Double Bubble Insulation - Foil/Foil - 6' x 125' (750 sq ft) (2023)

EcoFoil Double Bubble Foil Insulation is primarily used inpole barns,metal buildings,basement walls,crawl spaces, andstorage unitslocated in moderate and colder climates. Double bubble insulation combines the heat-shielding properties of solid radiant barrier with two layers of polyethylene bubbles, which acts as a built-in air gap that reduces contact between temperatures on either side of the product. Thedouble layer of bubbleseffectively combats the formation of frost and condensation that can occur when temperature differences are extreme on either side of the material.It's very thin (approximately 1/4"), lightweight, and installs easily with minimal equipment.

A radiant barrier and vapor barrier, all in one product

Not only does Double Bubble Insulationreflect radiant heat, when properlyinstalled with tapeit also acts as a vapor barrier, preventing the passage of moisture and other unwanted particles which can cause mold.In order to establish a vapor barrier, you must tapeall seams and jointsto prevent air passage, keeping moisture and other particles from passing through.

Radiant barriervs traditional insulation

Radiant barrier bubble insulation works differently compared to traditional insulation like fiberglass and spray foam.

• Traditional insulationworks toabsorbheat and is measured by R-value. The higher the R-value, the thicker the material and the more heat it can absorb.
• Radiant barrier bubble insulation, on the other hand,reflectsheat back to its source (whether that's your furnace or the sun.)

When used together, these two insulation types can provide a highly effective one-two punch that will keep your building warmer in the winter and cooler in the summer.

R-Value Of Radiant Barriers

Because these two insulation types have different purposes, their effectiveness is measured differently. Rather than rating by R-value, all radiant barrier products are measured by theirreflectiveandemissiveproperties.When installed properly with an air gap on one side of the product, double bubble insulation will reflect heat away from your building in the summer, and keep heat in during the winter.

There are some companies out there posting big R-Value numbers for their radiant barriers, but those numbers are rating the entirety of the system—including the product, air gap, and other building materials. In reality, most radiant barriers by themselves have little to no R-Value.If you need to satisfy a building code of a specified R-Value,we recommendthe use of a traditional insulation in conjunction with our radiant barrier in order to meet code.

Why choose a 6' roll?

EcoFoil Double Bubble Foil Insulation performs the same regardless of what size roll is used. A common reason for choosing our 750 sq. ft. roll is if it provides savings in installation cost or time to install. Because this roll is considered "over-sized", it makes it more expensive than our standard 4' roll. As a result, it is often more economical to go with the 500 sq. ft. roll in the same amount of square footage needed for an application. If you need assistance comparing the costs, or for a custom quote, please give us a call at (888) 349-3645 and we would be glad to help walk through this to ensure you get the product that is right for you.

EcoFoil Double Bubble Foil Insulation is not to be used under concrete slabs. For under concrete slab or radiant floor insulation applications, we recommendEcoFoil Under Slab Insulation.
