We have a birdcage with a west exposure so we get the afternoon sun and we still use it a lot year round but it does get warm in the summer months. I really don't think the difference in mesh for the roof will affect the temperature in the birdcage but the heavier mesh will cut the exposure to the sun a bit more on your skin. If you have a pool or are a sun worshiper, I would go with the lighter mesh. If you like to lay out but still have relative shielding from the suns rays, the go with the heavier cloth. Ask T&D what they suggest.
