  • The Durodeen cill extender features a built-in drip groove to direct run-off water away from base of window.
  • Timber cills are often the first thing to rot on a window and need replaced, Durodeen cill extenders will not rot and can be retro-fitted to your existing cill.
  • Pre-machined sill extenders - helping you achieve a better finish more similar to wood than extruded profiles.
  • Durodeen cill extenders enable you to produce better quality windows faster, with less labour time required.
  • Excellent paint adherence and finish - as the profile is machined giving an etched surface rather than the shiny 'non-stick' surface created by extruding.
  • Doesn't rot, shrink or warp - increasing the lifespan of your windows and reducing site callbacks.
  • Ends do not breakout or splinter - less waste.
Note: Non-Stock Durodeen product can take between 5-6 weeks to be delivered from point of order.
