External louvres - shading solution

[actionjackson]

On our renovation project the exposed west elevation will incorporate adjustable external louvres to combat solar gain in an office (above garage), master bedroom and living area - as per this image.

 

It would be great to hear others experiences and what features to consider and how they got on with sourcing and installation.

 

I have started a discussion with Sunshield Unique Louvers- their website is a rich resource and their systems look great but I haven't found any client reviews online. 

 

 

[Andehh]

It's a strong look for sure... Based on zero experience at all, have you looked at external roller blinds, and squaring off the windows at the top?
