Flush sash windows – clean look with classic style

Providing the slim sightlines of traditional timber without the need for sanding, varnishing and general maintenance, our flush sash windows come engineered in versatile uPVC to perfectly blend the old and new.

The style takes its name from how the panel sits perfectly “flush” within the frame, delivering a clean, sophisticated look.

However, flush sash windows don’t just look good – made of high-performance modern materials, they also provide twenty-first century energy efficiency, helping homeowners keep the cold at bay in winter.
