Product Description
Flame-Retardant & Commercial F/R Grade Foil-Scrim-Kraft (FSK) Facing
Product Description

The F/R grade Foil-Scrim-Kraft (FSK) facing is manufactured with flame-retardant treated Kraft paper (60 gsm) and a 3-way scrim structure. It serves as an effective facing and vapor retarder for duct wrap insulation, providing enhanced fire resistance. The material is also suitable for other applications that require a general-purpose vapor retarder, and performs well as a radiant barrier thanks to its low emissivity.

Facing Composition
Component Description
Aluminum Foil 7 micron
3-way Fiberglass Scrim 8 × 12 / 100mm
Adhesive Flame-Retardant
Kraft 60gsm
Typical Physical Properties
Physical Properties Value
Basis Weight (g/㎡) 85
WVTR (ng/N.s) 5.75
Tensile Strength - MD (N/25mm) 120
Tensile Strength - XD (N/25mm) 60
Burst Strength (N/c㎡) 30
Advantages
  • Excellent Fire Performance: The core material (Kraft paper) undergoes special flame-retardant treatment, making it resistant to ignition and effectively slowing the spread of flames.
  • Superior Strength and Durability: The integrated "3-way scrim" structure provides exceptional tear and puncture resistance.
  • Effective Moisture and Vapor Barrier Properties: The surface foil layer and heavy-duty 60gsm Kraft paper together form a robust barrier that effectively prevents water vapor penetration.
  • Outstanding Thermal Radiation Barrier Function: The bright foil surface features extremely low emissivity, efficiently reflecting the vast majority of radiant heat.

This material successfully integrates four key functions--fire safety (F/R), mechanical strength (Scrim), vapor sealing (Kraft), and thermal reflection (Foil)--into a single product, delivering a versatile and cost-effective composite solution.

Applications

1. HVAC Duct Insulation
Its excellent fire performance (F/R) directly meets building codes' fire safety requirements for duct systems, preventing the spread of flames through ducts.

2. Building Envelope Vapor Retarder
Widely used in walls, roofs, and other building envelope structures of commercial and industrial buildings as a general-purpose vapor retarder.

3. Pipe and Equipment Insulation
Suitable for insulating pipes, storage tanks, and large equipment in factories and industrial plants. Its composite functions integrate fire resistance, moisture protection, and thermal insulation, providing a comprehensive protective solution for industrial facilities.

Important Notes
  • Available Roll Width: 1.0m, 1.2m, 1.25m, 1.30m, 1.35m
  • Tolerance: Weight and Thickness: ±10%; Width: ±3mm; Length: Log Roll: ±0.3m, Jumbo Roll ±0.5%.
  • The products should be stored at room temperature, kept away from wet and heat source.
