Hello everyone! Well my problem is quite simple – I decided to turn my bedroom into a theatre/gaming room, using a projector I have but it seems that I’m having trouble with the quality of the image because of the sun streaming inside. So now I have two options: to permanently graze the windows or cover them in a type of blinds named blackout. It seems these ones completely block the sunlight from entering the room. I found some black ones in roller style here Roller Blinds, Made to Measure Blinds, Online Roller Blinds UK that I like but want to know whether do they work or not. I’m not found about glazing the windows, a person needs light too. Any advice would be appreciated.
