Floating Floor Gap In Doorway?

Hello, If we are building a floating floor in the studio, the control room and the small sound lock in between, how are we to maintain the isolation gap between the floors? How do we bridge the separated floors in the doorways so that there is not a big visible gap when you open the door? We're at a loss here and the books we have don't go in to that detail. Thanks!

Couple of ways to do it... Steve

Excellent. Thanks for the diagrams. That helps immensely.

FYI, floating floors are generally no longer recommended around here except in very specific circumstances, and if and only if they are engineered properly. Most floating floors that are believed to be engineered properly are most likely not. It seems you have an active thread in the design forum. You may want to start a project thread here in the Construction forum as well where you can transition the focus of your project from design it to building it. Once you have that, you can keep all your questions together in your project thread. This is important because the answers you receive will be more targeted to you and your specific situation... What's right for your case may not be right for another, and vice-versa. 8) --Keith :mrgreen:

Sha, Thanks for writing. Just a little confused. I've never once read that floating a floor is no longer recommended. By whom? Can you advise with any suggestions on how to do it right? Something constructive, perhaps? John Sayers even recommends in his reference manual to float floors. I'd love to see documentation you have that it's not effective. Thanks. PS. Keith, any insight to my question?

Hi, sorry that I'm hijacking this thread a little, especially on my first post, but i've just been doing a sketchup diagram which was asking pretty much exactly the same question. Background Information: I am a student and I'm lucky enough to have convinced my parents to add an extention to our house for a small studio room. I want to be able to achieve as much isolation as possible from the rest of the house, so that I can have my audio levels within the extention reasonably loud. I don't expect full isolation, but "TV level" in the nearest rooms would be a good target. I am currently reading my way through Rod Gervais' book and its been a great help. One thing that has been drilled into me is the need for 2 leaf walls, which are not attatched to one another to achieve maximum isolation. I won't go into too much detail here, as this is just a post to sketch out some ideas of the more detailed construction elements. However, there is one section of wall which needs to be joined together, but this would mean attacthing the "studio" complex to the existing house. Attatched is an image of what I'm trying to get at. Basically I *think* I need to keep the leftmost walls isolated from the ones to the right, as the right ones fall within the "studio" and the left are part of the existing house construction. The wall can not be left "open" though, as it would look a bit odd with a gap in the wall! Sorry if this is a bit vauge. Feel free to ask for any details.

I'm not equipped right now to dig up the many threads here where experts have dismissed the importance of floating floors, and in fact have often recommended against them. I'm posting this via a smartphone with a screen the size of three postage stamps... :roll: Do some searches and you'll find 'em. Much has been discussed and learned here since I came on this scene over two years ago. Some recommendations have changed as we've gained wisdom. Buy Rod's book and see what he has to say about them. Read my monster thread and you'll see how I abandoned plans for several floated floor systems. In short, it's not my burden of proof "against," it's your burden of proof "for." --Keith :mrgreen:
