Reflectix In Camper Vans: Does It Really Work?

Reflectix is a popular material used for insulation in camper vans. However, there is much debate about whether it is effective and how it should be used. Some people argue that Reflectix is a terrible insulator and will create a microclimate that will rust your van faster. Others claim that it is an effective radiant barrier, reflecting heat in or out as long as there is an air gap between the Reflectix and the van wall. The correct use of Reflectix in camper vans depends on the specific climate and conditions in which the van will be used.

Reflectix works best with an air gap

Reflectix is a popular choice for insulating camper vans, but it is often used incorrectly. Reflectix is a radiant barrier, which means it is very effective at reflecting radiant heat. However, this property is lost if something is placed directly on top of it. Therefore, when using Reflectix for insulation, it is essential to maintain a minimum air gap between the Reflectix and any other surface. This allows the Reflectix to function as intended and prevents the formation of condensation, mould, and rust.

There are several ways to achieve the necessary air gap when installing Reflectix in a camper van. One method is to use furring strips, which are thin slats of wood, to create a separation between the Reflectix and the wall. The Reflectix can be placed against the metal wall, with furring strips over it, and then panelling on top of the furring strips. Alternatively, the furring strips can be attached to the metal wall first, followed by the Reflectix and then the panelling. As long as there is an air gap between the Reflectix and the wall or panelling, the Reflectix will function effectively.

Another option is to leave the Reflectix exposed by dispensing with the furring strips and panelling. In this case, the interior of the van becomes the air gap. However, this may not be a practical solution, especially if space is limited. In such cases, other insulation materials such as straight foam insulation, wool, fibreglass batting, or cellulose may be more suitable.

While Reflectix is not the best choice for insulating the walls, floor, or ceiling of a camper van due to the need for an air gap, it excels as a window covering. Reflectix can be easily cut to size and placed in the window frame, creating a barrier that blocks radiant heat transfer. It is effective in both hot and cold climates, reflecting sunlight away from the van in the summer and trapping heat inside during the winter. When used as a window covering, Reflectix also provides privacy and can be easily removed when not needed.

In conclusion, Reflectix can be an effective insulation solution for camper vans, but it works best when used in combination with an air gap. This air gap ensures that the Reflectix can reflect radiant heat properly and prevents issues such as condensation and rust. By using furring strips or leaving the Reflectix exposed, van owners can create the necessary separation between the Reflectix and surrounding surfaces, optimising the insulation properties of Reflectix.

Reflectix is a good window covering

Reflectix is also a good window covering as it is stiff, which makes fitting it into the window and having it stay there much easier. Additionally, as it is non-porous, it provides a good air barrier, forming a pocket of air between the glass and the Reflectix that helps with insulation. This is particularly useful in cold temperatures as it keeps the heat inside the van. For example, one user reported that their window was "literally freezing" on the side without Reflectix, whereas the Reflectix was "not cold" on the inside.

Another advantage of Reflectix as a window covering is that it can be used in both hot and cold temperatures. In the summer, the reflective side of the Reflectix should face outwards to reflect the sun's heat. In the winter, the reflective side should face inwards to reflect the heat from inside the van back into the vehicle. This can be achieved by either having two sets of window coverings, or by having reversible coverings that can be flipped depending on the season.

Finally, Reflectix is a good window covering as it is relatively cheap and easily available. For example, one user suggests that bubble wrap, which can be bought cheaply and in thicker sizes, holds more air than Reflectix and therefore may be even more effective at insulating. Therefore, Reflectix is a good option for those on a budget who are looking for a simple, effective way to insulate their camper van windows.

Reflectix is a poor insulator

The reason Reflectix needs an air gap to function properly is that it works by reflecting infrared photons, which are given off by hot objects. If the Reflectix is touching another object, the heat will be conducted through it, and it will not provide any insulation. In fact, placing Reflectix directly against the metal walls of a camper van can create a microclimate that promotes the growth of mildew and mould and can cause the van to rust faster.

While Reflectix can be effective at keeping heat out in the summer, it is not effective at keeping heat in during the winter. This is because it does not provide any insulation against conduction or convection, the other two ways that heat moves. Conduction occurs when two objects are in contact, and heat moves from the hotter object to the cooler one. Convection occurs when a liquid or gas is not all at the same temperature, causing hot liquid or gas to rise and cold to sink, creating loops of flow that move heat.

There are alternative ways to insulate a camper van that are more effective than Reflectix. One option is to use a spray foam insulation, which can be done professionally or as a DIY project. Another option is to use rigid foam board insulation, which is more expensive than Reflectix but provides better insulation. Other options include wool, fibreglass batting, or cellulose.

In conclusion, Reflectix is a poor insulator for camper vans because it is a radiant barrier that requires an air gap to function properly. When placed directly against the metal walls of a van, it becomes ineffective as an insulator and can even cause damage to the vehicle. There are alternative insulation methods that are more effective and should be considered instead.

Reflectix is a good reflector of radiant heat

Reflectix is often misused by people insulating their camper vans. Many people stick Reflectix directly to the metal walls of their vans, which is ineffective as it turns Reflectix into a conductor rather than a reflector of heat. This is a waste of time and money as it creates a microclimate that promotes the growth of mildew and mould and can cause rusting in the van. To use Reflectix correctly in a van, it is necessary to create an air gap between the Reflectix and the wall. This can be done by using furring strips or leaving the Reflectix exposed.

Overall, Reflectix can be an effective tool for reflecting radiant heat, but it is important to use it correctly by maintaining an air gap between the Reflectix and the surface it is covering. When used correctly, Reflectix can help insulate a camper van by reflecting radiant heat, making the van cooler in the summer and warmer in the winter.

Reflectix is not a good conductor of heat

To use Reflectix effectively, you must create an air gap between the Reflectix and the surface it is covering. This means that if you are using Reflectix to insulate your camper van walls, you should not place it directly against the metal wall. Instead, you should use furring strips or another method to create a small space between the Reflectix and the wall. This air gap is crucial to allowing Reflectix to work as intended. Without it, the Reflectix will become a conductor, and heat energy will pass through it to whatever it is touching.

Another important consideration when using Reflectix is the direction of the heat source. If you are trying to keep your van cool in the summer, you will want to create an air gap between the Reflectix and the exterior of the van, as this will reflect the sun's heat away from the van. In the winter, when you are trying to keep your van warm, you will want the air gap to be between your body and the Reflectix, as this will prevent your body heat from escaping.

Additionally, Reflectix works well as a window covering, as it can help block out sunlight and reflect heat back into the van. However, it is important to note that if you cover the Reflectix with fabric or another material, it will no longer function as a radiant barrier.

In summary, Reflectix can be an effective tool for regulating the temperature in your camper van, but it is important to use it correctly by creating the necessary air gaps and considering the direction of heat flow.
