Flush Sash Windows

The beautiful flush casement design gives the exterior of your window a flush appearance. The opening window closes flush into the outer frame, so it sits in line with the face of the frame, rather than standing proud, meaning there’s no visible lip when looking at your window from outside. Home Glaze flush casement windows also feature a Smoothweld almost invisible joint on the frame corners. The result is an attractive, aesthetically pleasing appearance that gives your home a modern look similar to the contemporary, slim styling of aluminum windows. Flush casement windows are becoming increasingly popular, due to their neat clean lines and flat finish.
