Aluminium slats are available in 25mm to 90mm widths and timber in 50mm. There is also a version for audio visual purposes using an interlocking 90mm slat for a higher degree of light exclusion.

Mounted externally, using a reinforced 80mm slat, considerable benefits in solar heat rejection can be achieved. The system is often used on commercial greenhouses to control both light and heat. When used externally, all aluminium components and sections are anodised or powder coated.
