Your Soundproofing System Calculator
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 bonded LVT finish
- SilentCork3 Acoustic Underlay with Mapei VS90 adhesive system — SilentCork3 provides additional impact reduction and a suitable bonding surface for the LVT finish, and is compatible with the Mapei Ultrabond Eco VS90 Plus adhesive included in the system
- Low-profile 29mm build-up — a compact Essential-tier alternative to the Pro system, suitable where floor height or threshold clearances are a limiting factor
- Suitable for bonded LVT installations — the SilentCork3 and Mapei VS90 combination provides a bonded LVT-ready substrate as part of the complete system
- Complete system supply — all components are included in the calculator output except fixings, 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 29mm; 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 bonded LVT
- 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. 29mm)
- Always follow the adhesive and flooring manufacturer's guidance for installation and curing times
Installation Summary
- Ensure the concrete floor is clean, dry, and reasonably level
- Install 10kg MLV
- Install 3mm Terrac Rubber Underlayment
- Install 18mm STS TG4 overlay boards
- Tape joints and seal perimeter gaps with AC95 where required
- Install SilentCork3 Acoustic Underlay
- Use Mapei VS90 adhesive to bond LVT as per manufacturer instructions
