Forterro acquires German-based software provider Klaes

Forterro, a European software provider for the industrial midmarket, is set to acquire Klaes, a software specialist for windows, doors, façades, and conservatories.

Following last year’s acquisitions of Orgadata and BM Group, the addition of Klaes is said to represent another significant milestone in the expansion of Forterro’s Windows and Doors line of business, which is says will further strengthen the company’s position as it strives to become one of the market’s leading software providers across all materials.

Combining Expertise to Better Serve Customer Needs

Founded in 1983, Klaes began as a one‑man operation, and has grown into a family-owned company in software solutions for windows, doors, façades and conservatories, now active in more than 50 countries worldwide.

With digital tools such as the Klaes premium ERP system, the flexible production control solution e‑prod, and highly-specialised 3D solutions for façade construction, Klaes says it is deeply integrated across all operational areas of the industry.

From its headquarters in Bad Neuenahr-Ahrweiler, Germany, the software house helps companies of all sizes to operate efficiently and remain competitive.

The move under the Forterro umbrella is seen by Miriam Berzen, one of the Managing Directors of the company, as the beginning of a new phase of growth and performance.

She said: “Joining Forterro marks an exciting new chapter for Klaes. For more than four decades, our mission has been to develop innovative and reliable solutions that help manufacturers in the window and door industry stay competitive and prepared for the future.

“We gain the strength and resources of a European market leader while retaining the passion and customer proximity that have defined us since our founding in 1983.”

With the acquisition of Klaes, Forterro is consistently pursuing its ambitious expansion strategy within the window and door sector. While software Logikal (formerly Orgadata) reportedly remains the benchmark 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.

Forterro says the strategy behind this move is clear: positioning itself as the leading material‑agnostic partner for the window and door industry, bringing together one of the strongest cross‑material portfolios on the market.

By combining complementary capabilities across aluminium, PVC and wood, the group now supports the entire value chain – from configuration and calculation through to production and installation.

This integrated approach enables manufacturers of all sizes to streamline workflows, optimise processes and accelerate their digital transformation, while further strengthening Forterro’s footprint in craft and manufacturing software across Europe.

The shared objective is to make Klaes’s product portfolio even more powerful and future‑ready. Together, the partners will invest heavily in cloud platforms and AI‑driven innovations to significantly accelerate digital transformation across both skilled trades and industrial manufacturing.

By pooling expertise within the Windows & Doors business unit, innovations in areas such as production automation and advanced data analytics can reportedly be brought to market significantly faster.

Klaes will continue to operate as a strong, independent brand within the business unit. For customers, this step above all means long‑term stability: access to a global network, a shared infrastructure and additional technological expertise to meet future market demands.

Dean Forbes, CEO of Forterro, highlights the strategic importance of the acquisition: “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.”

The acquisition agreement has been signed and is now subject only to completion of regulatory approval reviews, which are expected to conclude in the second quarter of this year.
