When choosing windows for your home, there’s a lot to consider. You want something that looks good, works well, and will stand the test of time. Vertical sliding windows, also known as sash windows, tick all these boxes. They combine classic styling with practical features and modern performance, making them an excellent choice for both period properties and modern homes.

We’ve seen firsthand how these windows can transform a home, adding character while providing better efficiency and functionality.

What Are Vertical Sliding Windows?

Vertical sliding windows, or sliding sash windows, feature two frames that slide up and down. Unlike casement windows that open outward, these windows slide vertically within the frame. This traditional design dates back centuries but has been updated with modern materials and technology.

Style

Traditional Charm with Modern Materials

Vertical sliding windows are a key feature of Georgian, Victorian, and Edwardian architecture. If you own a period property, installing these windows can help maintain its historical character. But even in newer homes, they add a touch of timeless style.

The good news is that you don’t need to use traditional timber to get this classic look. Our aluminium and uPVC sash windows look just like the real thing, with authentic details like deep bottom rails and sash horns. They are far more efficient than old windows and can completely transform the warmth, comfort, and cost of heating an older home. Plus, they won’t warp, rot, or need regular painting like timber.

Customisation Options

One of the best things about modern vertical sliders is the range of customisation options available. Our windows come in over 60 colours, including popular choices like anthracite grey and various woodgrain finishes. This means you can match your windows to your home’s style, whether that’s a faithful period recreation or something more contemporary.

Beyond colours, you can choose:

  • Different grid patterns to match Georgian, Victorian, or Edwardian styles
  • Decorative sash horns for added authenticity
  • Various hardware options and accessories
  • Glazing bars in different configurations

These options let you create windows that are uniquely yours while still maintaining the traditional sash window look.

Conservation Area Suitability

If your home is in a conservation area, your choices for window replacement are limited. However, our vertical sliding windows are often approved for use in conservation areas because of their attention to detail and authenticity. This means you can have a traditional style that is approved for use and receive all the thermal benefits of modern windows.

Functionality

Excellent Ventilation

Vertical sliding sash windows offer a unique advantage when it comes to airflow. Opening both the top and bottom sashes allows cooler air to enter through the lower opening while warmer air naturally rises and escapes through the top, creating a continuous flow of fresh air. This helps to cool your home in summer without harsh draughts, and in winter, it allows for gentle ventilation without letting too much heat escape.

Our sash windows feature an innovative ‘tilt-in’ function, allowing you to angle the sashes slightly inward. This gives you even more control over airflow and is useful when you want fresh air without fully opening the window.

Modern Energy Efficiency

Traditional sash windows were known for being draughty, and because of this, many period and heritage homes are expensive to heat. Our modern versions solve this problem completely. With multi-chambered uPVC frames or thermally broken aluminium frames, combined with high-performance double or triple glazing, our vertical sliders offer excellent thermal efficiency.

This improved energy efficiency means:

  • Lower heating bills
  • A more comfortable home
  • Reduced carbon footprint

Common Questions About Vertical Sliding Windows

What’s the difference between UPVC and aluminium vertical sliders?

UPVC vertical sliders tend to be more cost-effective and offer excellent thermal efficiency. Aluminium versions have slimmer frames, allowing for larger glass areas and more light. Both materials provide great performance in different ways and come in a range of colours.

Can vertical sliding windows be installed in any home?

Yes, a sash window system can be installed in most properties. They’re particularly well-suited to period homes but can also add character to modern buildings. The installation process is similar to other window types.

How do vertical sliding windows compare to other window styles for energy efficiency?

Modern vertical sliding windows can be just as energy efficient as other styles. With advanced glazing and thermally efficient frames, they can achieve excellent energy ratings.
