Soundproofing Walls Ceilings Using Resilient Channel

For soundproofing purposes there must be insulation within the wall or ceiling cavities.

Soundproofing walls ceilings using resilient channel.

This method can be used for both floors and walls. Resilient channel should be mounted at a right angle to the framing while installing on walls and ceilings. While the resilient channel is a metal bar with holes the hat channel is shaped like a hat from the front view. Resilient channels sometimes abbreviated as rc or z channel are some of the most common components installed on projects requiring additional soundproofing higher stc ratings while they provide a significant improvement in decoupling the structure borne noise in walls they should not be seen as a panacea for all noise issues.

Resilient channels are installed horizontally or perpendicular to the studs. It is also referred to as a furring channel. How to install resilient channel. However even having resilient channels will result in a significant noise reduction.

Using clips and hat channels would add even more points to your setup. Make sure all the flanges are pointing in the same direction i e. The channels should be spaced no more than 24 in. So mainly due to the fact that the soundproofing benefit are similar to rc1 but it can handle more mass is why rc2 is more commonly used.

Resilient channels are used to decouple the drywall sheeting from the structural framework of a building. Adding green glue between two sheets of drywall on top of that would increase the method s soundproofing efficacy even more. Furring is a technique that is used to level out walls and ceilings with metal channels. A hat channel is a framing piece that is used within walls and ceilings.

If you re considering adding having two drywall layers with a resilient channel in between your contractor is probably going to recommend a rc2 resilient channel over rc1. The decoupling element of soundproofing involves separating the framing in the ceiling to break the sound pathway hence reducing noise. In the case of our ceilings that solid path is in the form of joists or studs. Sound isolation clips vs resilient channel absorption.

Fasten the resilient channel to studs using 1 1 4 in. In soundproofing the very most common approach to block transmission of noise is through the decoupling where the primary focus is to trap or change the medium of transmission of noise and the very best effective solution to achieve that is using a resilient channel. Mount channels with the drywall flange up. Isolation clip and studs how to soundproof existing walls windows ceilings the second method is to insert resilient sound isolation clips between ceiling and additional drywall.

The main advantage of this method is that it is less expansive and easy to use. While using with walls make sure to mount the channel with narrow flange along the bottom and the larger flange on the top.
