About us
CalWin is the timber products industry's own IT company and is owned by leading firms in the industry in Norway. The company was established in 1985 to develop an IT solution for window and door manufacturers. Today we are the leading supplier of IT systems to this industry in Norway and Sweden, and with a growing position in the UK.
Used by companies all over Europe
Over the years the software has been expanded to contain functionality in all areas that are special for this industry and not catered for in general ERP systems. Today, CalWin proudly serves numerous companies across UK, Scandinavia, and Lithuania, solidifying its reputation as the go-to solution for window and door manufacturers. Our UK office is located in Newcastle upon Tyne. CalWin Ltd is characterised first and foremost by its thorough knowledge of the industry. We have in-depth knowledge of windows and doors and are regarded as skilled and experienced advisers and consultation partners for manufacturers and other players in the industry.
Local presence in Sweden
In September 2025, CalWin opened its own office in Uddevalla, Sweden—an important step in our growth strategy and a natural progression driven by an ever-expanding customer base in the Swedish market. A local presence enables us to offer closer follow-up and support to our Swedish customers, strengthen existing collaborations, and build new partnerships within the Swedish door and window industry. The office is headed by Håkan Torsson, who is based in Uddevalla.
CalWin represented in the Baltics
CalWin established a Lithuanian subsidiary and hired a local consultant in 2019 as a first step toward strengthening its foothold in the Baltic region. We are the perfect partner for manufacturers in the Baltics seeking specialized software for the door and window industry.
