VEVOR Double Reflective Insulation Roll, Perforated Woven Fabric Radiant Barrier, 0.15mm 48 in x 250 ft, Double-Sided Aluminum Foil Heat Reflective Shield, Thermal Insulation Roll for Window RV Roof

≥95% Reflectivity with Double Sided Aluminum Foil Insulation Performance

This VEVOR double sided aluminum foil insulation achieves ≥95% thermal reflectivity through high-density aluminum foil coating on both surfaces. The two-layer aluminum design prevents heat transfer by conduction and convection while reflecting radiant energy away from surfaces. The 0.15 mm thickness is the best compromise between effective reflection and mounting versatility.

The ≥95% reflectivity rating is 20–30% higher than normal single-layer options. This saves energy by lowering cooling costs in the summer and keeping heat in during the winter. In temperatures ranging from -40°F to 180°F, this reflective efficiency maintains performance, making it ideal for year-round thermal management in both residential and business settings.

Advanced 0.15mm Perforated Woven Fabric Construction with Breathable Design

The engineered perforated structure allows controlled passage of air and moisture while maintaining thermal barrier properties. This prevents water from accumulating, which would make the insulation less effective. Along its length, the core of the PE woven cloth is 120N strong, and across its width, it is 100N strong. For long-term use, this makes it less likely to tear or get holes during fitting. For best airflow, each hole is 2 to 3 mm in diameter and well spaced. 

Together, the aluminum foil outer layers and polyethylene reinforcements in the woven fabric construction keep the structure's integrity under stress. The perforated design prevents moisture from being trapped, which can cause mold, mildew, and material degradation in non-breathable barriers. This ability to let air pass through the material makes it last longer while maintaining consistent temperature performance, even as humidity changes.

Massive 48" x 250ft Coverage Provides 1,000 Square Feet Application Area

The generous 48-inch width reduces installation seams while the 250-foot length covers up to 1,000 square feet in one roll, reducing waste and work time. Standard framing spacing is 16" to 24" on center, and the 4-foot width makes it easy to place between joists, studs, and rafters. The roll's 26-pound weight provides ample coverage while still being easy for one person to place.

Numerous roll connections, which cause thermal bridges and lower system efficiency, are absent because the length is continuous. Each roll has enough material to cover an entire room, insulate a garage door, or do a lot of work in an attic without having to buy more. The small storage space makes it easy to move and handle on the work site.

Multi-Layer Construction with Double Sided Aluminum Foil Insulation Technology

The aluminum foil on the outside is glued to the PE woven-fabric core using a heat-activated adhesive, forming a three-layer laminated structure. This construction method creates permanent bonds that prevent delamination under temperature cycling. The aluminum layers provide 99.9% pure aluminum content for maximum reflectivity.

The woven fabric layer in the middle distributes mechanical loads across the entire surface, preventing tears in high-stress areas or at fastener locations. When installed, the heat-sealed edges prevent leaks and keep out moisture. This multi-layer method provides the benefits of both a reflective thermal barrier and mechanical support in a single product.

Versatile Installation for Windows, Roofs, Walls, and Automotive Applications

This flexible double sided aluminum foil insulation handles curved surfaces, odd shapes, and complex geometries common in RV installations, car applications, and home retrofits. The shape makes it easy to cut, so you do not need any special tools to fit it precisely around obstacles like electrical boxes and plumbing holes. Standard utility knives make clean cuts that do not tear or separate at the edges.

Customizable sizes that keep visibility while protecting against heat are helpful for window users. When installing a garage door, the 48-inch width is enough to fit standard door panels. Attic and wall cavity applications take advantage of the material's ability to mold to uneven areas while maintaining its thermal performance. 

Temperature-Resistant Performance from -40°F to 180°F Operating Range

The double sided aluminum foil insulation construction retains its reflective properties even when temperatures fluctuate widely, without losing effectiveness. Withstands freeze-thaw cycles and does not become weak at low temperatures thanks to its PE woven core. High-temperature performance reaches 180°F under continuous exposure without adhesive failure or material degradation.

Thermal stability ensures the system works the same way in attic setups where it reaches over 140°F in the summer and is below freezing in the winter. Automotive applications benefit from engine compartment compatibility and underhood temperature resistance. 

Professional-Grade Durability with Tear and Puncture Resistance

The woven fabric support helps prevent tears from spreading, so small holes do not get bigger and cause the fabric to fail. The 120N longitudinal and 100N transverse strengths measured in the lab exceed the building code requirements for vapor shields. The resistance to scratches and wear keeps the surface in good shape during installation and service life.

The resistance to punctures can withstand the normal stresses of installation, such as using staples, mechanical fasteners, and contact with rough surfaces. A little damage to the material does not affect how well it works; it just keeps working. 

Space-Efficient Storage with Foldable Design for Easy Transportation

The flexible construction lets you fold it up small for storage and transport without compromising performance or leaving it permanently creased. The roll form arranges the unrolling in a planned way during installation, avoiding tangling and waste. Cutting up leftovers for projects that need them makes them easier to store or use later.

Single-person handling and installation are possible because the total weight of 26 pounds is very light and the dimensions are small. Moving vehicles require very little cargo space, and the roll format helps prevent cargo damage during transport.
