R Value Calculator | ROCKWOOL

An R-value is the resistance value of particular components in construction and includes materials such as plasterboard, brick or insulation. It tells you how well these components insulate against heat and is determined by thickness. Adding them all together gives you an understanding of how well the construction will stop the heat escaping.
