Replacement windows are the perfect option to refresh and modernise dated exteriors, which is why we offer a wide range of window styles, materials, and colours to suit you and your East Midlands home.

As one of the most popular window styles amongst our customers, it’s time to address the benefits of uPVC sliding sash windows. Sophisticated, stylish, sustainable, and suited to a wide variety of property types, here are the top 4 benefits of sliding sash windows.

1. Safe and secure sliding sash windows

Home security and safety are paramount for you and your loved ones, which is why we’re dedicated to installing quality sliding sash windows that use long-lasting, stylish, and secure window hardware, furniture, and fixings as standard.

Sourcing our sliding sash windows from the UK’s leading sash window manufacturer, our sash windows incorporate a range of industry-leading security measures for complete peace of mind, including:

  • Strong 5 chamber design
  • PAS 24 security specification & Document Q performance as standard
  • Window locking systems that exceed building regulation criteria
  • Premier glazing from industry leaders Planitherm
  • They can also be fitted with child safety limit stops to restrict opening & further Secured by Design upgrades, if required.

2. Excellent energy efficiency provided by sliding sash windows


Combined with premier double glazing from industry leaders Planitherm, our sliding sash windows are guaranteed to enhanced thermal and acoustic performance wherever they’re installed, achieving U-values as low as 0.8W/m2k.

What’s the importance of a U-value to you? In simple terms, a U-value is the rate of heat transfer through any element of a building. The lower the U-value, the more energy-efficient it is – so our sliding sash windows are incredibly efficient!

3. Charming period details on sliding sash windows for authenticity

All sliding sash windows from the Nottingham Window Company include charming period features including fully mechanical joints, deep bottom rails, 85mm Edwardian, Georgian and Victorian slim mullion combinations as well as authentic run-through window horns. Run-through window horns are part of the structure of the window itself and make for a more authentic appearance when viewed up close by visitors and passers-by.

4. Sliding sash windows approved for use in conservation areas & listed buildings

Not all uPVC sliding sash windows are suitable for restricted areas like conservation areas. With 174 conservation areas just in Nottinghamshire, restoring essential character within period properties doesn’t have to be a chore with The Nottingham Window Company. Improving exterior and internal aesthetics alike, uPVC vertical sliders add instant heritage charm and value to newer properties too.
