Market Positioning & Pain Points Solved

The 50 mm panel is the best-selling, cost-effective general insulation roof. Moderate thickness and light weight cut steel-structure load; modular splicing is simple, compressing labor and schedule. Low λ keeps plant/warehouse energy low year-round; concealed lap avoids rain leakage; weather-resistant coating lasts 20+ years - fitting most non-extreme, non-ultra-low-energy buildings.

Application Scenarios

Wide application for PUF roof sandwich panels. Lightweight for steel factories, fast erection for modular buildings, superb insulation for cold storage, anti-weather performance for coastal and agricultural roofs.

Target Markets & Climate Fit

50 mm is the most popular profile: SE Asia factories/warehouses, Middle East heat, Africa prefab camps, S. America coastal with good re-order rates.
Region Why this panel fits

Region	Why this panel fits
Southeast Asia (VN, MY, ID, TH, PH)	Hot & rainy - insulation + waterproof
Middle East (SA, UAE, QA)	Extreme heat/UV - reflective face cuts cooling cost
Africa (NG, GH, KE, TZ)	Light, fast install, low maintenance - prefab/camps
Russia / Central Asia (KZ)	Cold & snow load - low-temp, snow-load capacity
South America (BR, PE, CL)	Coastal humidity/salt-spray - anti-corrosion
North America / Europe	Energy codes & retrofits - high-efficiency, fire-rated

Project Reference

This cold-chain logistics warehouse in Thailand installed our PU sandwich roof panels with a total area of 12,500 m², and the project was completed in 2023. Engineered for tropical high-temperature and high-humidity environments, our PU roof panels offer ultra-low thermal conductivity and reliable waterproof interlocking joints. They maintain a consistently stable low temperature inside the cold storage while effectively reducing refrigeration energy consumption. This panel system has passed inspections in compliance with local building codes, making it an ideal roofing solution for large-span cold storage facilities.

Customization & OEM Service

Standard 50 mm can be tuned: face steel (PPGI/galv/Al/SS), core (standard PU → PIR), RAL color, rib height. Max length 11.9 m for 40ft containers; OEM labeling and matching trims/seal/fasteners available.

Certifications & Compliance

For high-performance building envelopes, our PU sandwich wall products own full ISO management certifications. We source EN-compliant steel substrates to produce panels meeting global building codes.
