How to replace sills and make measurements?

The window sill comes under the frame 1-3 cm (depending on its width) and is mounted in the window sill. That is why the width should be measured from the window sill to the edge of the wall, while adding another - + 3-10 cm (depends on the material of the window sill you choose).

The length of the window sill is determined as follows: measure the width of the window opening on the inner slopes (we are talking about those that are closer to the room, since slopes can be oblique) and add - + 10 cm (- + 5 cm on each side).

The tide is an important element of the window block, designed to drain water and protect the lower slope of the window opening from the effects of weather conditions.

To prevent water from breaking the wall by getting to the lower slopes of the window opening, it must be removed and the lower slopes protected. These features handle the ebb and shutter well for plastic windows.
