In modern construction, impact noise and vibration control have become essential for creating comfortable living and working environments. Among many materials, cork rubber underlays stand out for their unique combination of natural cork elasticity and rubber durability.
So, how do you choose the right one for your project? Here’s a quick professional guide 👇
1️⃣ Identify Your Application
ApplicationRecommended ThicknessPurpose🏠 Residential floors2–5 mmReduces footstep noise, improves comfort🏢 Commercial / Office buildings5–10 mmMinimizes structure-borne sound🏋️ Gym / Industrial areas10–20 mmStrong shock & vibration absorption🎧 Studios / Golf simulators10–15 mmExcellent low-frequency isolation
2️⃣ Key Performance Indicators
- Density: 600–950 kg/m³ → higher density = stronger sound insulation..
- Compression Set: ≤10% ensures long-term resilience under load.
- Moisture Resistance: Choose SBR or EPDM based types for anti-mold protection.
3️⃣ Installation Tips
- Keep subfloor clean, level, and dry before installation.
- Use moisture barrier film when required.
- Floating installation for residential use; adhesive bonding for heavy-duty setups.
- Seal edges properly to prevent sound bridging. Installation Tips
- Ensure the subfloor is clean, flat, and dry.
- Use moisture barrier film if needed.
- For residential use: floating installation under flooring.
- For heavy-duty use: adhesive bonding and sealed joints recommended.
✅ Summary Recommendations
Gym / Equipment area: ≥15 mm, high rubber content for impact absorption.
Residential: 5 mm cork rubber, medium density, with moisture protection.
