Are uPVC Windows Better Than Plastic Windows?

Plastic windows are a typical window in older homes and bungalows. However, designs like these don’t offer you the insulation and protection that you and your home need.

Plastic, or PVC as it’s sometimes known, is a lightweight material that is durable and robust. Because of this, it has a wide variety of applications. But, in these changing times, plastic windows are beginning to become outdated.

Instead of getting these windows for your home, it could be wiser to choose uPVC windows. While uPVC has similarities with plastic, it has one key difference – it isn’t plastic.

uPVC is a polyvinyl chloride that, unlike plastic windows, doesn’t use plasticisers. As a result, frames like these are more sustainable. Not only that, but uPVC is a superb option in windows as a substitute for wood.

If you have windows that use timber in their design, you may be considering getting plastic windows to replace them. However, you might not be solving the issues. Plastic windows aren’t efficient and don’t offer as much insulation as timber windows.

Although they do have a longer lifespan in some cases, plastic can also wear down over time. As a result, you won’t be making the long-lasting investment in your home that you want and need.

uPVC windows, on the other hand, have a 30-year lifespan and an outstanding structure. Also, uPVC is fully weatherproof, coating your window in a material that keeps wind and rain well away from your home.

As a result, it can protect the internal hardware from rust, ensuring a smooth operation, and also reduce gaps for your home’s warmth to escape through. It’s fully recyclable too, ensuring you’ll make a sustainable investment.

uPVC vs Plastic Windows: Sustainability

Today, it’s crucial to invest in windows that help our climate. Right now, energy bills are on the rise as a result, as using it becomes ever more precious. Because of this, it can feel like both of these issues are on top of you.

Although you may already want to add new windows to your home to combat this, plastic windows won’t solve them. Not only is the material inefficient, but it also harms the environment.

PVC isn’t a reusable material, meaning you’ll have to throw it away after you’ve used it in your new windows. Not only that, but the lifespan of PVC isn’t as much as you think. The material is thinner and less weather-resistant than its counterparts.

Because of this, it’ll have less fight against wind, rain and other forces, meaning your window frame will wear down quicker. And, when you do decide to throw it out, it’ll go to the landfill, damaging our planet’s environment yet further.

uPVC, on the other hand, is both efficient and recyclable. Some suppliers of uPVC profiles will even use frames that have already featured in other windows before.

That way, when the time does come to replace the windows in 30 years or more’s time, you can be safe in the knowledge that it can become someone else’s window. Also, uPVC can insulate your home, meaning you can stay warm without using as much energy.

uPVC vs Plastic Windows: Efficiency

uPVC is a step up on plastic windows when it comes to energy efficiency. The material has a denser structure, meaning it’ll offer your home more insulation than PVC designs. Instead of losing heat through gaps in the design or thin materials, you’ll be able to store and capture it.

You won’t only get a uPVC frame to do this either – your new windows will feature a choice of advanced glazing that can save energy inside your home as well.

While plastic windows let a lot of heat out through their thin design, uPVC stores it inside your home. As a result, you can stay comfortable in your living space in a more natural way. You can also get slimline uPVC profiles, which don’t block any part of the glazed section.

The sleek profile allows you to flood your home with natural light and warmth, which can do the work of your central heating in controlling your home’s climate.

So, with uPVC windows, you can make your home warm without relying on your heating to do it. That means you’ll use less energy, spend less money, and enhance the feeling of your living area. Not only that, but uPVC can come in any colour or finish.

There are genuinely hundreds of ways to customise the look of the frame, so your new windows reflect your personality. No matter the colour you choose, your uPVC windows will perform as advertised.

uPVC vs Plastic Windows: Security

Plastic windows may also not be the right choice for protecting your home. The material is thin, meaning that it’s less impact resistant. Because of this, a burglar may target your plastic windows, seeing them as a straightforward target.

The windows of your home are one of the most likely places anyone trying to get in there will attempt to use as an access point. By using uPVC in the design, though, you can make that much harder for any unwanted visitors.

uPVC windows are high-security designs that use leading hardware. In your new windows, you won’t only get a durable and robust frame, but toughened glazing as well. The window will feature internal security measures across the design too, such as shootbolts, multi-point locking systems and more.

The uPVC frame will also protect and conceal most of the security features, making it a nightmare for a burglar who wants to tamper with them.

Also, uPVC windows are more rigid than plastic windows. In a uPVC frame, there are no plasticisers, which gives the plastic their flexibility. While that means it isn’t as usable in other fields, uPVC is ideally suited to windows.

Frames like these are particularly impressive when it comes to your home’s security because of their rigidity. By fitting one of these windows, you’ll improve your home and give yourself invaluable peace of mind too.

uPVC vs Plastic Windows: Durability

Plastic windows aren’t very durable options either. Over time, plastic can weaken and lose its shape in poor weather. Your plastic windows could lose performance gradually for years, and then all at once when the plastic gives out.

Something like this could happen after only 20 years, or even less in some cases. With a uPVC window, however, you can be sure of 30 years of peak performance, and even more with the right maintenance and cleaning.

uPVC is incredibly durable, and it can withstand wind and rain. The material prevents water ingress, and it can even make condensation less likely. Because of this, you’ll protect the glazing, and the rest of your home, from damage and wear.

Your frame will also be stain and scratch-resistant, meaning you won’t have to clean it very often at all. You’ll only need to wipe it down with a damp cloth every month or two to keep it appearing shiny and new.

Because of this, you can also add colours to your uPVC without worrying about them fading. No matter the colour or the finish you select for your profile, you can invest in it with confidence that it’ll retain its vibrancy and texture for years to come.

uPVC can improve the lifespan of plastic windows by at least a decade, and you may have to clean them even less. As a result, they’ll prove to be a far more worthwhile investment.
