A transom — the glazed panel above a door — adds daylight and height to an entrance. In commercial and hospitality projects, transoms are specified as matched door and transom assemblies. Here is what to consider when specifying them.
Fixed vs Operable Transoms
Fixed transoms are the most common and simplest to build. Operable transoms open for ventilation, and are common in older-style commercial buildings. Confirm which type the architect has drawn.
Materials and Glazing
Wood and aluminum-wood transoms match timber doors; aluminum transoms suit glazed commercial entrances. Use tempered or laminated glass and check the local glazing code for safety requirements.
Matched Assembly
Ordering the door and transom from one factory ensures the frame, sightlines and finish match. Jusen manufactures the door, transom and side panels as one assembly.
