uPVC Sash Windows in Hertfordshire & London

Sash windows, box sash windows or sliding sash windows, as they are sometimes called have stood the test of time due to their elegant style and versatility. Originating in the 17th century, they dominated the window industry throughout the country for over 400 years. Being the window of choice meant they were often tolerated for their short comings. However, their popularity began to wane somewhat after the end of WWII, many being replaced with alternative styles. Although still popular with many, the appeal of sash was at an all-time low, mainly due to their inherent problems, which included sticking and rattling, allowing draughts and dust to enter homes, and continuous maintenance. With the introduction of uPVC as an alternative window manufacturing material in the 1980’s, the sash window has be given a new lease of life. Subsequently, uPVC sash windows are now common place in properties all over the country.
