Aluminum Foil Insulation Description

Double Sided Aluminum Foil Insulation DEC-201A is engineered to deliver robust thermal protection and moisture resistance. Its multi-layer construction - foil/kraft/foil laminated with polyethylene - creates a strong, tear-resistant structure suitable for both new construction and retrofit projects.

This reflective insulation is ideal for pairing with glass wool, rock wool, mineral wool, and foam insulation, enhancing the overall thermal performance of the building envelope while functioning as an effective vapor barrier.

Features
- High Reflectivity: Two outer layers of pure aluminum foil. Reduces radiant heat gain/loss, lowering heating or cooling costs by 5% to 10%.
- Reinforced Durability: Integrated 3-way fiberglass scrim. Provides excellent tear resistance and durability during installation and throughout the product’s long service life.
- Vapor Barrier Function: Impervious film construction. Excellent as a vapor barrier, preventing condensation and protecting integrated insulation (like glass-wool or rockwool) from moisture damage.
- Consistent Temperature: Acts as a high-performance reflective insulation. Helps maintain a consistent indoor temperature year-round by stabilizing the thermal conditions within the building.
Applications

The Double Sided Aluminum Foil Insulation is a versatile solution for thermal control and moisture management in various building elements:
- Roofs and Ceilings: Used as sarking and insulation beneath the roof structure to reduce heat transfer into the building envelope.
- Walls: Installed behind cladding in external walls to enhance thermal performance.
- Floors: Applied under timber floors for added thermal protection and moisture control.
- HVAC Systems: When combined with standard insulation (mineral wool, foam), it is an excellent vapor barrier for air-conditioning ducts, pipes, and vessels to prevent condensation.

FAQ:

Q1: How does Double Sided Aluminum Foil Insulation reduce energy loss?
A: This reflective aluminum foil insulation primarily reduces heat loss or gain through radiation. The pure aluminum surfaces reflect up to 97% of radiant heat striking them, minimizing the heat transferred into your building in summer and out of your building in winter.

Q2: Is this reflective insulation suitable for commercial building standards?
A: Yes, the DEC-201A is rated as a medium-duty, housing-grade reflective insulation suitable for both residential and commercial building applications where compliance with relevant sarking and vapor barrier standards is required.

Q3: What makes this a "double-sided reinforced aluminium foil"?
A: It is double-sided because it features reflective aluminum foil on both exterior faces. It is reinforced due to the internal 3-way fiberglass scrim, which significantly increases its strength, making it durable for handling and installation.

Q4: Can I use this product as a standalone vapor barrier?
A: Absolutely. Due to its construction and polymer bonding, Double Sided Aluminum Foil Insulation is designed to function excellently as a standalone vapor barrier for moisture-sensitive areas like walls and air-conditioning systems.

Q5. Can this insulation be used with other materials?
A: Yes. It is often combined with glass wool, mineral wool, rock wool, and foam insulation to enhance overall thermal performance.
