Key Benefits

• Maximum impact noise reduction for concrete floors — 10mm Terrac Rubber Underlayment absorbs footfall and vibration energy before it enters the floor structure, delivering the highest impact isolation within this product family
• High mass build-up for airborne noise — 10kg/m² MLV combined with a 22mm STS TG4 overlay board adds significant surface mass, improving airborne sound reduction compared to thinner concrete floor systems
• Heavy-duty 22mm STS TG4 overlay — creates a stiff, stable substrate over the soundproofing layers, providing a solid base for the carpet finish while contributing to overall acoustic performance
• Silent Floor Ultra Acoustic Underlay — provides additional impact reduction and comfort directly under the carpet, improving the overall acoustic performance of the finished floor
• Suitable for flats, apartments, and high footfall areas — designed for concrete floor construction above occupied spaces where impact noise from footfall is the primary complaint
• Complete system supply — all components are included in the calculator output except fixings and carpet, so you can order everything needed for your floor soundproofing project in one place
• Built-in 5% waste allowance — calculator quantities include a 5% overage to account for cuts and waste, reducing the risk of under-ordering on site
• Check floor height clearances before ordering — this system adds approximately 48mm excluding carpet; verify door and threshold clearances are sufficient before committing to the Pro build-up

Important Notes

• This system is designed for concrete floors intended to be finished with carpet
• Sealant quantities are an approximation only and should be treated as a guide
• The calculator is provided as a guide only, and final quantities should always be checked before ordering
• Always check floor height/threshold clearances before ordering (this system adds approx. 48mm)
• If doors/thresholds are tight, check clearances before committing to the Pro build-up
