Resilient Channel Ceiling Leveling

Soundproofing membrane ultimately every architect needs to determine their stc requirements and the most cost effective way to meet them.

Resilient channel ceiling leveling.

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. Furring is a technique that is used to level out walls and ceilings with metal channels. Source while the resilient channel is a metal bar with holes the hat channel is shaped like a hat from the front view. In 1985 usg stopped manufacturing the resilient channel that makes up most of the lab test results today that we see.

Probably you have read our detail guide on how to soundproof wall using the resilient channel in that we learned how using the resilient channel you can set another layer of drywall on top of existing wall and can trap the noise. To install resilient channels on wood or metal framed walls one should attach resilient channels with the attachment flange down except at floor level where it should face up and at right angles to the wall studs. When correctly installed a gypsum board resilient ceiling system will slightly give when pressure is applied. As an acoustical consultant we typically recommend rc for gypsum ceiling assemblies under open web truss and concrete decks.

It is also referred to as a furring channel. If you re looking to avoid ceiling cracking the industry s leading authority is recommending resilient channel as a solution. The real solution involves the installation of furring strips either wood or resilient channels. 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.

It s not as difficult as it sounds. As i have mentioned many people believe the sound clips and hat channels method to be a more effective decoupling. The procedure shown here is a systematic method for locating the lowest spot on a ceiling then installing the furring strips. Due to its weakness in strength and higher level of flexibility the single leg resilient channel compared to the first single leg resilient channel that gives us most lab test results actually no longer exists.
