ROCKWOOL Comfortboard® 110 is a rigid, high-density stone wool insulation board engineered for superior exterior continuous insulation performance in commercial building applications. This noncombustible insulation creates high-performance wall assemblies that improve energy efficiency and fire resilience.

• Thermally Efficient: R-4 per inch reduces thermal bridging and improves building envelope performance
• Fire Safe: Noncombustible stone wool with Class A fire rating (0 flame spread, 0 smoke developed)
• Moisture Management: Vapor permeable design allows moisture to escape while resisting water absorption
• High Density: 11 lbs/ft³ density provides rigidity and durability for heavy cladding systems
• Compatible Installation: Works with screw-through supported cladding systems
• Mold Resistant: Stone wool material naturally resists mold growth and corrosion

Technical Specifications:

• Dimensions: 1" x 24" x 48"
• R-Value: 4.0 hr·ft²·°F/Btu per inch
• Density: 11 lbs/ft³
• Compressive Resistance: 584 psf at 10% compression
• Water Vapor Transmission: 35 perm

Meets ASTM C612 Type IVA and CAN/ULC S702 Type 1 standards. Ideal for commercial exterior wall assemblies requiring continuous insulation performance.
