Soundproofing your Loft

Posted by NK Lofts Team on 25/01/2016

soundproofing a loft conversion

For those of you considering a loft conversion as a solution to expanding your current living space, there are a few important things to consider beforehand, such as whether to soundproof the new room or not.

Regardless of how you intend to use the room, whether as a playroom for the kids, a home cinema, a gym or even just an ordinary bedroom, without soundproofing the walls, you may be unpleasantly surprised by how much noise can travel in and out of the room.

For those of you seeking a peaceful room to escape from life’s hectic pace, perhaps for a yoga or reading room, you don’t want to be disrupted by the noise from outside traffic, passers by or your noisy adjoining neighbours. Likewise, if you’re planning on being the noisy one in your loft room – perhaps if it’s a music, games or cinema room – then the rest of your household would no doubt appreciate a little soundproofing to shield them from the noise you will be creating in the home.  

Soundproofing your loft conversion isn’t a huge job and won’t set you back, and we can guarantee you will reap the benefits for the rest of your time living at the property – trust us!

How do I soundproof my loft conversion?

Build studded walls over your existing walls – make sure you remember to leave an inch between the two though. Then you can lay soundproofing material, such as acoustic mineral wool, in between the wall and the stud wall and enjoy your peaceful room!

  • Create a frame by attaching horizontal timber battens together, flat on the floor.
  • Once it is built, raise it up and fix to the ceiling and floor (not the walls), and screw in place making sure it is sturdy.
  • Attach the plasterboards from the resilient bars. This will separate the the old wall from the new one.
  • Make sure you screw into the resilient bars only, and not the timber framework.
  • Now the framework is erected, put four inches of soundproof material inside the walls and place the new plasterboard layer over the top.
  • Seal up the joints with silicon rubber or a similar substance.

How does this help soundproof my room?

By following the above steps, you are essentially creating a barrier. Sound has to travel through these materials, so placing an extra barrier in the way will act as a deterrent to noise; similar to how double glazing works. As well as being a barrier against external sound getting into the room, it also works the other way round, and will lock in any sound that is made in the room. The gap you have created between the old wall and the new wall traps in the noise, therefore reducing any high frequencies that you would otherwise hear.
