The blind is housed within its own frame. This frame then sits on L shaped angle brackets which are fitted into your roof space to giving an attractive look.
The fitted frame means reduced gaps and therefore improved insulation and light control
Can be motorised so without getting up from your seat, you can filter the daylight, increase your privacy and let daylight in, all at the push of a button. It is available as either mains powered using a standard 3 pin plug socket, or battery operated with optional solar trickle charger, so you do not need to have electrics within your roof space.
