Aluminum Foil Vapor Barrier Description

 

This specialized vapor barrier is constructed from an F/R grade Foil-Scrim-Kraft Facing. It features an aluminum foil and Kraft paper outer layer, laminated with a flame-retardant adhesive to a middle layer of glass fiber. This robust construction increases tensile strength and creates a strong bond between the layers, ensuring a durable and tear-resistant material.

Features:

  • Superior Moisture Resistance: The material is specifically engineered to create an effective barrier against moisture transmission through walls, floors, and roofs.
  • Enhanced Thermal Performance: The reflective aluminum foil surface reflects radiant heat, which improves the overall energy efficiency of buildings.
  • Durability and Longevity: This vapor barrier is resistant to punctures, tears, and degradation, providing long-lasting protection against moisture infiltration.
  • Lightweight and Flexible: The material is easy to handle and can be effortlessly cut to size and shaped to conform to complex shapes and corners, ensuring complete coverage.
  • Broad Compatibility: Our aluminum foil vapor barrier is compatible with various insulation materials and building components, making it a versatile solution for a wide range of projects.

Applications:

The versatility and effectiveness of this vapor barrier make it essential for various applications across the construction and HVAC industries:

  • Building Construction: It is widely used to prevent moisture transmission through walls, floors, and roofs in residential, commercial, and industrial buildings.
  • HVAC Systems: As a critical component in HVAC systems, it prevents moisture migration into ductwork and insulation, helping to maintain thermal performance and prevent mold growth.
  • Attics and Crawl Spaces: Installing this barrier helps to control moisture and condensation in attics and crawl spaces, improving the building's overall energy efficiency.
  • Basements and Foundations: It is crucial for basement and foundation walls to prevent moisture infiltration and potential water damage, protecting against mold growth and structural issues.
