Designed to replicate the look of traditional timber with all of the modern functionality that uPVC provides, they make a cost-effective and worthwhile investment for your home.

Flush casement windows date back to the 19th century where they were the hallmark of British architecture in Georgian, Victorian and Edwardian properties. Throughout the 1950s the trend continued, with double glazing becoming available and window designs evolving into more modern styles. Nowadays, you can opt for uPVC or aluminium flush casement windows that have over taken timber windows in terms of performance and benefits.
