I already have radiant floor heating installed. I have been searching around and thinking more about the doors. I am either going to go with a jamb tilt door, or my original idea of swing out doors. The tallest opening would be 9'1/2" tall X 10' wide. I like the idea of the jamb tilt, but having a hard time even finding them on the internet. Seems like Australia likes them! Roll up doors would require me to leave room inside for the door and hangers, plus I had lights planned for that area.
