Resilient Channel Ceiling Spacing

To function properly the resilient channel should be installed perpendicular to the support framing.

Resilient channel ceiling spacing.

For ceilings the spacing is determined by the support framing. You want the ceiling to be able to float. It is used as a cross furring member for resilient attachment of gypsum. For the resilient channel to do its job it needs to be away from the framing at the edges also.

Rc deluxe is the preferred resilient channel because of its extra wide 1 1 2 flange for the installation of the gypsum board. For walls the channel spacing is 24 inches on center. Will provide additional structural support with a minor loss in sound performance you probably wouldn rsquo t notice the difference. For joists 406 mm 16 in o c and 406 mm o c.

Joists with 5 8 type x with zero problems. If the spacing of the support framing is 24 inches on center then the resilient channels should be 16 inches on center. 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. 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.

As i have mentioned many people believe the sound clips and hat channels method to be a more effective decoupling. Knurled face makes screw attachment of wallboard easier. Don t hang your wall board tight to the ceiling. 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. Resilient channel should be installed perpendicular to the. 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. 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.

However if you are using 2 x layers of drywall spacing the resilient channel every 16 rdquo. It is best to use 32 mm 1 in type w or s screws but never nails to fasten channels to joists. 610 mm 24 in o c. Note that all of the lab test data with rc is based on 24 on center.

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. You can certainly space the resilient channel every 24 rdquo. If your ceiling joists are spaced every 16 rdquo.

I have done 24 spacing with 16 o c. Ink jetted to assist in proper installation orientation. If you re looking to avoid ceiling cracking the industry s leading authority is recommending resilient channel as a solution.
