Untreated stud wall DnT,w

Stud wall with 12mm plasterboard on either side 38dB

Treated stud wall DnT,w

75mm Stud Wall System 57dB

Improvement DnT,w

Noise reduction with treatment 19dB

Note: Every 10 decibels(dB) reduction in noise level is roughly perceived as a halving of the perceived loudness. So, for instance, if you have a sound that measures 70dB and it decreases to 60dB, it would sound about half as loud to the human ear. Decibels explained.

Apply the stud wall soundproofing system to new or existing stud walls.

If you are installing the system onto an existing wall, you must remove the plasterboard from one side of the wall. If you are building a new stud wall, apply isolation strips to the perimeter of the frame.

Reduce potential flanking paths by insulating the floor and ceiling cavity with acoustic insulation slabs.

• Remove the plasterboard from one side of the wall if you are soundproofing an existing wall.
• Use the Isolation Strips around the new stud frame to install a new stud wall.
• Infill the stud cavity with acoustic insulation, ensuring the whole area is filled. If you cut the slabs wider than the opening, they will friction between the studs.
• Fit the soundbreaker bars at 600mm centres and approximately 50mm from the floor and ceiling. The bars are attached to the frame by screwing through the pre-drilled holes.
• Attach the first layer of boarding to the bars using drywall screws through the boards into the wide corrugated flange on the soundbreaker bar.
• Attach the second layer of boarding using the same method, staggering the joints of the first layer where possible.
• When attaching the boards, leave a 3mm gap around the wall’s perimeter, and fill the gap with acoustic sealant upon completion.
• The wall can be finished as with standard plasterboard before decorating.
• Electrical outlets can be installed into the wall, and acoustic putty pads can be used to ensure the acoustic integrity of the wall.

Due to the nature of most of the materials we supply, orders are typically delivered on pallets.

All orders will be wrapped, protected, and secured to the pallet to ensure they arrive in the best possible condition. Goods will be delivered as near to the property as possible. The drivers will not be able to carry orders into your property.
