At ETC, our Flush windows are fully compliant with Building Regulations in conservation areas. Our uPVC flush sash windows capture a beautifully traditional aesthetic, offering revamped performance in terms of thermal-efficiency, security and maintenance. These three factors are heavily associated with problems of heritage homes in the past, which is why we offer our cost-effective uPVC flush sash windows as an outstanding solution. The design replicates traditional painted timber, which is virtually indistinguishable from the original window.
