ᐅ Determine the installation position of the window

Hello everyone,

We have completed the measurement appointment with the window installer on our shell construction.
We need to decide on the best position for installing the windows. We are building without roller shutter boxes on top of the window frames, since our house is naturally shaded by many trees. Because we have flush-to-ceiling lintels on both the ground and upper floors, we prefer to use the space up to the ceiling for window area. However, we want to keep the option open to add shading later if needed, either with roller shutters installed inside the reveal or, if necessary, mounted on the facade.

Currently, our plan is to have the windows installed as shown in the sketch attached. Is there anything that you think speaks against this approach?

Thank you very much for your feedback.

We currently have two quite large patio doors planned for our living area.
1.: Height: 2.55 m (8 ft 4 in) Width: 3.20 m (10 ft 6 in)
2.: Height: 2.55 m (8 ft 4 in) Width: 2.40 m (7 ft 10 in)

I would align the visual lintel height of the windows accordingly.

@11ant .. the things you always remember 😉 ... and that’s how I would do it too 😉

Hehe. Currently, the wall openings are designed so that all lintels are flush with the ceiling. This also applies to the two large terrace doors. If we proceed as recommended by 11ant, we would extend both the windows and the terrace doors up to the ceiling to keep it uniform.

The questions we are currently considering are:

- The taller windows/terrace doors will let in more light, which is good. On the other hand, we are not sure if the absence of the traditional lintel above the windows (which, in our case, would have been integrated above the roller shutter box) might cause aesthetic issues when viewed from the inside.

- Where is the best position for the window within the reveal (wall thickness) to minimize thermal bridges, and related concerns?

To avoid thermal bridges, the window should be positioned within the insulation layer or directly on the interior side of it. For monolithic constructions without an insulation layer, it should be centered with the interior surface. So, your drawing basically shows the correct placement.

However, the additional insulation over the lintel on the window frame is missing. This should extend 3-5 cm (1-2 inches) beyond the top of the frame on the exterior side if there is no shutter box, so that the window is sealed against the insulation on the inside.

I don’t understand why a shutter box should be installed within the visible area of the window.
