What Type of Material is uPVC?

uPVC is the material that the frame of the double glazed windows is made off. This material is based on plastic powder (unplasticized polyvinyl chloride, uPVC), which is heated up and injected through a mold in order to form its shape. After it has cooled through different methods, the uPVC is cut and prepared to be assembled in a double glazed window together with the other components.

uPVC is not the only material that double glazed window frames are made of. They can also be made of timber and aluminium. All three materials come with different advantages and disadvantages, but overall, uPVC is the most used. Furthermore, double glazed windows can be produced in many different shapes with variety of mechanisms (tilt and turn windows for instance). 

How do uPVC Double Glazed Windows Work?

What makes the uPVC double glazed windows so functional is the space between the two panes of glass that allow the air to be trapped, which creates the following benefits:

1. This air acts as insolation, thus it does not allow for cold or hot air to easily pass between the inside and outside of the house.
2. It also prevents condensation from forming inside the house when it's cold outside and warm inside.
3. Furthermore, uPVC windows reduce noise pollution by minimizing the amount of outside noise that can pass through the glass.

Choose uPVC Windows and Increase the Value of Your Home

Did you know that owning a house with uPVC windows can increase the value of it? Not only that, but uPVC windows can help with noise reduction, energy saving, and much more.

To clearly outline the advantages and disadvantages of uPVC windows, we have listed them below.

Advantages

 1. Low Cost. 

Compared to the other materials that double glazed window frames can be made from, uPVC windows are the cheapest option. Although, this is not even the best part of uPVC windows, it is still an important factor if you are worried about their cost effectiveness.

2. Low Maintenance.

Another hugely attractive advantage of uPVC windows is that they require remarkably low maintenance. Other frame materials like timber and wood need to be repainted every 5 years, alongside some refilling and patching because they tend to rot and flake. This is not the case with uPVC window frames. They never flake, rot, rust or fade. All they need is the occasional cloth wipe.

3. Insulation.

Insulation is another strong feature of uPVC windows. These windows were created to provide the most optimal heat and energy insulation. Being able to keep the sound and heat out of the house so effectively, is largely responsible for uPVC windows’ popularity.

4. Water Proof.

The biggest problem that wood window frames have is the propensity to swell when the weather is damp. This can become dangerous because the glass can loosen up, and furthermore, it can become easier for an intruder to enter your home. Alternatively, uPVC frames are storm and weather proof, since the damp cannot enter through the surface of uPVC windows frames. Hence, they are non-corrosive and will not be eroded by bad weather.

5. Durability.

From all the frame materials available for double glazed windows, uPVC is the most durable. Aluminium can pick up rust over time, and wood can rot and warp. uPVC, however, is resilient and though. Thus, you will not have to replace them for a very long time. Some companies even offer a guarantee of 10 years.

6. Security.

uPVC is reliable and trustworthy when it comes to security, as well. The way the frame is constructed, it is difficult to break through or be damaged.

7. Style.

Double glazed window companies are producing all types of windows to suit any home. You can have uPVC windows in a range of colours, styles, and sizes. There was a time when uPVC were only produced in white colour, but there have been many developments in recents years that lead to a wider variety being offered. You can choose from turn and tilt frames, casement, french windows, and even sash windows. Nevertheless, it is important to remember that the more openings a windows has, the greater the cost.

Disadvantages

1. Aesthetics.

Even though uPVC windows come in many styles and colours, in some people’s eye, their simple plastic look is far from attractive, and it looks unstylish compared to aluminium or timber. Thus, if aesthetics of uPVC windows is something very valuable to you, uPVC windows might not be the best solution.

Check the Energy Ratings of Your Windows to Find Out How Efficient They Are

One of the main benefits of uPVC double glazed windows is that they will save you energy, since the windows will not allow the heat of your home to escape easily. To help the users understand how much energy efficient their double glazed windows will be, in 2004, Windows Energy Ratings were launched by the British Fenestration Rating Council (BFRC).

If you take in consideration that 30% of the heat within your home escapes from the windows, you need to make sure that you choose uPVC windows that have high energy efficiency rating.

All You Need to Know About Windows Energy Rating

The Windows Energy Rating (WER) will tell you how energy-efficient your windows are. The most efficient windows are those with A+ rating, and the least efficient with G rating. Hence, the rating system is based on a scale from G to A+. This system is similar to the rating systems of the other household appliances, light bulbs and white goods.

The picture below show the typical windows rating labels in the UK which are supported by registered bodies.

You are probably wondering what exactly these ratings tell you about your double glazed windows.

A window’s rating is defined by a formula that takes into account the total solar heat transmittance, amount of sun’s heat that can pass through the glass (g-value), the U-value of the whole window (both frame and glass), the air infiltration through the window seals and lastly, how good the windows are at keeping the heat in your home. Thus, the rating sums up the overall performance of the window with all its components and how effectively they work together.
