External Silver Screens causing water leak

When we had a coach built Autocruise we had slight water ingress on the nearside door when it rained and the silver screen was fitted it was cured when the nearside door was "adjusted?" to make a tighter seal

It doesn't take much to alter a seal so all things are possible if something is introduced to the system, it doesn't have to be a large volume either.

Hope all this has helped the op.

At least you could identify the cause, Steve. There has to be a reason such as your 'crinkle' or JV's misaligned door.

Thanks so much for all your replies and thoughts - just to answer a few questions:

The motorhome is a 2019 Knaus (Fiat Ducato) with the thicker Remis cab blinds.

We've had very heavy rain in Sussex this weekend - it's definitely not condensation, and the leak happens on both sides, but only when the Screens are fitted. 

They are genuine Silver Screens (for the appropriate blinds) and the company has been great, offering advice and even a full refund - but we really want to make them work!!

Our dealership did a water test (without Screens), basically blasting a hosepipe at each window for a few minutes, and there wasn't a problem. Annoyingly, they wouldn't do one with Screens - which would have proved the point!

Thanks again for your replies - it's much appreciated (as the Sussex rain begins again on a naked windscreen).

I think the clue is your reference to the 'thicker' Remis blinds...I can't specifically give any advice as we don't use external blinds (and we have an A Class van) but if the thicker blinds are putting the screen under more tension, the tops of the doors may be being pulled away from the 'fully closed' position.

if the doors are fine without the blinds, it must be how the blinds are working..

Other than that I can't think how the doors are being affected.
