Inward opening windows, also known as tilt and turn windows or inswing windows, are designed to open towards the interior of a building. These types of windows offer several benefits and can be an excellent choice for various types of buildings. Here are some key points to consider:
Benefits of Inward Opening Windows
- Ease of Cleaning:
- Since the windows open inward, both the inside and outside surfaces can be easily cleaned from within the building. This is especially beneficial for high-rise buildings where exterior cleaning can be challenging and expensive.
- Ventilation Control:
- Many inward opening windows, particularly tilt and turn windows, offer versatile ventilation options. The tilt function allows the top of the window to tilt inward, providing gentle ventilation while maintaining security and privacy. The turn function allows the window to open fully inward, offering maximum ventilation.
- Security:
- Inward opening windows can be designed with secure locking mechanisms that make them difficult to force open from the outside. When tilted, they can provide ventilation without compromising security.
- Weather Tightness:
- These windows are often more weather-tight than outward opening windows because the seals are compressed by the wind, enhancing their ability to prevent drafts and water ingress.
- Space Utilization:
- Inward opening windows do not protrude outward, which can be beneficial in areas with narrow walkways or where exterior space is limited.
- Aesthetics:
- They can provide a clean and modern look, often with less visible hardware on the exterior.
Considerations
- Interior Space:
- Since the windows open inward, they require unobstructed interior space. Furniture placement and window treatments must be planned accordingly to avoid interference.
- Cost:
- Inward opening windows, especially tilt and turn windows, can be more expensive than standard outward opening windows due to their complex mechanisms and higher quality requirements.
- Maintenance:
- The mechanisms in tilt and turn windows may require periodic maintenance to ensure smooth operation.
Types of Inward Opening Windows
- Tilt and Turn Windows:
- These windows have a dual hinge system allowing them to either tilt inwards from the top or swing inwards from the side.
- Casement Windows:
- These are hinged at the side and open inward, like a door. They can be single or double casement windows.
- Hopper Windows:
- Hinged at the bottom and open inward from the top, these are often used in basements or bathrooms for ventilation.
Applications
- Residential Buildings: Common in European homes due to their practicality and versatility.
- High-Rise Buildings: Facilitate easy cleaning and maintenance.
- Public Buildings: Ideal for schools, hospitals, and offices where secure ventilation is required.
Conclusion
Inward opening windows offer a blend of practicality, security, and aesthetic appeal, making them a suitable choice for various applications. When planning for these windows, it’s important to consider the interior space requirements and potential costs to ensure they meet the needs of the building and its occupants.
