Classic Elegance Meets Modern Efficiency

When something fashionable in the Georgian period was resurrected in the Victorian era, carried through Edwardian times and is still seen as a stylish yet functional part of architectural home design today, you have to accept that sometimes they get things right the first time – and sliding sash windows are such a thing. The traditional classical aesthetics have remained the same, bringing timeless class and elegance to many buildings but the windows themselves have been developed for enhanced energy efficiency, including double or triple glazing, high-quality seals, low-emission glass and tighter fitting sashes reducing gaps and potential for drafts.

Why Choose UPVC Sliding Sash Windows?

Unplasticised Polyvinyl Chloride (UPVC) sliding sash windows offer several benefits, making them a popular choice for both new constructions and replacements in existing buildings.

Low Maintenance

UPVC sliding sash windows require very little maintenance compared to traditional wood sash windows. They do not need to be painted or varnished and are resistant to weathering, warping and rotting. Cleaning them is as simple as wiping them down with a cloth.  


Durable & Weather Resistant

UPVC is a highly durable material, resistant to corrosion, rot and pests, helping the sliding sash windows have a long lifespan with minimal degradation.  UPVC is highly resistant to various weather conditions, including rain, wind and sun. Unlike wood, it does not swell, warp or crack in extreme weather, maintaining its integrity over time.  


Typically, UPVC sliding sash windows are more affordable than wooden or aluminium alternatives. This cost-effectiveness, combined with their durability and low maintenance needs, makes them an economically attractive option 

Efficiency and Style Combined: UPVC Sliding Sash Windows

Elevate Your Home's Aesthetics

Modern UPVC sliding sash windows are available in a range of finishes and colours, including options designed to mimic the appearance of traditional timbers. This gives them the versatility to be used in various architectural designs from contemporary to classical. Installing high-quality UPVC sliding sash windows can enhance the overall value and appeal of a property, even more so when it improves energy efficiency and lowers household running costs.

Energy Efficiency & A Greener Choice

UPVC is an excellent insulator and, when combined with double or triple glazing, can significantly improve the thermal efficiency of a building, helping to reduce heating and cooling costs. 
While UPVC is a plastic product, advances in recycling technologies mean that UPVC windows can be recycled and reused at the end of their lifespan, reducing their environmental impact.

Added Security & Insulation

UPVC sliding sash windows can be fitted with high-quality locks and robust hardware. The strength of the material, combined with these security features, can enhance the overall security of your property. 
UPVC windows, especially when double or triple-glazed, offer excellent sound insulation. This makes them an ideal choice for homes in noisy areas, such as built-up areas or busy streets.
