Types of uPVC window

Lots of designs. Popular models include:


  • uPVC sash windows: traditional look, smooth mechanisms, replicate timber appearance
  • Casement: highly heat efficient, very secure, many options
  • Tilt and turn: inward-opening makes cleaning simple, ventilate the room with secure tilt


Range of technical, structural characteristics, such as:


  • Glazing: opt for triple glazing for warmth and energy efficiency
  • Framing: decide your favourite look – traditional or contemporary, number of openings, panes, Georgian bars (between panes or external), balanced sightlines, etc.


Once you’ve chosen the style, you can then consider finer details. Will you choose two-tone: one colour outside, and another one inside? This is helpful in areas where the council has strict regulations and won’t allow any changes externally, or when you have rendering or brickwork you want to match, which is different to your internal decor. Possibilities include:


  • White
  • Cream
  • Grey
  • Black
  • Brown


Woodgrain finishes in any shade give more of a timber frame look, ideal for particular properties in historic neighbourhoods.

Frequently Asked Questions

Are aluminium windows better than uPVC?

Aluminium is also much stronger than uPVC and can last up to 45 years with little to no maintenance. Lasting between 20-30 years, modern uPVC windows are strong but not as strong as aluminium.

How do I know when my uPVC windows need replacing?

Signs that your double-glazed windows or doors may need replacing include:

  • Leaks, letting water in.
  • They allow excessive amounts of noise in.
  • The uPVC is yellowing or cracking.
  • There is visible damage, particularly to the seals.
  • They are difficult to open, close and lock, or are sticking.
What time of year is best to replace windows?

Your best bet is to plan your window replacement for a time of year when the weather will be warm, ideally in the spring or early summer.
