A curtain wall is a glass exterior wall hung on the outside of a building's frame, usually running past the floor lines across several stories. Aluminum storefront framing sits inside a single opening, most often at street level, held between the floor and ceiling of one story. Liberty Door Supply handles both for commercial buildings in New York City, and the quickest way to tell them apart is where the glass stops.

How can you tell a curtain wall from storefront framing?

Start with the floor lines. On a curtain wall, the glass and its aluminum framing run across the face of the building and pass in front of each floor edge. From the street you can often spot horizontal bands at every floor where the glass turns opaque. Those bands are called spandrels, and they hide the floor slab and the ceiling space behind the wall.

Storefront framing sits inside an opening instead, usually at street level. The top of the storefront meets a ceiling, a beam, or the floor above, and masonry or columns frame the sides. If the glass stops at the edge of the opening rather than continuing up the building, you are probably looking at storefront.

The two systems also do different jobs. A curtain wall is the exterior wall for the floors it wraps. That makes it part of the building envelope, the outer layer that separates inside from outside. Storefront fills one opening and often holds the entrance.

What the facade service includes at Liberty Door Supply

Liberty Door Supply's curtain wall and glass facade service deals with the glass exterior as part of the building envelope. On a new building, that means a framed glass wall on an elevation, which is one face of the building. On an existing commercial building, it means facade glazing that is being replaced or updated.

A facade project often runs into neighboring work. Where the facade meets the sidewalk, aluminum storefront framing may take over. Entrances set into that framing belong to storefront glass and aluminum doors. A cracked or broken pane in an existing facade starts as a glass repair and emergency board-up request.

Projects that usually point to a facade scope

A new commercial building or addition with glass across more than one floor is the clearest case. If the drawings show the exterior wall as glass running past the floor lines, the request belongs with curtain wall and glass facades.

An existing building getting a new face is the second. Replacing aged facade glass, or reworking an elevation that is already glazed, stays in the facade category when the glass spans floors.

General contractors carrying a glass exterior package inside a larger renovation fit here too. Separating that package from storefront and interior glass early makes the scope easier to discuss.

Facade glazing, storefront framing, or glass repair?

Each of these services answers a different problem. Match yours to the closest line.

  • Curtain wall and glass facades: the glass exterior wall itself, usually spanning floors and passing in front of the floor edges, on new or existing commercial buildings.
  • Aluminum storefront framing: glass framed into an opening at street level, held within one story, often around the entrance.
  • Storefront glass and aluminum doors: the doors set into that ground-floor framing, when the question is the entrance rather than the wall.
  • Glass repair and emergency board-up: a broken or damaged pane that needs securing or replacing while the rest of the system stays as it is.

If your project touches more than one line, say so up front. A facade replacement that also changes the ground-floor entrance can be described in a single call, as long as each part is named.

What to gather before you ask for a scope

None of this needs to be technical. A few plain details make the first conversation useful:

  • The building address and borough
  • Which elevations are involved, such as the street front, a side wall, or the rear
  • Whether the work is new glass or replacement of an existing system
  • Existing drawings or photos of the facade, if you have them
  • The person coordinating the project on your side

With those details in hand, call Liberty Door Supply at (347) 928-7349 to talk through whether your project is a facade scope, a storefront scope, or both. Regular hours are Monday through Friday, 7 AM to 6 PM.

Frequently asked questions

Can one project involve both a curtain wall and storefront framing?

Yes. Many commercial buildings have a curtain wall on the upper floors and aluminum storefront framing at street level, and Liberty Door Supply offers both as separate services. When a project includes both, point out where the two systems meet so the line between the facade scope and the storefront scope is clear from the first call.

Which boroughs does Liberty Door Supply work in for facade projects?

Liberty Door Supply takes on curtain wall and glass facade work in New York City, across Manhattan, Brooklyn, Queens, the Bronx, and Staten Island. Mention the building's address and borough when you first get in touch so the conversation starts with the right location.

Who should be on the first facade scoping conversation?

The first facade scoping conversation goes best with the person who coordinates the project, such as the owner, property manager, general contractor, or facility lead. If someone else holds the drawings or photos of the facade, having that person available lets questions about the existing glass get answered on the same call.

What if a glass facade panel is broken and the building needs securing now?

A broken facade panel that leaves the building open is a glass repair and emergency board-up request rather than a facade scope. Liberty Door Supply offers emergency board-up 24/7. Replacing the panel afterward falls under glass repair, or under the curtain wall and glass facade service if the whole exterior is due for broader work.
