Does anyone know of a Company that specialises in Screening for windows and/or doors. I have a large glass door, that one of my 'elderly' dogs (and a cat too) like to sit in this small room. However, it can become very warm in the Summer, but they refuse to move! I do put a fan in the room when they are about, but I would like to see if there is something that I could put on the OUTSIDE of the glass, that would reflect the sunlight back out, and also shade the room.

Anyone know of anywhere please? (or ideas) THANK YOU

you can buy rolls of it from car accesorie shops, it peels off a backing and you smooth it on, -bit like wallpapering, i did the rear windows in one of my cars with it, really kept the heat out
