Continuous Growth

Stable partner to grow your business


Glass Systems was established in 1988 in Swansea comprising of one manual IGU production line. Since our creation, we have been driven by a clear vision, to give our customers what they want, when they want it, and at a fair price. In the early 1990s, a customer base was estab­lished in Wales and along the M4 corridor to London.


of Glass Systems history

  • 1996

    The subsequent years saw an in­crease in business, and the need to toughen our own glass, which resulted in the setting up of our own in-house toughening facility known as Vizor Tempered Glass Ltd.

  • 2003

    Our expansion continued, and in 2003, a move to a purpose-built factory in Swansea and the investment to automate many of the processes became a necessity. This 50,000 sq. ft. purpose-built factory set up with three robotic Sealed Unit lines, two autoloading cutting lines and three spacer bar benders, now has the capacity to produce almost 30,000 Sealed Units per week. This combined with the latest state-of-the-art electronic ordering, optimisation and planning software meant, that we could expand into Southern and South East England.

  • 2007

    In 2007 we acquired a factory based just north of Cardiff. This site was remodelled based on the flagship site in Swansea to provide a common brand for Glass Systems. This gave us further capacity and the ability to service an increased geographical area from South West England to the North West of England.

    Glass Systems Direct is equipped with two robotic Sealed Unit lines, two autoloading cutting lines, an automatic glass arriser and a Cooltemper toughening furnace. Along with our state-of-the-art software, this factory now has the capacity to produce up to 17,000 Insulated Glass Units per week.

  • 2009

    In 2009 we established Climate Glass – a brand-new portfolio of insulated glass units dedicated to the conserva­tory roof glass market. Since then, the brand has been characterised by a number of advanced features increasing indoor living comfort. Over this time the brand’s reputation has continued to grow, significantly increasing users’ interior comfort. Our Climate Glass products are offered within our Advanced Glass Options range.

    The model of services offered to customers by Glass Systems, and the introduction of Climate Glass, kindled an increasing interest of new customers. As a result, the company invested again to give current and prospective customers exactly what they want, when they want it, and at a fair price.

  • 2010

    Thanks to our customers’ trust in us and our values, in 2010 we have become the leading producer of insulated glass units for the fenestration industry, with the biggest share of the UK’s market. Since then our custom­ers further benefited thanks to the continuous increase in our stability and capacity. This in turn has assisted our customers in their business growth.

  • 2014

    In 2014 Glass systems invested in a new 40,000 sq. ft. purpose-built factory in Peterborough. This had been strategically placed just off the A1 Motorway to supply Insulated Glass Units into Essex, Norfolk, Suffolk, East Anglia and South Yorkshire. The site is equipped with three robotic Sealed Unit lines, three cutting lines and a Tamglass 2448 Pro Convection Toughening furnace. The site has been built to produce over 20,000 Insulated Glass Units per week.

  • 2015

    In 2015 we became a part of the globally active Press Glass Group, the largest independent IGU manufacturer for the construction and window industry in Europe. This meant that we became a part of a wider family and a global organisation. We started a process of merging our values, ad­vantages, and methods of operation to give more benefits to our clients.

  • 2017

    In 2017 we acquired two factories from the Pilkington organisation, one in Barnsley and the other in Scotland. Our vision was to invest and to grow both sites to strengthen our share of the UK market and to provide national coverage.
