Software provider, Forterro, has announced its intention to acquire Klaes, a globally recognised software specialist for windows, doors, façades, and conservatories.

Following last year’s acquisitions of Orgadata and BM Group, the addition of Klaes represents another significant milestone in the expansion of Forterro’s Windows & Doors line of business, combining trusted industry software across aluminium, PVC and wood while advancing cloud and AI-driven innovation.

Founded in 1983, Klaes is a family-owned company and specialist in software solutions for windows, doors, façades and conservatories, now active in more than 50 countries worldwide.

The company is known for digital tools such as the Klaes premium ERP system, the flexible production control solution e‑prod, and highly specialised 3D solutions for façade construction.

While market‑leading software Logikal (formerly Orgadata) remains a leading solution for aluminium systems, Klaes contributes extensive expertise in PVC and wood. The former BM Group, with its strong footprint in the UK and Irish markets, further complements the portfolio with specialised software for the residential segment.

Dean Forbes, CEO of Forterro, commented:

“With Orgadata, the BM Group and now Klaes under one roof, Forterro supports all key materials and production processes in the sector. Through intelligent, increasingly AI‑powered solutions, we enable manufacturers to digitalise their processes faster and more effectively than ever before.”
