EPS UNDERLAYMENT
TECHNICAL DATA
EPS (expanded polystyrene) Underlayment is a closed cell, lightweight and resilient rigid underlayment used in construction underlayment and industrial applications.
EPS insulation products are engineered to give you, the architect, specifier, contractor or building owner, control of the project’s application: from design assistance and timelines, to material and cost options.
The advantages and versatility of using EPS Underlayment products include:
- It has a 50-year proven history
- State-of-the-art equipment to produce an energy efficient underlayment, that meets or exceeds R-Value Code Requirements
- Variety of densities, thickness and sizes
- Unlimited fabrication possibilities
- Dimensionally stable rigid underlayment, no bowing or cupping, no shrinkage and or loss of strength
- Mechanical and Thermal Properties have been thoroughly tested by independent 3rd party laboratories
- There is no Thermal Drift of EPS underlayment R-Value
- 20-year Thermal Performance Warranty
- Has no Ozone Depleting CFC’s, HCFC’s, HFC blowing agents, dyes or formaldehyde
- EPS is the only rigid underlayment manufactured with recycled content that qualifies for LEED points
- EPS underlayment can be manufactured with an inert additive that deters termites and carpenter ants
- EPS underlayment does not sustain Mold and Mildew growth
- EPS is 100% recyclable.

Technical Data
EPS Underlayment meets or exceeds physical and thermal property standards
as established in ASTM C 578
*R means resistance to heat flow. The higher the R-value, the greater the insulating power.
Federal Trade Commision requires usine the R-Value publication at 75F temperature when calculating R-Values of all underlayment
Aged R-Values of alternative products should be compared to determine long-term benefit. Some types of underlayment lose their R-Value over time.
EPS has a flame spread index of 20 and a smoke developed index of 150-300 when tested in accordance with ASTM E84/UL 723 for densities from 0.7 – 3.0lb/ft.
Underlayment Consideration:
DO NOT COMPARE polyisocyanurate conditioned R-Values by RIC-TIMA and PIMA to EPS R-Values as per ASTM C-578
Ask for a 20 year 100 % R-Value Warranty.
EPS Underlayment offers the Best Underlayment Value Per Dollar than any material available today.
Features:
- Low Moisture Absorption: EPS underlayment closed cell structure prevents capillary absorption of water and moisture. As density is increased, moisture resistance decreases, but is still minimal.
- Permeability: EPS has a low permeability, but is not considered a vapor barrier.
- Inert: EPS experiences no physical or chemical breakdowns over time. No nutrient value to animals, insects, or organisms. No nutrient value to bacterial growth including mold.
- No Leachates: EPS will not contaminate the surrounding environment.
- Design Flexibility: EPS can be fabricated into various shapes and sizes as needed.
Design Cautions:
- Flammability: EPS is combustible and should not be exposed to fame or other ignition sources. EPS should be covered with a thermal barrier or otherwise installed in accordance with applicable code requirements.
- Solvent Damage: EPS is susceptible to damage by petroleum based solvents and their vapors. Protect with vapor barrier covering and or use compatible adhesives when applicable.
