Pros and cons of large uPVC windows

What is the maximum size of a UPVC window?

uPVC windows come in various sizes to cater to different needs. According to industry standards, a large uPVC window design can have a size of up to 2.65 metres squared. However, custom-made, extra-large uPVC windows can be even bigger, with some manufacturers offering sizes up to 4 metres squared or more.

To ensure you get the right size, it’s important to know how to measure your windows correctly. In the next section, we’ll look at the steps involved in measuring large uPVC windows accurately.

How to measure uPVC windows

Measuring uPVC windows accurately is essential to ensure you get the right size and fit for your replacement windows. It can even determine if the window will achieve the benefits you’re looking for. 

To start, measure the width and height of the window opening, ensuring to take measurements from multiple points to account for any irregularities. When measuring the width, take the measurement from the top, middle, and bottom of the opening, and do the same for the height.

It’s worth noting that some uPVC window sizes are industry standard, so you may not need to measure them. However, custom window sizes are also available, so it’s best to double-check before purchasing. In addition, it’s essential to consider the different uPVC window styles, as this can affect the measurements required.

In the next section, we’ll discuss the different sizes of uPVC windows available so that you can make an informed decision.

What are the sizes of UPVC windows?
