These frames will be included in the fabrication of the hangar door. After hangar door installation, a window contractor will be responsible for the installation of the window, trim sealant.

The choice of window design and specification will be limited only by depth and width of the door leaf. A conversation with a hangar door manufacturer at the very beginning will help determine these parameters.

A translucent wall panel needs to be braced horizontally and vertically by the hangar door so early integration is advisable. . After the hangar door is installed, a sheeting contractor can apply any additional bracing and fasten the translucent panels to the hangar door frames.

In some cases there will be obstructed views behind the glass or translucent panels because of the x-bracing or structural steel which the hangar door leaf needs to maintain structure and prevent sagging. These are reasons to talk to a hangar door manufacturer during the initial design phase to find out if this will be apparent on yours.
