R-Board®
R-Board®
Structural. Quiet. Insulating.
The Problem
Over 290 million tires are discarded annually in the United States alone, with more than 1 billion discarded globally each year. Tires do not biodegrade. They accumulate in landfills and illegal stockpiles, creating fire hazards, toxic runoff, and permanent environmental damage.
At the same time, modern buildings rely on materials that provide limited sound insulation, poor moisture resilience, and require multiple layers to achieve comfort and safety.

The Solution: R-Board®
R-Board® converts end-of-life tires into high-performance structural panels for walls, floors, and roofs.
By engineering recycled rubber into a dense composite, R-Board® replaces traditional sheathing while delivering superior acoustic, thermal, moisture, and impact performance.

Engineering & Building Science
Engineered for Real-World Construction
R-Board®️ was designed to fit seamlessly into today’s building practices. It installs using conventional framing methods while providing additional benefits in sound reduction, thermal performance, durability, and sustainability.
Unlike specialty building systems that require new installation methods or specialized tools, R-Board®️ is engineered to work with the products and practices builders already know.

Standard Panel Sizes
R-Board®️ will be manufactured in industry-standard dimensions to simplify adoption.
Standard Panel Sizes
- 4 ft × 8 ft
- 4 ft × 9 ft
- 4 ft × 10 ft
- 4 ft × 12 ft
Available Thicknesses
- ½ inch
- ⅝ inch
- ¾ inch
- 1 inch
Additional custom thicknesses and specialty panels will be available for commercial and industrial applications.
Simple Installation
Installing R-Board®️ requires no specialized equipment.
Builders can:
- Cut with standard circular saws
- Fasten using conventional nails and screws
- Install using existing framing methods
- Finish using conventional siding systems
- Install with standard crews
No retraining required.
No proprietary hardware required.
No special fasteners required.
Recommended Wall Assembly
For northern climates such as Maine, R-Board®️ is designed to work as part of a complete high-performance wall assembly.
Typical assembly:
- Exterior Cladding
- Ventilated Rain Screen
- Water-Resistive Barrier (WRB)
- R-Board®️ Structural Sheathing
- 2×6 Stud Wall
- R-19 Fiberglass or Mineral Wool Insulation
- Interior Vapor Control Layer (where required by code)
- Drywall
This approach combines the structural, acoustic, and thermal advantages of R-Board®️ with conventional insulation systems to create an exceptionally efficient wall.
Air Barrier & Moisture Management
A building is only as efficient as its weakest seam.
R-Board®️ is designed to integrate with industry-standard weather-resistant barrier systems and with R-Tape™️, our recycled elastomeric seam-sealing system.
Together they provide:
- Continuous air sealing
- Moisture protection
- Wind resistance
- Reduced thermal leakage
- Improved acoustic sealing
The result is a tighter, quieter, and more energy-efficient building envelope.
Sustainable Manufacturing
Every R-Board®️ panel helps divert discarded vehicle tires from landfills.
The recycled rubber is:
- Cleaned
- Processed
- Size-classified
- Fully encapsulated inside the composite panel
Because the recycled rubber is permanently encapsulated during manufacturing, it is not exposed and is engineered to minimize odor while delivering superior vibration damping and long-term durability.
Residential Benefits
Homeowners experience:
- Quieter living spaces
- Reduced outside traffic noise
- Better sleep
- Improved comfort
- Lower heating and cooling costs
- Improved durability
- Environmentally responsible construction
Commercial & Multi-Family Benefits
Commercial buildings have different priorities.
R-Board®️ is being engineered to support:
- Improved Sound Transmission Class (STC) performance
- Better occupant privacy
- Reduced vibration transmission
- Lower operating costs
- Sustainable building initiatives
- Enhanced occupant comfort
Fire & Code Compliance
R-Board®️ is being engineered to meet applicable building-code requirements through third-party laboratory testing.
Planned testing includes evaluation of:
- Structural performance
- Fire performance
- Surface burning characteristics
- Air leakage
- Water penetration
- Sound transmission
- Thermal performance
- Long-term durability
Performance data will be published as testing is completed.
Why Builders Like R-Board®️
R-Board®️ doesn’t ask builders to change the way they build.
Instead, it improves the materials they’re already using.
The goal is simple:
- Same framing methods.
- Same tools.
- Same installation process.
- Better performance.
- Less noise.
- Better energy efficiency.
- Greater durability.
- More sustainable construction.
One recommendation I’d add
Why Recycled Tires?
Explain that you’re not using recycled tires just because they’re recycled. You’re using them because rubber has engineering properties that wood alone doesn’t have:
It absorbs vibration.
It reduces sound transmission.
It helps interrupt thermal bridging.
It resists moisture better than wood.
It improves impact resistance.
It keeps millions of tires out of landfills.
That changes the story from “green building product” to “better engineered building product that also happens to be sustainable.” I think that’s a much stronger message for builders, engineers, and investors alike.
Environmental Impact at Scale
Each average home diverts approximately 1,000–1,500 pounds of waste tires
Large-scale adoption could eliminate millions of tires from landfills annually
Reduced material layers lowers embodied carbon and construction waste

Sound Deadening Performance
Assembly comparison
STCReal-world indoor noise reduction near highways is estimated at 20–30 dB, representing a 70–85% reduction in perceived noise.
Insulation & Energy Performance
R-Board® contributes meaningful thermal resistance:
~R-1.5
Rubber composite per inch
~R-3.0
Rubber + textile fiber per inch
Integrated panels reduce thermal bridging and improve building envelope efficiency.
Ballistic-Resistant Option (R-Board® Shield)
R-Board® Shield integrates a ballistic-resistant fabric layer to mitigate small-arms projectile threats. Rubber layers dissipate energy while the fabric captures and spreads impact forces.

Durability & Moisture Resistance
R-Board® does not swell, rot, or delaminate when exposed to moisture. The hydrophobic rubber core resists mold growth and maintains long-term structural stability.
