Hello to all you wise ones!!!
We are about to sign a contract any day now, planning to build a house in aerated concrete, and we've reached the stage where we need to decide what interior walls to choose. I'm not sure whether to go with interior walls in aerated concrete or walls with studs, insulation, and plasterboard plus either board or råspont.
Which should we choose????? Does anyone know the pros and cons????? What is the difference between using råspont or board in a "regular" interior wall, i.e., which provides better sound insulation, etc.???
I'm feeling completely confused and don't know what to choose, so if anyone has tips or experiences to share, it would be great!!!

Interior walls made of wooden studs and insulation with a surface of board plus gypsum are very good when it comes to sound insulation, feel, and making it easy to hang things on the walls. I think it's a better option than lightweight concrete specifically for interior walls.
Difference between raw plywood and board? Not much, really. The board wall ends up a few millimeters thinner, and it's significantly faster to put up board construction panels than to nail raw plywood. In terms of sound and comfort, they are equivalent, as well as in terms of strength.

A lot of questions: 
Do you always put up walls with gypsum outside board? Is it because of fire safety that you do it? Or is it easier to get gypsum completely smooth? If you put the board on the outside, is it easier to hang things on the walls than if the gypsum is on the outside?
Are 13 mm gypsum boards the ones most commonly used?

markis said:A lot of questions:

Yes, almost. Some house manufacturers, like Smålandsvillan, go directly on chipboard. But most commonly, it's plasterboard on the outside. The reasons you have listed below.
Is it due to fire safety that it's done? Or is it easier to get plaster perfectly smooth?
Yes.
If you put the board on the outermost layer, isn't it easier to hang things on the walls than if the plaster is the outermost?
Nah.. I usually hang my stuff on nails that are longer than 13mm anyway..
Are plasterboards usually 13 mm?
Yep. 6mm is used when renovating and it's too much work to do a lot of filling.
So: The difference in time for a "standard" wall between leca/gypsum is very large. Masonry takes time. After completing the masonry, you probably want a smooth surface on the wall, and then we're talking gypsum again... You probably have both electricity, phone, TV, etc., that you want to hide the cables for in the wall, and the time to rout that into the leca becomes very expensive. The price difference is probably at least 100%. Use gypsum.
Boardskiva is not an OSB or plywood but a soft board that is used in, for example, certain bulletin boards, etc., and is yellow. OSB or plywood is generally referred to as "construction board," and that's what you should have behind the gypsum. You gain nothing from having gypsum behind the construction board... If you only have plywood, you won't find a painter in this country willing to stand and spackle your walls... Use studs, insulation, plywood, and gypsum in that order. The plywood makes the wall more robust and you avoid problems with mounting things. Sure, the gypsum is 13 mm, but use long screws or nails, and you won't have any problems with fittings.
