Introduction
Quick answer: A tilt and turn window is a window with one handle and two ways to open. In the tilt position the top of the sash leans inwards for secure ventilation; in the turn position the whole sash swings inwards like a door, for cleaning or full airflow.
Tilt and turn windows are growing in popularity due to their versatility and energy efficiency. Whether you’re renovating your home, upgrading, or considering tilt and turn double glazed windows for improved insulation, this guide will cover everything you need to know.
In this blog, we’ll explain how these windows work, whether they’re more expensive than traditional window styles, their security features, and how to adjust IdealCombi turn and tilt windows.
What is a Tilt and Turn Window?
A tilt and turn window is a dual-function window system that opens in two ways:
- Tilting Mode: The top of the window tilts inward, allowing for secure ventilation while keeping the lower part of the window closed.
- Turning Mode: The window swings open like a casement window, providing full access for cleaning or fresh air.
Unlike a standard casement window, which is hinged at the side and usually opens outwards, a tilt and turn window opens inwards in both modes. That is why it can tilt open safely for ventilation, and why you can clean the outside glass from inside the room.
They are a popular choice in modern homes, apartments, and commercial buildings due to their aesthetic appeal, ease of maintenance, and energy efficiency. They are commonly found in Europe but are becoming more common in the UK and North America due to their practical benefits, superior insulation and energy efficiency.

Types of Tilt and Turn Windows
Tilt and turn windows come in different materials and glazing options, each offering unique advantages:
- Aluminium Tilt and Turn Windows – Sleek, modern, and incredibly durable. Ideal for contemporary homes and large window openings.
- uPVC – Affordable and energy efficient. Great for residential homes.
- Double Glazed Windows – Provide superior insulation, helping to reduce energy costs and improve soundproofing.
How Do Tilt and Turn Windows Work?
A tilt and turn window works by using one handle to move a locking bar between three positions: closed, tilt and turn. Each position releases a different set of hinges, so the same sash can either tilt inwards at the top or swing open from the side.
Turn and tilt function by using a single handle that controls both opening mechanisms:
- Turn the handle 90 degrees: The window tilts inward from the top, allowing for safe ventilation.
- Turn the handle 180 degrees: The window swings open fully, like a door, for maximum airflow and easy cleaning.
Inside the edge of the sash, the handle drives a bar that moves several locking points around the frame. In the tilt position the side locks release and the sash pivots on its two bottom corner hinges, held at the top by a stay. In the turn position the bottom hinges release and the sash swings on its side hinges. A built-in safety catch stops the handle being moved to a position that would let the sash come away from the frame.
This unique design provides superior ventilation, security, and ease of maintenance, making it a preferred choice for modern homes and offices.
Can Tilt and Turn Windows Open Outwards?
No, turn and tilt windows only open inward. The inward-opening mechanism is essential for the tilt function to work properly.
If you require outward-opening windows, consider:
- Casement Windows – These are similar in appearance but open outward.
- French Windows – Ideal for larger openings with a classic look.
- Sliding Windows – A space-saving alternative.
They are ideal for high rise buildings or small balconies, as they don’t interfere with external spaces.
How to Open IdealCombi Tilt and Turn Windows
To open a tilt and turn window:
- Check the handle is in the closed position.
- For ventilation, move the handle to the tilt position. The top of the sash leans inwards and the bottom stays locked.
- To open fully, return the handle to closed, then move it to the turn position. The whole sash swings inwards on its side hinges.
- To close, push the sash back against the frame, then return the handle to the closed position.
On Idealcombi Futura+i windows the tilt position opens the top of the sash by about 100 to 150 mm, giving a free ventilation gap of about 20 mm, depending on the sash size.
Opening a tilt and turn window is simple:
- For Ventilation Mode: Turn the handle 90 degrees so the window tilts inward at the top.
- For Full Opening Mode: Turn the handle 180 degrees so the window swings inward.
- To Close the Window: Return the handle to the original position and push the window shut.
Advantages and Disadvantages of TIlt and Turn Windows
Advantages
1. Versatile Opening Mechanism
- The tilt mode allows for controlled ventilation without fully opening the window.
- The turn mode provides a full opening for easy access and maximum airflow.
2. Superior Security
- Multi-point locking system makes them harder to break into.
- Tilt function allows for ventilation while keeping the bottom of the window securely closed.
- Toughened or laminated glass offers extra protection.
3. Energy Efficiency
- Tilt and turn double glazed windows provide excellent insulation, reducing energy loss.
- Keeps your home warmer in winter and cooler in summer, lowering heating and cooling costs.
4. Easy Maintenance
- Since the window opens inward, it can be cleaned from inside the home—ideal for high-rise apartments.
- No need to reach outside or hire professional window cleaners for upper floors.
5. Modern Aesthetic
- Sleek and contemporary design, especially aluminium tilt and turn windows, which offer a minimalist, high-end look.
- Available in various frame materials, including uPVC, timber, and aluminum.
6. Improved Sound Insulation
- Tilt and turn double glazed windows reduce external noise, making them ideal for busy city environments.
7. Child Safety and Pet-Friendly Design
- The tilt function allows fresh air in without creating an opening large enough for children or pets to climb through.
Disadvantages
1. Higher Cost
- More expensive than traditional casement or sliding windows due to the advanced dual-function mechanism.
- Aluminium tilt and turn windows cost more than uPVC but offer better durability.
2. Heavier and Bulkier
- The sturdy construction makes them heavier than standard windows, requiring strong wall support.
