25mm aluminium Venetians, so called ‘Slimline Venetians’ are a standby for wet areas because they are very practical in that they allow privacy control and air flow, and also because they are very inexpensive; probably the next least expensive window treatment after basic fabric roller blinds and vertical blinds.
Surprisingly the 50mm aluminium venetian of '50s and '60s popularity is still available in today’s fashion colours. This is the same size blade as the timber look PVC venetian which has taken its place. The thinness of the metal blades in the open position provides an attactive clean view compared with the more bulky PVC version. Worth reconsidering.
