VEVOR Double Reflective Insulation Roll, Foam Core Radiant Barrier, 3.2 mm 48 in x 100 ft, Double-Sided Aluminum Foil EPE Foam Heat Reflective Shield, Thermal Insulation Roll for Window RV Roof

VEVOR Double Reflective Insulation Roll Spans 48 in x 100 ft for Maximum Coverage

The VEVOR double reflective insulation roll is 48 inches wide and 100 feet long, giving you 400 square feet of continuous thermal coverage from a single uncut roll. This large format eliminates seams in the middle of wide surfaces, such as garage doors, RV sidewalls, and residential roof decking. These seams can let heat in at joints, reducing the surface’s thermal performance.

The full 100-foot length makes this roll useful for insulating entire structures without always having to buy multiple rolls or deal with overlap joints. The 48-inch width covers standard structural bay spacings in one pass, reducing installation time and material waste for large-scale thermal barrier applications such as insulating a detached garage, a mobile RV roof, or a series of residential windows.

3.2mm EPE Foam Core with Double-Sided Aluminum Foil Blocks Heat Transfer Year-Round

This double reflective insulation roll is 3.2mm thick and has a high-density EPE foam core sandwiched between two layers of aluminum foil. It is made in a tri-layer configuration to address conductive, convective, and radiant heat transfer simultaneously. The foam core absorbs and spreads out any leftover heat that gets through the outer foil layers. It stops heat from building up in wall cavities and roof assemblies.

The double-sided aluminum foil design ensures the material works in both directions: it reflects sunlight in the summer and keeps heat inside in the winter. The 3.2mm build is better than single-sided radiant barriers, which only work in one direction during summer or winter, because it works all year round. It provides a consistent R-value contribution regardless of the application, whether it’s peak summer heat or freezing winter temperatures.

95%+ Solar Heat Reflectivity Achieved Through High-Density Aluminum Foil Coating

This double reflective insulation roll has outer layers of aluminum foil that reflect more than 95% of solar heat. It is one of the best-performing radiant barriers in the category. This reflectivity rating means that less than 5 BTUs of solar radiation get through the surface for every 100 BTUs that hit it. It greatly lowers the cooling load on HVAC systems during the hottest months of the year.

A high-density foil coating process helps maintain this high reflectivity by protecting the surface from long-term UV exposure, temperature changes, and physical contact during installation. The aluminum coating on this insulation roll maintains its thermal-mirror properties for years of use on roofs, windows, and RV panels that face the outside. It differs from lower-density foil barriers, which lose their reflectivity after one or two seasons.

Double Reflective Insulation Roll 3-in-1 Radiant Barrier + Insulation + Vapor Control in a Single 3.2mm Layer

This double-reflective insulation roll has three distinct building science functions in a single 3.2mm profile: radiant barrier performance, which blocks solar heat gain; bulk insulation resistance, which slows conductive heat flow; and vapor control, which prevents moisture from moving through walls and roofs. By combining all three functions, you may not need separate layers for the barrier, insulation, and vapor retarder in many applications. It saves money on materials and makes installation easier on every project.

The vapor control function is especially important in areas with high humidity and in RVs, where condensation in wall cavities can lead to mold growth, structural rot, and insulation damage over time. This roll creates a complete thermal and moisture management system in one step by adding vapor resistance directly to the reflective foil layers.

Tear & Puncture-Resistant Build Withstands Rooftop and Garage Door Installation

This insulation roll features an EPE foam core and aluminum foil layers designed to resist tearing, puncturing, scratching, and surface wear. These are all things that constantly happen when you staple things to the roof, fit garage door panels, or attach things to the outside of an RV. Installers can handle, cut, and fasten the roll without extra protective packaging thanks to its mechanical durability. This process can reduce the time needed to get ready on site.

In roof deck applications, puncture resistance is especially important because fasteners, roofing nails, and staples must go through the barrier without tearing or delaminating the sealed foil surface. The strong yet light construction makes the 100-foot roll easy to handle by one person, so there is no need for a crew to handle the material’s weight or keep it aligned over long structural runs.

DIY-Friendly Cutting & Folding Design Fits Windows, RVs, Roofs & Garage Doors

This double reflective insulation roll is easy to install yourself. You can cut the 3.2mm profile with regular utility knives or scissors, so it fits any window frame, curved RV surface, or garage door panel size without special tools or professional help. The edges stay clean and stable in size, and they don’t fray or delaminate.

When you’re done with a project or need to take a break, the roll folds up flat so it doesn’t take up much space in a garage, workshop, or RV storage bay. This fold-flat portability also lets you use it in multiple places. You can partially deploy the same roll at one site, re-fold it, transport it, and continue at a second site with minimal risk of damaging the unused part when handled carefully. It makes it a useful tool for contractors and DIY homeowners working on multiple insulation projects at once.

Lightweight Thermal Insulation Roll Meets RV, Residential & Commercial Standards

This thermal insulation roll can cover 400 square feet. Yet, it remains light enough to be installed on vertical surfaces, overhead roof decks, and the exterior of vehicles without adding weight to the structure or requiring stronger fastening systems. It has a low mass-per-square-foot ratio, making it ideal for RV roofs and sidewalls, where every extra pound of material reduces fuel efficiency and payload capacity.

Aluminum foil’s reflectivity, EPE foam’s insulation, and vapor control performance all meet the thermal barrier needs for residential window insulation, agricultural building envelopes, and commercial garage door applications. It means that a single standardized product can be used in a wide range of situations.
