About Incarnation Window Systems

Incarnation Window Systems was originally formed as a part of the UK’s leading uPVC sash window manufacturer Roseview Windows.

As a sash window manufacturer Roseview is involved in supplying windows for hundreds of heritage, conservation and renovation projects each year. However, it became clear that – despite the quality and price of Roseview’s Windows – there were always going to be a range of jobs where original windows simply couldn’t be replaced. From listed buildings to huge hotels and hospitals, there are lots of buildings out there that are desperate for the the benefits of double glazing, but for anything from conservation to budget reasons simply cannot install new windows.

So we started manufacturing aluminium secondary glazing, initially to help a specific customer fulfil a project that required both replacement sash windows and secondary double glazing.

We started off small – tucked away in a corner of the main factory – but soon it became clear that there was plenty of demand for secondary glazing from our existing sash window customers. So steadily we grew, taking on more projects and supplying more customers, until now we’ve moved into our own dedicated factory unit and set ourselves up as a new, separate company.
