How reflective is Reflectix?

The product consists of one 96% reflective layer of film bonded to two internal layers of heavy gauge polyethylene bubbles (total thickness 5/16”). A wide variety of widths and lengths are manufactured.

Why is Reflectix special?

Reflectix® Radiant Barrier reflects 96% of the radiant energy striking its surface, resulting in a in up to a 40% heat reduction through the ceiling. Reflectix® Radiant Barrier offers a competitively priced product. Great for year-round.

Does Reflectix work if you cover it?

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.

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.

Do you need an air gap with Reflectix?

Why are air spaces required (in every application)? For either a reflective insulation or a radiant barrier, an air space is required on the reflective side of the product. (Most Reflectix® products are reflective (shiny) on both sides.)

Does Reflectix Work?

How much of an air gap does Reflectix need?

This product specifically states on it in big red letters “R-8 WITH AIRSPACE” and “R-6.0 WITHOUT AIRSPACE.” The company's website says “The product provides an R-8.0 when installed with a 0.75” air gap between the duct and the insulation, and R-6.0 when installed direct to the duct without a spacer.”

How does a Reflectix work?

(Most Reflectix® products are reflective (shiny) on both sides.) The reflective insulation benefit is derived from the interaction of the highly-reflective surface with the air space. If the reflective surface is in contact with another building material, it becomes a conductor (transmitting the energy by conduction).

Does reflective insulation keep cold out?

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.

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.

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.

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.

Can you walk on Reflectix?

What makes reflectix perform is both the the foil reflecting heat and the bubble wrap creating an air gap. Walk on it and the bobbles will burst leaving just the foil and a lose of a good part of the insulating properties.

Is Reflectix an air 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.

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 bubble foil insulation any good?

(The bubble wrap layer is unnecessary, since it adds cost to the material without adding any useful thermal performance.) Since the main benefit from foil-faced bubble wrap is due to its radiant-barrier facing, the product is basically worthless unless it faces an air space.

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.

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 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.

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.

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.

Does Reflectix block sound?

Its main goal is to reflect energy, heat mostly. It's meant to insulate. BUT it also claims to be usable as an effective sound barrier! The company actually suggests wrapping RV generators in this to muffle the noise.

How thick is Reflectix?

Reflectix is a 5/16-Inch thick, seven layer, reflective insulation which is available in rolls of various widths and lengths. It is used extensively in both specialty and standard construction projects.
