Window calculator
Measure each window. Pick the type, material and colour, enter the sizes and add each window to the list. The drawing changes with you and the table adds up the square metres.
This calculation gives the area, not a price. The price depends on what you agree with the installer.
- Tilt and turn: opens to the side and tilts for fresh air.
