What is an UPVC profile?

UPVC is the abbreviated name for unplasticised polyvinyl chloride. It starts as a plastic powder, which is heated to create a liquid to inject into a mould. The mould is a long strip, ideal for manufacturing UPVC windows. Once cooled, the UPVC is cut to form the base of the frame for a double or triple-glazed window. The ‘profile’ is simply the type of UPVC window frame the UPVC is created for. Different types of windows have different UPVC profiles designed to provide structural support and solutions such as superior energy efficiency.

The different UPVC profile types

There are three main types of UPVC profiles:

  • Chamfered
  • Ovolo
  • Flush


With its neat and linear look, the Chamfered profile is a popular choice for modern homes. The clean lines and flat edges fit a contemporary aesthetic, but the unfussy finish makes them incredibly versatile. 


Rounded edges and sculptured framing make Ovolo windows the perfect profile for a traditional yet timeless look. Ideal for heritage properties, it can also enhance modern properties, lending character and elegance to contemporary country homes with its soft sightlines and curved shape.


A flush UPVC profile is seen in casement windows that fit flush against the window frame, as opposed to overlapping the frame, as in stormproof windows. It is characterised by sleek lines and has a timeless appearance. 

The profile also refers to the manufacturer/supplier. 

The top UPVC manufacturers operating in the UK are, in alphabetical order:

  • Eurocell
  • GAP Ltd
  • Halo
  • Liniar
  • Profile 22
  • Rehau

Do coloured UPVC windows matter?

Although the most popular colour of UPVC windows is still white, some customers are choosing grey, black, cream, pastel hues and even bright shades.

Coloured UPVC has the same profile as standard white but can be used to put your stamp on your home. You can opt for dual colours to match your interior and exterior architecture and decor. 

Besides colours, UPVC windows are also available in wood-grain finishes, mimicking the appearance of traditional timber windows with all the benefits of UPVC. These finishes look authentic and can even be used in period properties to blend with other homes in the area. 

Coloured and wood grain finishes cost a little (around 10-20%) more than plain white UPVC frames but can help you make a statement or remain sympathetic to the property’s surroundings.

There are other considerations when choosing coloured UPVC. For example, black UPVC can fade in direct sunlight, so it is best not to use it in areas of maximum sun exposure. 

What about window styles?

Alongside the different UPVC profiles, you also have different styles of windows. 

The main types of UPVC windows are:

  • Casement
  • Sliding sash 
  • Sliding Horizontally
  • Tilt-and-Turn
  • Bay


The most common type of window in modern UK homes, casement windows swing outwards on hinges, similar to a door. The entire window can be opened, providing excellent ventilation, while airtight seals mean they are energy-efficient and offer excellent insulation when closed. This type of window has locks embedded in the frame for your security and peace of mind.

Sliding Sash 

Sliding sash windows feature one or more panels (sashes) which slide vertically over each other to open the window. Popular in Georgian and Victorian properties, they were traditionally made of timber but have been given a modern update with UPVC. Our sliding sash windows feature multi-point locking systems and are highly secure.

Sliding Horizontally

Like sliding patio doors, sliding windows run horizontally along a track so you can control how ‘open’ you would like them to be. They use multi-point locks, so the panels cannot be lifted out to gain entry to your home. 


Tilt and turn windows are a version of casement windows, where the window swings outwards vertically but can also be partially opened by tilting it inwards at the top or bottom. They are ideal for ventilating ground-floor rooms.


Traditionally seen in period homes but also popular for modern UK homeowners, bay windows compromise three or more windows extending outwards from your home’s exterior wall. This creates a bowed or semi-circular bay in your room, increasing the living space and flooding the room with natural light.

Each style of window offers benefits and potential drawbacks, so the decision is usually made according to your budget, personal preference and your home’s aesthetic.


Given that your selection of windows can affect the overall energy efficiency, comfort and value of your home, it is important to make the right choice.

A high-quality window profile means a more effective window, but there are several excellent UPVC profiles in the UK market.
