Good evening,
when measuring the windows, we found that a frame extension is necessary because the outer opening is significantly smaller than the inner opening of the window.
Now, the windows are of course supposed to have an external roller shutter!
The following question came up: Is the guide rail of the external roller shutter included in the frame extension? Or will the guide rail later disappear behind the smaller outer opening in the masonry? These are my concerns!
Can anyone with experience help me here?
Here is an example:
Outer window opening (width): 850 mm (33 inches)
Inner window opening (width): 1000 mm (39 inches)
Left margin from inner to outer opening: 70 mm (28 inches)
Right margin from inner to outer opening: 80 mm (31 inches)
With a frame thickness (system Iglo 5 is 74 mm, but here 70 mm (3 inches) for easier calculation), if 2 cm (0.8 inches) are supposed to protrude into the outer opening on both left and right sides (visible outer frame), I would have to add 100 mm (4 inches, 50 mm (2 inches) on each side) to the dimension of the outer opening. So the window rests with 5 cm (2 inches) on the left and right. Now the frame extension is added to fill the missing area so that the window can be installed properly. That is 2 cm (0.8 inches) on the left (7 cm (2.8 inches) - 5 cm (2 inches)) and 30 mm (1.2 inches) on the right (8 cm (3 inches) - 5 cm (2 inches)). 1 cm (0.4 inch) on each side for mounting material is left out here for simplicity.
How does the external roller shutter and its guide rails behave in relation to the frame extensions?
In theory, the guide rails should also become wider by the width of the frame extension so that the rails do not disappear behind the smaller outer opening.
Please help!
Best regards and thanks in advance!

Hello,
I’ve managed to grab a picture from Google here. Tomorrow, in better lighting, I can also post a photo of the windows.
This concerns the dimensions A and I. A is smaller than I, as can be seen in the picture. What is marked as max. 5 cm (2 inches) in the image measures 9.5 cm (4 inches) on the left and 8.5 cm (3.3 inches) on the right in my case.
Regards

Sebastian791 Aug 2016 22:01Why is it done this way? Are you installing the windows yourself?
Why do you do something in a certain way? I don’t quite understand you right now.
Yes, I want to install the windows myself, of course following the current technical standards as much as possible. That means using the necessary sealing and insulation materials to secure the windows within the reveal.
