JCW Silent Wall Premier System

This system has been designed to dramatically upgrade the sound insulation of existing walls, particularly light weight partition constructions.

Suitable for all types of dwelling it is based on the combination of two highly effective soundproofing wallboards which fix directly to existing walls; JCW Silent Wall, a double pre-laminated sound blocker layer and an additional final layer of JCW Acoustic Plasterboard.

This is a great solution for noisy neighbours and a proven way of complying with Part E of the Building Regulations.

It's a slim and easy to fit acoustic wall system that works by adding mass, a vital component in successful sound insulation, without significant loss of available living space.

For those with extremely noisy situations to remedy, we can also offer our JCW Home Studio Wall System as a complete solution with an even higher acoustic performance

Description

About the system

The main component of this system is a double sound blocker layer of JCW Silent Wall comprising an inner core of 2mm thick JCW Weight Enhanced Barrier Mat which is supplied pre-laminated to an outer layer of 12.5mm JCW Acoustic Plasterboard. Once this double layer has been fixed to the wall, an additional final layer of JCW Acoustic Plasterboard is fixed to provide an impressive acoustic performance result. Because it is so slim and effective, at just 27mm in total, there is little compromise on living space.
It can be applied to either masonry or stud walls and is also suitable to reduce flanking noise up and down walls and will give a 46 dB sound reduction on single brick walls.

The system is light to handle and easy to fit with little DIY experience.

DIY Installation Guide for the JCW Silent Wall Premier System

Incorrect installation techniques and the use of inappropriate materials can compromise the integrity of any acoustic solution. Also all supplied products should be clean, dry and correctly stored prior to work starting. Please follow this general guidance to avoid any incorrect installation which could have an adverse effect on acoustic performance.

Ensure the area being worked is weather tight before installing the acoustic wall solution. JCW Silent Wall soundblocker sheets and JCW Acoustic Plasterboard should only be installed when conditioned to the environment; ideally its moisture content should be the same as can be expected when in service. Avoid starting work if conditions are damp or there is strong evidence of condensation.

It is important that the component elements of this system are always stored flat and great care taken not to damage the edges and corners.

  • Step 1. Ensure the wall to be treated is flat and remove any skirting boards and any coving as appropriate. If the wall surface has been wet plastered earlier, give it a gentle tap. If you get a hollow sound it means the plaster has “blown” i.e. not bonded correctly with the base surface. Chip off the plaster from the affected area, re-plaster and allow to dry before acoustic products are applied.
  • Step 2. Remove any electrical fittings. Only a qualified electrician should do this work. Also use a qualified electrician to re-instate any wiring and electrical fittings etc.
  • Step 3. Start the installation from the bottom left or bottom right corner of the wall
  • Step 4. Offer the first JCW Silent Wall soundblocker sheet to the wall ensuring it is fitted square and allow a 5mm gap around the perimeter edge of the wall
  • Step 5. The sheet should be fixed using 9 drywall screws and plugs evenly placed in 3 rows x 3 screws. Ensure there is a solid fix to the existing wall (each board weighs 22.5 kgs)
  • Step 6. Once the first JCW Silent Wall soundblocker sheet is in position, the next sheet in the bottom row can be butted up to the first sheet – continue this process until all soundblocker sheets are in place in the bottom row – and trimmed as necessary to allow the 5mm perimeter gap
  • Step 7. Boards may be cut with a suitable handsaw and sharp trimming knife
  • Step 8. Start the second row from the end of the first row with staggered joints and continue in this fashion until the fitting is complete
  • Step 9. Fill the 5mm perimeter gap with JCW Acoustic Sealant
  • Step 10. Repeat steps 1 to 9 above to apply the final finishing layer of JCW Acoustic Plasterboard
  • Step 11. The JCW Silent Wall Premier System is now ready for a plaster skim or your choice of other final decorative finish
