Hi Thomas,
Thanks for the reply:-),
Please look at the links,you will see the floor construction of the cdm-iso-lat http://www.cdm.be/documents/pdfs/cdm-iso-lat.pdf .
I intend to use light concrete(B

Hi Sui-City,
The total floor is 20,71 m2, the total mass that the floor can handle 3500kg with a factor of 1,3 so the max. will be 4550kg.
I hope it is possible to isolate the room without a very heavy construction.
I hope that this will answer your question.
Thanks,
Peter

Have you looked at Getzner's Sylomer Elastomer?

Good advice there. Three / four brands to look at in Europe: -Gretzner with Sylomer series -BSW with Regufoam series -AMC Mecanocaucho (note so it's clear: we work with them a lot as we import their stuff to the Benelux... They are partners of Gretzner too since they use Sylomer in a lot of their stuff) -Merford noise control @ Peter: forget green-glue for now, it won't save you. You need the basics of mass-air-mass properly covered first. Green Glue is only a way to make the system work better in some situations. It comes second to a healthy plan.

Hallo Thomas,
I always thought that the use of greenglue would have the effect of doubling the mass.
What would be the best approach for my home studio, within the limits of my room.
(I know that i need a big floating floor, but I can't:-(, that is why I thought about a thin floating concrete floor as basis for the metal stud drywall walls). Cause I suppose it would be better than a wooden floating floor.
best regards,
Peter

Don't count on that. Have a proper classical system designed first, then use green glue as an extra if budget allows and if the conditions are such that it will be efficient. Which isn't always so obvious. PeterDraaisma wrote on Wed, 08 September 2010 15:21 |

Have you considered hiring a local acoustician to make a few measurements and estimate what would be the extra soundproofing needs? That would help in defining what can be and if it can be done. Regards,

Cause i have to work within the limits of my house i have the intention to use metal studs instead of wood studs with two of three layers of drywall. I suppose you mean with classical system a wood stud wall-system as described in build it like the pro's.
If I measure with an db-meter in my room and by the neighbours listing to music at the same volume, will this give an indication about the amount of isolation is required? I informed for an acoustical measurement but that is about 1500 euro and i don't have the budget to work with an pro designer. And i think that the conclusion will be bad:-( and that I need as much isolation that is possible.I understand that a pro like you work with measurements but i have to do it with reason and logical thinking.
After all the reading I have done I know, and please correct me if I'm wrong, that a good floating floor is the bases for a good room in a room design.
So I would like to know if there is experience here on the forum with relatively light floating concrete floors. I would be nice if I could get some directions here on the forum.
Best regards,
Peter

Classical system means M-A-M system + decoupling. The way you build it will vary. Wood or studs, neither one is more pro than the other really.

We use a fair bit of that too PeterDraaisma wrote on Thu, 09 September 2010 14:14 | After all the reading I have done I know, and please correct me if I'm wrong, that a good floating floor is the bases for a good room in a room design.

Yes, absolutely. PeterDraaisma wrote on Thu, 09 September 2010 14:14 | So I would like to know if there is experience here on the forum with relatively light floating concrete floors. I would be nice if I could get some directions here on the forum.

"Lightweight" is a moving scale. The big issue with your project is admissible load + weight repartition. There isn't much more I can tell you. Floating is really the easy part of studio design. But it has requirements. The laws of physics say you need a certain weight to make it work with regards to your needs, nobody can change that. Maybe this could've worked well - its a "light system" - but the minimum concrete thickness has to be 82mm (without finish surface)... Which means close to 200kg/m

Hi Thomas, Thanks again for the info! I was wondering if this floating floor will be springy, should i build separate decoupled walls, so the floor can move independent from the construction. I all ready decided to hang the ceiling to spare weight on the floor-surface.(yes I will check with the constructor;- ) When I spoke with him last time he said that close to the concrete wall, the floor can handle much more weight. So i could make the wall next to the neighbours heavier(more layers of drywall) And make the concrete floor a "little" heavier. What do think about this? Best regards, Peter
