EnerSpan HD Insulation


EnerSpan® HD is a moulded expanded polystyrene (EPS) insulation with a
silver- gray colour manufactured to meet CAN/ULC-S701, Standard for
Thermal Insulation, Polystyrene, Boards and Pipe Covering. The insulation
boards are manufactured using Neopor® provided by BASF, a
graphite-enhanced raw material that reduces radiation heat transfer
resulting in higher thermal resistance (R-value) compared to standard
CAN/ULC-S701, Type 2 EPS insulation.

Continuous Insulation product contains:

• Exterior Insulation Sheathing
• Foundation Insulation
• Under Slab Insulation
