Adding a roller blind to increase bedroom blackout

Posted by on Aug 21, 2012 in Roller Blinds, Roman Blinds | No Comments

Roman blinds are a wonderfully versatile product with huge benefits – aesthetic and practical. However we always advise our customers that when located outside the window recess/reveal, they should not be your first choice if you’re looking for complete bedroom blackout.

This is because roman blinds hang proud of the wall when lowered, enabling light to spill into the room around the sides.  The effect is further exaggerated when a chain driven mechanism is required (typically for large blinds), as the mechanism tends to be deeper than the traditional wooden battens that work with ropes and cleats.

Where you have a roman blind sitting on the outside of a sash window architrave, there is very little space behind the blind to house any additional blackout options

So when one of our existing customers came back to us to discuss how she could increase the blackout in her child’s bedroom – for a blind ordered a couple of years previously, we were keen to find a solution that worked with the existing blind.

The problem was that the window reveal was taken up with the sash window frame, leaving very little room to house any form of blind behind the existing roman blind.

A section of the sash window (staff) bead is carefully removed to accommodate the roller blind bracket. The roller blind is made to the maximum width to maximise blackout potential, and the fabric is reverse rolled to enable the fabric to clear the staff bead.

The solution: with careful planning we calculated that we could fit a spring loaded roller blind inside the sash window frame itself. It was important for the roller blind to be spring loaded, as a chain would not be operable in this tight space and would also diminish valuable fabric width.

We carefully removed a section of staff bead at each side of the sash window frame, to accommodate the roller blind brackets. We specified the roller blind to be reverse rolled (ie the fabric rolls over the front of the mechanism rather than down the back, which enables the fabric to clear the staff bead).

Although the overall fabric width of the roller blind was only just wider than the sash window itself, the overall effect was to substantially reduce the light coming into the room, which, when combined with the roman blind achieved the blackout effect our client was looking for.
