Ask anyone who remembers Irish homes in the 1990s to picture uPVC windows, and they’ll probably describe the same thing: chunky white frames that yellowed in the sun and looked like a poor substitute for the timber windows they replaced. That reputation was earned. uPVC only arrived in Ireland in 1986, and the early frames could discolour, turn brittle and crack after a few years of weather.
Forty years and four generations of development later, the material is almost unrecognisable. The best uPVC windows now keep heat in far better than the building regulations require, lock at multiple points around the frame, come in everything from oak woodgrain to ultra-matt black, and need little more than a wipe down to stay looking new. That combination is why uPVC windows have become the most popular choice in Irish homes.
This guide tells that story: how uPVC changed, what it does well today, how long it lasts, and how to decide whether it’s right for your home.
