I am building a passive house in Hammarö, and doing it in aerated concrete.
Walls from the outside:
Reinforced fiber plaster
Insulation 15cm
Aerated concrete 36.5cm 275kg/sqm
Reinforced natural gypsum plaster
I am currently building the part that has a terrace on the upper floor. I would appreciate suggestions on how to make the roof watertight. My preferences are that I should be able to do it myself, for example with some form of rubber sealing membrane that can be self-leveling compound on and then lay tiles or wood on.
Example sketch:
Roof from the outside (example):
Tiles
Self-leveling compound
Some sealing layer
Metal for gutters (along the edges)
Aerated concrete slab (beams) - along the edges it is reinforced with edging stone, and a cast concrete edge
Insulation
Can anyone suggest what would be the best choice of sealing layer in this case?
I am also considering how to smartly insulate the roof from the inside, any tips?
