for Round Windows Made of Aluminum

GESCO-metall offers specially curved window sills and weather boards for round windows. These components are not only functional but also aesthetically pleasing and help protect the building from weather influences. Aluminum is the preferred material here, as it is particularly corrosion-resistant and durable. The weather boards are precisely adapted to the window profiles and provide a clean, long-lasting solution for rainwater drainage.

U-end for plaster and L-end for exposed concrete

Our window sills can be manufactured in segments, as 180° half circles, or 360° full circles. The following end options are available:

  • U-End for plaster: Ideal for plastered façades, providing a clean transition and protection against moisture.
  • L-End for exposed concrete: Perfect for modern architectural concrete. The slim, clean finish complements minimalist design and enhances linear aesthetics.
