DPTF-1251
PET-Foil-PET Vapor Barrier Insulation is a high-performance insulation solution that combines durable PET film with an aluminum foil layer to create an effective vapor barrier. This versatile insulation material provides superior moisture resistance, preventing condensation and moisture-related issues. It is specifically designed for cold and cryogenic insulation systems.
Foil Vapor Barrier Insulation DPTF-1251 is a premium PET Aluminum Foil insulation composed of 12μ polyester film, 25μ aluminum foil, and 12μ polyester film. The PET foil vapor barrier is constructed for durability, moisture resistance, and excellent thermal performance. The aluminum foil layer acts as an efficient vapor barrier, preventing moisture from penetrating the insulation material and reducing condensation.
The PET film layers offer mechanical strength and flexibility, while the aluminum foil provides superior reflective insulation properties. This combination ensures an outstanding vapor barrier, making it an ideal material for use in outdoor and industrial insulation applications.
Superior Moisture Resistance: The aluminum foil layer acts as a strong vapor barrier to reduce moisture movement.
High Durability: The PET film layers ensure strength and flexibility for both indoor and outdoor applications.
Thermal Efficiency: Reflective aluminum foil enhances energy efficiency by reflecting radiant heat back into living or working spaces.
Easy to Install: Flexible, lightweight, and easy to handle during installation.
Versatile Use: Ideal for both residential and industrial insulation applications.
The PET-Foil-PET vapor barrier insulation is commonly used in:
Cold and Cryogenic Insulation Systems: Prevents moisture ingress in insulation, ensuring long-term efficiency.
Building and Construction: Ideal for installation in walls, roofs, and floors to enhance thermal insulation and energy efficiency.
Industrial and Commercial Applications: Suitable for use in temperature-sensitive environments where moisture control is critical.
This foil barrier insulation is typically installed with the foil layer facing the warm side of the building envelope. This positioning helps to reflect radiant heat back into the space, improving overall energy efficiency.
