You are seeing it wrong. The stone is 17.5cm and each window is 2cm away from the outer edge. Enough clearance on the inside.I am just wondering why the windows are flush with the interior masonry. Because that actually creates a thermal bridge, or am I seeing that wrong
It's not about the clearance inside, the window should be flush with the insulation on the outside.You are mistaken. The stone is 17.5cm and each window is 2cm away from the outer edge. Enough clearance inside.
it's not about the play inside, the window should be on the same level as the insulation outside.
There will now also be insulation in front, and exactly at the corner of the window and insulation, the masonry is then not really insulated (possibly 2-3 cm). The window should have been recessed by about the thickness of the masonry insulation so that everything is insulated evenly and no thermal bridges occur.I’ll take a look in the energy document. It said how to install the window to achieve value X.
There will be insulation added in front, and exactly at the corner of the window and insulation the masonry is then not really insulated (possibly 2-3cm).
The window would have had to be set back about the thickness of the masonry insulation so that everything is evenly insulated and no thermal bridges occur.
A 3cm insulation board is going to be installed on the window reveal.
Now my knowledge is exhausted. I will inquire.
