At work we’re currently in the process of building a large addition for a private school. The principal of the school asked us if there were any door options that would allow for privacy in the classrooms in an emergency situation where the school might be in a “lock-down” mode. I mentioned that we’ve successfully used exterior doors with built in blinds which might make a great option.
In the photos you can see a Therma-Tru fiberglass exterior door with built in blinds. This door has been installed as an entry door to a classroom inside the building. It may seem a bit strange to install an exterior door in an interior application but there are some benefits by doing this.
If you’re going to order an exterior door with built in blinds for an interior application you need to be aware of some key issues.
Most manufactures are now offering doors with built in blinds. When inquiring about them you’ll most likely be looking at their French Door collections. These doors also work great for offices and conference rooms.

You did not mention two important considerations that are required by many codes- fire rating for the door and width. Especially in schools and hospitals there are codes requiring a certain width (for access and egress) and fire rating (how long a door can "hold back" a fire). For rennovations, an older door may require enlarging the frame to meet new codes.
One other concern is the amount and type of volatile chemicals used on exterior doors - does anyone know if this could be problem using them in interior spaces?
El - You bring up important design considerations. For the application mentioned above the doors are being used through walls that have no specific fire rating assembly. These would not meet a fire rating if the wall was a rated assembly. The door make up really isn't a problem unless it had a high fire spread rating which they do not.
How easy are the blinds to repair on these? Would love to put some in at my place but worried about damage, would i have to replace to whole door?

Emma - If they get damaged the glass unit that contains them must be replaced not the whole door. I can tell you that I've never had trouble with the ones we've used from Therma-Tru and Jeld-Wen.
Todd,
Do we have a standard thickness of exterior and interior door in States?

Jin - Most standard doors are 1-3/4" thick.
Are 96in x 96in sliding doors w/ built in blinds available?
