Morning All.
I work from home and have a south facing office (upstairs room). I can not change the room, and due to its layout I have to face the window when working.
The sun is driving me nuts - meaning I need to have the curtains closed for most of the day and the light on (how mad is that!

).
Anyone have any suggestions. I could of course go for a blind, but what I am looking for is something which maximizes cutting out the sun but still lets daylight in. Are there coatings out there which might do the trick? Some of you are also bound to work at home so I'm wondering what you do..?
cheers
Mark
