What does Standard or Reverse Roll mean?
Roller blinds can be installed in two ways, with the fabric rolling (unravelling) closer to the glass or with the fabric rolling away from the glass.
The "Standard Roll" option means the fabric will roll from the back of the tube, closer to the glass. This brings benefits such as better thermal retention and light reflection (particularly useful for blackout fabrics!).
The "Reverse Roll" option does just the opposite, meaning the fabric will roll from the front of the tube, away from the glass. This is beneficial if there are window handles to clear, and usually a preferred option for creating the seamless look as you do not see the roll, as it is concealed by the fabric rolling from the front of the tube.
