BLACKOUT BLINDS Traditional Blackout Roller Blinds will have light bleed down each side due to the gap between the fabric and the bracket Silent Gliss & SHY have an excellent system to combat this. On this project we have used the Silent Gliss 4770 Electric Dim Out Blind Systems With a 90mm Headbox and Side Channels, this system provides a cassette around the roller blind to provide maximum blackout. A zip in the channels holds the fabric securely in place when the window is open The brush on the bottom bar enabled the limits to be set as tight to the cill as possible although a bottom channel is available if the cill is unlevel and will cause light bleed #blackoutblinds #dimoutblinds #specialistblinds (at London, United Kingdom) https://www.instagram.com/p/CZr-jFOIDOO/?utm_medium=tumblr
