PlastiSpan Type 2 R10.1

PlastiSpan Type 2 rigid insulation is a type of expanded polystyrene (EPS) foam insulation that is designed to provide thermal insulation to buildings. It has a density of 1.35 pounds per cubic foot and a thermal resistance value (R-value) of 10.1 when it is 2-1/2 inches thick.

This means that it can resist the transfer of heat through a building assembly and help to reduce energy consumption for heating and cooling. The insulation is typically sold in sheets that measure 4 feet by 8 feet.
