150mm PU Sandwich Panel — Thermal Strength and Durability
150mm PU sandwich panel is a strong, insulated wall system made of two steel sheets with a thick polyurethane (PU) foam core. That extra-thick layer delivers superior thermal insulation, high strength, and excellent soundproofing — perfect for cold rooms, food factories, prefab houses, and container homes.
“When panel thickness jumps from 100 mm to 150 mm, heat loss can drop by nearly 40%.” — Journal of Building Physics, Elsevier 2024
Most 150 mm PU panels use a 38–42 kg/m³ foam density, giving an R-value of about 6.5 m²·K/W. With proper sealing and installation, they can last over 30 years, making them a smart, low-maintenance alternative to brick walls.
150mm Fire-Rated Sandwich Panel Price Singapore — Built for Safety
Fire safety is crucial in Southeast Asia, especially Singapore where codes are strict. A 150mm fire-rated sandwich panel with PIR or Rock Wool core easily meets EN 13501 B1/A1 and FM standards, ensuring resistance to flames and preventing dripping or melting.
| Core Type | Fire Rating | Thermal Value | Avg. Price (USD/m²) | Notes |
|---|---|---|---|---|
| PU | B2 | 6.2 m²·K/W | $18–22 | Standard projects |
| PIR | B1 | 6.8 m²·K/W | $20–26 | Most popular in Singapore |
| Rock Wool | A1 | 5.9 m²·K/W | $22–30 | Top fire protection |
Asia Construction Review (2025) notes that most new warehouses in Singapore now use PIR or Rock Wool panels ≥150 mm to comply with updated fire codes.
150mm Sandwich Panel Factory Direct Price China — Real Numbers You Can Trust
China remains the global hub for factory-direct sandwich panels. 150mm PU or PIR panels range from $11–22/m² FOB Tianjin or Qingdao, depending on steel thickness (0.4–0.6 mm) and coating (PE or PVDF).
“Over 60% of Asia’s PU/PIR panels thicker than 100 mm now roll out of automated factories in northern China.” — Global Prefabrication Outlook, MIT Press 2025
Bulk buyers often receive 2–5% logistics discounts, and CIF shipping to Southeast Asia typically lands around $25–28/m².
150mm Sandwich Panel Price Philippines — Designed for Tropical Climates
The Philippines’ hot and humid climate demands PU or PIR panels with moisture-proof coatings. Prices average $12–24/m² depending on surface finish and coating. Projects in Cebu, Davao, and Manila often select PIR ≥150 mm for cold-storage warehouses to prevent mold and maximize efficiency.
“Energy savings of 38% were achieved when switching from EPS to 150 mm PU/PIR systems in Manila industrial zones.” — Philippine Energy Review, 2025
150mm Insulation Sandwich Panel Price Export FOB — Balancing Cost vs Freight
| Route | Container | Cost Impact | Notes |
|---|---|---|---|
| FOB Qingdao → Singapore | 40 HQ | +$0.8/m² | ≈7 days at sea |
| FOB Shanghai → UAE | 40 HQ | +$1.2/m² | ≈12 days |
| FOB Tianjin → South Africa | 40 HQ | +$1.5/m² | ≈14 days |
Rock Wool cores are about 18% heavier, increasing freight costs.
“Every extra 1 mm of panel thickness boosts insulation 1.3% but also raises logistics cost 0.7%.” — Construction Materials Economics Journal, 2024
150mm Roof & Wall Sandwich Panel Cost — Easy Install, Big Payoff
Modern 150 mm roof and wall systems use hidden-fastener joints for a clean, watertight finish. Average installation speed: 800–1000 m² per day with a 3-person crew.
| Spec | Recommended | Why It Matters |
|---|---|---|
| Steel Thickness | 0.5 mm | Tougher, more rigid |
| Coating | PVDF | UV and corrosion resistance |
| Joint System | Hidden lock | No visible screws, no leaks |
| Thermal Bridge | ≤ 0.04 W/mK | Improved energy efficiency |
“Using 150 mm PIR roof systems cuts HVAC energy use by about 35% in tropical zones.” — Energy-Efficient Building Systems, Elsevier 2024
150mm Rock Wool Sandwich Panel Price — Fireproof & Soundproof
When safety and noise control come first, Rock Wool panels lead the pack. They’re A1 non-combustible, block up to 45 dB of noise, and withstand 1050 °C for two hours.
| Application | Best Option | Avg. Price (USD/m²) |
|---|---|---|
| Factory Walls | Rock Wool A1 | 20–28 |
| Commercial Kitchens | PIR B1 | 22–30 |
| Studios & Offices | Rock Wool A1 | 24–32 |
“Rock Wool cores stayed intact for two hours at 1000 °C with no melting or collapse.” — European Fire Materials Report, 2024
150mm Sandwich Panel Technical Comparison — Performance vs ROI
| Core Material | R-Value | Fire Rating | Lifespan | Price Level |
|---|---|---|---|---|
| PU | 6.5 | B2 | ≈ 25 yrs | Medium |
| PIR | 7.0 | B1 | ≈ 30 yrs | High |
| EPS | 3.8 | B3 | ≈ 15 yrs | Low |
| Rock Wool | 5.9 | A1 | ≈ 35 yrs | High |
“PIR cores retain about 7% more insulation after 10 years than PU foam.” — Journal of Thermal Construction Materials, 2025
Final Thoughts — Why the 150mm Sandwich Panel Price Pays Off
The 150 mm sandwich panel balances cost and performance perfectly. While it costs more upfront than 100 mm panels, its 25–40% energy savings, longer lifespan, and strong fire rating make it a top investment for modular homes, warehouses, and industrial projects.
