I am going to do a bath remodel and remove some glass blocks in my bathroom and replace them with a window
I am in seattle area.
rest of the windows are white vinyl, no idea of the brand. I want to keep a similiar look from the outside.
Most important is that it is energy efficient
Probably double casement 4 x 4

My contractor wants me to buy the window and he will install it.

Looking for advice on where to buy, and what to get.

Hoping to keep cost under $500
