Resilient Channel Ceiling Spacing

Single leg resilient channel made of 25 gauge steel rc 1 pro is one of the most effective low cost methods of improving sound transmission loss through wood and steel frame partitions.

Resilient channel ceiling spacing.

Joists with 5 8 type x with zero problems. You can certainly space the resilient channel every 24 rdquo. However in the field it is difficult to keep this spacing consistent. Resilient channels should be attached to the ceiling joists at right angles as follows.

If your ceiling joists are spaced every 16 rdquo. For joists 610 mm o c. While we re not sure where the myth originates evidence shows that resilient channel attached to the underside of floor joists can successfully support two layers of 1 2 inch or 5 8 inch gypsum wallboard. 610 mm 24 in o c.

For joists 406 mm 16 in o c and 406 mm o c. You want the ceiling to be able to float. For ceilings the spacing is determined by the support framing. As i have mentioned many people believe the sound clips and hat channels method to be a more effective decoupling.

For walls the channel spacing is 24 inches on center. Knurled face makes screw attachment of wallboard easier. If the spacing of the support framing is 24 inches on center then the resilient channels should be 16 inches on center. I have done 24 spacing with 16 o c.

If you re looking to avoid ceiling cracking the industry s leading authority is recommending resilient channel as a solution. Resilient channel should be installed perpendicular to the. For the resilient channel to do its job it needs to be away from the framing at the edges also. Single leg resilient channel made of 22mil steel rc deluxe is one of the most effective low cost methods of improving sound transmission loss through wood and steel frame partitions.

Sound clips and hat channels. The gypsum association released a technical document ga 227 13 recommendations for the prevention of ceiling cracking their publication outlines methodologies for mitigating cracking in large span gypsum board ceilings due to fluctuations in temperature. Rc deluxe is the preferred resilient channel because of its extra wide 1 1 2 flange for the installation of the gypsum board. Ink jetted to assist in proper installation orientation.

Ranges over 24 are against the installation instructions while spans less than 24 ensure that the resilient channel will not be as effective as it is in the lab. Note that all of the lab test data with rc is based on 24 on center. However there s a myth that says resilient channel can t support multiple layers of gypsum wallboard in floor ceiling assemblies. Don t hang your wall board tight to the ceiling.

However if you are using 2 x layers of drywall spacing the resilient channel every 16 rdquo. Will provide additional structural support with a minor loss in sound performance you probably wouldn rsquo t notice the difference. While resilient channels are meant to be attached directly onto the studs sound clips provide an added checkpoint the vibrations need to pass before reaching the hat channel.
