Heat resistant Film+PE+PET Mesh Reflective Vapour Barrier for building insulation AL APR90

Heat resistant Film+PE+PET Mesh Reflective Vapour Barrier for building insulation AL APR90

Reinforced AL Film is a high-performance composite material composed of three layers of AL Film (aluminum foil), PE (polyethylene) and PET Mesh (polyester fiber mesh). The aluminum foil layer provides excellent barrier properties (moisture, oxidation and UV protection), the PE layer gives the material flexibility and sealing, and the PET mesh reinforcement layer significantly improves tear resistance and mechanical strength.

This product combines lightness and durability and is widely used in building insulation (roof/wall barriers), industrial packaging (moisture-proof pads), agricultural covering (greenhouse insulation) and electronic protection (electromagnetic shielding).

Heat resistant Film+PE+PET Mesh Reflective Vapour Barrier

Film + PE + PET Mesh · 3-layer Composite for Building Insulation

The Heat resistant Film+PE+PET Mesh Reflective Vapour Barrier is a three-layer composite engineered for building insulation applications where heat reflection, vapour control, and mechanical reinforcement are required. The material combines a heat-resistant film layer, a polyethylene core, and a PET mesh reinforcement, resulting in a mass per unit area of approximately 90 g/m². Tensile strength is specified at MD 280±40 N/50mm and CD 180±40 N/50mm, with elongation values of 20±20 N/50mm in both directions. Resistance to tearing (nail shank) is rated at MD 200 +20 N and CD 160 +20 N, providing defined puncture resistance. The film achieves a solar reflectance greater than 90%, contributing to radiative heat reduction. Water penetration resistance is classified as W1, and the product is available in standard dimensions of 1.5 x 50 m, with custom sizing and color options upon request. This vapour barrier is suitable for use in roof, wall, and floor insulation systems where thermal performance, moisture management, and durability are required.

Core Advantages

  • Three-layer construction with PET mesh reinforcement provides enhanced tear resistance (MD 200+20 N, CD 160+20 N) compared to standard film-only products.
  • Solar reflectance exceeding 90% contributes to reducing radiative heat gain, supporting energy efficiency in insulated building assemblies.
  • Heat-resistant film layer allows the barrier to maintain performance in elevated temperature environments typical of roof and wall insulation systems.
  • Lightweight at approximately 90 g/m², facilitating easy handling and installation while providing defined mechanical strength.

Application Scenarios

  • As a reflective vapour barrier in pitched roof insulation systems, placed between rafters or over ceiling joists.
  • For use in wall insulation cavities, behind cladding or drywall, where both vapour control and thermal reflection are required.
  • In floor insulation systems above unheated spaces, providing a moisture barrier with reflective properties.
  • Suitable for new construction, retrofit, and renovation projects requiring a lightweight, reflective, and vapour-resistant underlay.

Frequently Asked Questions

expand all
What is the function of the PET mesh layer in this vapour barrier?

The PET mesh layer provides mechanical reinforcement, significantly improving tear resistance (nail shank) to 200+20 N in MD and 160+20 N in CD. This reinforcement helps the barrier resist damage from fasteners, handling, and installation stresses, while maintaining flexibility and lightweight characteristics.

How does the heat-resistant film contribute to the product's performance?

The heat-resistant film layer allows the vapour barrier to maintain its structural and reflective properties at elevated temperatures commonly found in roof and wall insulation systems. This is particularly relevant in warm climates or in assemblies where the barrier is placed close to heat-generating elements.

Can this product be used as a standalone vapour barrier?

Yes, the product is designed as a vapour barrier with a water penetration resistance classification of W1. It provides a defined level of moisture protection and can be used as part of an insulation system where vapour control is required. However, for specific vapour permeability requirements, the SD value or equivalent should be verified with the supplier.

What custom options are available for this product?

Custom dimensions (other than 1.5 x 50 m) and custom colors are available on request. Lead times and minimum order quantities may apply. Please contact the supplier for specific customization requirements.