- Larger turn and tilt windows may need reinforced hinges to support the weight.
3. Cannot Open Outwards
- Unlike casement or sliding windows, turn and tilt windows only open inward, which may not suit every home’s layout.
Will a tilt and turn window suit your room?
Check the space inside the window before you choose. Because the sash opens inwards in turn mode, it needs clear room to swing.
- Curtains and blinds: fit them so they clear the sash, or choose blinds fixed to the sash or integrated in the glass.
- Window sills: items on the sill can stay when the window is tilted, but must be moved before you turn it open.
- Furniture and radiators: keep the swing area clear, especially for large sashes.
- Outside: because nothing opens outwards, you can fit external shutters, flyscreens or a Juliet balustrade.
If the room cannot give the sash space to swing, an outward-opening window may suit it better. See inward or outward opening windows.
Why are they more expensive?
Yes, usually. Tilt and turn windows typically cost more than a casement window of the same size and specification, because of the extra hardware, the multi-point locking and the tighter manufacturing tolerances they need. To compare fairly, price a casement and a tilt and turn window with the same frame, glazing and security rating.
| What affects the price | Why it matters |
|---|---|
| Frame material | uPVC is cheapest, then aluminium; timber and alu-clad timber cost the most |
| Size | Larger sashes need heavier hardware and glass |
| Glazing | Triple glazing, laminated or acoustic glass add cost |
| Security | Higher-rated locks and PAS 24 certification add cost |
| Installation | Fitting is usually priced per window on top of supply |
See Idealcombi window prices for typical costs by window type.
They are typically more expensive than traditional window styles, such as casement or sash windows. This is due to several factors:
- Advanced Mechanism: The dual opening functionality requires high quality hardware and precision engineering.
- Innovative Security Features: The multi-point locking system adds to the cost.
- Energy Efficiency: High performance tilt and turn double glazed windows provide better insulation, reducing energy bills in the long term.
- Customisation Options: Aluminium tilt and turn windows, for example, can be customised with different frame colours and finishes, increasing the price.
The extra cost is partly offset by everyday benefits: you can clean the outside glass from inside, and the tilt position gives secure ventilation, so a window can stay open when you are out.
How secure are these windows?
Security is a top priority for homeowners, and turn and tilt windows offer great security features available. Here’s some:
- Multi-Point Locking System – Features multiple locking points, ensuring security even when in tilt mode for ventilation.
- Reinforced Frames – High quality aluminium tilt and turn windows offer additional strength and resistance to break ins.
- Toughened or Laminated Glass – Tilt and turn double glazed windows come with reinforced glass, increasing security and impact resistance thus making it harder to break in.
If security is a priority, turn and tilt windows can be a much safer option than traditional casement or sliding windows.
How to adjust IdealCombi Tilt and Turn Windows
Adjusting your Idealcombi tilt and turn windows ensures they operate smoothly and maintain optimal performance. Here’s how to make common adjustments:
1. Height Adjustment: To raise or lower the window sash:
- Locate the height adjustment screw on the bottom hinge.
- Use an Allen key to turn the screw:
- Clockwise to raise the sash.
- Counterclockwise to lower the sash. This ensures the sash aligns correctly within the frame.
2. Lateral Adjustment (Side Alignment): If the sash is misaligned horizontally:
- Find the lateral adjustment screws on both the top scissor hinge and the bottom hinge.
- Adjust these screws to move the sash left or right, ensuring it sits evenly within the frame.
3. Adjusting Closing Pressure: To modify the pressure between the sash and the frame:
- Identify the mushroom bolts (locking pins) along the sash.
- Rotate these bolts:
- Clockwise to increase pressure (tightening the seal).
- Counterclockwise to decrease pressure. Proper adjustment ensures a firm seal, enhancing insulation and security.
4. Handle Operated Brake Adjustment: If your window features a handle-operated brake to hold the sash in position when opened:
- Open the window to the desired position (between 19° and 89°).
- Turn the handle downward to activate the brake, securing the sash in place.
- To release, slightly open the sash further, then return the handle to its original position. This mechanism allows the window to stay open at various angles for controlled ventilation.
5. Resetting the Espagnolette (Locking Mechanism): If the locking mechanism becomes misaligned:
- Position the handle horizontally.
- Gently push the sash into the frame.
- Turn the handle upward to the vertical position.
- Close the window by turning the handle downward to the locked position. This sequence resets the espagnolette to its default state.
Important Considerations:
- Always perform adjustments with the window closed to ensure safety and accuracy.
- Use appropriate tools, typically an Allen key, for these adjustments.
- Regularly inspect and maintain your windows to prolong their lifespan and functionality.

Tilt and turn window FAQs
Do tilt and turn windows open outwards?
No. Both the tilt and turn modes open inwards; the tilt function depends on it. If you need an outward-opening window, choose a side hung or top hung window instead.
Are tilt and turn windows safe for children?
The tilt position opens only a small gap at the top, so it is a safer way to ventilate than a fully open sash. For extra control, fit a lockable handle or a restrictor. See handles and restrictors.
Can a tilt and turn window be a fire escape window?
Yes, if it is large enough. In turn mode the sash opens fully, so a correctly sized window can meet escape requirements. See fire egress windows.
Are tilt and turn windows good for flats and high-rise buildings?
Yes. You can clean the outside glass from inside, and the tilt position ventilates without a wide opening. See specifying windows for high-rise buildings.
How much do tilt and turn windows cost?
Usually more than an equivalent casement. See the cost section above and Idealcombi window prices.
