Reflective Aluminum Foil Insulation
Heavy-Duty, Premium-Grade Thermal Barrier
Double Sided Reflective Insulation, also known as Reflective Aluminum Foil Insulation, is an advanced energy-efficient insulation material designed to reflect radiant heat and improve thermal performance in residential, commercial, and industrial environments. It consists of two outer layers of pure aluminum foil and two layers of F/R Kraft paper bonded with flame-retardant glue and reinforced with a 2-way 5×5 mm fiberglass scrim for enhanced durability and heat resistance.
This advanced material uses pure aluminum foil insulation to create a powerful radiant barrier, significantly reducing heat transfer and offering potential energy savings of 5% to 10%. When you need versatile, long-lasting thermal protection, our Double Sided Reflective Insulation is the ideal choice for any building envelope.
Aluminum Foil Insulation Description
This reflective aluminum foil insulation provides superior thermal insulation and radiant barrier performance. Its double-sided design allows it to reflect radiant heat from both directions, maintaining stable indoor temperatures while reducing energy consumption. The high reflectivity of aluminum foil minimizes heat transfer, making it ideal for use in attics, walls, roofs, crawl spaces, garages, and sheds. Its integrated moisture barrier also prevents condensation, extending the lifespan of insulation systems.

Features
- Excellent Reflectivity: Reflects up to 97% of radiant heat, enhancing energy efficiency.
- Durable Construction: Reinforced fiberglass scrim provides exceptional tear resistance and long-lasting performance.
- Moisture Barrier: Prevents condensation and mold formation in insulation spaces.
- Fire-Resistant: Made with F/R Kraft paper and glue, suitable for demanding environments.
- Easy Installation: Lightweight and flexible, easy to cut and fit into various spaces.
- Non-Toxic & Safe: Eco-friendly materials suitable for residential and commercial applications.
-
Applications
This versatile reflective aluminum foil insulation can be used in a variety of applications to improve energy efficiency and comfort:
- Attics: Install under roof rafters or over attic floor joists to reflect heat radiating from the roof in summer and help maintain warmth in winter.
- Crawl Spaces: Apply to crawl space walls or the underside of the subfloor to reflect heat and improve comfort in the living space above.
- Garages and Sheds: Ideal for regulating temperature when installed on walls or ceilings, especially in extreme climates.
- Walls: Can be incorporated into wall assemblies or used behind wall cladding, though its use as a primary insulation source may be limited by building codes.
