Windows Open Inwards vs. Windows Open Outwards

The direction in which your windows open can significantly impact your living space. Inward-opening windows swing inside your home when you operate them. This design choice has its merits. For instance, inward-opening windows are a popular choice in areas where external space is limited, like crowded urban neighbourhoods. They don’t encroach on outdoor areas, making them ideal for balconies and terraces.

On the flip side, outward-opening windows can provide better ventilation. By opening outwards, they create a funnel-like effect, drawing fresh air into your home. This design is particularly advantageous in areas with pleasant weather, where the goal is to maximize natural ventilation.

Inward Opening Windows – Pros

Inward-opening windows offer several advantages. First and foremost, they are space-savers. In tight living quarters, every inch matters. Inward-opening windows provide an elegant solution by utilizing the existing interior space efficiently.

Additionally, inward-opening windows are easier to clean from the inside. This convenience is especially appreciated in high-rise buildings or homes where accessing the exterior for cleaning purposes can be challenging.

Inward Opening Windows – Cons

However, inward-opening windows do have their downsides. One of the significant disadvantages is limited ventilation. While they are excellent space-savers, they don’t provide the same level of airflow as outward-opening windows.

Another drawback is the potential obstruction of curtains and blinds. When these windows swing inside, they can interfere with window treatments, limiting your interior design options.

Outward Opening Windows – Pros

Outward-opening windows, as mentioned earlier, excel in ventilation. By opening outwards, they capture the natural flow of air more effectively. This can be a game-changer in areas where cooling breezes are abundant, as it helps maintain a comfortable indoor environment without relying heavily on artificial cooling systems.

Moreover, outward-opening windows often come with more robust locking mechanisms, enhancing security. The outward swing also prevents intruders from easily tampering with the windows from the outside.

Outward Opening Windows – Cons

The primary disadvantage of outward-opening windows is their space utilization. In outdoor-limited areas, they might not be the best choice as they encroach on your external space, making balconies and terraces feel smaller.

Additionally, cleaning the exterior of these windows can be a hassle, especially for multi-story buildings. Regular maintenance might require professional help, adding to the overall cost.

Which Type of Window Looks the Best?

The aesthetic aspect of windows is subjective and largely depends on your personal preferences and the architectural style of your home. Some people prefer the sleek, modern look of inward-opening windows, while others appreciate the classic appeal of outward-opening windows. Consider your home’s design and your own sense of style when making this decision.

Inwards vs. Casement: Decoding the Better Window Dynamics

Comparing inward-opening windows with casement windows involves considering various factors such as energy efficiency, security, and maintenance. Casement windows, which are hinged at the side and typically open outward, offer excellent ventilation and security. They provide a tight seal when closed, minimizing drafts and enhancing energy efficiency.

Inward-opening windows, including tilt-turn windows, are versatile in their operation. They can open inward like a casement window or tilt at the top for secure ventilation. This dual functionality makes them popular in many European countries.

When deciding between inward-opening windows and casement windows, evaluate your priorities. If space-saving and easy cleaning are essential, inward-opening windows might be the better choice. However, if you prioritize maximum ventilation and a tight seal, casement windows could be the way to go.

Key Features of Inward Opening Windows (and Tilt Turn Windows)

When choosing inward-opening windows, several key features demand your attention:

  1. Hardware: High-quality handles, hinges, and other hardware components are crucial for smooth operation and longevity.
  2. Colour: Consider window frames that complement your home’s exterior and interior colour scheme.
  3. Glass: Choose glass options that provide the desired level of insulation, UV protection, and privacy.
  4. Frame Type: Different materials like uPVC, aluminium, and wood offer varying levels of durability and energy efficiency.
  5. Locks: Invest in robust locking mechanisms to enhance security and peace of mind.
  6. Price: Compare quotes from different manufacturers and suppliers to find a balance between quality and affordability.
  7. Quality: Opt for reputable brands known for producing high-quality, durable windows.
  8. Soundproofing: If you live in a noisy area, prioritize windows with excellent soundproofing capabilities for a quieter indoor environment.


What are the benefits of inward-opening windows?

Inward opening windows provide better protection against wind and rain, as they close into the frame, creating a tighter seal. They are also easier to clean from the inside, enhancing convenience. Additionally, they offer enhanced security, as the hinges are typically hidden, making them harder to tamper with.

What are inward-opening windows called?

Inward-opening windows are commonly known as “casement windows.” Casement windows are hinged at the side and can swing either inward or outward. They are popular for their practicality and versatility in various architectural designs.

Can you put shutters on windows that open inwards?

Yes, shutters can be installed on inward-opening windows. However, the design and installation need to be carefully planned to ensure they do not obstruct the window’s movement. Specialized shutters, such as interior plantation shutters or European-style shutters, are often used, designed to complement the inward opening mechanism.

Final Thoughts

In conclusion, choosing between inward-opening and outward-opening windows boils down to your specific requirements and preferences. Consider the space available, desired ventilation, cleaning convenience, and overall aesthetic appeal. Don’t forget to focus on the quality of materials and hardware to ensure your investment lasts for years.

My technician Andrew replaced all my sash windows that had rotten sills. Accessing the rotten sills was not an easy task. He explained to me what needed to be done in order to fix the problem. He is a great person and I’m happy that he was the one who did the job. He is reliable, tidy, friendly and very professional. I highly recommend him.



I hired Andrew and Alex a while back to repair my damaged sash windows. They were was very considerate and very patient as he did his job. A few days ago, I had another problem with one of my sash lock keys and I called him again to come and fix the problem. I’m very impressed that Liam responded quickly and he not only fixed the problem but he also gave me a spare key. What a great after sales service!

I’m very impressed with the new windows that Andrew installed and also the reconditioning job that he did on other sash windows. The quality of his work is by far more superior than what we got when we hired another company a few years back. We will certainly hire him again if any window work arises

Alex did a great job in fixing windows in our terraced house. The windows were broken, frames damaged and the wood was also rotten. Alex's job was high quality and he did it pretty fast. I was also very impressed that he was considerate of my son’s asthma condition and maintained cleanliness. Top work.



Andrew just recently replaced three sash windows in my Edwardian house. He also repaired and replaced some sills and draught proofed three windows. In addition to that, he also did some carpentry work. What I like the most about Liam is that he did a clean job. He is very professional and always updated me about the timescales and costs. He also did his job with minimal disruptions. I highly recommend him.
