Resilient Channel Ceiling Spacing

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.

Resilient channel ceiling spacing. You want the ceiling to be able to float. Knurled face makes screw attachment of wallboard easier. 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. 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.

Don t hang your wall board tight to the ceiling. However there s a myth that says resilient channel can t support multiple layers of gypsum wallboard in floor ceiling assemblies. 610 mm 24 in 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.

If the spacing of the support framing is 24 inches on center then the resilient channels should be 16 inches on center. For joists 406 mm 16 in o c and 406 mm o c. Joists with 5 8 type x with zero problems. If your ceiling joists are spaced every 16 rdquo.

If you re looking to avoid ceiling cracking the industry s leading authority is recommending resilient channel as a solution. I have done 24 spacing with 16 o c. 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. You can certainly space the resilient channel every 24 rdquo.

For joists 610 mm o c. Sound clips and hat channels. It is best to use 32 mm 1 in type w or s screws but never nails to fasten channels to joists. As i have mentioned many people believe the sound clips and hat channels method to be a more effective decoupling.

Note that all of the lab test data with rc is based on 24 on center. Rc deluxe is the preferred resilient channel because of its extra wide 1 1 2 flange for the installation of the gypsum board. Will provide additional structural support with a minor loss in sound performance you probably wouldn rsquo t notice the difference. However if you are using 2 x layers of drywall spacing the resilient channel every 16 rdquo.

To function properly the resilient channel should be installed perpendicular to the support framing. Resilient channel should be installed perpendicular to the. Resilient channels should be attached to the ceiling joists at right angles as follows. It is used as a cross furring member for resilient attachment of gypsum.

Ink jetted to assist in proper installation orientation. For the resilient channel to do its job it needs to be away from the framing at the edges also. For ceilings the spacing is determined by the support framing.
