ARK-W20
Polyester/Scrim/Kraft – Thermally Stable Insulation Facing
ARK-W20 is a high-performance Polyester/Scrim/Kraft (PSK) insulation facing designed to provide durable thermal and moisture-control performance in residential and commercial building assemblies. Its multi-layer construction combines a specialty polyester surface, reinforced fiberglass scrim, and kraft backing to provide enhanced thermal stability, tear resistance, and reliable vapor-control performance.
Designed to maintain consistent performance across a wide temperature range, ARK-W20 provides a durable facing solution for insulation applications where thermal stability and mechanical strength are important. Lightweight and easy to handle, it is suitable for walls, ceilings, HVAC ducts, and other general insulation applications.
Key Advantages:
- Enhanced Thermal Stability – Specialty polyester construction is designed to provide reliable performance across demanding temperature conditions.
- Reinforced for Strength – Fiberglass scrim provides excellent tear resistance and helps maintain facing integrity during handling and installation.
- Reliable Vapor Control – Kraft backing provides consistent vapor-control performance where required by the insulation assembly.
- Improved Structural Stability – Multi-layer construction helps maintain dimensional and mechanical stability during installation and service.
- Lightweight & Easy to Handle – Designed for efficient handling, cutting, and installation.
- Versatile Applications – Suitable for walls, ceilings, HVAC ducts, and a variety of residential and commercial insulation systems.
Built for Thermal Stability.
Specialty polyester construction is designed to maintain reliable facing performance across a wide range of operating temperatures.
Reinforced With Fiberglass.
Fiberglass scrim adds strength and tear resistance, helping the facing withstand handling and installation demands.
Help Control Vapor.
The kraft backing provides vapor-control performance where a suitable vapor retarder is required within the insulation assembly.
Stay Stable During Installation.
The multi-layer construction provides structural stability to help maintain facing integrity during cutting, positioning, and installation.
Lightweight. Easy to Work With.
ARK-W20 is designed for efficient handling and installation, helping contractors work with less material-handling effort.
Built for Multiple Applications.
Suitable for walls, ceilings, HVAC ducts, and other residential and commercial insulation applications.
Performance Where It Matters.
ARK-W20 combines thermal stability, reinforcement, and vapor-control properties in one practical PSK insulation facing.
