KOMEX Polyethylene Film with 10mm Metalized Layer, 1.2m Width

The KOMEX polyethylene film with a 10mm metalized layer is a high-performance insulation material designed for professional construction and renovation applications. Measuring 1.2 meters in width and providing 30 square meters per package, this product combines the durability of polyethylene foam with the reflective properties of an integrated aluminum foil layer. It serves as an effective barrier against thermal loss and moisture, contributing to improved energy efficiency and a stable indoor climate in various building structures.

Advantages

This insulation film offers excellent thermal resistance due to its 10mm thickness and reflective metalized surface, which helps to redirect heat back into the living space. The material is lightweight yet robust, with a density of 25 kg/m³, making it easy to handle and install across large surface areas. Its dual-layer construction provides a reliable vapor barrier that prevents moisture accumulation, thereby protecting building elements from condensation and potential structural damage.

Suitable for

• Thermal insulation of walls, floors, and ceilings
• Vapor barrier installation in residential and commercial buildings
• Improving energy efficiency in renovation projects
• Underlayment for various flooring systems

When it may not be suitable

This product is not self-adhesive, which may require additional mounting materials such as specialized tapes or mechanical fasteners for installation. It is not intended for use in high-temperature environments where the polyethylene foam structure could be compromised.

Key specifications

• Material: Polyethylene foam with aluminum foil
• Width: 1.2 meters
• Length: 25 meters
• Thickness: 10 mm
• Thermal conductivity coefficient: 0.392 W/(m·K)
• Density: 25 kg/m³
• Total coverage: 30 m²

How to use

Before installation, ensure that the surface is clean, dry, and free of debris. Unroll the film and cut it to the required dimensions using a utility knife. Position the material with the metalized side facing the heat source to maximize thermal reflection. Secure the edges using appropriate construction tape or staples, ensuring that all joints are tightly sealed to maintain the integrity of the vapor barrier. Avoid overlapping the material excessively to prevent uneven surfaces.

What to consider before purchase

• Verify the required total area to ensure sufficient coverage for your project.
• Confirm that you have the necessary mounting accessories, as the film is not self-adhesive.
• Check the orientation of the metalized layer relative to your specific insulation needs.

Usage recommendations

For optimal performance, ensure that all seams are sealed with high-quality aluminum tape to prevent air leakage and moisture penetration. Always store the rolls in a dry, shaded area away from direct sunlight until the moment of installation.
