The Rundfenster is a custom-made circular (or oval) window available in wood, uPVC, or wood-aluminum hybrid frames.

It serves as an elegant architectural element — ideal for attics, bathrooms, staircases, gables, or any space needing natural light and a distinctive design touch.

The round shape offers a softer aesthetic and can be customized in size, glazing, and opening style.

Design and Customisation
You can configure the window to suit your needs: choose frame material (wood, uPVC, wood-aluminum), glazing type, size (diameter or oval dimensions), and opening mechanism (fixed glass, pivot/swing, tilt).
Because of the round shape there is no conventional bottom sill — installation requires a circular or arched opening in the facade.
These windows are often used as fixed decorative/light windows or as operable windows in attics, bathrooms, stairwells, or facade gables.

Use Cases
Bathrooms, lofts, attics, stairwells
Gables, facades, and architectural accent walls
Places where you want natural light but not huge rectangular windows
Homes needing a unique design statement with functional windows

Pricing & Ordering (Estimate)
Because each Rundfenster is custom-configured (size, material, glazing, opening type, finish), pricing varies significantly.
Customers must submit exact size and configuration to receive a quote.
Expect higher costs compared to standard rectangular windows due to custom fabrication and non-standard shape.

Installation Notes
