There are many different types of window frames to suit different purposes and tastes. For example, certain designs can be used to provide adequate ventilation, even during tropical downpours, and/or bring more natural light into the home.

Different window styles offer different opening areas, which are of varying importance depending individual requirements. Larger openings increase ventilation options, while windows with smaller openings may be preferred because they provide greater safety.

For many people, energy efficiency and maintenance requirements will be factors to consider when choosing window styles for their homes. Hinged windows, for example, generally have the advantage over sliding windows due to their tighter sealing ability. In contrast, sliding windows are easy to maintain since they require only occasional cleaning of the glass window tracks.

New window styles are constantly being developed, and depending on the type of construction, size of your house, and number of windows in your house, you may consider a variety of styles for different purposes.

The following provides a brief overview of some common window styles as well as the differences in their energy efficiency:

Sliding windows – often have two or more sashes (sliding parts) that move horizontally, and provide a nice, clear opening for good ventilation. They can be double-glazed for energy efficiency, and often are fitted with insect screens. This type of window is relatively economical.

Awning windows – are top-hinged and open outwards. They can be double-glazed, and provide a tight seal when closed, unlike sliding windows. Although more burglar-proof than sliding windows, they also hinder exit in an emergency. This type of window is popular, aesthetically speaking.

Casement windows – are side-hinged and open outwards. They have the energy-efficiency advantages of awning windows but do allow an easier exit. Insect screens need to be internally fitted.

Double-hung windows – may be made from a variety of materials. The sashes move vertically, unlike sliding windows, and are assisted by internally fitted springs. The strength of the spring mechanism may limit the ability to support double-glazing. Insect screens may be externally fitted.

Roof windows (which may be likened to skylights) – are installed to bring light to areas which do not have external walls. They can be double-glazed, opened to allow ventilation if desired, and may be controlled remotely.

Have you ever seen companies talking about plastic versus aluminium, or had someone tell you to invest in a glass window with aluminium instead of polyvinyl chloride (UVC) or polyurethane? It’s not always entirely clear what the difference is between these products, so this article is designed to explain the pros and cons of each and help you make an informed decision.

What are the benefits of uPVC?
uPVC windows are generally a better insulator than aluminium and do not lose colour over their lifetime. They’re also easy to clean and maintain, often just requiring a light wipe over with a damp cloth. They also incorporate a wide variety of colours, with some retailers offering a wood imitation effect that looks classy without costing too much.

These windows are a sound investment as they don’t fade, warp, rot, or peel. If maintained correctly, they can last up to 20 years.

What are the benefits of aluminium?

Aluminium tends to be stronger than uPVC, which means that aluminium windows can have a slimmer appearance and a larger glass surface due to the strength of the frame. These are very popular in commercial and public buildings and can be useful for homes if you are looking for a particularly large design. Aluminium can also last a long time – up to 20 years if you get powder coating.

Aluminium is more flexible in design than PVC, and the colour range, including the double colours, is amazing. Aluminium windows are designed to withstand extreme conditions, so they are a good choice for your home, office or even your car.

Aluminium windows are also environmentally friendly as aluminium is an endlessly recyclable material, so when you do eventually replace your windows, you can be eco-friendly.

So, which should I choose?

Both options have great advantages, but which option is right for you depends on your individual needs. If you want large windows that are very exposed to the environment, you should go for an aluminium frame. If the windows you need are smaller, and you want something that looks very stylish, uPVC may be the better option. Ultimately, you should always consult with a professional before coming to a final solution.

In the early 1980s, my family had an aluminium sliding door with an aluminium frame that was an ugly metal strip. I remember my mum calling the manager to complain because she didn’t close properly. Aluminium frames have come a long way since then and have become a leading medium for architects to design window frames for new homes.

In modern new buildings, where slim lines contribute to stylish exterior facades, it is subtle what the architect chooses. Aluminium is considered very trendy today, and aluminium doors and windows have come a long way since then.

Aluminium is naturally strong, which means that you can install really large windows and doors without the need for bulky frame supports. In addition, fewer metal elements are needed to hold the glass fittings, making them less susceptible to corrosion and damage.
The fact that you can use more glass is a great advantage for some people, and the glass surface is maximized to give the best possible aspect. Most of the windows will be glass and not frames, but there will also be a much more modern look, as the viewing direction is much narrower, meaning more windows will be glass, “says Camm.
The development of heat technology means that aluminium windows and doors are the best on the market for insulating against heat penetration. Unlike PVC or wood, which can expand and contract when temperatures change, aluminium is very stable. There is no expansion or contraction that would make it difficult to open or close a door. Aluminium has a large glass surface that insulates, while glass is an excellent insulator, so PVC rods constructed with steel are needed to reduce heat dissipation, “explains Camm.

Aluminium doors and windows are very durable, never rotate, do not rust and unlike wood you do not need painting or staining to stay weatherproof. Aluminium windows and doors last for decades , making them ideal for use in homes, office buildings, offices and other buildings.

Older houses often have steel windows and door frames, but aluminum doors and windows last much longer and longer than steel doors.
Even better is that aluminium frames are usually cheaper than wood, which saves you money in the beginning and in the long run. Aluminium windows are a great way to get the look you want while offering all the benefits of modern windows. The above is true for most aluminium windows and doors today, but when it comes to heat loss, the material holds just as well, even if you like it for aesthetic reasons.
Of course Everest could boast its speed of installation, but it is the details that really make it stand out. Six weeks after the purchase we installed our bespoke windows and doors, and the difference with Everest is that they are much more durable than most aluminium windows or doors.
The aluminium profile is insulated with a specially developed polyamide core to prevent heat transfer to the frame. The internal low-E glass reflects the heat back into the room and thus minimises energy loss. TPE gasket improves weather resistance, as it has no accumulators and therefore always returns to its natural position. Together with the argon-filled glass cracks and the high temperature of the material, this minimizes heat loss and keeps more noise away.

The corrosion-resistant frame of Everest exceeds British weather and performance standards, and the low iron panes improve the clarity of the windows. The high-quality, high-performance aluminium window frame also exceeds British window standards.

Aluminium is 100 percent recyclable and protects the environment without losing quality. Everest is also unique in that it uses aluminium cladding around the window edges to give the product a white finish. The company is the foundation for all Everest products such as windows, doors and sealing units as well as all other building components. Everest is the world’s largest manufacturer of aluminium window and door panels, in addition to its high-performance aluminium frame, which means that its windows use less sealants and fillers than a frame.

This means that if the window eventually needs to be replaced, the frame can be melted down and converted into something new. So no matter what you decide to replace it with, it can either be recycled again and again or begged and reused.
