What is a casement window & why are they so popular?
You can find a detailed description on Wikipedia, but a simple description of a casement window is that the casement is the part of the window that opens.
The opening section has hinges on the sides and it can open outward from the left, or from the right, depending on your preference.
A typical casement window “set” can have more than one opening section and is very often seen with top openers (which technically are “awning”). You do not, however, have to make the casement open, it can be a fixed window set (such as a picture window).
Reasons casement windows are popular
What makes this style a favourite in the UK is the combination of factors most people are looking for, which are usually:
- 2024 Prices – uPVC Casement windows prices are very competitive and some good deals are in the market.
- Availability – there are so many sources to buy them from.
- Appearance – slimline frames, different finishes and lots of colour options.
- Flexibility – you can use a casement window almost anywhere.
- Energy savings – latest designs offer up to A++ energy rating
- Security – uPVC casement windows are as secure as you can make a window (without adding bars or grilles)
- Life span – it’s undisputed. uPVC Casement windows can last decades with a little TLC.
UPVC Flush Casement Windows
Another design feature proving to be popular is the have flush uPVC Casement windows fitted. This style has the opening window sections “fitted flush” with the frames themselves.
This means that the whole surface of the window and frames are flat – in other words the opening section is not “raised “as in a standard casement design.
These flush-fit designs give the whole window unit a very sleek and slimline appearance ideally suited to those who want a more “modern-look”.
What factors affect the cost of UPVC casement windows?
The more obvious elements that affect the cost of casement windows are:
Size
It won’t come as much of a surprise that a big window costs more than a small window, but within the obvious, there are sub-factors.
Extra wide individual sections within the frame could incur some kind of “one-off” charge if it means the frames have to be additionally strengthened or modified to cope with the demand of the design. A non-reinforced frame will have an inherent maximum useful width. So for wide or high picture windows bear this in mind.
Frame specification
In general, higher performance specifications for a upvc frame will have a higher initial cost attached. The things that are important to have are good weather seals, good thermal insulation properties, strong internal window beading and reinforced frames.
The corner joints for upvc frames and casements are “welded” together. Poor quality welding will eventually lead to frame distortion and separation of the joints at the corners. When this happens you get leaks and problems opening and closing the windows.
Trickle vents are also an important feature of the frame as they help to combat condensation – trickle vents are sometimes charged as an extra.
Opening Sections
It’s quite common for suppliers to add a charge for each section that opens. This is because there are manufacturing and installation costs for the supplier to make and fit the opening section. So, therefore, it is reasonable to expect the cost to be passed onto the purchaser (you!).
Glazing & Glass
Unless it is an internal window, forget single glazing. Double glazing is the usual standard and triple glazing can be used if you feel the need for it. Everybody knows double glazed units have an “air-gap” (actually it’s a vacuum or filled with gas) between the outer & inner pane. But you may not be aware that the width of the gap can be varied.
The “air-gap” size can run from around 6mm up to just over 21mm with the wider gap units usually having a higher cost. If you fill the gap with an energy saving gas (Argon) you can expect that to add to the initial price also.
Different glass types have different price points. Glazing with Tempered, laminated, Low emissivity, patterned, leaded, frosted or otherwise “special” glass will impact on pricing.
Colour & surface finish options
White upvc casement windows are hugely popular, but there are options to choose another colour. A decent supplier will normally have a choice of about 10 to 15 colour options.
As well as changing the colour you can also opt to have the surface finish of the upvc to be “wood grained”. This option mimics, to great effect, the look and feel of a timber window.
Expect a “premium” of between 10 & 20% for colour and woodgrain.
Types of material used in the manufacture
A standard upvc casement window will be made from an extrusion of, impact resistant, modified acrylic Unplasticised Poly-Vinyl-Chloride, formed into individual multi-chambered sections.
If the UPVC sections have been made by reputable manufacturers, then they will meet various British Standards and be “Kite marked”.
Good quality upvc will have been tested for:
- colour shift
- sound insulation
- thermal conductivity
- heat reversion & heat ageing
- impact resistance
- heat resistance softening point / elasticity

How long does it take to fit uPVC casement windows for a 3 bed-semi?
Of course, it will finally depend on the individual circumstances of your property. But assuming that there are no snags then, from the time they arrive with the windows, a competent team of installers can fit 8 to 10 windows in around 3 or 5 days. This will include “making good” around the new windows and removal / disposal of your old windows.
PLEASE NOTE:
If you are replacing any type of Sash window with a casement window style, then there will be more work (and more expense) involved in “making good” because old sash window frames are much bulkier that new slimline uPVC frames.
If you were worried about having to move out of your home whilst the work is being done, there is no need to do so. A professional team can do the work with a minimum of disturbance (although they will need to come into the house at times to carry out some of the work).
Don’t forget to allow for the time it takes to make your windows. Unless you are buying “supply only” windows that are in-stock, you should allow from 2 to 8 weeks depending on your contractor.
