Tinting polyplastic caravan/coachbuilt windows...

Clankie

I have purchased a new Elddis Majestic 125 motorhome and will take delivery early December. The windows are produced by Polyplastic in Holland and purchased and fitted in the factory in Co Durham.  My present motorhome, a van conversion has darkened windows
but they are glass and they are fitted as standard by Autosleeper in Willersey. We have been delighted with the windows for several reasons. They look very good, they stop the sun damage to fabric, they keep the interior cooler and they assist with privacy.
Is it possible to retro fit a colour tint to polyplastic windows. I have noted many modern caravans with darkened windows. Thoughts please from Club Together.
