In today’s real estate construction industry, homes are constructed using a variety of materials. When it comes to walls and floor-ceilings the material includes sheetrock, drywall and plasterboard. Generally these materials are installed to both sides of a metal or wooden frame. While these may be standard materials and components, they are one of the primary reasons behind noise pollution within homes.
How do Homes Suffer from Noise Pollution?
With the exception of the drywall or sheetrock, there is no internal structure within the metal frame. Drywall is usually made from Gypsum, which is not capable of deflecting or absorbing sound to a great extent. When sound waves strike the wall, it causes the drywall to vibrate. It’s mounting stud structure allows the vibrations to seep through them and to the other side drywall and reradiates into the home. Hence, it is important that the walls and ceilings of a house be constructed using sound proofing components as it is difficult to do this later. One such component is resilient channel.
What are Resilient Channels?
A resilient channel is a thin metal channel, with a profile like a hat with wings. It is designed to isolate the drywall panels from the frame. The inherent function of the channel is to act as a kind of shock absorber. It absorbs the sound vibrations before they can seep into the home through the interior wall. The channel is installed after the basic sound blocking mat is installed over the studding. Resilient channels can be installed easily during the construction of a home, not afterwards unless the studs are still exposed.
The Importance of Using Resilient Channels
Resilient channels are a part of the range of soundproofing products provided for homes. They are an improved solution as compared to previous soundproofing methods. Let us compare the two.
In the old method, a floor or ceiling would consist of 6 materials:
- Carpet Pad
- Resilient metal channels
- Wood furring
- Sound absorption mat
With few materials that absorb sound, the walls/ceilings would be prone to sound leakage.
New Method: The new methods consists 7 sound absorbing materials:
- Carpet and pad (Floors)
- Mass loaded vinyl (MLV)
- Subfloor gap sealant and visco-elastic coatings
- New style metal (Hat) channel with sound clips (Walls/Ceilings)
- Sound Isolation Padding tape
- Cut wool fibers
- Recycled Cotton Batting
Floor-ceilings also receive additional padding from the drywall and carpeting. The combination of the materials in the new method ensures that a house will not suffer from excessive noise pollution.
Resilient channels is one of the superior soundproofing products, largely replaced with more modern soundproofing products that are more effective but also more costly, which can eliminate excess noise pollution. There are a variety of soundproofing products to choose from depending on the level of sound control desired.
