Insulation acts as a barrier to heat flow and is essential for keeping your home warm in winter and cool in summer. A well-insulated home minimizes energy bills by reducing the amount of work your HVAC system has to do.
How R-Value Works
The R-value measures how well building insulation can prevent the flow of heat into and out of the home. The higher the R-value, the greater the insulation performance. Adding more insulation increases the total R-value of the space.
