Specialised or Bespoke uPVC Casement Window Designs
Flush Fitting uPVC Casement Windows.
Many homeowners are now choosing to install “flush fitting” casement window designs for their clean lines and modern look.
A normal casement window opening section, when closed, will have a frame that sits “proud” of the main window to which it is attached – in other words the opening window gives a raised profile to the appearance.
With flush fitting casements, when you close the window it sits completely level with the outer main window frame and gives a completely flush surface with no raised sections.
Flush fitting casement windows are not a new idea; they were very popular way back in the 19th Century, well before “lipped” windows became the more prevalent design, sometime in mid-1950’s Britain, but are now making quite a resurgence.
Reversible UPVC Casement Windows
By means of specialised hinges, the reversible window can be opened in such a way as to effectively spin the window through 180 degrees so that the outside of the window can be easily accessed – great for upper floors or apartment windows.
There are two other popular specialised design variations and these are always made to order and therefore you can refer to them as bespoke products, and they are;
UPVC Bay Windows & UPVC Bow Windows – both of which can make use of the casement as primary design influence.
Bay and Bow windows are “projection windows” in that they extend outwards from the property. Bow windows extend outwards in a gentle curve, whilst bay windows extend in an angular fashion.
In this way, both the Bow and the Bay add extra space to the room. Read more about bay windows.
Personalising your new uPVC Casement Windows
There are a lot of things you can do in order to make your new windows look even better. From choosing different colours, to the type of glass or even what type of surface finish to use, is all open to variation – here are some of the options available.
There are 2 ways to achieve colorisation of uPVC, the first is via a spray paint coat, the other is by a process known as foiling (more about colours here)
Spray paint coats are just that – a coat of paint sprayed on, but with additional heat treatment. This is best done in the manufacturing process; however, you can have them sprayed after installation by specialists.
Foiled UPVC Casement windows go through the process at the factory and it involves adding coloured film to the surface of the uPVC and treating it under heat & pressure to bond it to the surface. Foils are very durable and resistant to peel, flake and fading problems.
Glass & Glazing Options -1) appearance
For sure you will be fitting your new windows with double glazed sealed units as standard, but you can choose the style of glass that goes into the unit.
Plain glass is obviously the most popular choice, but you can add decorative features such as “lead” strips, coloured glass and patterned or obscure glazing.
Frosted glass is used mainly to offer a high degree of privacy for bathroom, shower or toilet windows.
Glass & Glazing Options – 2) energy efficiency & security
As we mentioned above, double glazed sealed units for uPVC Casement windows come as standard. In order to get even more energy efficiency, you can add some or all of the following options.
- Low emissivity glass – can be fitted to one or both panes of the double glazed unit
- Argon gas filled cavity – the space between the double glazed panes can be filled with gas to lower heat & cold convection.
- Warm edge spacers – these are the strips inside the gap that keep the panes separated. Using warm edge spacers reduces heat transfer.
- Triple Glazing – whist it does cost more, using triple glazing increase energy efficiency “across the board”.
In terms of security, in general, a double glazed sealed unit is quite difficult to break without applying a good deal of force, however, by adding toughed glass it will make the window significantly more secure.
Toughened glass can be used on the outside, inside or both sides of the window.
One step up from toughened glass is laminated glass. Exceptionally strong and safe, but it does come with quite a significant price increase over both toughened and standard glass.
There are 2 main options when it comes to the finished surface of the window – smooth or wood-grain. Smooth surfaces are the standard finish for the average casement window.
As mentioned previously, uPVC can feature coloured foil finishes however, these foiled finishes can also be textured to recreate the look and feel of genuine timber-grain.
Foiled wood-grain finishes give your windows amazing visual appeal, and are bonded into the surface of the uPVC.
Wood-grains are designed and applied in such a way that they don’t peel, crack, shrink, fade or otherwise deteriorate like a typical coat of paint.
UPVC Casement Window Furniture (hardware)
The furniture, or hardware, for windows really refers to the type of locks, handles or hinges fitted and there is an extended catalogue from which to choose.
For example, you may see reference to handles with a spur, a spade, a spindle, espag or even a fork. All of these window handles will have a key lock fitted.
- Cockspur – a simple straight handle
- Cranked – has a small offset in the line of the handle
- Monkey tail – a handle with a curly section at the end (looks like a monkey tail!)
Check with your installer to see which types of handles they stock.
You can also fit movement restrictors, which allow you to partly open the window whilst preventing further opening from both inside or outside (keeps out unwanted guests).
Restrictors are also useful if you have children at home to add a precautionary safety feature.
