SYMBOLS
Made from recycled fibers that would have ended up in the landfill. The
recycled fibers are re-purposed into a high performance underlayment correctly
supporting the floor.
Helps to keep unwanted sound from traveling to other rooms
Best choice for moisture protection. The Ori-Wick® Technology of the fiber
composition wicks away harmful moisture vapor in concrete as well as top side
incidental moisture which promotes dissipation and evaporation. The integrated
vapor barrier protects the flooring from any potential moisture damage.
Crush
resistant fibers properly support a variety of floors including Vinyl Plank,
Laminate, Solid and Engineered Harwood.
Fibers
inherently offer insulation to your floors for better energy efficiency.
Integrated seam tape for fast and easy installation.
Approved
for use with radiant heat system
Impact Sound
Impact Sound Noise created by collisions with the floor
Ambient Sound Noise
Ambient Sound Noise created by talking, electronics etc.
FEATURES
INSTALLATION METHODS
• Floating
• Glue Down
• Mechanically Fastened
FLOATING FLOORS
- Roll out underlayment and flip over so vapor barrier side is facing up and butt seams together
- Apply moisture barrier seam tape, and ensure underlayment seams run perpendicular to the floor covering seams
- Click & lock floating floors over the top according to manufacturer
DOUBLE GLUED DOWN FLOORS
- Double Glue Down installations are approved with flooring that is a minimum thickness of 4mm.
- Roll out underlayment and flip over so vapor barrier side is facing up and butt seams together, ensure seams run perpendicular to the flooring seams
- Adhere to subfloor using pressure sensitive adhesive and recommended trowel size and install method
- Roll over the underlayment with a 75 or 100 pound roller
- Adhere flooring over the top using floor manufacturer’s recommended adhesive and trowel size. Follow all adhesive manufacturer’s instructions for appropriate bonding
MECHANICALLY FASTENED HARDWOOD FLOORS
- Unroll the underlayment and ensure vapor side is up and fibers are to the subfloor.
- Install underlayment in opposite direction to the flooring material. You can tape the seams but it is not necessary.
- Install the hardwood per manufactures written instructions, using their recommended fastening materials.

SOUND PROPERTIES
IMPACT SOUND TRANSMISSION
The method is designed to measure the impact sound transmission performance of a floor-ceiling assembly in a controlled laboratory environment.
| IIC | Flooring | Sub-floor |
|---|---|---|
| 70 | 5mm Vinyl Plank | over a 6” concrete subfloor with a suspended ceiling |
assembly
55| 5mm WPC| over a 6” concrete slab
SOUND TRANSMISSION LOSS
The sound-insulating property of a partition element is expressed in terms of the sound transmission loss.
| STC | Flooring | Sub-floor |
|---|---|---|
| 62 | 5mm Vinyl Plank | over a 6” concrete subfloor with a suspended ceiling |
DELTA
Tests the impact insulation difference between a bare concrete subfloor with no flooring materials and the same concrete subfloor with flooring and underlayment.
| Delta IIC | Flooring |
|---|---|
| 28 | Underlayment under 5mm Vinyl Plank |
LIMITATIONS
Not suitable for use as underlayment for:
- Ceramic tile
- Carpet
- Sheet-vinyl
- VCT
*Commercial applications require minimum floor thickness of 4mm
Installations over concrete in high moisture areas (vapor emission rate above 6 lbs/ 1000 sq ft/ 24 hrs) will require additional protection such as a concrete sealant or polyethylene vapor barrier.
SUSTAINABILITY AND LEED
- Underlayment contains post industrial/pre-consumer fibers.
- Underlayment is LEED TM compliant and will contribute to:
- MRc4.1-4.2 recycled content credit
- EQ 4.3 low-emitting materials credit
- Underlayment is GreenGuard Gold certified
Volatile Organic Compounds (VOC) Meets low emissions standards with zero off gassing.
