A Practical Guide to Top Hung Windows, Side Hung Windows, and Tilt & Turn Windows
In South Africa, our homes need to do more than just look good; they need to breathe, withstand the elements, and offer comfort year-round. That’s where aluminium windows shine. Known for their durability and sleek aesthetics, aluminium windows are the go-to for coastal properties, modern builds, and energy-efficient projects alike.
But which window type suits your space best? Here’s a straightforward guide to the three most popular aluminium window types available from Fenster, and why architects and homeowners across the country trust them.
3 Most Popular Aluminium Window Types
1. Top Hung Windows
What they are:
Top hung windows are hung from friction stays at the top and open outward from the bottom
Where they work best:
- Bathrooms and guest toilets
- High wall placements (e.g., above doors or in stairwells)
- Rainy or coastal regions where airflow is needed without letting water in
Why they’re a smart choice:
– Rain-resistant ventilation. It can stay open even during light showers
– Great for natural airflow without compromising on wall space
– Minimal visual clutter with slim frames and discreet operation
Things to keep in mind:
- Fenster can make top-hung windows as large as 2000mm x 1500mm to give you a ventilated, uninterrupted view.
Top hung windows are perfect for a room’s primary source of permanent ventilation, without opening a door.
2. Tilt and Turn Windows
What they are:
A dual-function design: tilt the window inwards from the top for ventilation, or swing it in from the side for full opening. Always note that these windows open inward into your house.
Best suited for:
- Multi-storey homes
- Apartments and townhouses
- Schools or nurseries (for safe ventilation)
Why architects love them:
– Versatile, which is perfect for controlled airflow or emergency egress
– Easy to clean from indoors (especially useful on upper levels)
– Modern European aesthetic and great security
Keep in mind:
- More advanced hardware means a higher upfront cost
- Requires precision installation for smooth operation
3. Side Hung Windows
What they are:
Also known as casement windows, these are hinged on one side and open inward or outward, similar to a door.
Where they work best:
- Kitchens, studies, and bedrooms
- Anywhere you want more control over ventilation
- Properties with space for outward opening
Why they’re a favourite:
– Excellent seal for energy efficiency and draught control
– Allows for full top-to-bottom airflow
– Clean sightlines with large single-glass panels
Considerations:
- Requires external space to open outward
- It can not be kept open during rainy days and light showers
Why Fenster Aluminium Windows Stand Out
At Fenster, we don’t believe in cutting corners. Every aluminium window we design is purpose-built for South African conditions, whether it’s the baking Gauteng sun, Durban’s humidity, or the Cape’s salty sea breeze.
What sets us apart:
- German-engineered systems for long-term performance
- Premium corrosion-tested hardware suitable for coastal applications
- EPDM and silicone seals for maximum airtightness and thermal efficiency
- Custom configurations for specific climate zones and architectural styles
You can see the attention to detail in every unit we craft. From sturdy friction stays in our side-hung designs to secure locking mechanisms in tilt-and-turn windows, Fenster quality isn’t added on; it’s built in.
Matching the Right Window to Your Project
Whether you’re building a seaside getaway or upgrading a modern suburban home, here’s a quick guide:
Window Type | Best For | Key Benefit |
Top Hung | Bathrooms, hallways, and above doors | Ventilation during rain |
Tilt & Turn | Double-story homes, schools, and apartments | Easy cleaning + dual-function ventilation |
Side Hung | Bedrooms, kitchens, and small to medium rooms | Strong seal + wide airflow |
Final Thoughts
Choosing the right window style can elevate a home from functional to exceptional. Aluminium delivers strength, elegance, and low maintenance, but it’s the right configuration that unlocks true performance.
