Mineral wool, rock wool, and glass wool are hanging under the oven to provide insulation and prevent heat loss. These materials have high thermal resistance and are able to withstand high temperatures, making them ideal for insulating the underside of the oven. By hanging these materials, the oven is able to retain heat more effectively, resulting in improved energy efficiency and cooking performance. Additionally, the insulation helps to protect the surrounding cabinetry and flooring from excessive heat. **

It is difficult to determine whether it is rock or glass wool without further information or a closer inspection. Both rock wool and glass wool are types of insulation materials that are made from different raw materials and have slightly different properties. Rock wool is made from volcanic rock, while glass wool is made from recycled glass. The best way to determine which type of insulation it is would be to consult the manufacturer's specifications or conduct a physical examination of the material. **

Rock wool is the best insulator for keeping out the cold. It has a higher R-value, which measures the material's resistance to heat flow, compared to glass wool and Styrofoam. Rock wool is also more resistant to moisture and fire, making it a more durable and effective option for insulating against the cold. Additionally, rock wool is made from natural and recycled materials, making it a more environmentally friendly choice compared to Styrofoam. **
