Leader of the façade segment in Poland – DEFOR's 9th Window & Door Market Leader title
The Centrum Analiz Branżowych ranking is based on the sales results of companies in the building joinery sector. On the basis of 2025 data, DEFOR is closing the 2026 season as the leader of the glass façade segment in Poland. It is our ninth such title since 2017.
The result reflects the scale we have built since 1990: more than 4 million m² of completed façades, more than 100 projects across Europe and the USA, a 47,000 m² plant in Śrem, and Poland's largest façade test chamber, where we test 10 × 10 m specimens.
The certificate was presented at the gala of the Polish Joinery Forum 2026 (Ogólnopolskie Forum Stolarki) in Łódź and received by Piotr Węglewski, Sales Director of DEFOR. We share this title with the investors, general contractors and architects we deliver projects with, and with the team that designs and manufactures our façades.
