Stud Wall Kit 50mm DFM

Restore a quiet calmness to your home by soundproofing your stud walls with this acoustic wall kit. It’s suitable for stud frames with a minimum depth of 50mm and can be used to soundproof new or existing stud walls. Alternatively, install this solution on to party walls to increase the sound insulation between neighbouring properties.

Once installed on your walls, these materials 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.

Stud Wall Kit 50mm comprises of:

The 50mm acoustic insulation will block and absorb sound waves, reducing airborne sound through the wall. Then, the soundbreaker bars attached to the stud frame serve as an acoustic hanger to will adsorb vibration that would normally transfer through your walls. It is this vibration that allows sound transfer between rooms.

Our Noisestop 1+ panels combine mass and density to block airborne sound. The combination of 12.5mm acoustic plasterboard and the 10kg mass vinyl backing will reduce airborne sound and vibration of the plasterboard.

Each layer of 12.5mm acoustic plasterboard is denser than standard plasterboard. Using it allows you to stagger the joints of the first layer of boards. Then, 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.

Airborne Sound Insulation

Installing Stud Wall Kit 50mm

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.

To install this stud wall soundproofing kit, follow these steps:

  • 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.
  • 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.

How will my order be delivered?

The majority of orders we despatch are sent on pallets. We use a network of pallet distribution companies across the UK. All our pallet deliveries are kerbside deliveries. This means the pallet will be delivered as near to the delivery address as possible. Pallets are unloaded form the vehicles with a pallet truck. If it is possible the pallets can be dropped on driveways if they are accessible with the pallet truck.

Pallet deliveries are normally made on 7.5 tonne vehicles that are similar in size to bin lorries. Occasionally larger vehicles are used. If you know of any reason why it might be difficult to deliver to your address with this type of vehicle please let us so we can pass the information on to the delivery company. Typical delivery problems can include parking restrictions, access issues for certain size vehicles, low bridges and overhanging trees. Call 01423 339163 if you are unsure.

Unfortunately the delivery drivers will not bring the goods into your property or unload the individual items from the pallets.

Many of our items are heavy and often require two people to carry them safely.

All orders sent on pallets are wrapped and secured to the pallet to protect them while in transit. Once you have received your order we would recommend storing the materials inside. If you are planning on leaving your goods outside you should use additional covering to protect them from any adverse weather conditions.

Damaged or missing items

In the unfortunate event that items are damaged or missing when your order arrives you should sign damaged or missing items on the drivers paperwork. Call 01423339163 to let us know of the issue to allow us to quickly rectify the problem.

We might ask for a picture of the damage, this is to speed up the process of arranging a suitable solution.

To enable us to quickly resolve any issues with your delivery it is important that you sign for your delivery when it arrives.

Special delivery note if you order soundbreaker bars as part of a wall or ceiling kit

If you order a wall or ceiling soundproofing kit that include soundbreaker bars these will be delivered separately from the pallet. we are not able to despatch the bars with the pallet. The soundbreaker bars are too long to go with the pallet so they will be delivered separately. No additional charges are incurred for the separate deliveries. We try to ensure the pallet and the bars arrive on the same day, occasionally this might not happen. Normally both deliveries are made within 24 hours of each other.

*All prices displayed are exclusive of VAT @ 20%. This will be added at the end of the checkout process before you confirm your order.
