DFR-101A
Double Sided Foil Insulation DFR-101A is a premium, flame-retardant (CM grade) thermal insulation material engineered for superior performance in construction. This double sided insulation expertly combines two reflective layers of aluminium foil insulation with an inner core of F/R kraft paper and Fiberglass. Its unique construction provides both outstanding thermal insulation and effective moisture barrier properties.
As a specialized double sided aluminium foil insulation, it is designed to reflect radiant heat in both directions. The highly reflective aluminum foil layers efficiently reflect radiant heat away from the insulated space, while the core insulation material provides additional thermal resistance, significantly reducing heat transfer through conduction and convection.
The Double Sided Foil Insulation is crafted with a unique multi-layer structure, providing superior thermal resistance and durability. It consists of:
Aluminum Foil Layers: Highly reflective and designed to reflect radiant heat in both directions.
Fiberglass Reinforcement: Provides additional strength and stability to the material.
Flame-Retardant Kraft Paper: Acts as a protective layer, contributing to its fire-resistant properties.
Flame-Retardant Adhesive: Used to bind layers together, enhancing safety and durability.
Reflective Heat Barrier: The double aluminum foil layers help reflect radiant heat, maintaining a comfortable temperature in both summer and winter.
Thermal Insulation: The fiberglass and kraft paper layers offer excellent thermal resistance, minimizing heat transfer through conduction and convection.
Vapor Barrier: The reflective foil can act as a vapor barrier, preventing moisture from penetrating the insulation and reducing the risk of mold and mildew.
Flame Retardant: Complies with fire safety standards, making it ideal for applications in fire-sensitive environments.
Energy Efficiency: Helps reduce energy loss by 5% to 10%, making it an economical choice for insulation needs.
Lightweight and Easy to Install: Its lightweight construction simplifies the installation process, reducing labor costs and time.
Double Sided Aluminum Foil Insulation is widely used in both residential and commercial building applications, including:
Roof Insulation (Sarking): Installed under roofs to keep interiors cooler in the summer and warmer in the winter.
Wall Insulation: Used behind cladding to enhance thermal performance and energy efficiency.
Floor Insulation: Applied under timber floors to provide moisture and thermal protection.
Duct Insulation: Ideal for air-conditioning ducts, pipes, and vessels.
Combined with Other Insulation: When combined with glass wool, rock wool, mineral wool, or foam insulation, it further enhances its efficiency as a vapor barrier and thermal reflective material.
