Caravan window protection

Could you not use a heavy material like a dark coloured towelling with some elastic around the edges which would just fit onto the open window?

Or those reflective covers that motorhomers use? They're cheap enough.

There are stickers on my caravan windows warning that if using the blinds you should not fully close them to avoid overheating and damage to the windows.

We have been to Spain/Italy many times and never had a problem, we just leave the windows on 'night vent' and close to blinds about 80%.

It's a pity that the additional track is no longer part of the fitting. Using blinds, however configured can impair the ability to get a cooling breeze into the van. Reflective covers with a bit of bungee shouldn't be beyond most people's skills.

Thank you for the suggestion-I did think about putting a cover on but I think without some form of reflection, the window will just absorb the heat and we won't need any more heat inside the van (40' outside, last year)

I quite agree about the blinds. We always have ventilation in the  van and as in yours, (??Elddis)- the stickers tell you not to close the blinds completely and therefore, we don't. Another thing I noticed, last year, was that the sealing mastic below the window seals started to get very sticky and begin to run a little. My thoughts were to try and find a way to reflect direct sunshine away from the windows, hence my thoughts on using a UV reflective soft fabric.

On our blinds the fly blind bit follows the solid bit. I always leave a couple of cms  of fly blind open at the top. This allows the heat build up to escape, whilst most of the window is covered.

Our blinds are the separate fly screen and heat reflective blind. Although the windows are in the open position, the top of the window is very close to the H.R blind.

Hey HT11 Caravanner …Did you make external window covers after. I’m looking at what the best material to use might be as I know a seamstress who could make them, using elastic to fit inside the window to hold them on when open or closed. I did find a company who mkes them in Europe but they are extremely expensive.
