Hi
Has anyone tried painting a caravan pop up roof with reflective paint?
I see that my portable 9000 BTU Aircon struggles when the van is not under some sort of shelter, and I am thinking of making the fiberglass roof more reflective

Rather buy a reflective sheet, that will cover your van and tents.

Good idea! There is a special white paint that they claim makes houses with corrugated roofs a lot cooler. Should work on caravans as well.
Koop n reflective sheet. jy gaan net jou karavaan dak beskadig. Die verf is maklik. Om die fout indien so, reg te stel is n ander storie.
I think the effect will be minimal, if at all, but if you do try it, please update us. Someone has to take the lead.
Ek het al paar keer by Dolphin gesien n ou met n Penta wat n silwer seil het wat spsifiek gemaak is vir sy opwipdak. Hy het rekke in.....dit werk presies soos n paslaken vir n bed
Onthou. Veselglas gee n olie laag af en as dit nie reg behandel word en die regte onderlaag en verf gebruik word gaan dit af dop.
Die Dak word ook baie bloot gestel aan hoee graad hitte, dus moet die verf dit ook Kan akomodeer. Sover my kennis strek is daar nie wye keuses op silwer en seker maak jy kry proffesionele leiding met prep, verf en aanwending
Someone on the 4x4 website recommended the silver sided cover over the top, but also mentioned you need an air gap under the cover for maximum effect.
the fiberglass roof is already colored white, so I am going to investigate whether it can be painted with something like Aluminium paint
Maybe there is some useful info.....

Hendrick. Dit klink baie goed.
Info wat ek beslis sal onthou. Het jy enige idee hoe die finale afwerking van die verf lyk ?

Ek lees dit het 'n "low sheen" afwerking. Gaan die winter 5l koop en my stoepie se dak verf.
In verskillende kleure te koop.

Maak maar netseker of jy nie eers n galvanized primer moet opsit nie
Dankie vir die raad.

I have thought about it myself. Then i did a bit of investigating and found that the reflective sheet I have becomes rather hot in the sun. That heat should somehow transfer to the inside of the caravan. This let me to believe that any sheet cover placed over you caravan and tent would give the cool effect but that's something I will test in my own time.
So the coolness of the sheet for the tent and caravan in my mind lies in the fact that the silver sheet is not actually part of the tent and caravan roof itself and the heat of the silver sheet however lower than that of any other sail/canvas is not all transferred to the caravan or tent.
By painting the roof with the silver reflective paint or that mentioned by Hendrick should reduce the heat inside the van but I doubt that it would have the same effect as a silver sheet.
It is some thing that needs to be tested.
There is however a member on the forum that painted the roof of his Camper with such silver paint. Froggy if I remember correctly. Maybe some one can get him to give us detail feedback on some firsthand experience.
I think it is a good idea. But, it is something I will first test before I do it. Paint some normal white paint and the reflective paint on small pieces of metal sheet and put it in the sun. leave a small gap under each sheet and then measure the temperature below each sheet. If the difference in temperature is what you consider being forth it then consider it. You will probably find that a clean and shiny roof will also provide you the same result as the reflective paint. Therefore, maybe a good idea to clean and polish the roof.
I know the reflective sheet will still work the best, When all the trees and shade is taken in a camp when I arrive, I use it and it works very well. I was told that the reflective sheet reduces the temperature by 40% on top of the roof which then make a nice difference under the roof. You can actually feel it when touching the canvas before and after putting the reflective sheet over.

above talks about reflective paint on building roofs.
speccoats.co.za advertises a high reflective white paint. Appears that white is actually better than silver due to higher emmisivity of the heat even though less reflective

Great idea Piet is suggesting. Keep in mind that its actually the temperature on the bottom of the plates you are interested in as the roof is represented by the plates.
The plates will get hot in the sun and so will the roof. That heat will transfer into the caravan. How much heat we must find out. At least it would be less than with a normal roof.
Thus with a reflective cover over the roof the roof is in the shade of that cover so the roof itself does not become hot.
So I think the big issue is what is the temperature difference between a roof painted with the special paint and a roof that is totally in the shade under a cover.
My money is on the roof under a cover that provide shade for the roof.

Sal dit ook aanbeveel, ek het vir jou een wat goed kan verf hy verf tans my huis.

Bietjie ver van jou af. Drie vrae oor die Cooltech verf Jin.
Sink dak of teel dak?
Hoeveel vk meter per 5 liter.
Het jy eers primer op geverf soos Geert aanbeveel?

Tans is ek besig met teeldak.
Die afdakke is sink en klaar geverf, eers gewas on die vet en olies after kry en toe primer en dan verf.

Dankie. Sal so maak.
Would there be any value in parking two cars out in the sun side by side, one Silver and one White. Close all windows and leave for an hour or so with temp gauges in each car.
After an hour check both temp gauges for comparison. If one does this with for example a Red and a White car there is an enormous difference.
I am of opinion that the true value of the difference in temperature under a silver sheet and that of a caravan and tent without such a silver sheet lies in die shade that it provides an not so much in the fact that the sheet is silver reflecting the sunlight.
Surely there will be a difference in the underside touch temperature between a normal canvas sheet and that of a silver sheet. The effect of the shade that it provides on the tent and caravan below is basically the same.
Something that's to be tested.
Ek sal baie graag eerder 'n seil dieselfde kleur en tekstuur as my karavaan tent dak bo oor wil span vir die koel effek as wat ek daai onooglike blink seil gebruik.

Ek dink as jy n spasie los tussen jou seil en dak gaan enige seil n verskil maak. Dieselfde beginsels as tenthuise wat mens in oorde kry doos Devoetpadskloof en KNP.
.....maar dis heelwat werk om so op te slaan

In die grens oorlog jare het van die tente 'n dubbel tent dak gehad met 'n spasie van ongeveer 30cm tussen die twee dakke. Dit het 'n tamaai verskil gemaak in die leefbare temperatuur in daai tente.
Ek is gemaklik met die gebruik van die silver seil tans. Ek gaan net 'n plan maak om die silver seil te vervang met ander materiaal wat basies lyk soos my tent se dak.
Dalk van die Rekbare tente materiaal wat deur maatskappye soos Redbull gebruik word. Daai wat sulke punte staan.
Dit is baie ligter, maklik om op tevou. Weet net nie hoe lank daai materiaal sal hou nie. My silver seil is na 9 jaar basies op sy einde.
