Flush Sash windows

Flush sash windows are designed to replicate the look of timber. The sashes close into the frame and finish flush with the face of the window. This provides a smooth finish to the exterior of the window and will improve the appearance of any property. They are a popular choice with homeowners wishing to recreate the attractive look of timber and also with homeowners who want an alternative to standard casement windows.
