Wood framing is very rigid, resulting in the undesirable transmission of sound energy. For sound control, the resilient channel must be fastened directly to the stud and have insulation in the stud cavity.
There are two types of channels that are produced: one has a single leg, the other a double leg. To function properly, the resilient channel should be installed perpendicular to the support framing. For walls, the channel spacing is 24 inches on center. For ceilings, the spacing is determined by the support framing. If the spacing of the support framing is 24 inches on center, then the resilient channels should be 16 inches on center.
If the support framing is 16 inches, the resilient channels can be 24 inches on center. Should the intended finish be a spray texture, the spacing for the channel should be limited to 16 inches on center. Nails should never be used when fastening resilient channels to the support framing. Resilient channels can cantilever a maximum of 6 inches. This may vary by manufacturer and the profile of the intended channel. There should be a slot in the channel that must be centered over the support framing.
Fix the first layer of boards to the bars with self-tappers of the right length to go into the resilient bars note: NOT the timber framework , but not so long as to touch the timbers. Stagger all joints and cover the whole wall or ceiling except for 3mm gaps at the outside edges. Then add the second layer, overlapping the joints and using longer screws that will go through both two layers and into the web of the resilient bars, but again without being so long that they reach the timbers.
Mark the positions of the resilience bars and timbers on the walls to help you ensure that the screws for the second layer hit the bars and not the timbers. As a final check, before you finish off and decorate, make sure that the wall or ceiling surface flexes slightly.
If it doesn't then the fixings have compromised the movement of the resilient bars. This will probably have been caused by one or more screws having gone into the timber frame or the wall instead of the corrugated web mesh of the resilience bar. If so, this needs to be resolved before continuing or the wall will not be anywhere near as effective in insulating against noise. Fill the gaps around the edges with acoustic sealant and smooth off with a caulking tool or filler knife.
Then finish off the plasterboard joints in the usual way. Skim if required and then decorate. View our full range of soundproofing products including resilient bars. We provide our services nationwide through our in-house network of local engineers I engaged Nova at the outset of my project which I recommend you do to assist with providing a detailed material specification and installation guidance.
There was always someone available to help with practical enquiries and advice I had Adam come round to a property which i thought was beyond repair. He gave sound advice with exact details of what needed to be carried out in the most cost effective manner.
Once the works were carried out he returned, tested it I have worked with the team at nova on a number of projects and have always been very helpful and competitively priced. Highly recommend this company for any sound test and report.
Excellent service, engineer was very informative and helpful. Good customer service being able to speak to knowledgeable people on the telephone when making inquires about the procedure involved for the sound testing of our property Very attentive and friendly service, keen to serve the client, and absolutely not about dragging the case out for fees - will work to save the client fees, and understand the practicalities of the case and the opposition that applications Adam was very attentive and very professional answered all my questions and returned all calls the engineer arrived at the time agreed and again explained everything before carrying out the test , and we received our report within couple Its a tricky area and you need the right support, Paul Robinson brought Adam's team to the table and we'll be working together again in future for sure.
Although we had followed the building reg, in terms of sound insulation the property conversion still failed the sound Test. Adam was very helpful and professional and guided us to the point that when it was retested again we passed. Excellent service and communication with all the members of staff we had dealings with. A very professional approach and attitude by all.
An experience that is refreshing within the building sector and a company I could recommend Excellent service by Adam and the team at Nova. The service they delivered was efficient, competitive and I would highly recommend them! Step 4. You should now have a Resilient Bar installed every — mm across your ceiling joists fixed securely on the thin flange end with the other end free hanging. A minimum of a 25mm Drywall Screw should be used to fix your bars to your joists.
Step 5. This final step is the finish to todays guide. You will now securely fix your plasterboards to the resilient bars, ensuring that you fix only to the metal edge that is suspended and not through the edge and into the joist, as this would remove any acoustic advantage this system has to offer.
