What Double Glazed Windows Styles Can I Choose From?
Double glazed windows come in a range of materials and styles. If you want basic double glazed windows, you have casement windows and French casement windows. Tilt and turn windows and sliding sash windows have great features and help maximise restricted space. Bay and Bow double glazed windows let in greater amount of sunlight than any other style. Roof windows are useful if you want additional illumination in an otherwise dark room.
These double glazed windows cover a full spectrum of features. As a result, you can always find the right style for your needs. However, this is only possible if you know what each style is and what it offers. This is why we’ve put together a simple guide to double glazed windows styles. You can learn more about each style and what it offers.
What is a Casement Window?
A casement window is a basic window with hinges on one side. The hinges are attached to the frame. To open the window, you simply swing it out. The traditional form has hinges on one side of the frame, but it’s also possible to have them on the top or bottom. In this format, the window swings open from the bottom or top instead of the side.
These are extremely affordable double glazed windows due to their non-fussy design. They are also one of the oldest styles. In fact, before the sash window gained popularity, this was the most used window style in the UK. This uncomplicated window used to be fitted on to a wooden or stone frame. Today, you can get this elegant double glazed window style in uPVC, aluminium, or timber.
What is a French Casement Window?
Traditionally, casement windows only had one sash. This means they had a single ‘door’. This was attached to one side with hinges. French casement windows, on the other hand, have two ‘doors’ attached on either sides of the frame. As a result, you can open one or both of them. When closed, their swinging ends meet at the centre.
Traditionally, there used to be a vertical pillar or mullion in the centre. The two sashes would sit flush with it on either side when shut. However, modern homes need a fire escape and the wide French casement double glazed windows are ideal for it. Also, the pillar in the middle of the wide opening only obstructs the otherwise unimpeded view.
For this reason, the flying mullion replaced the static pillar. The central pillar is now fixed on to the slave sash.
The advantage of this is that the master sash opens independently. If you want only one sash open, you can do so. However, when you open both sashes, the flying mullion swings out with the slave sash’s opening edge. As a result, you can an unobstructed aperture. This wide opening is great for ventilation as well as a point of escape in case of fire.
What Are the Benefits of a Casement Window?
Of all the double glazed windows styles, casement windows are the cheapest. If you are on a limited budget, these might be the windows for you. French casement windows also give you a wide aperture that doubles as a fire exit. As a result, you can fulfil an important requirement of the building regulations if you install one on each floor.
Additionally, these classic windows suit any architectural style. They are versatile and high performing. Moreover, because the style is so simple, it’s appeal is timeless. In fact, you also get smooth performance for years because of its extremely basic mechanism.
What is a Tilt and Turn Window?
As the name suggests, tilt and turn windows have two ways in which they open. You can tilt these double glazed windows inwards to open them vertically from the top. Alternatively, you can also open them horizontally by swinging them inwards. As a result, you can control both the direction and extent of the opening.
The dual opening mechanism activates when the windows are completely shut. Once closed, the hinging mechanism on the side locks in. As a result, you can pull them open like casement windows. When you want the top opening, simply shut them again. Then, swing them in using the handle on the top edge.
When you tilt them open, you get a restricted aperture. This gives you controlled ventilation. On blustery days, you can open these double glazed windows up a crack. This way, you let in fresh air without blowing everything away. Similarly, on hot days, you can tilt them open further to let in more air.
It is also more secure since the opening isn’t wide enough for an intruder to squeeze in. What’s more, you can crack them open for ventilation. However, from the outside, your windows appear to be shut. You can tilt them all the way in so they lie flat. As a result, you can clean the outer pane without any risks.
When Should I Choose Tilt and Turn Windows?
The tilt and turn double glazed windows are ideal for properties on higher floors. They are even more useful if you have little children or pets. Since the windows open from the top, you can get fresh air. However, your little ones won’t be able to access the opening.
Moreover, since you can lay them flat to access the outer pane, you will find it easier to clean your windows. Simply open them all the way. After that, you can sit in the comfort of your home as you wipe them clean. No more hanging out of the window, risking a fall!
