How much R value does Reflectix add?

Interior air films vary with the surface finish of the product (Reflective or White) and the heat flow direction. The values utilized in Reflectix® R-value calculations for Interior “Air Films” are as follows: Reflective side of product: R-4.55 Down • R-1.32 Up • R-1.70 Horizontal.

What is the R-value of reflective insulation?

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

How much does Reflectix insulate?

It's small, tidy, clean, and best of all, it offers thermal-blocking R-values of up to R-27. As it turns out, Reflectix is not a competitor to fiberglass. It's a different kind of insulation for different applications.

How much R-value does Radiant Barrier add?

Radiant barrier on its own has NO R-value; R-value is attributed to materials slowing conductive heat. AtticFoil™ works to block radiant heat (97%) coming in to the attic by stapling it to the rafters, but it has no R-value.

Does Reflectix keep heat in or out?

Reflectix is equally valuable for keeping cool on hot sunny days. The greatest source of heat when the sun is shining is the windows. The heat load can be so high that your air conditioner may be unable to cool your camper down to a pleasant temperature when the sun is beating on it.

The Reflectix Insulation Test

Is reflective insulation good for winter?

Radiant Barriers (Reflective Insulation)

Reflective, radiant-barrier insulation is usually made of aluminum foil with a variety of different backings, including plastic film and cardboard. This type of insulation is most effective in warmer climates, but can also be used for comfort and energy savings in cold weather.

How effective is reflective insulation?

Reflective insulation can block 95% of radiant heat and provides superior thermal performance. Reflective insulation reflects escaping heat back in the direction of your home's interior. By harnessing the loss it lowers your heating bills.

What insulation has 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.

Is reflective insulation better than fiberglass?

The U.S. Department of Energy reports that reflective insulation is the most effective at preventing downward heat flow, making it a better choice for roof insulation where keeping heat out is the most important factor.

Does Reflectix work when covered?

No, it is not efficient once you cover it. It needs an air gap between the reflective surface and the radiant heat source. If you cover it directly, the fabric will heat up accordingly and the reflectix is not a good choice to deal with conductive heat.

Can you double up Reflectix?

With multiple layers of product and airspaces between each layer, enhanced performance will be gained. 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).

What is the R-value of bubble foil 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 radiant barrier better than insulation?

But if you must decide between the two, there is likely a clear winner: the radiant barrier. It is more effective, will give you more energy savings, and will provide you with more reliable in-home comfort.

Is Reflectix really r21?

Reflectix is now offering a dramatically improved performance application for the crawl space. This R-21 application includes a double layer of the Reflectix® Reflective/Bubble product. Its ease of handling and installation makes it the obvious choice when looking at crawl space insulation options.

Does Reflectix work in attic?

Reflectix® products are an excellent, energy-efficient choice for upgrading your attic system. When installed properly, a reduction of up to 10% in the home's air conditioning usage can result. The products are clean, lightweight and easy to install.

Can Reflectix damage windows?

Reflectix is a great product when being used for it's intended use as a reflective insulation or radiant barrier. It is not intended for use in residential or RV windows. When used on the inside it can break any window whether it is single or double pane.

Is a radiant barrier worth the money?

Some studies show that radiant barriers can reduce cooling costs 5% to 10% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system. In cool climates, however, it's usually more cost-effective to install more thermal insulation than to add a radiant barrier.

Is silver foil insulation any good?

Foil is used in space-faring craft because of these great properties preventing radiant heat loss. Because space is a vacuum, there is very little heat lost by conduction, so foil is absolutely perfect.

Does radiant barrier affect WIFI?

With Wi-Fi signals, unless the radiant barrier is between you and the router, there is unlikely to be any impact.

Is Reflectix a vapor barrier?

The product provides a vapor/moisture barrier, which is a strong contributor to the efficiency of the system. Reflectix® is available in convenient roll sizes which contributes to ease of handling and installation.

Can I use reflective insulation with fiberglass insulation?

If you want to combine insulation types, using reflective insulation and fiberglass insulation in a wall space can boost the R-value by 3.9 points. By utilizing reflective insulation, an R-21 total wall assembly can be created, with a vapor and moisture barrier.

Is radiant barrier worth it in Texas?

The average temperature in Texas during the summer is between 86 and 98 degrees Fahrenheit. When combined with low rainfall levels and low humidity, 90-degree temperatures can feel unbearable. As part of a whole-attic system, radiant barriers can improve the comfort of your home.
