What is an RC1 channel made of?
CEMCO’s standard RC1 resilient channels are manufactured with a 1-1/4” top flange, and a 1/2” nailing/screw attachment flange, giving the channel 1/2” furring height from the face of the wall stud. RC1 is produced from hot-dipped galvanized steel in standard G40 coating weight.
What is RC-1 resilient channel?
Resilient Channel was originally brought to the mass market decades ago by USG (United States Gypsum). The product was trademarked as RC-1, and tested extensively at Riverbank Acoustic Laboratories. Today many installers, architects and material retailers refer to any channel with one “leg” as RC-1.
What is rcrc-2 channel?
RC-2 Channel is also commonly referred to as resilient channel. Hat track, hat channel and furring channel are not appropriate names for this material. This is a “2 legged” resilient channel that is also unspecified by the SSMA, and absolutely unsuitable for use with resilient sound clips. History of Resilient Channel:
What is RC 1 ProPlus made of?
Made of 22mil steel to provide a stiffer resilient channel (RC-1 ProPlus) is one of the most effective, low-cost methods of improving sound transmission loss through wood and steel frame partitions. It is used as a cross-furring member for resilient attachment of gypsum. Knurled face makes wallboard application easier.
What is RC1 for?
RC1 One Leg Resilient Channels is a low-cost decoupling method used on steel or wooden framed ceilings and walls to separate the structure from drywall, effectively reducing sound transmission.
What does RC channel stand for?
What is Resilient Channel? Resilient channel, also known as RC, is a metal framing material. While it was originally designed for crack suppression for drywall panels, it is now primarily used to change the acoustical properties of walls and ceilings.
Are RC channels worth?
Physics is real, and RC channel used as a sound dampening device is based on those real properties. As long as the RC channels and drywall are installed correctly, they really do work to dampen sound from surrounding areas by not allowing sound waves or vibrations to pass from studs to drywall.
How thick is RC channel?
Resilient channel is available in 18 and 30 mil thicknesses (25-20ga.). Standard channel lengths are 12 foot long.
How do you use an RC channel?

How much RC channel do I need?
For the best results, type in the width and height of each wall or ceiling. The 'height' measurement for the ceiling is the length of the joists. We recommend 24" hat channel spacing for single or double layer drywall and 16" hat channel spacing for triple layer drywall.
Can you put resilient channel over existing drywall?
Hanging RC Over Existing Drywall: When adding a 2nd layer of drywall, this should be done on the other side of the wall. If the resilient channel is installed directly over drywall (rather than studs), it creates a mass-air-mass condition that greatly reduces its effectiveness.
Can I use drywall screws for resilient channel?
drywall board to the resilient channel use 1” (25 mm) Type S Buglehead screws every 12” (305 mm). Screws should not come in contact with the stud, joist or truss. A maximum of two 5/8” (15.9 mm) boards should ever be fastened to resilient channel.
How much does resilient channel reduce sound?
What is this? As far as STC is concerned, sound isolation clips add 15-20 STC on an average. Resilient channels can add 5-7 points. So, if you don't mind investing a little more, it is better to opt for sound isolation clips.
Can resilient channel hold 2 layers of drywall?
Tests conducted by United States Gypsum, a manufacturer of resilient channel, demonstrate that resilient channel can support multiple layers of wallboard.

How many channels do I need for a RC helicopter?
You need 6 channels for electric CP helis and 7 channels for nitro. Any more channels than that only become useful if you want to control something else added on to the heli. ie; lights, retracts, etc. Even if you don't need the extra channel or two though the radio itself may be better.
How many channels do you need to fly an RC plane?
A typical 4-channel rc airplane will have motor, ailerons, elevator and rudder control; the four primary rc airplane controls. There are no set rules as to how many channels an rc airplane can have, it is purely dependant on the plane itself and/or how many functions the pilot wants to control.
What are channels in RC receiver?
A channel is the signal path for each type of message your radio sends to the flight controller. It's a little bit of a carry over from the old days of model RC, but the concept still works. Usually the first four channels are used for roll (aileron), pitch (elevator), thrust (throttle), yaw (rudder).
What is RC1 channel?
RC1 One Leg Resilient Channels is a low-cost decoupling method used on steel or wooden framed ceilings and walls to separate the structure from drywall, effectively reducing sound transmission. Length of each channel measures 8.6' (102").
What is a resilient channel?
Resilient channels are a popular and efficient low-cost method of reducing sound transmission in steel or wooden framed partitions. The Resilient Channel decouples the drywall from the structure, preventing sound from traveling through. For more optimal results, RC Channels can be used in conjunction with RC-1 Boost Clips for a gain ...
Why is it important to install channels properly?
It is essential that channels be installed properly for them to work as intended.
Do you put a channel first?
Yes we advise putting the channel first. Between layers will cause an issue known as the triple leaf effect. When applying the 2 layers onto the channel you also have the opportunity to add a damping compound like G reen Glue between the layers. Read more about the triple leaf effect here.
Can RC channels be used with RC-1 boost clips?
For more optimal results, RC Channels can be used in conjunction with RC-1 Boost Clips for a gain of up to 7 STC points. Important Note: This product is NOT to be used with Resilient Sound Clips, which require Hat Channels for installation.
What is RC-1 material?
Resilient Channel, also known as RC-1. This is considered a “1 legged” material that is often used by itself to try and isolate sound. This is NOT a material specified by the SSMA and therefore there are dozens of questionable designs available in the marketplace.
Who invented the resilient channel?
History of Resilient Channel: Resilient Channel was originally brought to the mass market decades ago by USG ( United States Gypsum). The product was trademarked as RC-1, and tested extensively at Riverbank Acoustic Laboratories.
What is a resilient channel?
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. Over the past 20 years, in both industrial and commercial settings, we’ve found resilient channels installed correctly in the field less often than not, resulting in poor acoustical performance. Below is a list of most common design and installation failures.
Why should resilient channel assemblies be field tested?
As a rule of thumb, Resilient Channel assemblies should always be field-tested to ensure they perform adequately in the field. Due to complex installation requirements and mounting restrictions, field performance often deviates from lab-tested STC ratings.
Can you put RC over existing drywall?
Hanging RC Over Existing Drywall: When adding a 2 nd layer of drywall, this should be done on the other side of the wall. If the resilient channel is installed directly over drywall (rather than studs), it creates a mass-air-mass condition that greatly reduces its effectiveness.
Can RC be used on walls?
Although strong in compression, RC is very weak in tension, and therefore should not be used on walls where heavy units will be mounted, such as TVs, cabinets, or bookshelves. These units will either pull away from the wall over time, or if directly mounted to the studs, will greatly reduce the effectiveness of the Resilient Channel.
Is the resilient channel soundproof?
However, the channel is not visible when screwing in, so it is very difficult to attach the fasteners to the exact spot. If any of the screws go through to the inside flange, the Resilient Channel is now fully locked in, and provides no soundproofing benefit.
