Resilient channel (RC) is a cost-effective and remarkably effective solution for improving sound transmission loss in walls and ceilings. Its simple design, consisting of a lightweight, perforated metal channel, belies its significant impact on reducing noise transfer. This article delves into the world of resilient channel, focusing specifically on the single-leg variety, a popular choice for DIYers and professionals alike. We will explore its applications, installation, pricing, and where to source this versatile soundproofing material.
Understanding the Mechanics of Resilient Channel
The magic of resilient channel lies in its ability to decouple the drywall or other facing material from the underlying framing. Unlike directly attaching drywall to studs or joists, resilient channel creates an air gap. This air gap significantly reduces the transmission of sound vibrations. When sound waves hit the drywall, instead of directly transferring energy to the framing, the energy is dissipated through the air gap and absorbed by the surrounding materials. This results in a noticeable reduction in sound transmission, improving the overall sound insulation of the partition. RC Deluxe, a high-performance variant, further enhances this effect, offering superior soundproofing capabilities at a reasonable cost.
Resilient Channel Sizes Chart
Resilient channel is available in various sizes, primarily determined by its width and thickness. While specific dimensions may vary slightly between manufacturers, the common sizes and their applications are outlined below. Note that this is not an exhaustive list and you should always consult the manufacturer's specifications:
| Size (Inches) | Width | Height | Typical Application |
|---|---|---|---|
| 15/16" x 1 5/8" | 15/16" | 1 5/8" | Standard residential and light commercial applications |
| 1 1/8" x 1 5/8" | 1 1/8" | 1 5/8" | Heavier duty applications, potentially offering slightly better sound isolation |
| Custom Sizes | Varies | Varies | Available upon request for specialized projects |
It's crucial to select the appropriate size based on the thickness of your drywall and the overall soundproofing goals. Consult a soundproofing specialist or review manufacturer guidelines for optimal results. The size chart provided is a general guideline; always check the manufacturer's specifications for precise dimensions.
Where to Buy Resilient Channel
Resilient channel is readily available from a variety of sources. This makes it an accessible solution for both large-scale construction projects and DIY home improvements. Common retailers include:
* Home Improvement Stores: Large home improvement chains like Home Depot, Lowe's, and Menards often carry resilient channel, usually in their soundproofing or insulation sections. However, availability may vary depending on location and stock.
* Building Supply Stores: Local building supply stores specializing in construction materials often have a wider selection and potentially better pricing than large chains.
* Online Retailers: Online retailers like Amazon and specialized soundproofing suppliers offer convenient purchasing options and may offer competitive pricing, especially for bulk orders.
* Specialty Soundproofing Companies: Companies specializing in acoustics and soundproofing are excellent resources for purchasing resilient channel and obtaining expert advice on installation and application.
