Dow Styrofoam is an extruded polystyrene board with a closed cell structure which means it won’t absorb moisture.
The boards are designed with a tongue and grooved edge to ensure the boards lock together to prevent moisture passing through the joints where the tongue edge is up and the groove edge is facing down.
Dow Styrofoam XPS offers excellent long term R-values that per unit thickness are superior to most alternative common insulation products.
