To the Window to the Wall… an inspiring look at Steel Windows

Steel windows have the structural integrity to allow for a full wall of mostly glass. When designed properly, the effect can feel as though you have more than doubled you living space.

What are the benefits of steel frame windows?

  • Due to the material’s strength, steel windows have very slender sightlines. A minimal amount of framing material is needed for structural integrity, offering clean and clear views.
  • Steel frame windows span architectural styles, working well in both traditional and modern houses.
  • All corners and joints of steel windows are welded, galvanized, and powder coated, forming an unbroken surface around the frame.
  • Extremely durable, steel frames are resistant to decay, weather, and fire. They are galvanized (coated with a layer of zinc at very high temperatures) to prevent corrosion.
  • Unlike wood, steel window frames do not contract and expand in response to weather conditions.
  • Require minimal upkeep compared with wood windows and doors.


The framing around industrial style steel doors can be pencil thin (unlike wood, which requires a large beam to support a door).

Are steel frame windows energy efficient?

Bottom line is that metal is a poor insulator, and the thin steel and single sheet steel factory windows of the past did little to keep out the cold. The good news is that 21st century technology has caught up, and you can get the same historic looks with better materials and thermal efficiency.  detail

Steel windows are available with insulated glazing panels; two or more pieces of glass are spaced apart and sealed, leaving an insulating air space. Another new technology called thermal breaks (whereby a material is placed between the inside and outside window frames to prevent thermal energy loss), common in aluminum windows, is available in steel windows. Steel fabricators will point out that steel itself has good insulating properties as compared to aluminum and thermal breaks may not be necessary. In fact, there are steel frame windows that meet LEED standards. Refer to fabricators’ websites for details.

Another consideration is that many fabricators roll their steel windows from 100 percent recycled steel. And, the new product can also be recycled at the end of its long life.

Like any window, the glass in steel framed windows can be UV-coated to protect indoor furnishings and art from sun exposure.

Are there different styles of steel windows?

Steel windows are available in a range of looks from factory-style with a floor to ceiling collection of panes, to Frank Lloyd Wright-inspired style (his Falling Water House famously used steel windows), to a modern minimalist look with large panes of glass supported by pencil-thin sleek steel frames.


Steel windows are available in a multitude of operable variations including: casement, in-swing, out-swing, awning, horizontal pivoting, vertical pivoting, folding, and hopper.

Steel Windows and Doors Hess Hoen Architects, Gardenista

Steel doors are not commonly offered as sliders (Euroline does offer sliding pocket steel doors). Those seeking a full open outdoor wall experience, as in this project by Sydney-basedHess Hoen Architects, often go with folding steel doors.

How much do steel frame windows cost?

Steel frame windows are expensive. Like many aspects of a home remodeling, steel window pricing is very site specific. Is it a single window replacement? A full remodel? Custom or standard sizing? The best way to estimate cost is to get a quote from your contractor or window supplier. In general, expect prices to be at least double that of wood, more than aluminum, but less than bronze. Remember to balance the cost with the longevity (imagine replacing a full wall of 15-year-old weather-worn wood windows) and other attributes.

Where can I buy steel factory-style windows?

Beware of cheap imitators. Suppliers of fabricated windows and doors that come highly recommended by several architects and builders include:

  • Crittall. This venerable company founded in 1889 in the UK has provided windows and doors to Yale University, Walter Gropius, and the New York Botanical Gardens.
  • Dynamic Architectural Windows and Doors.
  • Hope’s. Located in Jamestown, NY, Hope’s makes top-of-the-line steel and bronze windows and doors.
  • Bliss Nor-Am. This Rochester, NY/Canada-based company makes high-quality, beautifully detailed powder-coated metal doors and windows.

Can I use reclaimed steel factory windows?

Yes! Reclaimed steel factory windows can be found at architectural and design salvage yards. Keep in mind that the price of fabulous vintage looks may include needed repairs and re-coating.

Reclaimed steel factory windows found architectural supply yards, such as Heritage Salvage cannot, obviously, be customized to your setting; rather, your setting may need to be customized to fit them.

Steel Frame Windows Recap


  • Strong
  • Slim sightlines
  • Work with a range of architectural styles
  • Durable and long lasting
  • Low maintenance


  • Expensive
  • Heavy
  • Not the best choice in climates near salt water. More protection and proper finishing is required to prevent airborne salt corrosion
