RC1 - Resilient Sound Channel

Resilient channel is a highly effective and low cost method of reducing the transmission of airborne sound through walls and ceilings. By separating the drywall from the studs, the channel minimizes the direct path by which sound travels through the framing.

Resilient channel is formed from 25 gauge galvanized steel. Using resilient channel in connection with sound attenuation blankets increases the effectiveness of the sound resistant framing.

Resilient channel is installed horizontally at 24" oc. This installation is for framing spaced at 16" or 24". Resilient channel is easily attached with self drilling screws through pre-punched holes.
