Timber look aluminium panels
Aluminium powder coated slat sizes are available in 38mm, 65mm and 90mm wide. 
The spacings between the slats need to be as per your council regulations but they are usually around half the width of the slat.
(so a slat size of 65mm it needs to have a spacing of around 32mm)
Council regulations change between areas and are also dependant on factors.

Timber-look Red Cedar is also available.
