Noisedeck 27

Noisedeck 27 is an acoustic floating floor, installed over an existing sub-floor that reduces sound transmission between floors. Noisedeck 27 comprises an 18mm moisture resistant interlocking chipboard bonded to a 9m isofiba layer.

Install as a floating floor over most floor substrates, including interlocking chipboard, floorboards and ply-wood sheet. Noisedeck 27 will comply with current Building Regulation Part E requirements when used with a suitable ceiling separating build up.

Use this type of flooring to reduce impact sound transfer in rooms that require floor isolation. Floating floors are used in studios and cinema rooms to minimise sound transfer between rooms.

• Install Noisedeck 27 over existing flooring
• Supports floor loading of 2kN
• Suitable for new build and conversions
• Use on timber and concrete floors
• Compliant to Robust details EFC-1, EFC-2 and EFS-1
• Part E compliant when installed with a suitable separating ceiling structure

• 2400mm x 500mm x 27mm
• Weight 19kg
• 18mm moisture resistant chipboard
• 9mm acoustic Isofiba layer
• Performance
  • Airborne sound 50dB
  • Impact sound 55dB

• Ensure the sub-floor is suitably even, clean and dry to allow the Noisedeck 27 to be laid flat.
• You should install perimeter isolation tapes on the edges of the walls to isolate the boards from the walls.
• Commence the installation of the flooring from the furthest point from the entrance and try to avoid off-cuts of less than 200mm.
• Noisedeck 27 is laid in a broken brick bond pattern with the tongue and groove edges glued together. Avoid mechanical fixings into the joist.

Building Stud Walls

You should install stud walls before laying the Noisedeck 27. Building partition walls before installing floating floors will reduce flanking sound transmission. Isolating the flooring from stud partition walls and structural walls will ensure the soundproofing integrity of the separating floor and the walls.

Skirting Boards and Architraves

Reduce flanking sound by isolating skirting boards and architraves from the flooring. Roll the isolation strip over the flooring and place the skirting board on top. Trim excess tape with a sharp knife. Leave a 2-3mm gap between architraves and the surface of the floor.

Installing Noisedcek boards in Kitchens and Bathrooms

Install kitchen units onto the structural sub-floor. Lay the Noisedeck boards up to the legs of the units. Install the plinth to the legs of the units to finish. Where floor heights need to be changed for white goods etc., use a ply-wood sheet or similar over the sub-floor.

In bathrooms, the flooring should finish at the legs, and the bath is supported from the sub-floor. You should then install the bath panel to finish. Use a ply-wood sheet below the toilet, bath and sink to ensure the floor height throughout.

Noisedeck 27 Fitted Over an Existing Sub-floor

Comply with Part E Building Regulations by installing the Noisedeck 27 using the following ceiling construction method. This system is suitable for timber ceilings.

• Acoustic insulation 100mm/60kg between the floor joists.
• Sounbreaker bars are attached to the ceiling joists.
• Two layers of 12.5mm soundboard plasterboard with a minimum density of 20kg/m²

Alternative solutions that will offer different levels of soundproofing or another kind of installation method that might suit your requirements.

Floor and Ceiling Soundproofing

Make sure you are getting the right soundproofing for your needs. Understanding the most common types of noise and how to stop them will help you decide the right solution.

Different Types of Sound

• Airborne sounds – Conversation, TV noise and radios are examples of airborne sound. The best way to stop airborne sounds is to add mass/density to the walls or ceilings.
• Impact/vibration sounds – Footfall and moving furniture across a floor are examples of impact sounds. The best way to reduce these sounds is to create separation.

In summary, the best way to reduce airborne sounds is by increasing the mass of the area you would like to soundproof. Reducing impact/vibration sounds is achieved by creating separation within the structure.

Reducing Impact and Airborne Sounds

By following some of these steps, you will ensure you get the best level of soundproofing for your room.

• Mass/Density – Increasing the mass and density of the area you are soundproofing will block airborne sounds from transferring between rooms. You will increase the mass of walls and ceilings using materials such as soundproof panels or high-density acoustic insulation slabs.
• Separation – Incorporating separation within the structure will reduce vibration and impact sounds transferring between rooms. Achieve separation by building independent stud walls and ceilings. If you don’t have the space in the room, you can use acoustic clips and resilient channels to decouple the wall and ceiling.
• Absorption – Use materials that are going to absorb sounds. Acoustic insulation is suitable for sound absorption as it converts the sound waves into heat as it passes through the insulation. Dense mass loaded barriers will also dampen and absorb sound. Use acoustic underlays or floating floors to absorb footfall through timber and concrete flooring.
