What is UPVC?

Are you curious about what UPVC means? Before understanding upvc windows and their purpose, it is necessary to know UPVC material.

UPVC stands for Unplasticized Polyvinyl Chloride. It may sound complex, but it’s a material used to create windows that offer numerous benefits. They are often referred to as UPVC sash windows.

What Are UPVC Windows?

Now coming to our question of interest,  What are uPVC windows? They are a particular kind of window frame produced from polyvinyl chloride (PVC), which has not been plasticised and does not contain any additives that make it flexible. Due to its many benefits, UPVC is a robust and reliable material frequently used for window frames.

Why Are They So Popular?

Why is UPVC so well-liked by many people? What makes them a top choice? The secret lies in how they are really strong, help save energy and don’t need much upkeep. Here are some of the key reasons why UPVC windows are so popular:


UPVC is a durable material that resists weathering, rot, and corrosion. This longevity reduces the need for frequent replacements, making UPVC windows a cost-effective choice in the long run.

Low Maintenance

Unlike wooden windows that require regular painting, staining, and sealing to maintain their appearance and functionality, UPVC windows are low maintenance. They do not require painting or special treatments and can be easily cleaned with soap and water.

Energy Efficiency

UPVC windows have excellent insulation properties, which help reduce energy consumption and lower heating and cooling costs. The insulation properties also create a more comfortable indoor environment by minimising heat transfer.

Sound Insulation

UPVC windows provide effective sound insulation, reducing noise pollution from the outside. This feature is particularly valuable for properties located in noisy environments or urban areas.


UPVC windows are generally more affordable than windows made from materials like wood or aluminium. This makes them an attractive option for homeowners looking for high-quality windows on a budget.

Variety of Styles

UPVC windows are available in various styles, designs, and finishes. This versatility allows homeowners to choose windows that match the aesthetics of their homes, whether they have a modern or traditional design.


UPVC windows can have advanced locking systems, making them secure against potential break-ins. This feature enhances the overall safety and security of a property.

Weather Resistance

UPVC is resistant to moisture, which makes it ideal for areas with high humidity or coastal environments where traditional materials like wood might deteriorate more quickly.

Environmental Considerations

UPVC is recyclable; many manufacturers use recycled materials in their window production. This eco-friendly aspect appeals to environmentally conscious consumers.

Long-Lasting Appearance

UPVC windows retain their appearance over time, maintaining their colour and finish without fading, chipping, or peeling.

Is UPVC Plastic?

Yes, UPVC stands for unplasticised Polyvinyl Chloride, a type of plastic. It is a plastic material widely used in various applications due to its unique properties.

However, unlike regular PVC, it is unplasticised, meaning it has undergone a process that removes certain plasticising agents. UPVC is not softened through the use of plasticisers.

Instead, it is manufactured using a process that eliminates these additives to produce a rigid and durable material. This makes it less flexible than traditional PVC. UPVC is known for its exceptional resistance to weathering, corrosion, and chemical exposure.

Environmental Benefits of UPVC Windows

UPVC windows offer significant environmental advantages that contribute to a greener future. One of the prominent benefits lies in their recyclability. The UPVC material used in these windows can be recycled.

Hence, it minimises the need for new raw materials and reduces the stress on natural resources. This recycling process also helps to control carbon associated with window production. Using UPVC windows makes a positive impact as it can reduce waste and resource consumption.

The insulation properties of UPVC material effectively reduce heat transfer and enable homes to maintain stable temperatures. It reduces dependence on heating and cooling systems.

Energy consumption and greenhouse gas emissions are lowered, favouring energy conservation. The durability and longevity of UPVC windows also play a role in sustainability. Over recent years, UPVC windows have emerged as an environmentally-friendly choice.


UPVC windows have an extensive range of styles and colours available that can complement the aesthetics of any home. Whether you prefer a modern, minimalist look or a more traditional charm, UPVC windows can be customised to match your thoughts. 

Homeowners are free to express their style. In addition, compatibility with various architectural designs ensures a seamless blend of different building styles.

First, accurate measurements are taken to custom-fit the windows to the openings. Existing windows are removed, and the window frames are cleaned and prepared. The uPVC window units are then securely installed using screws and fixings. 

Proper insulation and sealing materials are applied to prevent drafts and moisture infiltration. Skilled workers can efficiently fit these windows into your home in a short period.Contact us for expert installation services tailored to your needs.

Security Features

UPVC windows are designed with modern security needs in mind. They incorporate advanced locking mechanisms that enhance the overall safety of your home.

Impact-resistant glass options offer enhanced protection against unauthorised entry and break-ins. Their sturdy construction and modern locking mechanisms give a heightened sense of security.

Noise Insulation

The UPVC material is a natural insulator and effectively reduces outdoor noise infiltration. It provides a quieter and more serene living environment inside your home.

Combining insulated frames and double or triple glazing creates a barrier, significantly reducing external noise penetration. This feature particularly benefits homes in noisy urban areas or near busy streets.

UPVC vs. Wood Windows

The comparison between UPVC and wood windows reveals distinct advantages of each. UPVC windows are created from durable, Unplasticised Polyvinyl Chloride, which offers longevity and resistance to environmental elements. In contrast, wood windows exude a classic and timeless charm, adding warmth to a home’s interior.
