Hi...
1. Is this insulation equivalent to the rockwools AFB or any other 2.5-3 pcf (40-48 kg/m3) insulation. It´s the only one in Sweden i can find. The specs are in Swedish but i think you can figure it out:

2. Regarding floor construction, most designs i´ve seen has plywood on their studs as a floor construction. Is it possible to use 22mm particleboard instead. (it´s a moneything =)..)
What will be the advantages/disadvantages??
thankful for replies.. take care
Two questions on building products...

1 - I'm glad your english is great, my swedish is non-existent - still, yes that looks like the right stuff - be careful NOT to use any of their "EPS" stuff, or Encapulated Poly Styrene - they also seem to carry that type product, which is NOT good for acoustics. The page you linked is the stuff you need.
2 - IF this is a FLOATED floor, the only thing to watch for is spacing of the framing and resilient pads - on the first page of Aaron's thread on floating floors (REFERENCE section, top of construction forum) I outlined a method of finding out usable spacing for pads - that thickness of particle board should be fine, you may want to consider 400mm joist spacing instead of 600mm since particle board has less bending strength than plywood or OSB. Particle board is, however, denser than plywood and so should have a lower resonant frequency (good thing) for the same thickness.
The stuff in your link will be fine for filling between joists in the floor also - it needs maybe 5-10 mm of compression to keep the floor resonance under control.
One more thing - most particle board here in the US is made with a formaldehyde based glue, and will outgas a known carcinogenic for a few weeks - if that part of the floor won't be SEALED with either floor paint, varnish, vinyl, etc, you should leave the building open and use several fans to ventilate the room for at least a week - better to just use a heavy sealing layer over it, especially if it's really cold outside.
Some more expensive types of particle board now use NON-carcinogenic binders, but they ARE more expensive - if you don't ask, no one will tell you which type you're looking at... Steve

Thanks Steve... looks like i can always count on you for some reasonable answer... 
I´m sure keeping away from the polystyrene.. thanks anyway...
The floor is non existing yet, but it will be a floated floor.
I´ve already read the floating floor sticky, but i think i´ll have to go over it a couple of times when i´m actually starting to do some construction.
The glue thing wouldn´t be to hard to find out about... and here is where my english knowledge ends..carcinogenic!!??..=).. but it doesn´t sound to healthy.... but i am gonna have a vinylfloor ontop of it so that should do it or??
many thanks from Sweden
