EXPOL R-Value Calculator
Welcome to the EXPOL R-Value Calculator. An R-value is a rating which measures how well insulation can resist heat flow. 'R' stands for thermal resistance. The R-value depends on the type of material, its density and thickness. Tiny air particles trapped in the insulating material resist the movement of heat (and cold).
To see R-value of thickness choose thickness, then choose product, then choose thickness value, you will then get R-value.
To see thickness of the R-value choose R-value, then choose product, then choose R-value and it will give you the thickness of the product.
