Glass material headaches

[dbaldzhiev]

I would appreciate if anyone can help me with a simple vray glass material.

 

I'm doing an interior scene, lighting it with a HDRI image, I have a glass surface with glass supporting elements basically looking like that http://img.archiexpo.com/images_ae/photo-g/curtain-walls-aluminum-glass-58173-1905769.jpg. This is my main source of interior light. I got the light to come inside but the glass material looks extremely weird. I'm posting my settings and a region render. The problem is that the material reflects completely the inside space.
