Seal-Lite Group now manufactures the Flush Casement Window from Swish.

Gerald Allen, marketing manager for Epwin Window Systems, said: “Seal-Lite has been a Swish fabricator for several years and we’re looking forward to continuing to work with them and helping them get the most out of everything this product range has to offer.”

Chris Shearn, director of Seal-Lite Group, said: “Everything about the Flush Casement Window is quintessentially British. The aesthetics, colour options and practicality of the window is perfect for both heritage and contemporary homes and it was an easy decision to add it into our portfolio. We are delighted with our choice.”
