This flooring solves noise and vibration issues by converting impact energy into harmless heat. Our engineered rubber gym tiles use a high-density, viscoelastic core to dampen structure-borne vibration and greatly reduce loud impact sounds.
Noise is a major problem in fitness spaces. I see two types of noise. The first type is airborne noise. This is sound waves traveling through the air. The second type is structure-borne vibration or noise. This is kinetic energy or impact traveling through a solid material like concrete. Concrete and wood easily transfer this impact, which creates loud noise downstairs. Our solution focuses on this second type of energy. Rubber is inherently better than hard materials because of its viscoelasticity. This property allows the material to act like both a solid and a liquid. When a weight drops, the rubber does not just bounce the energy back. It slows the impact. This converts the kinetic energy into a tiny amount of heat. This process is called vibration dampening. It stops the impact energy from reaching the floor below. As an engineer, I focus on maximizing this energy conversion rate to build a truly quiet space. This is how we ensure maximum noise control in heavy free-weight zones. The specific density and molecular structure of our rubber compounds are the result of extensive R&D, ensuring optimal energy absorption under peak load conditions.

We developed a complex structure to control both sound types effectively. The science of dampening requires more than simple material selection. Read on to see how our specific engineering choices make a real difference in performance.
How Does Our Dual-Layer Structure Stop Sound Transmission?
Our tiles use a dual-layer composite structure to manage energy. The top layer handles surface wear and airborne noise. The high-density base layer focuses on absorbing and isolating the heavy structure-borne noise from impacts.
To deliver superior acoustic performance, we use a dual-layer composite structure. This structure allows each layer to do a specialized job. The top layer is the wear layer. We often use EPDM or a custom PVC compound here. This layer is tough. It resists heavy traffic, abrasion, and provides excellent grip. It also helps absorb some of the initial sound waves (airborne noise), which cuts down on echo and reverberation inside the gym space. The base layer is the critical part for heavy impact. It uses high-density recycled rubber granules. Its purpose is purely vibration isolation.
Material Properties for High-Performance Dampening
The performance of this base layer relies on precise engineering of two properties: density and hardness.
| Property | Value (Example) | Function in Dampening |
|---|---|---|
| Density | 900 to 1050 kg/m³ | Mass helps absorb and slow kinetic energy transfer. |
| Hardness | 65 ± 5 shore A | Optimized balance: soft enough to cushion, hard enough to support heavy equipment. |
For many of our 15 mm tiles, we engineer the base layer to achieve a density of at least 900 kg/m³. This mass helps stop the energy. The Shore A Hardness of 65 ± 5 is not accidental. It is the sweet spot. A softer tile feels nice but can tear under impact. A harder tile transmits too much vibration. We chose this range to absorb the kinetic force of a dropped 100 kg barbell without collapsing or letting the shock pass through. This is the core manufacturing expertise we bring to product design. We match the density to the application to ensure both performance and durability. This technical optimization is crucial for long product life.

We must measure performance to ensure quality. It is not enough to talk about materials. The real test is how these properties translate into verifiable, industry-recognized performance metrics.
What Specific Metrics Guarantee Impact Sound Reduction?
Impact sound is measured by the Sound Improvement Rating (Lnw). This number shows the reduction in impact sound transmission compared to a standard bare floor. Our best-performing tiles achieve an Lnw 61 dB rating.
When we talk about stopping noise, we rely on certified technical data. The most important metric for structure-borne noise is the weighted normalized impact sound pressure level reduction (Lnw). This number is used by building codes. It tells us the difference in sound transmitted through a ceiling (the floor above) when our tile is installed. A higher reduction number means a much quieter floor below.
Analyzing Sound Improvement Rating
For our 15 mm composite rubber gym tile, the data shows exceptional performance:
| Tile Thickness | Density | Sound Improvement Rating | Practical Meaning |
|---|---|---|---|
| 15 mm | 900 kg/m³ | Lnw 61 dB | Extreme reduction of impact noise for heavy weight areas. |
| 20-30 mm | 1050 kg/m³ | Lnw 50 dB | High reduction for very heavy, concentrated load zones. |
I always recommend we look at Lnw. The 61 dB rating for our 15 mm tile is excellent. It is a critical data point for a product developer. It proves that the combination of 900 kg/m³ density and the dual-layer design works exactly as intended. When a client needs to place a free weight zone over office space, I can provide this data. This allows them to meet strict building sound codes. We use this technical detail to guide clients. It ensures the floor is not just durable but legally compliant and functional in complex building applications. This focus on performance data makes us a technical partner, not just a supplier. The 50 dB rating for the thicker, denser tiles is also excellent. We recommend this for extreme powerlifting areas.

Performance in the lab must equal performance on site. Let us look at how this advanced vibration isolation technology provides tangible benefits in the most demanding real-world environments.
Can Rubber Gym Tiles Truly Protect Subfloors and Satisfy Neighbors?
Yes, the dense, elastic tiles stop impact energy from damaging the structural subfloor and prevent noise from traveling to tenants below. Our tiles are essential for managing free weight zones in multi-story or mixed-use buildings.
Our core manufacturing expertise is about solving real-world design problems. The performance metrics translate into two key benefits in real-world applications: structural protection and tenant satisfaction.
Real-World Benefits and Design Optimization
When designing a gym, especially for an upper floor, protecting the subfloor is critical. Repeated, heavy impacts from dropped weights can cause cracks or structural fatigue in concrete over time. Our cushion layer acts as a buffer. It absorbs the peak force of the impact. This protects the integrity of the underlying concrete or structural deck.
| Application Scenario | Engineering Challenge | Solution via Tile Design |
|---|---|---|
| Free Weight Zones | High peak force; loud structure-borne noise. | 15 mm minimum thickness; Lnw 61 dB rating; high density core. |
| Multi-Story Buildings | Noise transmission to lower floors; tenant complaints. | Vibration isolation achieved by the viscoelastic base layer. |
We often advise developers working on mixed-use properties. Noise is the number one complaint. Installing a high-performance rubber gym tile is a much cheaper solution than major structural acoustic treatments. Our tiles, especially the 500 x 500 mm and 1000 x 1000 mm options, are designed for easy, seamless installation. This is a clear example of how our manufacturing knowledge supports better final design and cost control. We do not just make a product; we optimize the solution for the specific structural challenge. We provide the technical guidance needed for the best result. The base layer’s 65 ± 5 shore A hardness is intentionally firm. This prevents the flooring from becoming too spongy under heavy machine loads, maintaining stability while isolating vibration.
