of heat insulation, their strength, and their ability to withstand challenging environmental conditions like high humidity and extreme temperatures. At the same time, it addresses practical challenges such as the high cost of production, limited availability of raw materials, and their overall impact on the environment. It also suggests ways to make these materials more sustainable and cost-effective. By blending these materials, we can achieve better insulation, reduce energy use, and cut down greenhouse gas emissions, which translates into lower costs and a smaller environmental footprint. Overall, the findings show that these advanced materials have great potential to reduce energy usage in buildings and industrial operations. This makes them an important step toward creating more sustainable and energy-efficient practices in engineering.
