A load-bearing, cement particle board for the improvement of airborne noise in flooring systems.


A load bearing floorboard at over double the density of standard P5 chipboards to improve the airborne sound reductions transferring through a floor. Commonly installed on top of our P8 isolation strip a floating floor system can be created. Floating floor systems are some of the highest performing systems for reduction of sound and vibration through floor/ ceiling partitions and when using the STS TG4 boards in place of conventional structural boarding minimal height is added on to the floor build up. The TG4 boards can be installed on timber joist or metal structures with tongue and groove on four sides to give an airtight seal. 

As fibre cement is water resistant, this means the board can also be used in a wide range of applications including: wet rooms, kitchens, outdoor tiled areas, flat rooms, balconies, garden rooms and many more.

The high thermal conductivity of the cement fibre board allows the cement fibre to absorb and release heat much more efficiently than chipboard, therefore enhancing the performance of you underfloor heating.

Further reductions in both impact and airborne sound transmission can be gained by using a suitable MuteMat underlay on top of the STS TG4 boards. The performance can even be further increased with the addition of Tecsound, which will help to further reduce sound and vibration for areas requiring higher levels of performance.

We are always looking for the best ways to describe to you the world of soundproofing through introducing guides that range from the basic principles of sound, how to best soundproof surfaces and what to look for, and how to understand acoustic test data, and this is only naming a few! We want to help you come to the right decision, so whether this is through the use of our guides or talking to a member of our team - we are here to help!

 

How to Soundproof a Floor

 

A combination of the following will always result in a much improved acoustic performance.

  • Mass: Adding mass is one of the best ways at reducing airborne sound and impact sound when de-couples sufficiently. The material of the STS TG4 boards greatly increases the mass over conventional materials.

  • De-Coupling: Separating rigid materials or surfaces through the use of acoustic isolation clips, or isolation strips and lower density layers.

  • Damping: The reduction of vibration through the use of flexible, damping materials such as Tecsound.

STS TG4 Boards are formed from a cement particle impregnated board, this helps to create a significant amount of mass, an important part of the soundproofing process. It is commonly installed in conjunction with removing the existing floor, treating the space (cavities) between the joists and refitting the floor and de-coupled from the perimeter, this is our Perimeter Flanking Band, this will also allow for an appropriate expansion gap for the flooring. You want to prevent Flanking Transmission whenever possible, both in timber and concrete builds, and one example here that installation teams often overlook installing all the flooring layers tightly against the adjacent walls without a buffer. This vibration then has a clear path for transfer into the wall, moving up or down, leading to lesser results, or even the failure of an acoustic test.

With the vast ranges of noises expected in the home or workplace, these often contribute heavily to distractions and disruptions, so it is essential to not only combine all the properties above when choosing a soundproofing system but also to take care of the smaller details. STS TG4 acts either a replacement for chipboard or ply or as an over boarding for large spanning joists. Tongue-and-groove options help to keep the floor airtight, and this is very important for airborne noise, as it will travel through any remaining gaps, even those a few millimetres in width.

 

Combine with our MuteMat 2 or MuteMat 3 to further improve airborne and impact results.

 

We recognise the subjective nature of sound and how we react to each one, and that is why we offer so many variances in our systems. We understand that it is not always possible to incorporate significant losses of space with say, the introduction of a stud frame, so we provide different variances to suit what performance you need, your budget and thickness.

The STS TG4 boards are a direct replacement for conventional structural floor boarding products and materials. The installation of the boards are very similar to a typical tongue and groove flooring installation with a few changes to tools and adhesives, more details can be found below:

Step 1

Step 2

Step 3

Step 4

Cut boards to size Cut STS Construction board TG4 using a circular saw fixed with a vacuum extractor and an STS PCD Saw Blade. This method will cut boards easily and mitigate dust. Boards are fixed with board text facing up.

Stick boards to joists STS Construction board TG4 can be fixed to timber or steel joists installed at maximum 600mm centres. To achieve an acceptable finish, it is important that floor joists are level. Apply a bead of STS Mega Strength PU Adhesive to the joist, then position the first board.

Secure with screws Secure with 12 x 50mm STS Fibre Cement Board Screws, placed a minimum of 12mm from the square edge and 5mm from the side of the joist. Ensure screws are placed a minimum distance of 25mm from the tongue and groove edge.

Apply adhesive to groove Lay in a brick bond pattern. Tongue and groove joins do not need to end on a joist but all square edges should be fully supported. Secure subsequent boards by applying Mega Strength PU Adhesive along the length of the board’s groove, before inserting the tongue of the next board. Ready to tile or install other surface finish immediately.

 

For further reductions in sound the STS TG4 boards can also be installed in a floating floor system.

 

Storage

Boards should be stored and handled in a manner to prevent deterioration and damage. The product should be protected from atmospheric actions, excessive humidity and temperature changes, such as rain, sun, winds and moisture. STS TG4 boards must always be stored flat. If boards are stored outside they must always be fully covered with a waterproof tarpaulin.

 

Acclimatisation

STS Construction Board TG4 must be protected from moisture and weather prior to installation. Although they will not deteriorate after installation even if subject to adverse weather conditions, it is recommended that if this is likely to happen a coat of waterproof primer, such as SBR, will reduce moisture ingress. Before the final finish is laid, boards should be thoroughly cleaned and allowed to acclimatise to the final ambient temperature and moisture conditions of the building. If piped under floor heating is installed this can be turned on to assist with acclimatisation.

 

 

 

The reccomended adhesive for use is the NoMorePly Slow Set PU Adhesive, this will cover aropund 10-12 boards per tube. This is applied using the Foil Tube Applicator Gun.

 

 

Soundproofing products act as a barrier to decrease sound leaving or entering a room or workspace. Sound absorbers absorb the sound within a room and assist to reduce room reverberation etc. Absorbers do not prevent the sound leaving the space but will reduce it. If you are wanting to soundproof a room you would have to buy soundproofing products. It may also be worthwhile to think about some absorbers inside the room to help reduce the sound before it hits the soundproofing.

 

 

A sound barrier is a sound blocker and usually includes insulation with a high mass, which then reduces the amount of sound that can pass through it. A standard domestic door is a good example of a noise barrier when it is closed as it reduces the sound of external noise. Sound waves flow like water and air so it is impracticable to use a sound barrier such as a fence or screen to stop noise but they are effective when used to reduce noise immediately on the other side of them. From distances farther away the noise reduction will be less efficient.
