EcoFoil Single Bubble Insulation Roll
EcoFoil offers a lightweight, easy-to-handle reflective insulation roll with a 48″ width and 125′ length. The single bubble design helps to reduce radiant heat transfer, reflecting about 96% of radiant heat and providing a low-emissivity surface. It is designed for quick installation and is made in the USA. The product is non-toxic, fiber-free, and carries a Class 1 / Class A fire rating, making it suitable for various indoor applications.
Key features include a thickness around 1/8″, high heat reflectivity, and straightforward cutting with common tools. While it focuses on radiant heat reduction, it can be paired with other insulating materials to improve overall thermal performance in attics, walls, and crawl spaces.
INSULATION MARKETPLACE SmartSHIELD -3mm 48inx10ft
This foam-core, reflective-insulation roll uses a 3mm closed-cell polyethylene foam core sandwiched between highly reflective engineered foil on both sides. It offers a radiant barrier with a vapor barrier component, is easy to install and cut, and is lightweight yet durable. It reflects a significant portion of radiant energy, helping to keep spaces cooler in the summer and warmer in the winter.
Ideal for attic, wall, and crawl-space applications where a quick retrofit is desired without extensive installation effort. Its dual-sided foil construction provides a robust reflective surface and simple handling during installation.
INSULATION MARKETPLACE SmartSHIELD -5mm 16x50ft
This roll includes a 5mm foam core that delivers an R15 rating and combines insulation with a radiant, vapor, and sound barrier in one product. The white surface with foil backing provides a clean, integrates seamlessly into attic or crawl-space renovations. It’s designed to be easy to install and cut, and offers a durable barrier against heat transfer while maintaining indoor air quality.
The product emphasizes all-in-one performance: insulation, radiant barrier, vapor barrier, and sound dampening, reducing installation complexity in mixed-use spaces such as garages and living areas adjacent to heated spaces.
INSULATION MARKETPLACE SmartSHIELD -3mm 16inx10Ft
This compact roll provides an economical option for smaller spaces, featuring a 3mm closed-cell foam core and a foam-core, radiant barrier sandwich. It focuses on reflecting radiant energy while offering a vapor barrier to minimize condensation risks. It’s easy to install in tight spaces or small attic sections and can be used indoors or outdoors depending on project needs.
The product line emphasizes portability and quick retrofit, suitable for homeowners pursuing targeted radiant heat control without a full-scale renovation.
SmartFOIL 4ft x 125ft
SmartFOIL is an industrial-grade radiant barrier designed for attic and building-perimeter applications. The 4ft by 125ft roll covers up to 500 sq. ft. and is perforated to allow some breathability while maintaining a high radiant heat block of about 95%. It meets or exceeds ASTM C1313 standards and carries a Class A fire rating, with clear coatings to resist corrosion. This product is built for demanding environments where durability and effective radiant heat reduction are essential.
SmartSHIELD -3mm 16x50ft (Commercial Grade)
This commercial-grade foam-core radiant barrier combines a 3mm closed-cell core with premium aluminum foil on both sides. It is designed for industrial or large-scale installations where high reflectivity and barrier properties are required. The product emphasizes vapor barrier performance and ease of installation, with a focus on long-term durability in challenging environmental conditions.
Buying Guide: Key Purchase Considerations
- Purpose and climate: Choose products that emphasize radiant barrier performance in hot climates or attic spaces where heat transfer is prominent. In colder regions, combining radiant barriers with traditional insulation improves efficiency.
- Material composition: Foam-core reflective products provide robust barrier performance and vapor protection, while foil-only options excel at high reflectivity but may require additional vapor or air sealing considerations.
- Thickness and coverage: Consider depth and roll length to fit the intended space. Higher thickness generally improves barrier properties but may be harder to install in tight spaces.
- Fire rating and safety: Look for Class A/1 fire ratings and non-toxic materials when installing in living spaces, attics, or crawl spaces adjacent to occupied rooms.
- Installation practicality: Lightweight, easy-to-cut materials save time and labor. Pre-cut formats and DIY-friendly designs are beneficial for homeowners performing retrofits.
- Durability and moisture handling: Vapor barriers help manage humidity. Reflective foils stable in varying temperatures while resisting off-gassing or fiber shedding.
- Compatibility with existing insulation: Reflective barriers are typically used in conjunction with other insulation types; plan a layered approach to maximize overall R-value and energy savings.
- Compliance and certifications: Verify that products meet local building codes and industry standards for radiant barriers and fire safety.
Overall, these options provide varied approaches to reducing radiant heat transfer and complementing traditional cellulose or fiberglass insulation. For best results, assess your home layout, climate, and retrofit goals, then select a combination of barrier materials that aligns with energy-saving targets and installation capabilities.
