Our History


Haydn started South Wales Windows in 1990 after growing a wealth of experience in the industry selling windows and doors through the 1970s and 1980’s. Haydn started off with a humble office and show room on Woodville road building our reputation for fair prices and great products from the offset.


With our reputation growing alongside our range of product and services. A larger team meant a move to City Road Cardiff, to fulfil demand create a new improved showroom and one of the first in area of its size and range.


After 5 years of continued growth and demand for our services we made the move to start manufacturing. Needing a larger premise than before we settled in Taffs Well and remained there for over 20 years.


Haydn’s daughter Catrin begins working for the company. Initially to help with admin Catrin quickly developed into a management role helping Haydn manage the busy day tasks and becoming a pivotal member of team.


The next big move sees us growing our team and gearing up to celebrate our 30th year of trading. Locating to Treforest to open a large showroom for customers to browse products and chat with us about their needs. Haydn now into his 70s works part time with Catrin who has worked beside him for more than 10 years now working as director alongside her husband and close friend.
