Window with movable mullion - a modern solution for more space and a better view

Choosing the right windows is a key part of a home's interior design and functionality. Windows with a movable mullion are becoming increasingly popular, providing not only better aesthetics but also greater convenience. What exactly is a movable mullion and what are the advantages of this solution? Check whether it is worth investing in such windows!

What is a movable mullion in a window?

In traditional double-hung windows, there is a fixed vertical element - the so-called mullion - which divides the window into two parts. In windows with a movable mullion, this element is integrated into one of the sashes. This means that when both sashes are opened, there is no visible division, allowing a wide, unlimited space.

Advantages of windows with a moveable mullion:

  • More space and a better view
    When the window is opened, you get a wide, undivided opening, which provides a panoramic view to the outside.
  • More light in the room
    The absence of a fixed mullion means that more natural light enters the room, making the room brighter and more spacious.
  • Aesthetics and modern design
    Windows with a movable mullion look modern and elegant, fitting both classic and modern interiors.

Where do windows with a movable mullion work well?

  • In living rooms and large living rooms – hey allow a beautiful view of the garden or terrace.
  • In kitchens – they facilitate ventilation and make the room more comfortable to work in.
  • In office premises – more natural light supports concentration and improves working conditions.
