There isn’t a single answer to the uPVC window thickness question. uPVC windows are very adaptable and can be customised in almost any way. It may not be the answer you were looking for, but it does 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, due to the fact that there is great engineering involved in its production.

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

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

How to measure thickness of double glazing

The process for measuring the thickness of your own double glazing is easy to do:

  • Start by measuring the distance from the outside of the frame to the inside
  • Take the measurement from edge to edge of the window frame
  • Repeat these steps in several places
  • Your smallest measurement will be the depth that you require

What is the glass thickness on double glazing?

Most double glazed windows use glass panes that are 4mm in depth. So, as there are 2 panes of glass in use, the total window glass thickness is 8mm. However, thicker glass panes are available. Using thicker glass can improve insulation and keep out more noise. If you require these qualities for your home, we can help!
