🏗️ Prefab Construction Contractor Reviews
⭐⭐⭐⭐⭐ James Wilkins - Construction Contractor
"We've used Vanjoin's EPS Concrete Sandwich Wall Panels on three prefab house projects now, and the consistency is outstanding. The 150mm Pro Model provides excellent insulation and structural strength—especially important in seismic zones. Installation was 40% faster than traditional methods."

🏡 DIY Prefab Home Builder Reviews
⭐⭐⭐⭐☆ David Lin - Residential Builder
"Building my own prefab home was a big challenge, but these panels made it manageable. I went with the 90mm Base Model for interior and exterior walls. They’re lightweight, easy to cut, and install with basic tools. Only downside—ordering custom thicknesses took two extra weeks."

🏢 Commercial Building Developer Reviews
⭐⭐⭐⭐⭐ Amina Patel - Senior Developer, UrbanBuild Solutions
"We compared several wall systems for a mixed-use development and chose Vanjoin’s Pro Model for its superior fire resistance and load-bearing capacity. After six months of use across multiple sites, zero defects reported. The panels also contributed to our energy efficiency certifications."

🏞️ Remote Site Construction Review
⭐⭐⭐⭐☆ Tomas Reed - Field Engineer, Arctic Research Station
"Used the 150mm panels in a remote, cold-climate build. Their thermal insulation (U-value 0.25 W/m²K) performed exceptionally well. Transport was easier than concrete slabs, and assembly in harsh weather was surprisingly smooth. Would benefit from more on-site technical support during initial setup."
