Risskov, Denmark - pretty cool place, seems to be very involved in music and software. Anyway, I was surfing the web to find out what the weather was, because I suggest that you let the sun have a go at it. I've had problems in the past with material that after a few hours in the sun you would have never know problems like wrinkles existed. Of course I live in Austin, Texas where things melt.
If you can tension the screen on a frame and place it in direct sunlight next to a window or on a patio, you might be surprised.
Hope this helps.
