Why choose Flush Sash windows from Definition?
FlushSash windows, or otherwise known as Flush Casement windows, are a hugely popular choice for those seeking a traditional timber 1930's style window, with all of the modern benefits of uPVC thermal efficiency. We offer both The Heritage Collection and Liniar Flush Sash range - giving you a huge selection of profiles, colours and finishes to choose from.
What are the benefits of Flush Casement windows?
-
THERMAL EFFICIENCY - Our Flush Casement window ranges are all rated A for thermal efficiency and can achieve a U-value of 1.2
-
TRADITIONAL STYLE - Flush Casement windows offer all of the modern functionality of a 21st century uPVC window, but with the look of a traditional timber flush window. The sash sits flush with the frame, giving a completely seamless look. Flush Casement windows date back to the 19th century where they were commonly found on Georgian, Victorian and Edwardian properties.
-
DURABILITY - All of our Flush Casement windows are made from industry-leading uPVC and have an average lifespan of at least 25 years. Unlike traditional timber windows which often end up suffering from rot, uPVC is completely weather-proof and highly durable.
-
LOW MAINTENANCE - You can have the look and feel of a traditional timber window without the high maintenance. Timber windows tend to suffer from cracking, rot and damp after a certain period of time - and are also difficult to clean. uPVC is easy to clean, extremely weather resistant and requires little maintenance.
-
SECURITY - All of our Flush windows come with industry-leading hardware including stylish key-locking handles and multi-chamber window frames. The PVC-U profile used to create these high spec windows has been independently assessed
and has BS kitemark and BBA accreditation, it achieves BS7950 and PAS 023/024 for security and BS6375 wind and water testing.
