Stud Wall Kit 75mm DFM
Restore peace and quiet by soundproofing stud walls with stud wall kit 75mm. Suitable for stud frames with a minimum depth of 75mm. Use to soundproof new or existing stud walls. Alternatively install this solution on to party walls to increase the sound insulation between neighbouring properties.
Block airborne and impact sound that transfer through poorly insulated walls. Standard stud wall construction does very little to block the passage of sound. This solution will increase wall mass and reduce vibration through the walls structure. The result will be significant noise reduction compared to untreated stud walls. This solution is suitable for rooms divided by light weight internal walls which do not block sound transfer.
Products supplied in Stud Wall Kit 75mm
Stud Wall Kit 75mm comprises of 75mm acoustic insulation which will block and absorb sound waves, therefore reducing airborne sound through the wall.
The soundbreaker bars attached to the stud frame are an acoustic hanger, they will adsorb vibration that would normally transfer through your walls, and this vibration is how the sound transfers between rooms.
The Noisestop 1+ panels combine mass and density to block airborne sound, the combination of acoustic plasterboard and the mass vinyl backing will reduce airborne sound and vibration of the plasterboard.
One layer of 12.5mm acoustic plasterboard, denser than standard plasterboard. Allows you to stagger the joints of the first layer of boards.
AC50 acoustic sealants are used to seal the edges of the boards and around the perimeter of the wall. Using acoustic sealant will ensure no small gaps are left between the boards for sound to escape.
Fitting Stud Wall Kit 75mm
Stud Wall Kits are relatively simple to install and can be carried out by anybody that has a good knowledge of DIY.
The materials supplied within the kits are for one side of a stud wall. If you are soundproofing an existing stud wall remove the plasterboard from one side. If you are building a new stud wall apply the kit to one side of the wall and plasterboard the other side. Use acoustic plasterboard for this as it reduces more sound than standard plasterboard. If you are soundproofing an existing wall you should consider over boarding the other side of the wall with acoustic plasterboard.
Installing stud wall kit 75mm
- Insulate between the stud frame with the DFM acoustic insulation. Cut the slabs 5mm wider than the opening to allow them to friction fit between the stud frame. Ensure the whole are is filled before you move on to the next stage.
- Soundbreaker bars are fitted to the stud frame at 600mm centres. The bars are screwed on to the studs at 600mm centres, horizontally running wall to wall. The first bar is secured 50mm up the wall, continue fitting the bars up the wall. For more information on fitting soundbreaker bars. Bars are fixed into the studs by screwing through the pre-drilled holes that run along the length of the bar.
Fitting soundproof panels and acoustic sealant
- The Noisestop 1+ board and the acoustic plasterboard are screwed directly into the soundbreaker bars. The boards are screwed into the wide flat corrugated flange of the bar. There is no need for pre-drilling into the bars. Attach boards with dry wall screws or universal screws. Fix the Noisestop 1+ panel first and then over board with the acoustic plasterboard.
- Use acoustic sealant to seal the edges of each board and to seal the perimeter of the wall. You can apply acoustic sealant to the panels as you install them, as well as filling any gasp between the boards after they have been installed.
- Once you have installed the boards you can either plaster the wall or tape and fill the tapered edge of the plasterboard.
Reduce flanking noise
When you are considering any form of wall soundproofing you should take into account flanking sound. Sound travels around a building through any cavities it can find. One of the easiest ways for sound to pass through is between floor cavities. Sound transferring through these areas is flanking sound. When soundproofing a wall you should consider reducing the chance of sound transferring through floor cavities between the floor joists.
If your floor joists are shared with a neighbouring property it is easy or sound to transfer through the floor. If you are soundproofing a party wall you should check to see if floor joists are going through to your neighbours property. Do this by checking which way your floorboards are running. If they run in the same direction as the wall the chances are you floor joists will be running into the wall, this will increase the chance of flanking sound transferring between the properties.
The easiest way to reduce flanking sound through your floors is to insulate between the floor joists. Remove a few floor boards up against the wall and fill the cavity against the wall with acoustic insulation 80kg/m³ would be a suitable density of slab to use. Fit the slabs against the wall, coming back into the room approximately 600mm, or the width off a slab.
