Corning and All Weather Group have partnered to bring Enlighten™ Glass to the Canadian market in new quadruple‑pane window units. The collaboration will enable the production of ultra‑thin, high‑strength glass that supports larger, higher‑performing window configurations while reducing weight.

Corning’s building‑materials segment grew 8% year‑over‑year in 2024, generating $1.2 billion in revenue and accounting for 30% of the company’s total sales. The segment’s operating margin was 18% in 2024.

Corning’s chief financial officer said the partnership would accelerate the adoption of high‑performance windows in Canada and support the company’s “More Corning” strategy of integrating advanced glass into customer offerings. All Weather Group’s co‑CEOs noted that the collaboration would help the company meet Canada’s stringent energy‑efficiency standards and expand its product portfolio.

The building‑materials industry is increasingly focused on energy efficiency. Quadruple‑pane windows, enabled by Enlighten™ Glass, represent a new benchmark for thermal performance, approaching the efficiency of insulated walls. The partnership positions Corning to capture a growing market for sustainable construction solutions and reinforces its strategic diversification into high‑margin building‑materials products.
