If you’re considering new windows for your home, you might have come across the terms “mulled” and “non-mulled” windows. Understanding the difference between these two types can help you make an informed decision.

What Are Mulled Windows?

Mulled windows are multiple window units that are joined together to form a single large window. This can include combining two or more windows of the same or different types, such as casement, double-hung, or picture windows, to create a cohesive look.

Key Features

  • Unified Appearance: Mulled windows provide a seamless, unified look by combining multiple windows into one larger unit.
  • Increased Light: They allow more natural light to enter the room, creating a brighter and more open space.
  • Versatility: Mulled windows can be customized in various configurations to fit different spaces and design preferences.
Pros Cons
  • Creates a larger, more open view
  • Enhances natural light in the room
  • Offers a unified, aesthetically pleasing look
  • Customizable configurations
  • Can be more expensive than single windows
  • May require additional structural support
  • More complex installation process
  • Potential for more seams, which could require maintenance

What Are Non-Mulled Windows?

Non-mulled windows are individual window units installed separately. Each window functions independently and is framed individually.

Key Features

  • Individual Units: Each window operates independently, allowing for different types and sizes in various locations.
  • Simpler Installation: Non-mulled windows are typically easier and faster to install because they are individual units.
  • Cost-Effective: They are usually less expensive than mulled windows, both in terms of product and installation costs.
Pros Cons
  • Easier and faster to install
  • Generally more affordable
  • Independent operation for each window
  • Flexible placement and design
  • May not provide the same cohesive look
  • Less natural light compared to mulled windows
  • Individual framing can take up more space
  • Separate units might not look as seamless

Choosing Between Mulled and Non-Mulled Windows

Before making your decision, here are a few factors to consider:
  • Aesthetic Preferences
  • Mulled Windows: Ideal if you want a large, uninterrupted view and a cohesive look. They work well in living rooms, dining areas, or any space where you want to maximize natural light and the view.
  • Non-Mulled Windows: Suitable if you prefer the flexibility of having individual windows. They are great for spaces where different types of windows are needed for functionality and design.
  • Budget
  • Mulled Windows: Typically more expensive due to the complexity of joining multiple windows and the potential need for additional structural support.
  • Non-Mulled Windows: Generally more budget-friendly and easier to install, making them a cost-effective choice.
  • Installation and Maintenance
  • Mulled Windows: Installation can be more complex and may require professional expertise. Maintenance might be needed for the seams where the windows are joined.
  • Non-Mulled Windows: Easier and quicker to install. Maintenance is straightforward since each window is an individual unit.

Expert Tips and Advice

Choosing the right type of window for each room in your house can make a big difference in comfort, style, and functionality. Here are some expert tips to help you decide:

Consider Room Function

Think about how each room is used and what kind of windows would be most practical.
  • Living Room: This is often the heart of the home, where you entertain guests and spend family time. Mulled windows can create a stunning, open view and let in lots of natural light, making the space feel larger and more inviting.
  • Kitchen: For the kitchen, consider how much ventilation you need. Non-mulled windows, like awning windows, can be great here because they open fully to let in fresh air.
  • Bedroom: Privacy is key in bedrooms. Non-mulled windows, such as double-hung or single-hung windows, can offer the flexibility of opening the top or bottom sash for airflow while maintaining privacy.
  • Bathroom: In bathrooms, privacy and ventilation are crucial. Non-mulled windows with frosted glass can provide privacy while still allowing some light to enter. Small awning windows high on the wall are also a good choice for ventilation.

Amount of Natural Light Needed

  • Living Room and Dining Area: These spaces benefit from lots of natural light. Mulled windows can be perfect for creating bright, welcoming areas where you spend a lot of time during the day.
  • Home Office: A well-lit workspace is important for productivity. Mulled windows can help flood the room with natural light, reducing the need for artificial lighting during the day.
  • Bedrooms and Nurseries: While natural light is great, you also want the option to control it. Non-mulled windows with blinds or shades can give you the flexibility to darken the room when needed, such as during nap times.
Different rooms require different amounts of natural light.

Privacy Considerations

Privacy is another important factor when choosing windows.
  • Bathrooms and Bedrooms: These rooms need more privacy. Non-mulled windows with options like frosted glass or internal blinds can help maintain privacy while still allowing light in.
  • Living Rooms and Kitchens: These areas typically need less privacy, so larger mulled windows can be used to create open, light-filled spaces without concerns about prying eyes.
