100% R-value Warranty

EnerSpan M-24 Insulation


EnerSpan® M-24 insulation 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.

EnerSpan M-24 insulation is 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 (see material properties
table).

• 100% R-value Warranty
• Closed-cell structure is moisture resistant to provide long-term durability
• Can be recycled or reused
• Adaptable and versatile
• Durable and resilient
• Does not support mold growth
• Easy to cut, saw or score
• Cost-effective
• Shiplap provided on all four edges of board
• Installation methods per local building code
