VEVOR Reflective Insulation Roll, Double-Layer Air Bubble Radiant Barrier, 6mm 48 in x 100 ft, Aluminum Foil White PE Film Heat Reflective Shield, Thermal Insulation Roll for Garage Door Window RV Roofs

VEVOR Radiant Barrier Foil Insulation Covers 48 in x 100 ft in One Seamless Roll

The VEVOR radiant barrier foil insulation comes in a single roll measuring 48 inches wide by 100 feet long. It covers 400 square feet without seams in the middle, so there are none in wide garage door panels, RV rooftops, or residential roof decking. In radiant barrier applications, coverage without seams is very important because every joint is a thermal bypass point through which solar heat can enter the building, lowering the system’s overall R-value.

The 100-foot continuous length makes it easy to insulate entire buildings, both residential and commercial, without having to buy multiple rolls or plan complicated overlaps. This roll is 48 inches wide, which aligns with many common structural bay spacings. It means installers can staple or tape a single strip across an entire wall or roof section in one pass, reducing labor time and improving thermal continuity across every square foot of coverage.

6mm Four-Layer Build with Foil + Double Air Bubble + White PE Film to Blocks Heat Transfer

This foil insulation is 6mm thick. It has four layers: an outer layer of aluminum foil that reflects radiant heat, a double-layer air-bubble core, and an inner layer of milky-white PE film. The aluminum foil reflects incoming solar radiation, the dual air bubble chambers trap and dissipate residual heat through thermal resistance, and the PE film provides a clean surface that resists moisture, light mechanical abrasion, and other environmental factors.

The 6mm profile is thicker than many 3 mm single-bubble radiant barriers. It doubles the amount of air trapped in the core, making the entire structure more heat-resistant. This extra layer of insulation is especially useful in places with very hot weather, such as metal building roofs, unventilated garage spaces, and RV rooftops, where surface temperatures can exceed 150°F and single-layer barriers struggle to keep heat from moving into occupied spaces below.

95%+ Solar Reflectivity from High-Density Aluminum Foil Coating Reduces Cooling Load

The outer layer of aluminum foil on this radiant barrier foil insulation reflects more than 95% of solar heat. It is done by applying a high-quality foil layer that maintains a uniform reflective surface across the full 48-inch width and 100-foot length of each roll. With a reflectivity of 95% or higher, less than 5 BTUs of the 100 BTUs of incident solar radiation on the barrier surface pass through.

This high-density foil coating maintains its reflective properties even after prolonged exposure to UV light, extreme heat and cold, and scratches and cuts during installation. The aluminum coating on this roll is designed to maintain its high reflectivity for years of typical use, unlike economy-grade foil barriers, which oxidize and lose reflectivity after one to two seasons.

3-in-1 Radiant Barrier + Insulation + Vapor Control Replaces 3 Separate Products

This roll of reflective insulation combines radiant barrier performance, additional thermal resistance, and vapor control into a single 6mm layer. It means that you only need to buy and install one product instead of three. The radiant barrier prevents solar heat from entering, the double air bubble core prevents conductive heat transfer, and the aluminum foil layers prevent vapor from moving through walls and roofs.

Vapor control integration is very important in areas with high humidity and in RVs that are closed off, because moisture entering wall cavities can contribute to mold growth, structural damage, and reduced insulation performance over time. This roll has vapor resistance built right into the foil layers, so you don’t have to install a separate polyethylene vapor retarder.

Tear & Puncture-Resistant 6mm Shell Handles Stapling, Roofing & RV Fastening

This radiant barrier foil insulation is made of four layers designed to withstand tearing, puncturing, scratching, and surface wear in high-stress situations, such as stapling to a roof, mounting a garage door panel, or fastening on RV walls and roofs. The 6mm thickness makes it much more resistant to damage than thinner single-layer foil products.

This durability is critical for roof deck applications because the barrier needs to withstand the installation process and years of thermal expansion cycling, wind loading, and foot traffic during maintenance. The 100-foot roll is easy for one person to handle because it is light. It means that you don’t need a crew to install it overhead, and it will stay strong enough for long-term use in permanent building envelope applications.

DIY-Cut Design Fits Garage Doors, Windows, RVs & Bungalow Roofs Without Tools

You can easily cut this aluminum foil radiant barrier with regular utility knives or household scissors. It lets you make it fit perfectly for garage door panels that aren’t standard sizes, window frames that aren’t straight, curved RV roofs, and angled bungalow roofs, all without specialized cutting tools or professional fitting equipment. The 6mm composite layers cut cleanly along the line without fraying, delaminating, or leaving unsealed foam edges, which reduces the effectiveness of the foil surface.

When you use only part of the roll, it folds flat, making it easy to store on a garage shelf, in a workshop cabinet, or in an RV storage compartment. It keeps the unused part safe from dust and damage between installation sessions. This fold-flat portability also makes it easier to work on projects at multiple sites.

Radiant Barrier Foil Insulation Lightweight Thermal Roll Rated for Residential, RV, Commercial & Agricultural Use

This radiant barrier foil insulation provides 400 square feet of four-layer thermal protection while remaining lightweight per roll. This feature means it can be installed on overhead roof decks, vertical walls, and RV rooftops without adding structural load or needing reinforced fastening schedules. The low mass-to-coverage ratio is especially useful for RVs because extra weight on the vehicle affects how much it can carry and how efficiently it uses fuel on long trips.

With 95%+ reflectivity, 6mm insulation depth, and built-in vapor control, this product meets the thermal barrier performance standards for residential windows, agricultural metal buildings, commercial garage doors, and mobile vehicle roofing. It can be used for many common insulation applications from a single standard roll.
