Key Benefits

• Practical impact noise reduction for concrete floors — 3mm Terrac Rubber Underlayment beneath the overlay board helps reduce footfall and vibration transfer through the floor structure, improving acoustic comfort in the space below
• 10kg MLV mass layer — adds dense mass to the floor build-up to help reduce airborne sound transmission, complementing the impact isolation provided by the Terrac layer
• 18mm STS TG4 structural overlay — creates a stable, level substrate over the soundproofing layers, providing a solid base for the carpet finish
• 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 carpet finishes — the Silent Floor Ultra layer provides acoustic comfort and a suitable substrate directly under the carpet
• 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 37mm excluding carpet; verify door and threshold clearances before committing to this build-up

Important Notes

• This system is designed for concrete floors intended to be finished with carpet
• It is primarily aimed at impact noise reduction; airborne improvements will be more limited compared to full decoupled ceiling systems
• 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. 37mm)
