we have a 4-meter-long window section that will be placed in a lecamurad-wall (29 cm isoleca). When reading the design guidelines for isoleca, you see that the longest they recommend for a masonry beam is 3 meters....
What to do? Form, reinforce, and cast the beam in concrete? Order a ready-made concrete beam from the factory? Steel beam?

steel beam or factory-made....Lecabalk is my choice.... a steel beam often needs more insulation, and that can be tricky, for example, high risk of thermal bridges,,,,
I would probably go for a lecabalk if the concrete factory can guarantee its strength.....
It's very easy to convert a lecabak to finished space... just take plaster putty,,,(cheap) and do what you want with the surface....
