Can You Use Rubber Floor Rolls as Insulation?

Thermal Insulation Capabilities

Rubber floor rolls have excellent thermal insulation capabilities due to their low thermal conductivity. This means they don’t easily transfer heat, making them effective at retaining warmth in the winter and keeping spaces cool in the summer.

The secret lies in the tightly-bound electrons in rubber. These electrons are not free to move around, which slows down heat transfer. This makes rubber a great insulator for both electricity and heat.

For instance, EPDM rubber, a popular type of rubber flooring, is known for its low conductivity. It helps maintain a stable indoor temperature, which can lead to significant energy efficiency. This means lower energy bills because your heating and cooling systems don’t have to work as hard.

Rubber flooring is also compatible with underfloor heating systems. This makes it an ideal choice for spaces where maintaining a comfortable temperature is crucial. Whether it’s a gym, workshop, or commercial interior, rubber flooring can help keep the environment comfortable year-round.

Electrical Insulation Benefits

Rubber is not just a thermal insulator; it’s also an excellent electrical insulator. The same properties that make it good at slowing down heat transfer also make it resistant to electrical conductivity.

This high resistance to electricity makes rubber flooring a safe option for environments where electrical safety is a concern. For example, in workshops and commercial spaces, rubber flooring can help prevent electrical accidents.

The safety benefits are significant. Because rubber doesn’t conduct electricity well, it reduces the risk of electrical shocks, making it a safer choice for areas with a lot of electrical equipment or wiring.

In summary, rubber floor rolls offer both thermal and electrical insulation benefits. They help maintain comfortable temperatures and provide a safer environment by reducing the risk of electrical accidents. This makes them a versatile and practical choice for a wide range of applications.

Comparing Rubber to Other Insulation Materials

When deciding on the best insulation material for your floor, compare rubber to other popular options like EVA foam, cork, and Mass Loaded Vinyl (MLV). Each material has its pros and cons, especially regarding R-value, vapor barrier, moisture resistance, durability, shock absorption, cost, sound insulation, thermal properties, and installation.

Rubber vs. EVA Foam

R-Value and Thermal Properties: Both rubber and EVA foam offer insulation, but EVA foam generally has a slightly higher R-value, meaning it provides better thermal resistance. Greatmats‘ tests showed that EVA foam mats were 5-8 degrees warmer than concrete, while rubber tiles were 4-5 degrees warmer.

Vapor Barrier: Both materials act as effective vapor barriers, preventing moisture from seeping through. However, rubber is more durable and less prone to tearing or puncturing.

Moisture Resistance: EVA foam is closed-cell, making it highly moisture-resistant. Rubber also resists moisture well and is less likely to develop mold or mildew.

Durability: Rubber is more durable and can withstand heavy gym equipment and high foot traffic better than EVA foam. Gyms prefer rubber for its longevity and ability to handle heavy weights without damage.

Rubber vs. Cork

R-Value and Thermal Properties: Cork has a higher R-value compared to rubber, making it better for thermal insulation. However, it is not as effective at moisture resistance.

Shock Absorption: Cork excels in shock absorption, making it comfortable underfoot. Rubber also offers good shock absorption but is more durable under heavy loads.

Moisture Performance: Cork is susceptible to moisture and can deteriorate if exposed to damp conditions. Rubber, on the other hand, is impervious to moisture, making it a better choice for basements and other potentially damp environments.

Cost: Cork is generally more expensive than rubber. Given rubber’s durability and moisture resistance, it often provides better value for money.

Rubber vs. Mass Loaded Vinyl (MLV)

Sound Insulation: MLV is specifically designed for soundproofing and is more effective than rubber in this regard. However, rubber still offers decent sound insulation, particularly in gym settings where noise reduction is important.

Thermal Properties: Rubber has better thermal insulation properties compared to MLV, which is primarily designed for soundproofing rather than thermal insulation.

Installation: Rubber flooring is easier to install than MLV. Rubber rolls can be laid down with adhesives or interlocking mechanisms, while MLV often requires more complex installation methods.

In summary, while rubber offers excellent durability, moisture resistance, and good thermal properties, EVA foam and cork provide better thermal insulation but at the cost of durability and moisture resistance. MLV excels in sound insulation but falls short in thermal properties and ease of installation.

Installation Tips for Rubber Floor Rolls

Subfloor Preparation

Before you start laying down rubber floor rolls, it’s crucial to prepare the subfloor properly. Whether your subfloor is concrete or wood, cleaning it thoroughly to remove any dirt, debris, or sharp objects is essential. This ensures a smooth surface for the rubber rolls and prevents potential damage.

For concrete subfloors, make sure they are dry and free of cracks. Any moisture can lead to problems like mold and mildew. If the concrete is damp, consider using a moisture barrier before laying the rubber flooring.

For wooden subfloors, check for any loose boards or nails that could protrude. Sand down any rough spots and ensure the surface is even. This helps in achieving a secure and level installation.

Adhesives and Vapor Barriers

Using the right adhesive is key to a successful rubber floor roll installation. Not all adhesives are suitable for rubber, so make sure to choose one that’s specifically designed for it. A good adhesive will ensure that the floor stays in place and does not shift over time.

Moisture Considerations: When dealing with moisture-prone areas, a vapor barrier is essential. This will prevent condensation from forming under the rubber floor, which can lead to mold and mildew issues.

Combining Materials: If you want to combine rubber with other insulating materials, like foam or cork, make sure to use a subfloor. For instance, you could place a layer of rigid foam insulation over the subfloor, followed by plywood or OSB, and then lay the rubber flooring on top. This method helps distribute the load and offers additional insulation.

Suitable Adhesives

When it comes to adhesives, water-based acrylic adhesives are often recommended for rubber flooring. These adhesives are strong, safe to use, and environmentally friendly. Make sure to follow the manufacturer’s instructions for application to ensure a secure bond.

Preventing Condensation: To prevent condensation, ensure that the subfloor is completely dry before applying the adhesive. You might also consider using a dehumidifier in the room for a few days before installation to remove any excess moisture from the air.

By following these tips, you can ensure a smooth and effective installation of your rubber floor rolls, maximizing their insulating and protective benefits.
