Resilient Channel Ceiling Spacing

If the spacing of the support framing is 24 inches on center then the resilient channels should be 16 inches on center.

Resilient channel ceiling spacing.

For ceilings the spacing is determined by the support framing. Resilient channels should be attached to the ceiling joists at right angles as follows. Knurled face makes screw attachment of wallboard easier. If you re looking to avoid ceiling cracking the industry s leading authority is recommending resilient channel as a solution.

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. Joists with 5 8 type x with zero problems. For joists 406 mm 16 in o c and 406 mm o c. If your ceiling joists are spaced every 16 rdquo.

For walls the channel spacing is 24 inches on center. For the resilient channel to do its job it needs to be away from the framing at the edges also. However in the field it is difficult to keep this spacing consistent. However there s a myth that says resilient channel can t support multiple layers of gypsum wallboard in floor ceiling assemblies.

Sound clips and hat channels. For joists 610 mm o c. 610 mm 24 in o c. However if you are using 2 x layers of drywall spacing the resilient channel every 16 rdquo.

Rc deluxe is the preferred resilient channel because of its extra wide 1 1 2 flange for the installation of the gypsum board. 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. Ink jetted to assist in proper installation orientation.

Resilient channel should be installed perpendicular to the. Note that all of the lab test data with rc is based on 24 on center. It is best to use 32 mm 1 in type w or s screws but never nails to fasten channels to joists. You want the ceiling to be able to float.

You can certainly space the resilient channel every 24 rdquo. It is used as a cross furring member for resilient attachment of gypsum. 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. I have done 24 spacing with 16 o c.

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