Max' Studio - First impressions & questions

Looking good! One point I might make (maybe it is too late), but it seems like you are not using enough Green Glue to me. They suggest 3 tubes per 4X8 sheet of drywall, with 2 tubes per sheet being a cost-saving solution. Best of luck, you are getting there!

Guys, I don't want to put anyone on a downer, but Ro - Is it me, or does the method of assembly that appears to be shown in image 5014 scare the hell out of you too? :shock: :shock: :shock: If those MDF boards are fixed to the joists above, and the channel only to the MDF, albeit with spacers, I wouldn't trust 12mm or so of screw thread into MDF to support the massive weight of the plasterboard that appears to be going up! Sorry - I couldn't bear to learn of a disaster later whilst having this feeling now. I was going to start this post with, "Woah woah for God's sake hold on a minute!" What do you think Bro? Regards, Lou. 8)

Thanks doublehelix! I'm aware of this GG thing. Its just that I had to do the even cheaper cost-saving solution :D . And still I would venture to say that this is better than doing nothing or 3/4 layers of drywall instead of 2. But thanks for the comment! Lou: I'm glad you defused your first sentence :-) No, seriously, thanks for making these thoughts. You may have a point there. On the other hand I can't imagine that this connection should be too weak. Let me explain it: The RC is attached to the MDF ceiling at every 20 cm and there are 4 channels for the ceiling at a distance of 57cm that hold a 1,70m drywall board. The MDF is attached to the joists sufficiently (hopefully?). If I were to hang small drywall plates with 20x57cm (skrew distance in RC x channel distance) I wouldn't feel any risk of having them fall down to the floor some day. So why should I fear this with the boards at big size? Please let me know if this makes sense!??

Guys, as there are coming so many useful answers from you "builder" in this construction forum I don't wanna isolate from my design-kinf-of thread. See here! : http://www.johnlsayers.com/phpBB2/viewtopic.php?t=11341 Any comment appreciated!! Thanks

How many layers of drywall are you planning to hang from that RC? And what thickness? How much does each layer weigh per square meter? How many screws are supporting it? Do the math, and see how many Kg you have hanging from each screw. Then find out how much force is needed to pull out one screw from your MDF. Then add in a huge safety margin. I share Lou's concern: I'm not sure if I would want all those Kg of drywall hanging over my head, supported only by a few screws embedded in MDF, which might weaken and crumble over time... (temperature changes, humidity changes, vibration from high SPL levels for prolonged periods, etc...) Maybe you need to find a structural engineer who can tell you if you have enough structural integrity there for safety. [/quote]

When I saw the pic of the RC I had the same feeling, Lou Furthermore, for ceilings I'd advise to have the RC space 30cm instead of 60cm or you'll have sloppy hanging ceilings in no-time (gravity is a biatch) Could you provide a closer, detailed pic of the ceiling/RC construction?

My first thought looking at the sketchup of the roof, was that this roof has two leaves existing even before the rc and additional layer of rock is installed. So the RC isn't helping.

:roll: Yeah, X, I warned the man already. Dunno why we lost focus on that. Good call.

loose the "federschiene" and add gypsumboards directly to your roof, else you'll end up with a multi-leaf ceiling. The "federschiene" are NOT resilient (if that's your goal) if you mount'm like the pic says. There's also a little "space" between the soft fibre wood plate.. loose that too by lifting the wood plate. Else you'll have a resonation panel in your construction.. Add more MASS if you will by adding gypsum in between the joists.

Those that fail to learn from history are doomed to repeat it?

Hello after a long time! I'm finally sitting in the final studio and it's amazing ! I'm having so much fun and space in here! Compared to my 8 sqm dark cellar room this i like a rebirth! One point on the recent discussion about the ceiling. I respect your comments and critisism here a lot! I added only one layer of drywall now made some calculations. The way the ceiling is build now must be ok! I already had some sound checks running an the first impression is superb! Measuring coming up soon as well as preparations with absorbers. Have a look for yourself. Thanks for all the support fo far! Matthias

If it sounds half as good as it looks it fantastic. Congratulations. Andre
