There isn’t a single answer to the uPVC thickness question. uPVC windows are very adaptable and can be customised in almost any way you so wish. It may not be the answer you were looking for, but it does, however, provide you with greater flexibility in terms of choosing the right uPVC window for you and your home!

There has to be some thickness within a uPVC system, simply due to the fact that there is great engineering involved in its production.

Double glazed windows are fitted with two panes of glass and a space of around 12mm – 16mm between them. The gap is held in place with a spacer bar with either normal air or argon gas. Because of the gap and the glazing itself, the standard thickness of a uPVC is of around 20mm – 28mm.

Some customers can be put off by the bulkiness of uPVC windows, but not all of them are as thick as the standard size…

Is there a thinner uPVC window frame available?

The simple answer, yes!
