Select "external louvre / vertical blind" for devices that pull down or across to completely cover the window. This includes motorised blinds, fixed blades or sliding screens with fixed or adjustable blades.

Select fixed or adjustable louvres or blinds depending on whether the louvre or blind can be retracted to permit winter sun.

Note: Devices that do not completely cover the window cannot be nominated using DIY.
