Atlas EnergyShield R6.5

Atlas EnergyShield with dimensions 4' X 8' X 1" has an R value of 9.6. This means that it provides thermal resistance to the flow of heat, with a higher R value indicating greater insulation capacity. In this case, the insulation is designed to reduce heat loss or gain through walls, roofs, or foundations in buildings, thereby improving energy efficiency and reducing energy costs.
