I adore these doors.  They're special, like window-doors.  They're very modern looking.
I didn't want a solid door because I wanted more light.  Yet these doors help with noise, temperature, security--everything a door does.  I've been surprised at how much they help with noise. 

Post note:  The door fell apart.  I contacted customer service, but they never got back to me.  No one slammed the door, it just leaned off its hinges and pieces of wood fell to the ground.  My carpenter is going to put long screws into them to make them work.  Wayfair didn't meet my expectations.
