Why Interlocking Rubber Tiles Destroy Foam Tiles in Your Gym Build

If you are designing a home gym or a commercial fitness space, the flooring you choose is the foundation of your success. You might be tempted by the dirt-cheap prices of foam puzzle mats, but let's be honest, those foam tiles can actually set you back in your budget. In this guide, we will examine the main differences between interlocking rubber tiles and foam tiles.

By the end, you will have a better understanding of why rubber tiles are far superior to foam tiles and how you always get what you pay for.

The Materials: Recycled Rubber vs. EVA Foam

Understanding what your floor is made of is the first step to building a resilient workout space.

The Power of Recycled Rubber

RFS interlocking rubber tiles are made from recycled tire rubber. This post-consumer material is an eco-friendly and sustainable component in the manufacture of rubber flooring. Every year, millions of pounds of vehicle tire rubber are recycled instead of being discarded in landfills.

The Flaws of EVA Foam

In contrast, interlocking foam tiles and other foam products are made primarily from EVA - Ethylene Vinyl Acetate. While often called "foam rubber" due to its feel, it is actually a plastic copolymer. Foam tiles are not biodegradable and contribute to microplastic pollution when broken down. EVA foam can also release toxic emissions like formamide (used for softness), and mainstream recycling does not exist as a disposal option.

Performance and Durability: Heavy Lifting Requires Heavy Duty

When you drop a dumbbell or load up a squat rack, your floor needs to fight back.

Load-Bearing Capacity and Impact

When it comes to durability, there is no argument. Recycled rubber tiles outperform foam tiles in every aspect. Rubber tiles resist tearing, cracking, gouging, and deformation from heavy weights and high impact. They will maintain their structural integrity under heavy weights and static gym equipment.

Foam, on the other hand, compresses easily and eventually will crush and break down under continual use. Weight benches, weight plates, and even dumbbells can cause permanent indentations. Foam is too soft to adequately disperse the concentrated impact load of a dropped weight or dumbbell. The force of the dropped weight is transmitted through the foam tile and to the hardwood floor below it, which can result in dented, scratched, or cracked wood.

Safety and Traction

Safety should never be compromised. Recycled rubber tiles provide better natural traction and slip resistance (even when wet), which greatly improves safety.

EVA foam tiles are either smooth or oftentimes have a textured or patterned surface molded to help add more grip and traction. Unfortunately, the raised surface is still made from the same closed-cell material and can be extremely slippery when wet.

The Separation Anxiety: Do Your Tiles Stay Together?

A massive issue with lightweight floors is movement. One 8mm thick foam tile will weigh less than one pound, whereas a rubber tile of the same size and thickness will weigh about 6.5 pounds.

Unlike recycled rubber tiles, foam tiles lack the mass, weight, and grip to adequately stay locked together during exercise. Side-to-side, or lateral movement, can create enough force to shift the tiles and pull the interlocking tabs apart. Repeated stress on the foam causes the tiles to flex and deform at the joints. Rubber tiles have more mass and rigidity to stay connected.

The True Cost of "Cheap" Floors

You might see a package of large foam tiles that can cover approximately 19.26 square feet costing about $21.00, or $1.09/sqft. It sounds like a bargain until you realize foam tiles may only last a year or two depending on your daily use.

Recycled rubber tiles in the same thickness and slightly larger coverage area (24 square feet) sell for about $56.00, or $2.34/sqft. However, rubber tiles can withstand decades of heavy use and continual foot traffic without breaking down or losing their shape. With cheap foreign-made foam tiles, you will have to purchase and replace multiple sets of worn-out tiles that will cost you more money over the long term.

Beware of "rubber-topped foam tiles" as well! These are like putting lipstick on a pig. The price per square foot is over TWICE the amount of a solid recycled rubber tile of the same thickness at RFS. The better long-term value will always be recycled rubber tiles.
