Floor Soundproof Kit (HM)

Complete floor sound insulation kit for timber floors

This kit can be used for separating and suspending floors and is particularly effective when you cannot treat the other side because of access issues or neighbouring disputes

  • £120 per Square meter – cost-effective solution
  • Easy to install to a timber frame
  • A High-mass build-up, inclusive of dense cement board, mass-loaded vinyl and a 15mm acoustic underlay
  • Complies with Part E building regulations when installed correctly
  • Suitable for a carpet finish.

This soundproofing kit is high mass, so if you do not have enough room, one of the other kits may be more suitable.

Installation guide

  1. Removing the Floorboards: Start by carefully taking off the existing floorboards to reveal the space between the wooden beams (joists) underneath.
  2. Adding Insulation: Fit the Rockwool RWA45 100mm insulation snugly between the joists, placing it at the bottom of the space you’ve just exposed.
  3. Laying the Structural Floor: Put down the 22mm STS No More Ply board as your new main floor surface. Arrange these boards in an alternating pattern (like bricks), ensuring the ends of the boards are supported by the joists. If needed, add extra small timber pieces (noggins) for support. Use the STS bond adhesive to secure the edges of the boards where they join together. Also, apply acoustic sealant around the edges where the floor meets the walls.
  4. Adding Tecsound Layer: Roll out the Tecsound 100 material over your newly laid STS Board. Make sure the sheets are laid edge to edge, and use joint tape to fasten the seams where the sheets meet.
  5. Setting up Acoustilay Perimeter Strips: Place the Acoustilay 15 strips around the room’s edges, pressing them firmly against the walls or baseboards. Secure these strips by screwing them down through the Tecsound layer into the STS board beneath.
  6. Installing DB Acoustic Underlay: If necessary, glue the DB Acoustic Underlay to the Tecsound using F45 Acoustilay adhesive. Lay this underlay in the same brickbond pattern as before, making sure it’s tightly aligned with the perimeter strips.
  7. Adding Gripper Rods: Attach the carpet gripper rods to the top of the Acoustilay perimeter strips. This setup will align the rod level with the surface of the DB Acoustic Underlay.
  8. Finishing with Carpet: Now, lay your carpet as you usually would over any other underlay.
What does High Mass mean?

The most important factor to soundproofing a room is to add layers of dense mass. In layman’s terms, the thicker the floor the less sound can travel through it.

Do I need to treat both sides of the floor construction?

When it comes to soundproofing floors, particularly separating floors (floors that separate different levels of a building, such as between apartments or different floors of a house), there are specific strategies that tend to be more effective than others.

Insulating both sides of a separating floor is the most effective method to treat sound transmission, but it might not always be necessary or practical based on your circumstances.

If you’re only able to work on the floor from above, there are still options like thick carpets and this type of soundproofing kit.

However, if you have access to the space below and noise is a significant issue, adding insulation and soundproofing elements to the ceiling below can complement what’s done on the floor above, making both layers together more effective in sound reduction.

Can I use this for a wooden floor?

Choosing the right acoustic underlayment for a wooden floor is crucial because wood can amplify both impact and airborne noise. There are several types of underlayments suitable for wooden floors, each offering different levels of sound dampening. When considering a wood or laminate floor finish, your main concern would be compression resistance: You will want something that can withstand the weight of the floor and furniture without compressing too much, as compression can reduce effectiveness.

We have soundprrofing kits that are tested and specified for wood and laminate floors here

Can I tile over this type of kit?

There are only a few products on the market that have been tested to under tiles. One of those is the Acoustilay  Tile Mat. This product is more ridgid than other acoustic underlay materials and you can apply stone or ceramic tiles directly to the mat.

Will this kit help me pass a sound test?

This floor soundproofing solution is designed to exceed Part E Acoustic Building Regulations. So, it’s only the installation that could let you down. The main focus to do your homework on what noises are present and where they are coming from.

Will this kit stop me from hearing my neighbours?

This kit will be a vast improvement to any untreated floor construction and will also help you comply with building regulations.

But its important to note that insulating both sides of a seperating floor will be the best option.

Will this kit stop my neighbours from hearing me?

This kit provides sound reduction in both airborne and impact sound.

There are two types of noise you might be dealing with: airborne noise (like voices or music) and impact noise (like footsteps or items dropping). Different soundproofing methods will address these types of sound differently.

he materials used in the construction of the floor play a significant role in how sound travels. Dense materials can stop more sound, and adding mass can be a way to reduce noise. Components like resilient channels can significantly improve sound insulation by providing a break in the direct path of sound waves.
