Structure and Definition of EPS Foam Core Panels
At the heart of these composite foam panels is the EPS foam core, known for its rigid cellular structure that traps air effectively. This foam core provides:
- Lightweight construction: EPS is remarkably light, reducing structural load and easing installation.
- High thermal insulation: With low thermal conductivity, EPS minimizes heat transfer, supporting energy-efficient building designs.
- Moisture resistance: EPS offers good resistance to moisture, preventing mold and structural damage.
The outer skins firmly bond to the EPS core, enhancing panel strength and durability while protecting the foam from physical damage and environmental exposure.
Properties of EPS Foam
EPS foam is favored for its combination of important properties:
- Lightweight yet strong: EPS weighs significantly less than traditional insulation materials, decreasing transportation and labor costs.
- Superior thermal insulation: Its closed-cell structure offers R-values typically ranging between R-3.6 to R-4.0 per inch, making it ideal for heat retention and cold storage applications.
- Environmental resistance: EPS maintains performance in humid environments and is resistant to biodegradation.
- Cost-effective: Compared to other foam cores, EPS balances performance with low cost — a key factor for large-scale projects.
Comparison with Polyurethane and Rockwool Core Materials
While EPS shares some benefits with other core options, understanding its strengths relative to polyurethane (PUR/PIR) and rockwool is vital:
Feature | EPS | Polyurethane (PUR/PIR) | Rockwool |
---|
Thermal Insulation | Good (R-3.6 – 4.0/in) | Higher (R-6+ per inch) | Moderate (R-3.0 – 3.3/in) |
Weight | Very lightweight | Slightly heavier | Heaviest |
Cost | Most cost-effective | Higher cost | Moderate |
Fire Resistance | Moderate, can be enhanced | Good, varies by formulation | Excellent, inherently fire-resistant |
Water Resistance | Good | Good | Absorbs moisture if untreated |
Environmental Impact | Recyclable, eco-friendly | Less eco-friendly | Natural mineral-based |
EPS panels strike a balance, especially where lightweight, cost efficiency, and insulation are priorities. They are less expensive than polyurethane and provide better moisture resistance than rockwool.
