This integrated system is specifically engineered for interior projects requiring enhanced mechanical strength and a superior vapor barrier without the complexity of traditional metal jacketing.

KEY PRODUCT FEATURES

The AG cladding transforms standard elastomeric insulation into a rugged, high-performance system for demanding environments.
 
  • Reinforced AG Facing: Composed of a 7µ aluminum foil, fire-retardant glue, and a 90gsm glass cloth for maximum puncture and tear resistance.
  • Superior Vapor Barrier: The AG layer significantly reduces water vapor transmission, extending the life of the insulation and preventing Corrosion Under Insulation (CUI).
  • Heat & Light Reflectivity: The bright aluminum finish reflects external radiant heat and light, improving the overall thermal efficiency of the system.
  • Faster Installation: The factory-applied cladding eliminates the need for field-applied jackets, reducing labor time and onsite errors.
  • Antimicrobial Protection: Inherits the core properties of K-FLEX® ST, featuring a closed-cell structure that is naturally resistant to mould, fungi, and bacteria.

TECHNICAL SPECIFICATIONS

  • Base Material: High-quality K-FLEX ST flexible elastomeric foam (FEF).
  • Cladding Composition: A high-performance laminate consisting of 7 micron Aluminum foil, specialized fire-retardant adhesive, and a 90gsm Glass Cloth reinforcement.
  • Temperature Range: Suitable for applications from -165C to +110C for Tubes and up to +85C for Sheets and Rolls.
  • Thermal Conductivity: Exceptional insulation performance with a lambda value of 0.033 W/(m K) or less at 0C.
  • Water Vapor Diffusion: Provides a high resistance to moisture ingress with a base rating of mu 10,000 or greater, further enhanced by the aluminum-glass vapor barrier.
  • Fire Classification: Achieves high safety ratings with Class 0 (BS 476 P6/7) and Euroclass certification for low smoke and flame spread.
  • Mechanical Strength: High tensile strength of 255 N/25mm, providing excellent resistance to tearing and puncture.
  • Surface Finish: Bright, reflective silver finish for improved aesthetic appeal and radiant heat reflection.
  • Permeability: Extremely low permeability, making it an ideal choice for preventing Corrosion Under Insulation (CUI).

APPLICATIONS AND BENEFITS

Ideal Environments:

  • Industrial plants and mechanical rooms.
  • Commercial HVAC ductwork and chilled water lines.
  • Food and beverage production areas (easy-to-wipe surface).
  • Cleanrooms and pharmaceutical facilities (fiber-free).

Why choose K-FLEX® ST AG?

  • Mechanical Durability: The glass cloth reinforcement provides a “hard shell” that protects against accidental impacts and surface abrasions.
  • Professional Finish: Delivers a clean, uniform look that is ideal for exposed installations in commercial buildings.
