Choosing new windows is one of the most impactful home improvement decisions you can make. The right uPVC window style can transform the look of your property, improve energy efficiency, reduce noise and make everyday life more comfortable. The wrong choice can leave you with draughts, poor ventilation or a design that simply does not suit your home.
This guide walks you through the most popular uPVC window styles, what makes each one different, and how to decide which is right for your property.
What are uPVC windows?
uPVC stands for unplasticized polyvinyl chloride. It is a rigid, durable plastic that has been used in window frames across the UK since the 1980s. Unlike older materials, uPVC frames do not rot, warp or require repainting. They offer excellent insulation, strong security features and are available in a wide variety of colours and finishes.
The numerous benefits of uPVC windows explain why they remain the most popular choice for UK homeowners. They deliver excellent value, low maintenance and strong energy efficiency, all at a competitive price.
At Malbern Windows, we have been supplying and fitting uPVC windows across Manchester and the North West since 1983. Our range of styles covers everything from traditional sash designs to contemporary tilt and turn systems, all manufactured in the UK and installed by our own experienced team.

The most popular uPVC window styles explained
Understanding the different types of uPVC windows is the first step to finding the right fit for your home.
Casement windows: the UK’s most popular choice
uPVC casement windows are hinged at the side and open outward. They are the most widely fitted window style in the UK and with good reason.
Casement uPVC windows offer:
- A larger glazed area for maximum natural light
- Excellent ventilation when fully opened
- Multi-point locking for strong security features
- A clean, versatile look that suits modern homes and traditional properties alike
Whether you are replacing a single window or upgrading your entire house, uPVC casement windows are an excellent choice. They are available in a variety of colours and finishes, including woodgrain effects that bring a touch of elegance to period properties.
A flush casement window takes this design further. The sash sits completely level with the outer frame, giving the appearance of traditional timber joinery. Flush casements are an ideal choice for conservation areas or homes where traditional charm matters.
Sliding sash windows: classic style with modern performance
The sash window is one of Britain’s most enduring window designs. Originally crafted in timber for Georgian and Victorian homes, modern uPVC sash windows replicate the same elegant proportions with none of the maintenance headaches.
uPVC sash windows slide vertically, with the top and bottom sashes moving independently. This gives you precise control over ventilation and keeps the traditional look intact.
They offer:
- Authentic styling that complements period properties
- Excellent energy efficiency with double glazing as standard
- Triple glazing available for superior sound insulation and heat loss reduction
- Made-to-measure sizing for a perfect fit in original apertures
If your home has traditional windows and you want to preserve its architectural style, uPVC sash windows are an excellent choice.

Tilt and turn windows: smart design for practical living
Tilt and turn windows are a popular choice for upper floors and rooms where easy cleaning and plenty of ventilation are priorities.
A single handle controls two different opening modes:
- Tilt the top of the sash inward for controlled, safe ventilation
- Turn the sash fully inward for maximum airflow and easy access to the outer glass
This makes them ideal for flats, modern homes and any room where ladder-free cleaning is important. Their tight seal and multi-chambered uPVC frames deliver excellent insulation and contribute directly to lower energy bills.
Bay and bow windows: light, space and panoramic views
Bay and bow windows project outward from the wall, increasing natural light and creating panoramic views from inside the room.
- Bay windows use angled flat glass panels to create a structured projection
- Bow windows use a curved arrangement of glass panels for a softer, more rounded look
Both styles add aesthetic appeal and a touch of class to any property. They work well in living rooms and dining rooms where the feeling of space is important. Each installation is made to measure, so every window is a perfect fit for your home.

Fixed and arched windows: character and unobstructed views
Fixed windows do not open. They are used where light and unobstructed views matter more than ventilation, often alongside opening windows as combination windows.
Arch windows add architectural character and work particularly well on period properties or contemporary extensions where a statement window design is needed. At Malbern, our arched uPVC window frames are made to your exact radius and aperture, so the fit is precise and the finish is clean.
How to choose the right uPVC window style
Not sure which window style is right for your home? Work through these key factors.
1. Think about your property type
- Period properties and traditional homes: sliding sash, flush casement or arched windows suit older architectural styles
- Modern homes and new builds: casement, tilt and turn or bay windows complement contemporary design
- Conservation areas: flush casement and sash styles are most likely to meet planning requirements
2. Consider how each room is used
- Bedrooms: tilt and turn windows offer safe overnight ventilation
- Kitchens: casement windows provide excellent ventilation and easy opening
- Living rooms: bay or bow windows maximise light and space
- Bathrooms: tilt and turn or casement styles work well with obscure glazing options
3. Choose your glazing
All our uPVC windows are available with double glazing as standard. Triple glazing is available for improved sound insulation and even lower energy bills. Both options include argon-filled sealed units and low-e glass to minimise heat loss.
4. Pick your colour and finish
uPVC frames are available in a range of colours, from classic white and cream to anthracite grey, black and Chartwell Green. Woodgrain foil finishes add traditional charm without the upkeep of real timber. The right colour choice can transform the aesthetic appeal of your home.
5. Think about the window frame material
uPVC remains the most popular frame material for UK homeowners because of its combination of performance, low maintenance and excellent value. If you are considering aluminium casement windows for a more contemporary look, our team can talk you through the differences and help you decide.

Why the benefits of uPVC windows still stand up in 2026
As of June 2026, uPVC windows remain the dominant choice for UK home improvement projects. The reasons are straightforward:
- Lower energy bills: A-rated double glazing reduces heat loss significantly compared to older single-glazed units
- Low maintenance: no painting, no treating, just an occasional wipe-down
- Security: multi-point locking systems across all styles
- Durability: uPVC window frames last 20 to 30 years or more
- Choice: a wide variety of styles, colours and glazing options to suit any home
- Structural integrity: reinforced frames that hold their shape for decades
