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

... what is meant by the 3.5 cm profile ... The window is placed on the last brick using a kind of profile. I believe this profile is about 3.5 cm (1.4 inches) high. Does anyone know more precisely?Maria16 schrieb:
... height from raw floor level It is the height from the finished floor level.Maria16 schrieb:
The sill height is the same throughout our house, and we have a lower overall kitchen height; could it be that only your kitchen window has to be installed higher than the others? That’s correct, the kitchen window is installed a bit higher so the countertop can be high enough...C

Kitchen cabinets usually have adjustable feet that can compensate for a significant height difference. So I think 5–10 cm (2–4 inches) is generally not an issue. In extreme cases, you can also place something under the feet. The important part is just not to have it too low, especially concerning the windowsill. But a 2 cm (0.8 inch) difference probably doesn’t matter much, in my opinion. This is not about the windowsill. The window height must be precise so that the countertop can fit properly and have a height of 97.5 cm (38.4 inches).

what I meant was the window shouldn’t be installed too low. Other than that, it doesn’t really matter.
Starting from the kitchen ceiling, the roller shutter box and the window are subtracted (including tolerance for window installation), then you already have the height of the window sill.
Then you only need to calculate how many centimeters (inches) there are from the top edge of the finished floor to the specified window sill height.
Otherwise, enlighten me!

Knallkörper19 Jul 2018 15:36I would set aside the ceiling height for now.
With a countertop height of 97.5 cm (38 inches) and a thickness of 4 cm (1.5 inches), the underside would be at 93.5 cm (37 inches). Then I would add 2 cm (0.8 inches) for the smoothing layer, adhesive, and tolerance, so the rough opening height would be 91.5 cm (36 inches) above the finished floor level. Using rough opening and finished floor level together is a bit unusual, so you should discuss this again with the builder. You also need to check the thickness of the window’s mounting profile. For us, there is about 8 cm (3 inches) of profile below the closed sash – which for you would mean there is still a 2 cm (0.8 inch) gap between the opening sash and the countertop.
PS: A countertop height of 97.5 cm (38 inches) is quite tall. Are you sure about that?
