Dim Out Blind - Roller Blind

Dim out blinds are an option for Audio Visual rooms and school laboratories where darkening for slide shows is adequate. In bedrooms, especially children’s rooms where evening summer sun will prevent sleep and an early dawn will be less than welcome, they can be more practical than curtaining.

The fabric is 100% blackout PVC coated fibreglass that is flame-retardant. It is fitted to an Easi roll or Automatic Spring roller. For large blinds gear operation with a cranked rod or motorised blinds are available. Any colour as long as it is black? No we have a wide colour range of plains and patterns

Ideally it is fitted outside of the window reveal so that the cloth is at least 75mm wider than the opening at the sides and top. The wall then blocks direct light from round the sides of the blind.

If fitted in reveal, unless there is a deep window frame, direct light will be seen at the edges as, depending on the blind size, the cloth will be at least 20mm narrower than the opening size.

A lining at the top and sides can be used to reduce this light. Hallmark side masking is from 75 x 25mm aluminium angle or 70 x 20mm timber with a 30 x 30 mm fixing fillet. A fabric pelmet or a Cassette roller blind box are alternative options for the top. 

If linings are formed during the building works they must have smooth edges where the cloth might touch them.

An effect of dim out is that because the cloth is 100% blackout when the blind is pulled down as your eyes adjust to a lower light level the light around the edges will become more exaggerated. If a better light seal is needed a VS650 dark blind should be considered.

Easi-roll blinds are only supplied with chain child safety devices
