Heritage Flush Sash Windows
Heritage Flush Sash Windows are our authentic timber alternative for period homes, cottages and conservation areas across Essex and Suffolk. Slim, timber-like proportions and a flush sash create a balanced traditional appearance, while optional mechanically jointed corners remove the visible weld line and recreate the character of a traditional timber joint.
