Aluminum Foil Insulation Description

The DFC-101A aluminum foil insulation is engineered for durability and high reflectivity. Its multi-layered construction ensures structural integrity and consistent performance:

Reflective Surfaces: Features two outer layers of pure aluminum foil to maximize radiant heat reflection.

Core Strength: Contains a central layer of thicker natural kraft paper for rigidity.

Reinforcement: The layers are securely bonded with polyethylene and reinforced with a 3-way fiberglass scrim to prevent tearing during installation.

Aluminum Reflective Insulation reduces heat transfer by reflecting radiant heat away from living and working spaces. Compared to conventional bulk insulations, reflective foil systems deliver high thermal performance with minimal thickness, making them ideal for tight spaces or lightweight building structures.

Features
- High Reflectivity for Better Temperature Control: Reflects up to 95% of radiant heat. Helps reduce cooling and heating loads throughout the year. Enhances energy efficiency in both warm and cold climates.
- Dual Function: Acts as an effective vapor barrier, reducing moisture migration. Helps prevent condensation inside walls, floors, and roofs.
- Reinforced Structure: 3-way fiberglass scrim. The reinforced design ensures the aluminum foil insulation is tough enough to handle installation stresses without tearing.
- Compact Design: Thin, flexible profile. Provides insulation without the bulk, making it ideal for tight spaces where traditional batts may not fit.
Applications

This double sided foil insulation is versatile and suitable for a wide range of building and HVAC applications:
- Roofing: Ideal for use as sarking and insulation under roofs to reduce heat penetration.
- Wall Systems: Effective behind cladding in external walls to manage heat and moisture.
- Flooring: Can be installed under timber floors to reduce drafts and heat loss.
- HVAC & Piping: When combined with glass-wool, rockwool, or foam, it serves as an excellent vapor barrier for air-conditioning ducts, pipes, and vessels.
