Phonestar SBx Boards - 15mm
£32.95
SBx can be used for soundproofing walls, floors 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 downstairs.
Many customers get confused by the large array of heavy rubber mats on the market which are great at stopping impact sound transmission traveling downwards but are less effective at the more common problem that affects people, that is the airborne sound being transmitted upwards. Due to it's "fluid mass" content, SBx boards can be twice as effective at reducing airborne sound transmission as the heavy 15kg mats available on the market.
38dB (Rw, -5Ctr) Airborne sound insulation, this is manufacturer tested data of the product in isolation, 22dB (;Lw) Impact sound insulation (manufacturer data).
Product Application
SBx Board main applications are in the following:
Soundproofing floors
Soundproofing ceilings
Soundproofing separating walls
Soundproofing party walls
Soundproofing Home Cinema and Entertainment rooms
SBx Boards are a cross fluted engineered card and hardboard carcass containing a "fluid mass" that is 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, the boards are only 15mm thick which avoids problems with door thresholds and re-fitting skirting in refurbishments. 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 it also works seamlessly with under floor heating.
The solution gives comparable sound insulation results to robust floating floors which are a minimum 107mm thick. It provides a solid floor feel underfoot unlike other squashy acoustic floor systems.
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 floor. Ideally it should be used in combination with 60kg/m3 acoustic mineral wool.
This is a true DIY solution with the only skill necessary being the ability to cut (then tape and seal) the SBx boards.
