Product Overview
What is VMPET+PE Insulation Film?
VMPET+PE insulation film is a composite material where a metalized PET layer is coated with a thin layer of polyethylene. The metallized PET layer reflects radiant heat, while the PE layer provides flexibility, waterproofing, and mechanical protection.
Key features include:
-
High reflectivity (up to 95%) for radiant heat.
-
Lightweight and flexible structure for easy installation.
-
Water-resistant and damp-proof properties.
-
Suitable for lamination with EPE, XPE, and other foam insulation materials.
Material Composition
-
Metalized PET (VMPET): Provides reflective and barrier properties, enhancing thermal insulation efficiency.
-
Polyethylene (PE) Coating: Adds flexibility, durability, and protects the metallized surface from moisture and mechanical damage.

Advantages of Reflective Metalized PET Film
1. Superior Thermal Reflection
The metalized layer efficiently reflects sunlight and radiant heat, reducing heat absorption in buildings. This improves energy efficiency and helps maintain consistent indoor temperatures in underfloor heating systems.
2. Waterproof and Moisture-Proof
The PE coating provides excellent resistance to water and humidity, preventing moisture penetration and protecting the underlying insulation materials, such as foam boards or bubble films.
3. Compatibility with Insulation Materials
VMPET+PE film can be laminated with woven fabrics, EPE/XPE foams, and bubble foils to enhance insulation performance. The film forms a strong barrier layer, increasing the durability and lifespan of the insulation system.
4. Dust and Dirt Protection
The film prevents dust and debris from entering the insulation layer, ensuring the integrity and efficiency of the thermal insulation over time.
5. Durability and Eco-Friendliness
Made from high-quality PET and PE materials, the film is durable, flexible, and environmentally safe. It can be recycled or reused in various applications.
6. Easy Installation
The lightweight and flexible design allows for quick installation on floors, walls, or ceilings. It can be cut to size, folded, or overlapped to ensure complete coverage without compromising performance.
