Sound Proof Drywall

Sound proof drywall is what we do on a regular basis. We use many different methods to achieve a sound proof drywall. We can even achieve a pre-set decibel level if you wish.

Sound proof drywall using insulation

One of the insulation products we use for sound proofing is Knauf Sound Stop which we use both inside a drywall and on top of a ceiling board. This is one of the most effective products and we test others regularly too. Made from glass-wool it is similar to other brands such as Isover Cavity Batt, Isotherm and Think Pink. There are some brands which design their insulation for both heat and sound. However, some do just one or the other. We measure the strength of Glass-wool products by Density per Cubic metre. The more dense the glass wool the more effective it is. Two of the best insulators are called IM24 and IM475. These products have a density of 24 and 47.5 respectively and are very effective.

Gyproc Soundbloc

Gyproc has a drywall board designed to block out noise called Soundbloc. This board is thicker than the standard board at 15mm and has excellent sound reducing properties. Used in conjunction with an acoustic stud, even better results are achieved. Click here for more details on this product.

Another method of achieving a noise free environment is by building the drywall with 2 layers of board both sides of the frame. This is a common method especially if you need both a 1 hour fire rating and a sound proof wall. Two 30 minute fire boards are used on both sides of the frame. Thereby giving you a 1 hour fire rating as well as a sound proof drywall. For more information on fire rated drywalls click here

As you can see, there are many ways to achieve a noise free room and we have the experts to help you.Bear in mind, if you want to build a sound proof drywall, its always necessary to build it to roof height and not ceiling height. If you build to ceiling height and leave a void in the ceiling, most of the sound will go through that void so its always necessary to build through the ceiling right up until the roof sheets
