Armstrong Industries reports 10% sales growth in 2025

Armstrong Industries, a leading manufacturer of PVC-U and aluminium windows and doors, has reported a 10% increase in sales for 2025.

According to Armstrong, the growth is closely tied to the company’s continued investment in the Kömmerling product range, including the chamfered, ovolo, and full flush casement and door systems. These profiles have reportedly allowed Armstrong’s trade partners to elevate their product offerings, expand into new design sectors, and deliver the modern aesthetics homeowners increasingly demand.

The full flush casement system, in particular, is said to have proven to be a stand-out success, thanks to its clean sightlines and premium finish that have given installers a high-value product with broad consumer appeal.

Armstrong says that its customers have been able to differentiate themselves from lower-spec competitors and secure additional market share throughout the year.

In addition to profile innovation, Armstrong Industries’ in-house profile paint system has become a decisive advantage for customers looking to offer something unique. Unlike standard foil options, Armstrong’s paint technology allows installers to provide truly bespoke finishes – including contemporary matte tones, heritage shades, and custom architectural colours.

This capability has opened new opportunities for installers who want to position themselves at the premium end of the market. Many customers have reported winning jobs specifically because they could offer colours and finishes not available elsewhere.

According to Armstrong, the combined strength of Kömmerling profiles and a bespoke colour offering has directly contributed to the company’s year-on-year growth. Installers who adopted the expanded range early in 2025 have reported ‘noticeable uplifts’ in enquiry volumes, average order values, and conversion rates.

As Armstrong continues to invest in new machinery, streamlined manufacturing, and customer support, the business fully expects further growth into 2026. The company invites trade partners, installers, and industry professionals to ‘experience the 10% difference themselves’ by exploring the Kömmerling range, visiting the Armstrong factory, and discovering the full potential of its colour technologies.
