What is R-Value, U-Value and how do they relate to insulation?
Insulation, simply put, is a quality of a substance to ‘resist’ transferring heat (or cold, basically energy) through it. In building construction high insulation is used to allow the internal environment temperature to maintain constant independently of external temperature changes. This not only makes the inside a more ‘pleasant’ place to live, it helps reduce heating and cooling costs by making it easier to keep at the same temperature; which in turn means your home is more ecologically friendly, as you are consuming less environmental resources.
