Flush or Stormproof

We offer two versions of wooden casement window. Flush casements (or traditional) where the window or sash sits flush to the frame and stormproof which sits proud of the frame and ensures additional protection from bad weather. Both options perform equally well due to our team’s excellent research and development skills and tested design process.
