What a Transom Door Is
A transom door is an entry door with a fixed glass panel above it. That panel is the transom. It sits directly on top of the door frame and does not open. The transom lets daylight into the entry area while the door below handles access. WANJIA Hiseng builds aluminum transom doors as single doors, double doors, and pivot doors. The transom frame uses the same thickened aluminum profiles as the door leaf, so the whole assembly resists impact and corrosion.
On a WANJIA Hiseng transom door, the glass in the transom can be laminated, Low-E, frosted, or mirrored. The door leaf can use the same glass options or a different one. A frosted transom above a clear glass door gives privacy without blocking light, for example. The aluminum frame is finished with fluorocarbon coating, wood-grain transfer, anodizing, or powder coating. These finishes hold up in wet and coastal conditions because aluminum does not rust.
How a Transom Door Is Built
WANJIA Hiseng makes the transom as a separate fixed frame that attaches to the top of the door frame. Same thermal break design as the door frame, with a non-metal barrier between the inside and outside aluminum faces. That barrier slows heat transfer through the metal. The transom glass is sealed into the frame with multiple sealing strips. Those same strips run around the door leaf to block drafts and water.
The door below the transom can be a single door, a double door, or a pivot door. A double door with a transom gives a wide opening and a tall glass area above it. A pivot door with a transom works well on modern homes because the door swings on a pivot hinge instead of side hinges. WANJIA Hiseng also builds combination units where sidelights flank the door and a transom runs across the top. That creates a full glass surround around the entry.
Transom Doors Over Double Doors
Transoms sit over double doors all the time. Two leaves meet at the center. One leaf may be active, the other fixed. Or both open. WANJIA Hiseng makes aluminum double doors with a multi-point lock on the active leaf. The fixed leaf locks to the frame with flush bolts. When a transom goes above a double door, its frame spans the full width of both leaves. The glass is one continuous panel, or it is split into sections to match the door below.
Builders pick double doors with transoms when they need a wide clear opening. The transom adds height without making the leaves taller. That keeps hardware at a comfortable height. The glass above brings in more light. WANJIA Hiseng offers double doors in several configurations. Equal leaves, unequal leaves. The transom can be sized to match the total opening width.
Which Way Does It Swing?
Order a transom door and you have to tell us the swing. Stand outside and pull the door toward you. Hinges on the left, it is left handed. Hinges on the right, right handed. The transom itself does not swing. The door below does, and that changes where hardware gets drilled. WANJIA Hiseng asks for swing on every order, so the lock body goes on the correct side.
Double doors are more specific. The swing tells us which leaf is active, the one that carries the handle and lock. The other leaf stays shut most of the time. The transom above does not care. The frames do, so we machine the transom frame and door frame together. That keeps screw holes and seal channels lined up, whichever way the door swings.
Double Door Types That Take Transoms
WANJIA Hiseng builds casement double doors with leaves that swing on side hinges and meet at a center astragal carrying weatherstripping. A transom above adds a fixed glass panel matching the door width. That is the most common setup we sell. It is simple and it works.
Pivot double doors use a pivot hinge set near the top and bottom of the frame. The pivot carries the weight differently, so these doors can be wider than casement doors. Wide openings, commercial entries, modern homes. A transom above pivot doors works well because the frame is already built for the load.
And we also build full-open double doors where both leaves fold or slide out of the way. Put a transom above one of those and you get a continuous glass band up top while the doors move below. The glass area stays clean, no visual break between transom and door when closed.
Glass and Hardware for Transom Doors
The transom glass is fixed, so it needs no hardware. The door below needs a lock, handle, and hinges. WANJIA Hiseng fits Kinlong hardware as standard. Hoppe, Cmech, VBH, and G-U are available as options. The lock can be a multi-point type that throws bolts into the frame at several points. For smart entry, the factory can fit a fingerprint lock, password lock, card access, or remote unlock. The smart lock can tie into a home automation system through an app.
The transom glass can be laminated for impact resistance. Low-E glass cuts solar heat gain. Frosted glass gives privacy. Mirrored glass reflects heat and light. WANJIA Hiseng can also put grilles inside the transom glass to match the door below. The grilles are aluminum bars sealed between the glass panes. They do not need cleaning and they do not rattle.

Start on the double doors page for standard configurations. The pivot doors page shows a transom on a pivot hinge. Need the factory behind it? See the manufacturer page. Every transom door uses thickened aluminum profiles, thermal break frames, and multiple sealing strips. Weather and daily use, it holds up.
FAQ
What is a transom door?
An entry door with a fixed glass panel above it. That panel is the transom. It sits on top of the door frame and does not open. WANJIA Hiseng builds these as single, double, or pivot doors. The transom frame uses the same thickened aluminum profiles and thermal break design as the door frame. Glass can be laminated, Low-E, frosted, or mirrored.
Can a transom door be a double door?
Yes. WANJIA Hiseng builds double doors with transoms. The transom spans the full width of both leaves. Leaves can be equal or unequal. One leaf can be active and the other fixed. The transom adds height and light without making the door leaves taller. So the factory machines the transom frame and door frame together. That way they align perfectly.
What is the difference between a left handed and right handed door?
A left handed door has hinges on the left when you stand outside and pull the door toward you. A right handed door has hinges on the right. The transom is fixed and does not swing, so it works with either swing. WANJIA Hiseng asks for the swing direction on every order, then drills the hardware holes and installs the lock body on the correct side.
