It's been some time since I last updated the thread. Here's just one new picture:
New rooms in Portugal-img00356-20100916-1128.jpg
the walls have reached their full height, and the projection/machine room is already built.
Next week, concrete slabs, floated on Rockwool.

Hi Branko!

Everyone around here is very curious about your project! So don't forget to upload more often and of course mooooooore pics!!

If you cover it well I'm sure this could be a thread that will inspire and be a source of info for everyone who's pursing to build a studio in the future!

Keep the good work it looks promissing!

Cheers,

Artur

Ok, I just returned from a two week trip - here's the news:

this is the future machine room, situated below the projection room.

And this is the beginning of the front wall for the recording studio's control room:

You can see the position of the corridor that leads directly to the studio, and the opening for the control room entrance door.

Ground floor: Dubbing Theatre and Recording Studio, Clients area, reception desk
First floor: 3 editing rooms, office

One editing room will be dedicated to picture processing, other two can serve for both picture and sound. All rooms will have the same monitoring system. A bigger monitoring system (same brand) will be installed in the Rec Studio's Control Room.

You place rockwool inside the brick walls in order for sound not to resonate on the air cavity

Hi, Branko

What is the building regulation in Portugal related with the foundations and the walls?
I am looking to do something similar with our new rooms but i am afraid it is not possible with all these earthquakes in Greece

Thanks, Nikolas

No, the Rockwool prevents cement from falling down between the walls. We have to assure there's absolutely NO contact between walls, as well as no piling up of cement at the wall base. Walls are floated on Sylomer, and if anything bypasses that floating layer, the effect will be completely lost. The cheapest way to achieve this is to put some Rockwool between those walls.
The distance between walls is 5cm, so it would be impossible to pull out any garbage that fell between the walls.
Resonance in such a small cavity between two super-heavy (2,5 tons per meter) walls isn't something that worries me.

On top of the walls, a "crown" is made. Horizontal wood beams will fit into these slots, to support the "lid"

Floor

Hello, first i want to thank you for this post, this very intresting for people who wants to isolate her room.

I have some questions about the floor.

How do you made your floating floor?
Do you bluid the floor first?
or the wall first?
Old 28th September 2010
  #42
These walls are isolation walls and they are not connected to future studio floor. We built the isolation wall first.
The next step is to build a concrete slab, which will be the base of the studio floor. The slab is floated on a 10cm layer of Rockwool, which will serve as spring. Our slab will be 12 cm thick, with iron mesh reinforcement inside.
Studio walls (inner shell) will be built on this floated concrete slab, thus completely isolated from the rest of the building structure.
Watch this thread, in the next 2 weeks we'll pour the concrete slabs for both rooms.

I am talking generally about why ones uses rockwool between walls.. .it also acts as a thermal sound insulation product and shifts the resonance frequency to a lower range. (check http://www.isover.lv/file/pd/awg_paper_CH_1.pdf)

I have made and seen dozens of projects in Portugal for building acoustics, not in one you won't find rockwool or other absorbent material between walls.

Great thread, that's an amazing build you've got going on.

I've been to Lisboa several times between 1999 and 2007 doing service calls on small cruise ships. I love the sidewalks, the bars and the ladies, a great great city.

It would be wonderful to see your studio on my next visit.

Best of luck to you and keep the photos coming.

Dear Andre,
I'm sure Rockwool has those properties you're talking about, but I repeat: The purpose of this layer between the walls is ONLY to prevent cement from falling down. If there's a cheaper way of controlling that problem, I'll be happy to apply it.
Please, note that in this construction, there's no Rockwool that is exposed to studio users.

Now, as we're talking about Rockwool (or any other mineral wool product) use in sound insulation, I'll draw your attention to the title of the paper you suggested for reading:
The acoustic role of glass wool in a double-leaf lightweight wall

where the word ligtweight immediately dismisses any practical implementation of those conclusions in the case of my construction. While we can admit that, in theory, between these walls there is a resonant cavity, the mass of the air/rockwool combo is completely insignificant compared to the huge mass of the wall itself. Most of the transmission loss of this system happens in the wall itself, as it is difficult to move that mass due to it's rigidity.

In conclusion: while, in theory, I may or not agree with some of your points, I cannot understand what was the meaning of your post. For a moment, I thought you're suggesting something was wrong in the concepts we used....

Here are some new photos - we started cleaning up the place.

Today, we have some more news.

First of all, the Dubbing theatre walls are done, and the scaffolds are removed, except those by the rear wall, where the wall isn't finished yet.

Second, we began to prepare things for the concrete slab pouring. Two layers of Rockwool are being cross-laid on the structural floor. Each one is 5cm thick, and when the concrete is poured over these, the weight will compress them to 8cm in total.

12cm of concrete on top of this will give us a 20cm floor slab, on top of which we'll build our studio.

Third, the projection/machine room building progress is visible:

These wood beams will support the floor for the projection booth. On the lower level, we'll have a machine room.

Hi everyone!

The beams are ready to receive the Viroc floor panels.

Not much productivity these days - tomorrow is a major public holiday in Portugal and an important anniversary - 100 years of Republic!
Practical meaning of the above is that when you have a holiday on Tuesday, nobody really works on Monday....


Anyway, here's the detail of the floating structure:


New rooms in Portugal-_mg_9702.jpg

So, we have two layers of 75Kg/m3 Rockwool, 50mm each, we have Rockwool around the perimeter that will serve as formwork for the concrete.
On top of the Rockwool, we put a layer of PVC foil, to prevent concrete from penetrating into Rockwool.
On top of the PVC, we put light wood boards, to allow us to walk on it without smashing the Rockwool, and to protect the PVC when we put a wire mesh on top of it.



And here's some nasty weather in Lisbon on Sunday...

Bad luck! The weather turned colder and wet just as you needed it hot for the concrete slab! (well, not too hot, either, otherwise the concrete stresses and cracks)

Are the wooden beams enough for the projection booth? Does that mean you'll only have digital projection?

So, if I got it straight, the PVC is protecting the Rockwool, and the particle boards are protecting the PVC from the wire mesh. Is that right?

What's the wire mesh for?
Old 7th October 2010
  #56
Those wooden beams can hold a ton at such a short span, but you're right: no 35mm projector will be installed. It's been a while since I had to turn on the projector in our current studio (OBVIOSOM in Lisbon), and I don't see a tendency other that replacing 35mm with DCI systems in commercial theatres.
The wire mesh (or would that be rebar cage?) is used to reinforce the concrete slab and to prevent cracking due to pressure on edges, which will support the inner shell walls.

Anyway, here are some pictures of men at work, cutting and placing Rockwool layers, PVC layers and protective OSB layer, before the concrete reinforcement cage:

It's only now, with scaffolds removed we can see the real size of the recording studio:

The progress on the stairs to the projection booth is a bit slower than expected:

I'll keep you updated, it's becoming interesting now... It's been two months of concrete blocks and bricklaying, now moving on to timber, plasterboard and chipboard.

We're speeding up these days. The definite day for concrete pouring is Thursday, so everything needs to be cleaned up until then.

Rebars are in their place in the Recording Studio, on Monday and Tuesday we'll place them in the Dubbing Theatre as well.

My goodness, this is some installation! You goal is to have a real professional commercial studio, isn't it?

Would you like to have some hollow chambers dedicated for acoustic reverb, like CBS (I think) had? That would be very special.

Anyway, as all the others have said, keep up the great work!
