Both side 0.12mm Black Gray Color Coated Aluminium Foil For Vapour Barrier

Introduction of Both side 0.12mm Black Gray Color Coated Aluminium Foil For Vapour Barrier

Double-sided 0.12mm black-gray coated aluminum foil, specifically designed for use as a vapor barrier in construction. Through a double-sided color coating process applied to the aluminum foil substrate, it combines the excellent barrier properties of aluminum foil with a specific appearance and functionality, making it an indispensable component in insulation systems.

Key Performance Features and Advantages

1. Excellent Vapor Barrier and Moisture-Proof Performance
Aluminum foil is an exceptional vapor barrier material, with a water vapor transmission rate that can be as low as virtually zero. The 0.12mm thickness ensures a dense, pinhole-free substrate that effectively prevents water vapor from penetrating the insulation layer, thereby avoiding condensation and a decline in thermal insulation performance, and extending the building’s service life.
2. Double-Sided Coating Design
Both sides are colored—one side black, the other gray. The black-gray option offers advantages in architectural applications such as roof moisture protection, including stain resistance, visual uniformity, and compatibility with a variety of architectural styles.
3. Thermal Radiation Reflection
The aluminum foil surface features high reflectivity and low emissivity, effectively reflecting radiant heat. When installed as a vapor barrier on the outer side of the insulation layer, it reduces heat loss and improves the building’s overall energy efficiency.
4. Enhanced Mechanical Strength
At 0.12 mm, this aluminum foil is of medium thickness. Compared to thinner foils, it offers higher tear and puncture resistance, providing better protection against external damage during installation and long-term use.

Typical Applications

This product is primarily used in building moisture-proof and vapor-barrier systems, specifically including:
Building Envelopes: Used as a moisture-proof and vapor-barrier layer for insulation in walls, roofs, and floors to protect insulation materials such as rock wool and glass wool from moisture damage.
Pipe and Equipment Insulation: Used as an outer protective layer for insulation on air conditioning ducts, HVAC piping, and industrial equipment.
Steel-Frame Buildings: Used as a moisture-proof and vapor-barrier layer for metal roofs and walls.
