In this blog post, we will answer the following question: How do I install Reflectix on my RV windows? We will explain how you can easily install Reflectix step-by-step and discuss its efficiency for RV windows.
How do I install Reflectix on my RV windows?
Putting Reflectix on your RV windows is very easy. Here are all the simple steps you must follow:
- Measure and cut: After measuring all the spaces in your RV, you can cut the pieces of Reflectix you need. The protective plastic comes with a grid that makes it easy to follow the line when cutting and removing the straight pieces without twisting. Also, you don’t need anything other than a utility knife to cut it.
- Peel off the adhesive and stick: But do it carefully. The adhesive is quite strong and sticks just by looking at it. If you put it wrong, it will be difficult to remove it and traces of Reflectix will remain on the surface where it has touched. The good thing is that the Reflectix is flexible and you can bend it to fit it through any gap, no matter how small.
- Smooth: Stretch the Reflectix by hand or use a roller to remove any air bubbles.
- Finish off: Cover beams or areas where you don’t want to waste space with Reflectix tape. It is cut with simple scissors.
If you need more explanation, in the paragraph below we give you a more detailed step-by-step on how to install Reflectix on your RV windows.
How to insulate RV windows using Reflectix
To insulate the windows of the RV, the best we could think of is to use the 20-millimetre Reflectix and place it as an insulator directly on the window. Here’s how you can do it:
Step 1: lay the slats. Place two slats in measures 30 x 20 screwed with some small squares to the sheet. In this way it will help us to later screw the final paneling.
Step 2: Position the Reflectix to insulate the RV windows. We place it directly on the window to achieve that insulation, both from the cold and the heat, and that will also help us to expand the practical interior space.
Step 3: lay plywood for pressure. Once we have faced the Reflectix against the window, we will fasten it with a little duct tape so that it does not fall, to place the 5-millimetre plywood and press, so that it is well attached to the glass.
Now you have your RV windows insulated and you’re ready to go!
How good is Reflectix insulation for RV windows?
When we think of the efficacy of Reflectix insulation for RV windows, the real answer is that it works. Reflectix Insulation comes in 25 ‘x 2’ rolls, shiny, reflective and reflective, in plastic bags. The idea is that this thin material can act as a type of insulation in tight spaces where you can’t put thick fibreglass insulation. There is no metallic content; Everything is plastic.
When shopping for insulation, all those giant balls of fibreglass, stiff foam, and even denim (recycled jeans) can look overwhelming. They are difficult to transport, and if you have a car it is much more difficult. Once you have them at the camper, you need to dress from head to toe to protect yourself from all that itchy fibreglass.
Is there a better way? Does Reflectix offer a reasonable substitute? Not exactly. Reflectix is not a fibreglass alternative. It’s a different type of insulation.
The Reflectix alone does not generate heat or cold. In winter, you will have to have a heat source inside, and once that heat is generated, the Reflectix will prevent it from going out. If you do not have heating, it will help to remove the blinds from windows and skylights during daylight hours, since the sun will enter through there hitting the glass and will heat the room.
In summer, the other way around. If you are not inside the RV, it is advisable to cover windows and skylights with thermal blinds during the hours when the sun hits, to prevent heat from entering and above all, park in the shade. Obvious. To give you an idea, with 2cm Reflectix, in winter you can gain 10º more temperature inside the RV than outside.
Our feelings are very positive. Of course, for it to work, you have to be quite meticulous and insulate well both the floor and the roof, the sides and nerves of the RV. It is also important that, if you do not insulate the cabin, at least put a separating curtain that is insulating since it will prevent the cold and heat from entering.
Also, pay attention to which window and which skylight you put. There is no use insulating everything perfectly if you put a window that does not insulate later. It would be the equivalent of putting aluminum windows in a house, instead of choosing double glazed windows.
Alternative insulators for your RV windows
In the table below we compare four of the most common RV insulators used. We let you decide which one would suit you best.
|Rock wool||It is one of the most widely used insulators, mainly because it is reasonably priced, despite not being the cheapest of the options. They say that it insulates super well, but retains moisture, so you have to use it together with a waterproof element.|
There is rock wool on the market already with an integrated raincoat, which makes your life much easier when it comes to installing it correctly and making sure that water is not going to enter it.
|Expanded polystyrene (EPS) and extruded polystyrene (XPS)||They are rigid plates that also insulate, but since they are not flexible, we cannot recommend them.|
In addition, they occupy a lot more space and are flammable, so … think well.
|Cork||As with the option above, the cork is stiff and in a wavy RV … it doesn’t seem like the best option.|
There are those who use it to insulate the floor because it is hard and they say that it insulates well, but you will also need to put some waterproof element on it, because if it gets wet … you will have gotten it very brown. And the ground, it is easy to get wet.
|Reflectix or Armaflex (cheaper brand, same)||It is the most expensive of all, but with a lot of properties that make it worth the money.|
It is flexible, allowing you to use it on curved surfaces of your RV, such as the wheel arches.It is self-adhesive, which makes it very easy to put on.It is a thermal and acoustic insulator.It is waterproof and prevents condensation (our archenemy that generates oxides on the sheet metal).It is not toxic, so you can handle it with your hands, without gloves, masks, or anything similar.It is self-extinguishing, which means that if the fire reaches it for any reason, it does not spread it.
The bottom line
Insulating your RV windows has multiple advantages. Whether you choose Reflectix or another type of insulation material, the key is to invest in good materials so as to enjoy the benefits of having an insulated RV.
