Highly-engineered German acoustic boards with CE Mark
Can be used for walls and ceilings
These 1200mm x 800mm boards are a superior performance alternative to one of the layers of standard acoustic plasterboard.
The 10mm Phonestar SBX boards is the slim line cousin of the 15mm Phonestar Sbx board it is designed as a high performance addition to all soundproofing systems. It is used to upgrade wall and ceiling soundproofing systems as an alternative to one of the layers of plasterboard.
10mm SBx boards can be used for soundproofing walls and ceilings whether constructed from timber, steel or solid substrate, in new builds, conversions, remedial and refurbishment projects.
SBx boards are an excellent product designed to reduce the transmission of impact and airborne sound between two spaces. The product is our number one choice when trying to improve the soundproofing from noisy neighbours next door or upstairs.
Product Application
SBx Board main applications are in the following:
Soundproofing ceilings
Soundproofing separating walls
Soundproofing party walls
Soundproofing music, cinema and entertainment rooms
SBx Boards are a cross fluted engineered card and hardboard carcass containing a finely mixed and compacted loose quartz sand mixture, which exhibits high mass and density with unique self-decoupling properties.
SBx Boards are a natural product which are breathable, pollutant free and odourless, whilst they are only 10mm thick saving space versus a standard 12.5mm plasterboard. They are easy to cut and install with simple butt joints and does not require flanking strips. This makes for a speedy installation time and low cost of labour, or can easily be completed yourself.
SBx boards offer acoustic insulation which also adds thermal mass to lightweight structures.
Sound insulation performance actually improves by 3dB when a hard surface is fitted on to it and it supports 5kN loading.
This product can be used to very effectively soundproof a wall or ceiling. Ideally it should be used in combination with 60kg/m3 acoustic mineral wool.

The SBX board is used in place of a 12.5mm acoustic plasterboard. The product can be screwed in the same way as plasterboard. Cutting and sealing is done in the same way on both 10mm and 15mm SBx boards.
The boards are labelled with a particular side to be facing outwards. This ensures the product lies consistently from board to board.
Cutting SBx Boards to size
Ensure careful handling to minimise filler spillage – otherwise the final performance may be compromised
Only cut the SBx boards while it is laid flat
Use a straight edge for guidance
Cut with a jigsaw, hand saw, Stanley knife or circular saw (ceramic tile tungsten carbide grit jigsaw blade, or general purpose tungsten carbide fine tooth circular saw blade, for longevity)
Immediately seal all cut edges with PhoneStar SBx Tape while holding the board upright - See below for more details on using SBx Tape

I called Soundstop with lots of questions and the person I spoke with was extremely knowledgeable and helpful. I ended up purchasing soundproofed plasterboards and genie clip system from them
Two alcoves with independent stud walls built and insulation/clips installed.
The result? It works, was sceptical it would,so it was a gamble, sound reduced from neighbours is 70% less and now feel like our semi detached house is more like a fully detached! I’m glad I did it, took me 2 days in total.
All products for a LB2 soundproof ceiling are as expected and delivered on time. The advice given before ordering and before installation was second to none. The guys at soundstop really care that your project goes well. Can't recommend them enough!
From query to delivery always a pleasure to do business with. Can recommend enough. We have used both the standard and advanced (sbx) sm20 systems and they have both made a huge difference in a mid terraced house.
Soundstop are truly amazing at what they do. As a DIYer I need help and advice lots and the team are always there to help out.
The products themselves are top quality and worth of any recording studio never mind my party wall!
Keep up the good work!
The service from the team at Soundstop has been amazing. Jim advised me in the early stages and took my thinking to an end design which is now installed and working beyond my expectations Thankyou
Soundproofing a wall in a factory by a sandblasting booth
The items I have purchased from soundstop have been very useful in the application used to carry out the job requirements on the job that had to be done, the service from Lucy and Jim have been outstanding would use soundstop and would certainly recommend there services to another company or individual
All-round excellent service. Had a phonecall to confirm order minutes after making it online & had further calls keeping me updated on delivery. Very friendly & were more than happy to give some advice when needed.
Genie clips & bars were simple to install & there's good articles on the website for reference. Haven't heard anything from my neighbours yet!
I'd like to thank the team at Soundstop, they completely exceeded my expectations. The customer service is second to none and the delivery was on time as agreed. Very highly recommended.
I don’t think in nearly 23 years I’ve ever dealt with a company so efficient, knowledgeable and helpful! Delivery was very quick. When I needed some technical assistance, Jim was more than helpful. So much so that I felt I should’ve paid him a consultancy fee! Such a pleasure to do business with Soundshield. Amazing!
Very helpful, in helping us to what we needed to order, to soundproof our wall, it all arrived on time, first class service, will be using them again, Thankyou soundproof, for all your help.
My experience of phoning Soundstop for general help with soundproofing and specific help with their products has been a unique experience. A genuine desire to help backed up with the actual knowledge to be so.
I just wish all support calls could be so fruitful.
We had great telephone support whilst choosing the product. We bought Tecsound 70 which was easy to fit ( following the good instructions ) It is a great product and seems to work well. The carpet fitter was amazed by it and the shop are now interested in knowing more! Would recommend both Stopsound and the product
