Ventilation is a crucial factor when choosing windows for your home. It not only affects the air quality but also the overall comfort of your living space. As a supplier of extra large double hung windows, I often get asked how these windows compare to awning windows in terms of ventilation. In this blog post, I'll break down the differences between the two and help you decide which one is best for your ventilation needs.
How Extra Large Double Hung Windows Work for Ventilation
Let's start with extra large double hung windows. These are the classic windows that most of us are familiar with. They have two sashes, one on top and one on the bottom, and both can slide up and down. This design gives you a lot of flexibility when it comes to ventilation.
You can open the top sash to let out hot air that rises naturally, following the laws of thermodynamics. Warm air tends to be lighter than cold air, so it moves upwards. By opening the top sash, you create an escape route for this hot air, which can significantly improve the air circulation in a room.
On the other hand, opening the bottom sash allows fresh air to enter at a lower level. This creates a cross - flow of air, which is great for ventilating large areas. When the top and bottom sashes are open simultaneously, you get what's called a stack effect. The warm air exits from the top, and the cooler air rushes in from the bottom, creating a continuous and efficient airflow.
Extra large double hung windows are particularly effective in rooms where you need to control the direction of airflow. For example, in a living room with furniture arranged in a certain way, you can adjust the opening of the sashes to direct the air exactly where you want it. And because of their large size, they can provide a substantial amount of ventilation, even in bigger rooms.
How Awning Windows Provide Ventilation
Now, let's talk about awning windows. These windows are hinged at the top and open outwards from the bottom, kind of like an awning. When you open an awning window, it creates a sort of canopy that allows air to enter while also protecting against rain.
One of the great things about awning windows is their ability to provide ventilation even in wet weather. Since they open out at an angle, rainwater is less likely to splash inside. This is perfect for areas that experience a lot of rainfall or for bathrooms, where you might want to keep the window open for ventilation while taking a shower.
Awning windows are also excellent for drawing in air from the outside. The angled opening creates a pressure difference that helps to pull air into the room. They are especially effective in smaller spaces or rooms where you want a more concentrated airflow. For instance, in a utility room or a small office, an awning window can quickly refresh the air.
Comparing Ventilation Performance
When it comes to comparing the ventilation performance of extra large double hung windows and awning windows, several factors come into play.
Airflow Volume
Extra large double hung windows generally offer a larger opening area, which means they can move more air in and out of the room. This is a huge advantage in large spaces or areas with poor natural ventilation. If you have a big open - plan living area or a warehouse - style loft, the large opening of double hung windows can ensure that fresh air reaches every corner.
Awning windows, however, usually have a smaller opening area. While they can create a strong airflow due to the angled opening, they can't move as much air as extra large double hung windows in terms of sheer volume.
Directional Control
As mentioned earlier, extra large double hung windows give you more control over the direction of airflow. You can open the top and bottom sashes independently to create different patterns of air movement. This is useful in rooms with specific ventilation requirements, such as a kitchen where you might want to direct the cooking fumes out.
Awning windows offer less control in this regard. They mainly draw air in at an angle and are better suited for general air intake. If you don't need to direct the airflow precisely, an awning window can do a great job of bringing in fresh air.
Weather Resistance
In terms of weather - related ventilation, awning windows have the edge. They can be left open during light rain because of their angled design. Extra large double hung windows, on the other hand, need to be closed when it rains to prevent water from getting inside. However, some modern double hung windows come with weather - stripping and other features to reduce the risk of water infiltration, but they still don't offer the same level of protection as awning windows in wet conditions.
Other Considerations
Energy Efficiency
Both types of windows can be energy - efficient if they are properly installed. Extra large double hung windows can be sealed well to prevent air leakage when closed. And when it comes to ventilation, the stack effect created by opening both sashes can help reduce the need for air - conditioning in the summer.
Awning windows also have good sealing properties. Their design allows for a tight fit when closed, which helps to keep the indoor temperature stable. However, if they are not installed correctly, the angled opening can sometimes lead to air leakage.
Aesthetics and Space
The choice between extra large double hung windows and awning windows also depends on the aesthetics of your home and the available space. Extra large double hung windows have a classic look that can complement a wide range of architectural styles. They are also great for rooms with limited exterior space since they open vertically.
Awning windows have a more modern and unique look. They can add a touch of style to your home, especially if you have a contemporary design. However, they do require some exterior clearance to open fully.
Conclusion
In conclusion, both extra large double hung windows and awning windows have their own strengths when it comes to ventilation. If you need to ventilate large areas, have precise control over airflow, and don't mind closing the windows during rain, extra large double hung windows are a great choice. On the other hand, if you want to ventilate in wet weather, have smaller spaces to ventilate, or prefer a more modern look, awning windows might be the way to go.