Additionally, you should consider them if your window apertures don’t have much space outside. Since they swing open inside, you can get ventilation even from windows that are in tight spaces.
What are Sliding Sash Windows?
Even if you don’t know what sliding sash windows are, we are confident that you must have seen them. You can see them on almost every heritage property. They have a unique opening mechanism. Unlike other double glazed windows, this style slides up vertically on rollers to open. It does not have hinges or tilting mechanisms.
Having said that, it’s important to note that modern sliding sash windows do have a tilting option. However, this is for easier cleaning rather than a window opening feature.
Sliding sash windows have two parts – A fixed sash on top and a sliding sash below which slides up behind it when open. A traditional sash window would have a sash horn. This is a little fixture that supports the window when it’s open. Almost all traditional sliding sash windows have Georgian bars. Georgian bars are the crossbars you see on windows. The glass pane is broken up into smaller segments. These are set inside smaller individual frames.
What are the Features of Sliding Sash Windows?
Sliding sash double glazed windows are a requirement for most heritage properties. This is because these properties cannot have fittings that change their external appearance. Even if you don’t own a heritage home, these windows add an old-world charm to any architectural style. Even modern homes can use these double glazed windows for a quirky touch.
Sliding sash windows provide a large opening for more sunlight. Once open, they give ample ventilation.Sliding sash windows also optimise your interior space. Since they don’t need room to swing open, you get more usable space around them.
What are Bay and Bow Windows?
Bay and bow styles are large double glazed windows. These are a design feature in themselves and often become the focus of the room. These double glazed windows are made up of multiple facets around a central panel. There can be anything from 3 to 7 panels in one of these windows. The panels are arranged at a fixed angle from each other. As a result, the windows are curved, and projecting out from the wall.
Due to this projection, these double glazed windows give enhanced natural illumination. They also give a sense of being out in the garden without actually going out. This makes them ideal for garden facing walls where you want to show off your horticultural skills.
What is the Difference Between Bay and Bow Windows?
While bay and bow windows look similar, there is a technical difference between them. Bay windows are set upon walls that are shaped specifically for them. This means they have as many facets as the window itself. Bow windows, on the other hand, can be fixed on straight walls.
This is because these double glazed windows are set upon a ‘shelf’ that is shaped to hold the window. Also, they have a gentler angle making them appear ‘bow-shaped’.
As a result, bay windows can only be fixed on properties that were designed for them. Meanwhile, bow windows can be fixed in any large aperture. However, they both offer the same set of benefits.
Why are Bay and Bow Windows the Best Choice for Me?
If you have a beautiful garden and want to enjoy it regardless of weather, you will love bay and bow windows. Even if it is pouring outside, these windows make you feel like you are outside. The large double glazed windows make any room appear brighter, and thus bigger. As a result, they can often become the architectural focal point for the room.
These double glazed windows are perfect if you like grandeur. You can easily add Victorian opulence to your home with these windows. Moreover, they can serve as a cosy window seat or a naturally lit nook where you curl up with a book.
What are Roof Windows?
Roof windows, as the name suggests, are double glazed windows installed on the roof. These are usually used on tiled or solid roofs to let in more natural light. Roof windows can be flat or raised. Raised window roofs, or roof lanterns are extremely popular. They serve both as a design feature, drawing the eye upwards, and an illumination point. These windows are especially useful for tiled roof conservatories for more sunlight.
Flat double glazed roofs may not be as stylish as roof lanterns. However, they work beautifully if you want the sunlight pouring in a room that can’t have regular double glazed windows.
Should I Get Roof Windows For My Home?
If you have a room that cannot have windows on the walls, roof windows should be ideal for you. Even if the room has standard double glazed windows, you might want additional illumination. This might be the case if the room has a wall or another property blocking the light. These double glazed windows also work well in lofts or attics.
Additionally, you can also take advantage of the additional ventilation these double glazed windows might offer. You can fit them with a manual or an automated opening system. This way, you can open them whenever you want for fresh air circulation.
However, even if you don’t need extra light or air, these double glazed windows on your ceiling can be a good way to look at the stars at night. Install them in your bedroom and you can look up at the night sky while you’re in bed.
