Holland Blinds or Blockout Rollers these days can be made in a huge range of fabrics. From a more Stiffer Blind Fabric to a Softer Fabric. There is a price difference between these two types of Roller Blinds. Holland Blinds can be made to look traditional or modern. The modern Holland Blind typically has a base rail which also comes in a few profiles. These blinds can fit inside the window frame ( recess - which lets light in above the blind and on the sides - since the cloth is narrower than the blind ) or on the architrave ( face - which has a better light blockout ). Holland Blinds, or Blockout Rollers are used in conjunction with a Screen Roller which are then called DUAL ROLLERS. The Holland creates the Blockout and the Screen Roller the Light Filtering, Daytime Privacy blind.
