ᐅ Issue with Calculating the Parapet Height When the Worktop Runs Into the Window

Kitchen window with countertop running into it:

We have an issue calculating the sill height.

The countertop should have a working height of 97.5 cm (38.4 inches). How high does the window sill need to be for this to work?

Here is my calculation:

The countertop will extend in front of the window frame so that later on there is no gap between the bottom edge of the window frame and the countertop.

So we calculated:

97.5 cm (38.4 inches) - 3.5 cm (1.4 inches) profile below the window (?? is 3.5 cm correct here ??) = 94 cm (37 inches)

94 cm (37 inches) - 1 cm (0.4 inches) = 93 cm (36.6 inches), because the kitchen floor will likely settle a bit due to the 8 cm (3.1 inches) insulation in the screed, causing the kitchen including the countertop to lower slightly.

93 cm (36.6 inches) - 1 cm (0.4 inches) construction tolerance = 92 cm (36.2 inches)

Sill height = 92 cm (36.2 inches)

Does this make sense?

Many thanks in advance ... Christian

Can you install the cooktop deeper then?

No, but we tried it with tall pots. It fits well.

... It would be nice if we could return to my original question ...

Should the countertop extend into the window frame so that the window can just still be opened, or should it be installed directly below the window frame?

In the latter case, the sill height is the countertop height plus the floor build-up. In the first case, it’s the same minus the frame.

Or am I missing something? It seems too simple somehow.

That can’t be right. There is always a mounting profile installed under the window. So the window sits a few centimeters above the sill height (sill height = top edge of the uppermost brick course).

Do you want to do the masonry yourself?

The sill height is usually the top edge of the window sill... it doesn’t really matter to me how the window is installed according to current standards, usually with brackets... the window is installed at the appropriate height after the shell construction. This is specified in the execution plans by the mason and the window manufacturer.

In the kitchen, the countertop will take the place of the window sill material. The calculation is done the same way as for your marble bench at the neighboring window. This task is handled by the same people.
Overall, the working height is equal to the sill height, depending, of course, on the material of the countertop.
