Explaining aluminium windows designs
There are two areas to understand with aluminium windows designs. First of all is the design of the window frame itself. Most quality aluminium windows, come with several frame options. So whether you’re looking for a flat and modern frame, something with a shape or sculpture to it or even something close to a traditional timber or steel window, aluminium windows designs do cater for most requirements.
Also covering aluminium windows designs is the overall look of the window. What are the sizes, how many fixed or opening elements are required? Are you looking to retain the look of original windows or change the appearance of the property with something more modern? The answer to this is aluminium windows designs are virtually unlimited. There are only a few factors affecting types of aluminium windows.
- The maximum sizes possible based on technical, structural, security or safety reasons
- Sizes based on minimum or maximum tolerances
- Limitations due to handling or transportation
An excellent example is how large an opening element of a hinged window can be. Most aluminium windows only go up to around 1.2m or 1.5m with side opening windows even smaller at 600mm or 900mm. So you won’t find extra large opening windows beyond these sizes.
Another example is floor-to-ceiling windows or large picture windows. These are usually available up to the maximum size of the glass. Compared with timber or PVCu windows, aluminium does give you both smaller as well as larger windows, bigger glass sizes and slimmer frames.
Opening types of aluminium windows
Most people expect their windows to open and close. With aluminium there are several aluminium windows designs based on the opening method. Here are all the various opening methods for aluminium windows. However, do bear in mind not every aluminium window brand comes with these opening options. You can contact us for information if there’s a particular window style you’re after.
Top hung opening out windows
The top hung opening window offers convenience with the hinges on the left and right sides and the window handle at the bottom.
Opening outwards this window suits more modern types of aluminium windows as well as windows designs having larger glass panels and fewer dividing mullions and transoms. The benefit of top hung opening out windows is they come at larger sizes than side hung windows.
The are two potential drawbacks to this window. One is it’s not convenient placed over a kitchen sink, as reaching to close the window is hard. Another is these windows at ground floor level or opening onto pathways may need restricting to avoid injury.
Side hung opening aluminium windows designs
Popular with traditional or modern homes is the side hung design. Here the window hinges from the top and bottom with the window handle on the side.
The advantage of these windows is flexibility and safety. Easy clean hinges slide the open window along its frame letting you clean the outside pane of glass from inside the room. Fire-escape hinges allow suitably-sized windows to open out to 90 degrees.
The drawback to this window is it’s restricted by size. Most side hung types of aluminium windows only go to around 600mm wide with a handful of products slightly wide. They’re also frequently restricted on height.
Tilt and turn opening windows
One of the most flexible and convenient windows are tilt and turn windows. Operated by a multi-functional handle, they have two opening options. One is where the window tilts inwards from the bottom for ventilation. Then, closing the window and rotating the handle in the opposite direction allows the entire opening element to swing into the room.
The first benefit is cleaning the outside pane of glass from the outside. the other is allowing larger opening vents than side hung or top hung windows.
Tilt and turn windows won’t be for everyone. The more complex gearing means window frames are thicker than side hung or top hung versions. The advantage of tilt and turn is coming at significantly larger sizes. In fact it’s possible to get tilt and turn windows are virtually the size of a door. As a result, they’re ideal for windows leading to a flat roof or a Juliet balcony.
Sliding types of aluminium windows
There are two sliding types of aluminium windows and these are vertical or horizontal sliding.
The vertical sliding design replicates the look of traditional sash windows with the obvious solution these provide in homes with existing sash windows.
The horizontal design is essentially a cut-down patio sliding door with most products. It’s not as popular as a design although it does allow the largest possible window openings of any
Flush casement windows
The flush casement window is a more recent innovation offering both contemporary or traditional aluminium windows designs. Therefore, they’re ideal for cottages, set into stonework, timber subframes or in a contemporary home.
Smart Systems offer one of the slimmest, as does the aïrMOD system. Thicker versions come from Origin, Stellar, Decalu and other brands.
Other types of opening windows
Whilst not as popular with dwellings, there are other opening types of aluminium windows and designs. These include, reversible windows, parallel opening windows or inward opening windows.
You can also find combinations of window designs such as opening outwards windows combined with a tilt and turn. Of course it’s also possible to integrate all these types of aluminium windows within a door screen.
Floor-to-ceiling and panoramic windows
Popular with new extensions, modern homes or high-end architecture and glazing are large panoramic, floor-to-ceiling windows and even curtain walling.
These aluminium windows designs rely on suitable framing and significant expertise by the installer. Only maximum glass sizes determine the sizes possible. Crucially, there are more technical or structural considerations over and above standard window designs such as wind deflection.
These dramatic oversized windows create a statement-piece window but do require a more experienced installer and window manufacturer.
Internal aluminium windows designs and types
Whilst this article concentrates on exterior aluminium windows, there are the same options and choice for windows used internally.
One consideration is exterior grade windows come with thermal insulation and double glazed units. These are two elements not needed inside the home in most cases. Therefore, it’s with considering steel look or internal window products with brands such as Aluco or a dedicated interior window with single safety glass options.
Single glass creates a better overall look than double glazed windows where you don’t need specific sound or insulation. Internal single glazed windows are also slimmer in most cases.
How to choose the right window opening type
The choice of buying the right window comes down to your property type, whether you’re replacing existing windows or need new windows for a building project such as a new extension.
- Research as many aluminium windows brands as possible, to understand the options available.
- Consider safety as well as security such as a means of escape
- Whilst the slimmest windows are desirable, they don’t all offer the required functionality
- Fewer options exist for internal aluminium windows designs
