Unlike a Sunscreen Blind which you can clearly see out of the fabric, the textured nature of the Light Filter softly filters light and gently obscures your view. It is best to order a sample of this fabric if you are considering this option to make sure it is the right fit for your needs.
Combine with a Plain, Thermal or Designer Roller to make this a Double Roller. A Double Bracket requires 90mm frame depth and it drops down 150mm into the window. Best ordered as Inside Fit with the front most facing blind (top blind) Front Rolled. Top Blind is usually the blind that is the most light blocking. Standard roll direction of the lower blind would be Back Roll, unless you need to avoid large handles and then both blinds forward rolling would be the preference. Keep reading for more information.
Standard Roller Blind light gaps apply with Double Rollers
If this applies to you, then it is also considered that Oval Bottom Rails are the most desirable for this set up as the slimmer profile glides nicely over either blind when both in up position front rolled. It is not generally advised that you order Double Rollers for Outside Fit, unless you are ok with large light gaps as front blind with be protruding out into the room 90mm from wall or frame, so would not be ideal for a Bedroom that requires room darkening. If you don't have the frame depth for a Double Bracket an alternative you could consider is one blind Inside Fit (the Light Filter or Sunscreen) and one blind Outside Fit Back Rolled (the Blockout). They would no longer be considered Double Blinds as they are two separate sizes and require separate brackets.
Please note Inside Fit blinds have standard light gaps down the sides and along the top of the window. The size you order for Roller Blinds is the bracket to bracket size, the fabric is 33mm less.
