Exceptional Thermal and Fire Performance

ROK-ON™ XT Structural Insulated Sheathing (SIS) with a phenolic core offers several advantages due to its innovative design and material properties. Here are the key benefits:

1. Fire Resistance

• Phenolic cores are inherently fire-resistant, providing excellent performance under high-temperature conditions.  ASTM E 84 Class A  0 Flame / 35 Smoke for just the core.
• ROK-ON™ XT sheathing can enhance the fire rating of buildings, making it suitable for applications requiring strict fire safety compliance.

2. Thermal Insulation

• Structural insulated sheathing reduces thermal bridging and enhances the energy efficiency of buildings.
• Its phenolic core has excellent thermal performance, helping to maintain indoor comfort and lower energy costs.
• It is available with a 3” core (R-21) or 2” core (R-15) and can eliminate the requirement for cavity insulation or exceed “stretch” code mandates introduced in many states.
• Helps drive the dew point to the exterior of the wall assembly.

3. Structural Strength

• The sheathing offers added structural integrity, reducing the need for additional bracing or reinforcements in wall assemblies.

4. Durability

• Phenolic cores are resistant to moisture, mold, and rot, which improves the longevity of the material.
• The outer layers are typically durable against impacts and weathering, making it suitable for various environments.

5. Ease of Installation

• The product combines structural support and insulation in a single panel, streamlining the construction process.
• It can be used in various configurations, including walls, roofs, and floors, reducing the need for multiple materials.

6. Sustainability

• Phenolic-based insulation materials are often more environmentally friendly due to lower embodied energy and minimal VOC emissions.
• The integration of insulation and structural layers in one product can reduce waste during construction.

7. Compatibility

• The sheathing is compatible with other building systems and materials, making it versatile for use in different types of construction projects.

8. Acoustic Insulation

• It provides soundproofing benefits, making it a good choice for buildings where noise control is essential.

These advantages make ROK-ON™ XT Structural Insulated Sheathing with a phenolic core raises the bar as an excellent choice for modern, energy-efficient, and fire-safe construction.
