Is Reflectix better than fiberglass?

Reflectix can be used as wall cavity insulation—but tacking it to the centers of the studs in each cavity is a laborious process. Traditional fiberglass insulation is easier and faster, and it will insulate better. The key to using Reflectix properly is to understand how reflective insulation works in the first place.

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.

Which type of insulation is most effective?

Spray foam insulation is the most energy-efficient insulation to create an air barrier in the attic. Certain spray foams can expand up to 100 times its original size, so it fills all of the nooks and crannies in the attic.

Is reflective insulation effective?

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.

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.

Radiant Barrier versus Fiberglass Insulation Hot Box Test

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.

Can Reflectix break 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 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.

Does Reflectix still 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.

What is the best insulation for cold weather?

If you live in a particularly cold climate, consider going with loose-fill fiberglass insulation. This insulation material has a high R-Value range of R30 to R60, making it perfect for climate zones that come with high R-Value recommendations.

Is foam insulation better than fiberglass?

When it comes to which is best in the spray foam insulation vs. fiberglass debate, spray foam wins, hands down. If you're a DIY-er, you may be used to installing fiberglass insulation. But if you're looking for something that will last a lifetime, let a professional install spray foam.

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 good for attic?

As a huge source of energy loss in homes, the attic is a great place to start. And reflective or foil insulation (like radiant barrier) is a great material to use.

Can Reflectix be left exposed?

Note: For all applications, do not leave exposed duct or space where air can enter between the duct and the Reflectix®. needed repairs. Any worn wiring should be replaced.

Where is Reflectix insulation used?

Reflectix can be used as basement ceiling insulation when precisely stapled to the centers of the floor joists above. The product must be applied tightly, with room for airflow.

Which way do you install reflective insulation?

The foil insulation goes on top of the moisture barrier, followed by the roof covering. If you use bubble foil or rigid foam insulation, it also goes on top of the moisture barrier. Remember that there has to be an air space between the foil and the roofing.

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.

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.

Does Reflectix melt?

The following website states that Reflectix can withstand temps up to 180* F. I think it would melt if your water is boiling (212* F at sea level). Get a temp gage and find out how long you need to wait for the pot to reach the safety threshold of 180*.

Is Reflectix waterproof?

Reflectix Insulation is 100% waterproof, fire retardant, fungus & mold resistant, saves energy and is also UV reflective.

How do you stick Reflectix to windows?

After cutting to shape I taped the outside edges of the "Reflectix" with duct tape. The tape has helped to hold each piece of "Reflectix" in place for the last two years. I have found that the glue in "Velcro" tape will melt when applied to the glass in the hot summer sun.

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!

What is the R-value of reflective foil insulation?

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

What is the R-value of reflective 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.
