Flush sash windows are characterised by slim sightlines and sashes that finish ‘flush’ with the exterior face of the window. Infusing the timeless look of classic ‘flat’ wooden windows, they incorporate all the modern qualities expected of modern aluminium and uPVC window solutions. Combined with highly-insulative double glazing, flush sash windows add a touch of pure elegance and refinement no matter where they’re installed. In keeping with period property aesthetics, they often meet the requirements of most conservation areas in Shropshire, Worcestershire and the West Midlands too.
