What is the R-value of double bubble foil insulation?

The R-value of 3/8-inch-thick foil-faced expanded polystyrene foam is about 1.6. By contrast, 2 inches of extruded polystyrene insulation has an R-value of 10. Bubble-wrap manufacturers who claim their product matches the performance of 2 inches of rigid foam are breaking the law.

Does double bubble insulation have an R-value?

If the product is simply “doubled” (with no air space between the layers), a very minimal benefit is obtained (R-1.1 (per layer) for the Reflective/Double Bubble product).

Is Double bubble insulation any good?

The double bubble does assure that there's an isolated air pocket across the entire surface of the material; however, since the two layer of bubbles are pretty thin, it's not great insulation.

What is R-value of foil bubble insulation?

Most brands of foil-faced bubble wrap are only 3/8 inch thick or less, and have an R-value of only 1.0 or 1.1.

Is bubble wrap foil insulation any good?

Foil-faced bubble wrap is a radiant barrier. It's not insulation. A radiant barrier reduces heat transfer by radiation and has two excellent applications in homes. Insulation reduces heat transfer by conduction through solid materials.

Bubble Foil Scams - False Claims About 11 R-Value By Other Products

What is the R-value of dead air space?

We now know the experts were wrong. In theory, air is a good insulator, if it can be kept from moving. Dry, absolutely still air has an R-value of 3.6 per inch of air — as good as most insulation materials.

What is the R-value of foil paper?

According to ASHRAE, when just a little condensation is visible on aluminum foil, the emissivity can reach 0.2 to 0.3, which would decrease that R-value down to R-3.86.

Is foam or bubble wrap better?

Foam packaging is thinner than bubble rolls, which means you'll be able to fit more into your moving box (but don't be tempted to overpack your fragile items!). Foam rolls and pre-cut sheets are ideal for surface protection and cushioning of valuables.

Is bubble wrap a good insulator for pipes?

Prevent your pipes from bursting this winter by wrapping a sheet of bubble wrap around them. Tie the bubble wrap with some sort of string—the bubble wrap will help maintain the pipes' temperature and prevent freezing/bursting.

Which foil insulation is best?

Multifoil Insulation is More Sustainable Than Other Options

Multifoil insulation has even more efficient benefits than other insulation options on the market. SuperFOIL insulation is also better for the environment because it's made with 40% recycled materials and fully recyclable at the end of its life!

Is Double bubble insulation a vapor barrier?

Double Bubble White/Foil Reflective Insulation is 1/4" thick and is designed for walls, basements, crawl spaces, metal buildings and under slab radiant heating systems. Double Bubble White/Foil Reflective Insulation also serves as vapor barrier.

What is double bubble insulation used for?

Double Bubble Insulation - Our most popular bubble foil insulation is used for applications in metal buildings, pole barns, basements, crawl spaces, and many other places that require a vapor barrier.

Is foil bubble wrap a vapor barrier?

Bubble wrap insulation is made of one or two layers of foil with encapsulated air bubbles pressed in between the layers. It is a radiant barrier, which means it has the ability to reduce radiant heat, keeping your home, office, pole barn or warehouse cool and fresh in summer and comfortably warm in winter.

Is aluminum foil a good insulator?

Aluminum has an emissivity of around 0.04. That means it radiates very little heat away from its surface, which is one reason why radiators aren't made from aluminum! Aluminum foil can be an effective insulating material because it doesn't radiate heat out into the environment.

What is the R-value of rigid foam board?

Extruded polystyrene: Extruded polystyrene (XPS) rigid foam is usually blue or pink in color, with a smooth plastic surface. XPS panels typically aren't faced with other material. The R-value is about R-5.

Should I use foam and bubble wrap?

“Whether you choose to use bubble wrap packaging or foam packaging, both products offer superb protection. Bubble offers ease of use, economy, and effective protection, while foam offers characteristics that protect delicate surfaces and polished finishes, due to its ability to reduce scuffing, rubbing and marking.

Is bubble wrap durable?

When used properly, plastic bubble wrap is durable enough to last a cross-country trip. That means if you need to ship something from California to New York, bubble wrap has you covered. The air bubbles keep items suspended during shipping so they arrive at their destinations intact.

Does bubble wrap absorb force?

How it works: Bubble Wrap contains hundreds of small air pockets which are encased within layers of polyethylene. These bubbles of air suspend the product in the box, acting as a soft cushion barrier that absorbs shock in the event of unexpected movement and therefore prevents damage.

What R-value does reflective insulation have?

In short, reflective insulation can have an R value anywhere from R-3 all the way up to R-17.

How can I tell the R-value of my insulation?

Look under your floors.

Inspect and measure the thickness of any insulation you find there. It will most likely be a fiberglass batt, so multiply the thickness in inches by 3.2 to find out the R-value (or the R-value might be visible on a product label).

What is the highest R-value?

Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch.

What is the thinnest insulation with the highest R-value?

Aerogel insulation offers the highest R-value of any insulating material at less weight and thickness—ideal for construction, refineries, pipelines, and thin-gap thermal barriers.

What is the difference between pink and blue foam board?

Both are manufactured using the same process and contain similar chemical components. The two products also have the same insulating power. However, blue foam boards are manufactured by Dow Chemical Co. whereas the pink foam boards are manufactured by Owens Corning company.
