Insulated products are designed to reduce the transfer of heat, keeping items hot or cold for longer periods. Common examples include insulated water bottles, coolers, and thermal bags. These products often use materials like foam or vacuum-sealed layers to create a barrier against temperature changes. The effectiveness of insulated products is measured by their R-value, which indicates the material's resistance to heat flow. Higher R-values mean better insulation. These products are widely used in various settings, from outdoor activities to everyday kitchen use, helping to maintain the desired temperature of food and beverages.
