If you are considering refurbishing your property with new windows, you might be pondering which material would best suit your home.

uPVC, or unplasticised polyvinyl chloride, is a cost-effective and durable building material. It boasts a long life span, low maintenance and when engineered to a high standard, harbours excellent energy efficiency ratings. As far as other materials go, there is no other that offers such high levels of energy efficiency, security and durability for such an affordable cost. As a result, uPVC is a fantastic material for use in new windows and doors. Engineered with longevity, security and resilience in mind, uPVC windows have become increasingly popular in recent years. They are popular for installation within traditional and contemporary properties alike.

So what are uPVC windows? And what are the benefits of installing them in your home?

What are uPVC windows?

As the name suggests, uPVC windows are any number of window styles engineered in durable unplasticised polyvinyl chloride. When manufactured to a high standard, uPVC windows are incredibly resilient. They are durable in the face of adverse weather and will not peel, crack, fade, warp or rot.

The benefits

If you are considering refurbishing your property, you might be wondering which material would best suit your home. uPVC has steadily grown in popularity over the years. It offers a multitude of benefits for the modern homeowner.

Energy efficiency

If you have a more traditional home or even just older style windows, you may be concerned about losing the character and other historical elements they bring to your home. The reality is, older style windows often offer no additional insulation against the effects of adverse weather. Failing to refurbish your old windows can bring a myriad of issues into your interior living spaces. Issues include damp, condensation, mould and even rot. Poor insulation can wreak untold damage on the structural integrity of your home, as well as the health of your family.

uPVC combines traditional aesthetics with modern conveniences and as a result, are an excellent replacement for older style windows. As a standard, most manufacturers engineer their windows with innovative thermal break technology, internal beading and modern glazing. This means that when engineered to a high standard, uPVC windows boast exceptional energy efficiency and thermal retention ratings.


uPVC boasts a combination of longevity and very little required maintenance. It is also one of the most cost-effective options on the market. They can also save you the hassle of costly utility bills by properly insulating your home with proven thermal efficiency.

Variety of colour choices and styles

Contrary to popular belief, your new uPVC windows don’t have to be white. There have been great advancements in the window industry in recent years. This means uPVC can be engineered in a variety of colours and different styles.

For a bold look, you might opt for Chartwell Green or even Anthracite Grey. At the end of the day, the colour you choose will come down to your unique tastes. It will also depend on the exact specifications of your property.

The wide variety of colours and styles isn’t the only reason uPVC is so popular. Modern uPVC windows also benefit from heightened security and provide exceptional insulation from noise pollution among other conveniences.

Noise insulation

Modern uPVC windows are engineered with multi-chambered insulating profiles and argon gas sealed units. As well as providing an excellent barrier from the effects of adverse weather, uPVC windows also insulate your property from noise pollution. This is especially useful for homeowners living in high-density areas with busy roads.

For an extra layer of protection, you might also want to consider adding acoustic glass.

Low maintenance

Unlike older style windows, uPVC does not need repainting or regular maintenance. In fact, all uPVC windows really need is the occasional wipe down with warm soapy water to keep them looking brand new and fresh.


Modern uPVC windows should be engineered with security in mind. It’s important to look for reputable window companies such as Majestic Designs, who manufacturer their products with multi-point locking mechanisms as a standard. It’s also important to look out for other security features such as internal beading and durable double glazing.


uPVC is a very environmentally friendly material and is 100% recyclable, meaning when it’s time to retire your windows, manufacturers will be able to melt down the frames and recycle them into a number of other products used in construction such as gutters, pipes and bins.
