View the two expansion plans
| Location | Announced investment | Space and purpose | Announcement and timing |
|---|---|---|---|
| Huntsville, Alabama | $70 million | 112,000-square-foot support facility; frees existing manufacturing space for aircraft windows | October 7, 2026; no completion date stated |
| Shelby, North Carolina | $380 million | 198,000-square-foot new coatings and sealants plant | May 8, 2025; originally expected first half 2027 |
Equal-size boxes describe one project each; their areas do not represent investment amounts. Project scopes differ. Neither announcement establishes completed capacity or a return on investment.
PPG's aerospace growth reaches beyond the paint on an aircraft. The company also makes cockpit and passenger windows, and is spending $70 million to expand the Alabama site that produces them. [2]
Its October 27 results give that expansion a timely backdrop: aerospace organic sales again grew by a double-digit percentage, with orders waiting to be filled near $300 million. Organic growth excludes currency movements and acquisitions, but includes price changes. [1]
Moving the support work makes room for windows
The Huntsville expansion, announced October 7, has a practical design. PPG will lease and fit out a new 112,000-square-foot building for production support. Moving those functions creates more manufacturing space at its existing window facility. [2]
PPG calls these products aerospace transparencies: the windows through which pilots and passengers see. Its customers span commercial, military and general aviation. That gives the operation more than one type of aircraft demand to serve. [2]
“Demand for aerospace transparencies continues to grow across commercial, military and general aviation markets”
Francois Buehlmann, PPG general manager, global transparencies, Aerospace - October 7, 2026 [2]
The announcement describes a series of multi-year projects, without a completion date. More floor space creates an opportunity to produce more; it does not establish how many extra windows PPG has already delivered. [2]
Aircraft makers buy materials as well as components
Windows are one part of a broader product offering. At a June investor event, PPG highlighted seal caps and 3D-printed sealants alongside its coatings. The company says these technologies can help aircraft manufacturers work more efficiently and reduce waste. [4]
That makes the commercial pitch about how aircraft are built as well as what covers their surfaces. A supplier that helps customers apply materials more effectively has another way to compete besides selling a can of paint. Those efficiency benefits are PPG's claims, with no product-by-product sales figures in the event recap. [4]
The market connection For PPG shareholders (NYSE: PPG), aircraft demand can reach the business through windows, coatings and sealants. New capacity earns its keep when those products reach paying customers. [1]
A second factory has a different job
PPG's larger project is a planned $380 million coatings and sealants plant in Shelby, North Carolina. Its May 2025 announcement described a 198,000-square-foot facility producing the full aerospace range, with manufacturing and warehousing together. [3]
The original timetable called for completion in the first half of 2027. PPG said the added capacity and nearby transport links would help customer service. That remains an expected benefit of a planned facility; the announcement is not evidence that it is already operating. [3]
Demand has persisted rather than suddenly appeared: the July results also put aerospace orders near $300 million. [5] Elsewhere, PPG's latest report shows input-cost inflation squeezing Industrial Coatings profit, so aviation strength does not describe every business. [1]
The opportunity is tangible: more places to make aircraft windows and materials. The remaining work is tangible too: finish the projects, equip the space and turn waiting orders into deliveries.
