Soundproof drywall is a type gypsum board that blocks nearly all audible sounds from entering a room when installed. Unlike other soundproofing alternatives, soundproof drywall does not use special construction techniques, particular insulating materials, or wall floating materials to achieve soundproofing. Instead, soundproof drywall is a direct replacement for regular gypsum board that is applied directly to the studs.
Soundproofing materials are measured with a metric called sound transmission class, or STC. An average wall in your home likely has an STC rating of 40 or less. This means that most sounds like your neighbors television are low and muffled, but still audible. It is also generally accepted that any wall with a rating over 50 will block most sounds. Soundproof drywall can increase your walls STC to over 55 without any extra insulating techniques.
Benefits of Soundproof Drywall
Soundproof drywall is extremely beneficial for a number of reasons.
- Even though its not required, soundproof drywall allows you to open your walls and increase the quality and amount of insulation in your walls and even add extras like foam pipe insulation to increase energy efficiency.
- It is very difficult to “short circuit” soundproof drywall. Most soundproofing techniques like floating a wall on the studs can easily be ruined by putting one screw into the wrong place, transferring all vibrations. Soundproof drywall can be installed just like regular Sheetrock cutting down risk and labor costs.
- There are very few soundproofing methods that can achieve the results as a single sheet of soundproof drywall. If you are really looking to effectively block unwanted noise, soundproof drywall is the way to go.
The primary disadvantage of soundproofing drywall is the cost. With the average cost of soundproof drywall costing as much as 9-10 times as much as a regular sheet of gypsum board, soundproofing even one room can be very costly.
When it comes to enjoying your home, soundproof walls go a long way towards being able to relax without neighbor’s noise or even loud kid’s music getting in the way. It seems like the benefits of wall soundproofing with soundproof drywall just might just outweigh the extra cost involved to install it in your home.
