Does Reflectix keep heat in or out?

They do a nice job of keeping out heat (and light) when in place.

Does reflective insulation keep heat in?

Unlike mass insulation, reflective insulation is able to keep heat in and reflect heat away. Mass insulation material like fiberglass and foam merely slow down the transfer of heat; they do not reflect heat away, nor do they keep heat in. Reflective insulation has the ability to control the transfer of radiant heat.

Which side of Reflectix faces out?

When it's hot out, we want to keep the heat out of the van. The window coverings are placed such that the Reflectix side is facing outward, to reflect the sun's rays. In the cold, with the Reflectix facing inward, it helps to keep heat trapped inside the van where we want it.

Does Reflectix work if you cover it with fabric?

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 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.”

DIY Reflectix window inserts! Keep heat in during winter, or out in summer!

What is Reflectix good for?

Reflectix lets you insulate spaces that might ordinarily go uninsulated because it would be prohibitive to insulate them with fiberglass. You might have a cold workshop with heat escaping through the roof. Stapling a layer of Reflectix along the rafters will cut down on some heat loss and stop air infiltration.

What can I put on my camper windows to keep the heat out?

Add blinds or curtains

Adding just about anything as a barrier between your RVs windows and your RV interior can help increase insulation. Blinds will help reduce the amount of UV light that enters the cabin, for cooler temperatures in the summertime. Heavy curtains can even help hold in heat during the winter months.

Will Reflectix damage RV 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.

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 reflective insulation any good?

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 radiant barrier need air space on both sides?

Typically we suggest you have an air gap between 1/2″ and 3/4″ for the radiant barrier to work. Air gaps larger than this work well too – they promote ventilation on the foil and help keep the air dry and the air temps lower. Insulation is technically a solid with a lot of air in it therefore, it is NOT an air gap.

How do you use Reflectix on ductwork?

Installation Instructions

Verify the circumference of the duct at the mid-point of a spacer strip. Cut the Reflectix® product to this length plus 1”. Wrap the product around the duct and securely tape the linear and circumference seams (overlapping 1”) with UL181 Tape (goal is an air-tight, snug seam seal).

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.

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.

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.
