How the humble uPVC window came to be the norm.

Since its emergence in the 1970s, uPVC has proved to be one of the more popular materials to use for windows, doors, conservatories and secondary glazing. Its has been hailed for being lightweight, durable and extremely strong, and it’s also cheaper to produce than the traditional timber we used to see. Today most of our houses have uPVC to enhance and protect our homes, but how did this revolution come about?

With property prices increasing in the UK, uPVC was first introduced in Germany when replacement windows were in fashion. Whereas aluminium had ineffective thermal break structures which made the frames produce condensation, especially during the winter months, uPVC created more protection. A number of window designs were available, albeit without much style, from Georgian-style windows to uPVC outward opening windows and wood grain designs. Similarly, uPVC moulded door panels came on to the market and offered customers a huge selection of jelly-mould styles to replicate timber doors.


By the late 1990s many manufacturers of uPVC offered softer designed frames and better-quality security choices for internal windows. Black gaskets which were fitted outside the glass were rejected by the public for being too ugly, so a change came about whereby white gaskets were introduced. However, their popularity was short-lived when people realised that too much grime and dirt collected on them and people returned to black gaskets for their Double Glazing in Gloucester, Cardiff, London or wherever they lived.

This was the decade when things really took off for the glazing industry. People started to demand windows that were of top quality, maintenance-free and, more importantly, didn’t give the impression they looked like they were made from uPVC. Homeowners were able to replace their windows with the help of companies and still achieve the look of timber windows, without the hassle of having to keep them maintained. With all this choice available for the homeowner, a report by Global Market Insights Inc suggests the production of doors and windows is set to reach 47 billion within the next 10 years.

Nowadays, the combination of precision in manufacturing, elegant finishing and colour options has improved the shapes and designs of the replacement window. Whether you have a country cottage, Victorian house or a new-build, there’ll be a uPVC window to suit your property without losing the style.
