Why uPVC Sash Windows?

uPVC sliding sash windows outperform traditional timber sash windows in every area. They are a much more modern alternative and will add value to your Croydon property. Although timber designs are the traditional style of choice, they are now more outdated. They do not offer the levels of security, thermal efficiency and customisation that uPVC alternatives provide. What’s more, timber also requires regular upkeep and maintenance due to its lack of the ability to withstand wet weather. Save yourself time and money.

Our uPVC sash windows also boast a range of health benefits. Our double glazed sash windows use ventilation technology to help improve the air quality within your home. This inflow of fresh air helps to aid breathing, which is particularly important for those who may suffer from asthma or other lung conditions. The natural circulation of fresh air also improves sleep quality and prevents poor ventilation issues such as mould and damp.

uPVC Sash Window Styles

Our dedication to providing our customer’s with the finest products has lead us to partner with market leaders Masterframe. Masterframe supplies us with their Bygone collection which consists of three styles of double glazed sash windows to install into homes in Croydon and the surrounding areas. Each style will provide you with high performance and functionality.



The Symphony sliding sash window is a premium design option. This style provides a complete replica of timber sash windows, making it the perfect addition for a home that requires an authentic installation. The Symphony style is tried, tested and approved by leading industry security experts. This is due to its steel reinforced sashes and additional security features included as standard. If you are looking for the ultimate uPVC sash window design, this is it.



If you are looking for a versatile sliding sash window design, the Harmony window may be ideal. This innovatively designed double glazed sash window can be outfit with a range of optional extras for individual customisation. This allows you to tailor your windows to meet your requirements and budget. The Harmony design also features the same authentic woodgrain finish as the Symphony style.



If you are looking for a uPVC sash window style that offers outstanding value, our Melody design may be the perfect fit. It is a cost effective double glazed sash window installation that offers exceptional style and performance. The Melody features the same frame and sash profiles as the Harmony and Symphony, but with less included additional features.
