Web24 de abr. de 2024 · What is R-Value? An insulating material’s resistance to conductive heat flow is measured by its thermal resistance or its “R-value.” Simply put, the higher the R-value, the greater the insulating effectiveness. WebR-value is a rating system used to grade insulation products and materials. It is a measurement of thermal resistance and how well the insulation prevents the flow of heat. The higher the R-value, the higher the resistance. But choosing the appropriate insulation with the correct R-value varies between projects, largely due to location and climate.
