Warming and leveling the balcony.

It's no secret that our builders built, to put it mildly, crooked. After glazing and lining the balcony, I ran into a warming problem in terms of level - the distances between the corrugated board and the crate were different, but I did not want to use the mineral wool because of its hygroscopicity. I had to cut the foam into pieces, and fill the gaps with mounting foam. it turned out a monolithic insulation plate with a thickness of 5 cm. 7 foam cylinders of 0.75 liters were used for this, and another 1.5 cylinders to support the inner lining (used proliferated plywood). The size of the balcony is 1x3.5 m.
