We installed this garage door in an office building. The goal was to separate the space when needed but allow the light through when closed. They wanted to be able to open the space occasionally. The doors frame is clear anodized aluminum with frosted glass. The manufacture is CHI and it was sold and installed by Aaron Overhead Doors. The garage door is not insulated as the benefits to insulated glass weren’t needed here and the additional cost was too much for the client. We had some obstacles with lighting and ceiling on the other side but managed to double hang the tracks for added strength.
