CAN/ULC S701.1

The CAN/ULC S701.1 standard is a critical benchmark for factorymade, rigid expanded polystyrene (EPS) insulation boards used in construction. It ensures that EPS foam meets rigorous criteria for thermal performance, durability, and safety, making it an essential choice for builders and contractors.

Key Points
• Thermal Insulation: EPS foam must deliver reliable thermal resistance, retaining its R-value over time to ensure consistent performance.
• Moisture Resistance: EPS boards are required to have low water absorption, preserving their insulation properties and preventing degradation.
• Compressive Strength: EPS foam needs to withstand substantial loads without compromising its structural integrity, ensuring long-term reliability.
• Dimensional Stability: EPS boards should maintain their shape and size under diverse environmental conditions, providing consistent performance.
• Safety Standards: EPS foam must comply with stringent fire safety standards, ensuring it is safe for use in various construction applications.
