Vertical sliding windows, also known as sash windows, have been gracing British homes for centuries. Today’s modern versions combine timeless aesthetics with cutting edge technology, offering homeowners and installers the perfect blend of traditional style and contemporary performance.
If you’re considering updating your windows, here are five compelling reasons why vertical sliders could be the perfect choice for your home.
-
Traditional Charm Meets Modern Performance
Traditional sash windows are a quintessential feature of period properties, but modern vertical sliding windows offer so much more. Today’s designs maintain the classic appearance while incorporating:
- Advanced UPVC and aluminium profiles for superior insulation
- Smooth sliding mechanisms
- Tilt in features for easy cleaning
- Multi point locking systems for enhanced security
Whether you live in a modern or a traditional property, vertical sliding sash windows are an excellent choice for your home.
-
Enhanced Energy Efficiency

Modern vertical sliding windows are designed with energy conservation in mind. To ensure that they help to optimise your home thermal performance, they incorporate the following features into their design:
- Double or triple glazing options
- Thermally efficient frames
- Weather tight seals
These features can lead to reduced heat loss compared to traditional timber sash windows and lower energy bills and improved comfort.
-
Low Maintenance and Durability
Unlike their timber counterparts, UPVC and aluminium vertical sliders require minimal upkeep.
- No painting or varnishing needed
- Wipe clean surfaces
- Resistant to warping and rotting
- Long lasting performance
- UV stable materials that won’t fade or discolour
In some situations, such as in listed buildings or conservation area properties, you may need to use timber windows. At Great Harwood Windows, we now offer our customers a range of high quality timber products.
