Hush Bar Deep: Soundproofing resilient bars for separating floors/ceilings and walls

The Hush Bar Deep #resilient bars are highly effective #acoustic products to be used when refurbishing properties.
It optimises acoustic performance in separating floors/ceilings and walls by virtually decoupling a lining from a ceiling/floor or floor structure. This helps to reduce significantly reduce sound transmission paths through #floor and #walls structures.
Hush Bar Deep resilient bars are attached to the underside of timber and metal joisted construction at 600mm or 450mm centres. Suitable for all kinds of #refurbishment, #conversion and new build projects, the bars create a larger void within a #construction and allow for high mass boards to be used.
Using Hush Bar Deep ensures the acoustic treatment complies with all relevant UK Building Regulations - Approved Document E (England and Wales), Section 5 (Scotland) and Part G (Northern Ireland). They can also be used as part of a Robust Detail ceiling system.
Hush Bar Deep dimensions:
30mm deep x 120mm wide x 2.4m or 3.0m length
Overall depth of the bar is 30mm

Where is the foam cushioned decoupling brackets, this is a flawed system. The sound insulation will not work in this instance.

[@florintrifan935]

For RCs there is a path to transmit vibrations through the screw contact area but it's very small, here the horizontal cuts make the "decoupling", which still do a nice job, even if not so well as RCs, they are better suited for all types of ceilings, especially for standard heights in apartment blocks where the height is at 100inches or 2.5m. Obviously, you cannot afford to lose 20 inches or 50cm from this height. There is nothing more nerve-braking than to see how all youtube videos present wooden joists, with wide and deep empty spaces, just good to be filled up with fiber-glass insulation, as if the basement ceiling is the same as the roof. Well, this may be the case only in US, and even there, I'm pretty sure there are many brick buildings, with concrete floors, no wood unless in the country side.
Still, all youtube videos which are clearly ads for their own companies show these annoying wooden joists, which I've seen only in vacation and only when going into the mountains, other than this all my acquaintances live either in brick houses with concrete ceilings, or in concrete apartments blocks with -obviously, concrete ceilings. While you may say, well if it's from concrete it's already soundproof, it's not the case for 5" concrete, you can hear all the steps and all conversations even if not understanding what they are talking about.
Your companies will never be successful until you have the courage to tackle the apartment blocks and brick houses with concrete ceilings which -if from 2nd half of 20 century will have lower ceilings, so they can afford to lose maximum 1.5-2 inches.

What are RCs?

It’s not a proper isolation. The real slab is not decoupled from the isolation

[@Lolatyou332]

Yeah, for best isolation you'd really need to use this bar with decouplers that attach to the drywall. I think the RC1s are probably better than this because it has more room to vibrate than these.

@@Lolatyou332yes! I used isomax clips with 25ga hat channel NOT RC2
