Comparing 50mm EPS Sandwich Panels to Other Insulation Panels
When choosing insulation panels, understanding how 50mm EPS sandwich panels stack up against alternatives like PU (Polyurethane) and rock wool can help you make the best decision for your project.
EPS vs PU Panels
- Cost effectiveness: 50mm EPS panels are generally more affordable than PU panels. EPS uses expanded polystyrene foam which costs less to produce and install.
- Thermal insulation: PU offers a higher thermal conductivity (better insulation) due to its closed-cell structure. However, 50mm EPS panels still provide solid insulation performance with a thermal conductivity range around 0.035-0.040 W/m·K, which is suitable for most U.S. building requirements.
- Durability: Both materials are durable, but EPS tends to resist water absorption better, reducing risk of mold or degradation over time.
EPS vs Rock Wool Panels
- Weight: 50mm EPS sandwich panels are lighter than rock wool panels, making them easier to handle and quicker to install, which cuts down labor costs.
- Cost: EPS is more budget-friendly, especially for large-scale projects.
- Fire resistance: Rock wool excels here with superior fire ratings and the ability to withstand extremely high temperatures without melting. EPS panels do have fire resistance ratings up to B1 or B2, with self-extinguishing properties, but rock wool is the safer choice if maximum fire protection is critical.
- Sound insulation: Rock wool may provide better sound absorption, though 50mm EPS still offers good noise reduction, up to around 30 dB per square meter.
Quick Comparison Table
| Feature | 50mm EPS Sandwich Panel | PU Sandwich Panel | Rock Wool Sandwich Panel |
|---|
| Cost | More affordable | Higher cost | Moderate to high |
| Thermal Conductivity | 0.035-0.040 W/m·K | 0.022-0.028 W/m·K | 0.035-0.045 W/m·K |
| Fire Rating | B1 – B2, self-extinguishing | B1 – B2, limited smoke | A1 – Non-combustible |
| Weight (per sq ft) | Lightweight (~5-7 lbs) | Medium weight (~7-10 lbs) | Heavier (~10-15 lbs) |
| Water Absorption | Low | Moderate | Low to moderate |
| Installation Ease | Very easy due to light weight | Moderate | More labor intensive |
50mm EPS sandwich panels offer a balanced mix of affordability, ease of installation, and reliable insulation performance. For projects where cost and speed matter most—like commercial warehouses, prefab houses, and cold storage—they’re an ideal choice. If fire resistance or higher insulation is a priority, then rock wool or PU panels might be worth considering despite their higher price and weight.
