This is the answer to the question What should be considered when remodeling the attic of a two-family house?
Revision 1
We did the insulation between the rafters ourselves. Basically, it's a diligent job. Nothing is absolutely complicated. You need insulation material. Cut it with an insulation knife, build a cutting table on the floor from plywood and stampboards. The plywood can be used later for something else.
When the felt is laid everywhere, and the corners or crevices are well filled, put a vapor barrier film over it. Use a good membrane that allows moisture to escape, called a climatic membrane.
Tape the joints well with foil tape, floor and wall joints with foil cartridge adhesive. Support the foil with boards that are screwed to the rafters. If desired, you can lay drywall on top of it.
