Carlisle Window Systems, a business that has grown from a small local installer into one of Cumbria’s leading window and door specialists, is celebrating 30 years of partnership with Eurocell.

Carlisle Window Systems has been manufacturing and installing Eurocell systems, including Logik and Modus.

The relationship is said to be built on shared values of reliability, technical excellence and long-term collaboration. Eurocell’s support – from specification guidance and U-value calculations to building regulation advice – has been central to Carlisle’s growth.

Liam Kelly, managing director of Carlisle Window Systems, said:

“Our growth over the last 30 years has been built on strong, long-term partnerships, and Eurocell has played a key part in that journey. Working with a supplier that consistently supports us with technical expertise and shares our values has been fundamental to our success”

“In particular, the support and expertise of Stephen Greaves, North East technical engineer, has been invaluable. His knowledge and commitment over the years have played an important role in helping us achieve the position we’re in today.”

Tony Morrison, head of national key accounts at Eurocell, said:

“Carlisle Window Systems is a fantastic example of what long-term investment, family values, and strong partnerships can achieve. We’re proud to have worked alongside them for decades and look forward to supporting their continued growth in both PVC-U and aluminium.”

Through this partnership, Carlisle has expanded into new markets, including timber frame projects using Eurocell’s InSite window system. This factory-fitted solution allows fully finished windows to be installed directly into panels during production, reducing labour, speeding up build programmes, and ensuring a wind and watertight structure from day one. Recent developments also include aluminium bi-folds, sliders, and windows, as well as a commitment to sustainability through Eurocell’s recycling and waste take-back schemes.

Led by father and son, Jock and Liam Kelly, Carlisle Window Systems remains a family-run business at its heart. Eurocell is proud to support a partner that also gives back to its community, recently exemplified by a project with Chrysalis – a local Carlisle charity supporting young adults with disabilities – where windows and doors were supplied and installed free of charge on its setting.
