An Introduction to Soundproofing
Soundproofing walls is an important way to reduce noise in any living space, be it a home, office, studio, or anything in between. It involves creating a physical barrier between the interior and exterior of a building that helps block out sound waves and prevent them from entering the interior space. There are many benefits to soundproofing walls, including:
- Improved acoustic quality
- Extra insulation
- Better sleep
- Enhanced quality of life
- Improved privacy
- A more comfortable and welcoming space
The Best Materials for Soundproofing Walls
Acoustic plasterboard, such as our KNAUF Sound Panel, provides enhanced sound performance and larger density compared to standard plasterboard. Alongside providing an excellent insulating layer, it prevents sound waves travelling in and out.
Products such as our ROCKWOOL Flexi, made from rock mineral wool, can be used in a variety of different applications. The roll offers great acoustic and thermal properties, and is extremely easy to handle and install.
Our ROCKWOOL RWA45 is the ideal acoustic slab product for filtering out noise pollution as its dense consistency helps to block out sound waves travelling around the space. Much like the previous products, the acoustic slabs also provide excellent insulation.
How To Soundproof A Wall:
Our easy-to-read step-by-step guides are designed with you in mind. Discover how to soundproof internal and external walls with the above products, and learn how to become a DIY pro.
DISCLAIMER: This guide acts as a brief outline for soundproofing internal stud walls and external walls. Be sure to consult a professional before starting your project.
Soundproofing an Internal Stud Wall:
Start by gathering the necessary equipment and assessing the wall in question. Make sure it is clean, dry, and free from any cracks or holes that may affect the soundproofing.
If you are working with an existing wall, carefully remove any wallpaper and other coverings from the surface. This will ensure a better seal when applying soundproofing materials later on.
Use the ROCKWOOL RWA45 to line the inside of the wall. This material will absorb sound waves and block noise from transferring in and out of the room.
After measuring, cut the KNAUF Sound Panels into strips and attach them to the frame using screws and washers. Pay special attention to make sure they are firmly affixed so they don’t come loose over time.
Cover the attached KNAUF Sound Panels with a layer of soundproofing material such as ROCKWOOL Flexi which is designed to create a more effective barrier between rooms.
Finally, install drywall on top of all sealed areas for added protection from outside noise sources such as traffic or neighbours. You may also want to add insulation between layers of drywall for added protection from sound vibrations travelling through air ducts.
Soundproofing an external wall:
Ensure you have the correct equipment and make sure the wall is structurally sound with no cracks or holes before you begin soundproofing.
Measure the dimensions of the area you want to soundproof in order to get an accurate number of required materials. Use a pencil to mark the measurements on the acoustic plasterboard.
Carefully cut the KNAUF Sound Panels using a fine-toothed saw - make sure they are snugly fitted against each other when installing them on the wall.
Place a layer of the ROCKWOOL Flexi between each slab before applying it onto the wall with adhesive glue or screws. Make sure that each layer is properly installed so there are no gaps between them.
Apply the KNAUF Sound Panels over your newly-installed ROCKWOOL RWA45 and ROCKWOOL Flexi, sealing any remaining gaps with adhesive tape or caulk.
Using a screw gun or drill, attach drywall screws into studs along the edge of each sheet of plasterboard to secure it firmly in place.
