Key Performance Advantages
Superior Thermal Insulation
Polyurethane foam offers one of the highest insulation values available, with ultra-low thermal conductivity of ≤ 0.022 W/m·K . This minimizes heat transfer, maintaining stable indoor temperatures and significantly reducing heating and cooling costs year-round .
Lightweight with High Strength
Despite their light weight, PU panels deliver exceptional structural performance. The rigid 40kg/m³ PU core bonded to corrosion-resistant steel creates a composite with excellent strength-to-weight ratio . This allows wider purlin spacing and reduced steel structure costs while supporting snow loads and maintenance traffic .
Closed-Cell Structure
The rigid PU foam features a closed-cell structure (≥97% closed cell rate), providing excellent moisture resistance and preventing water absorption . This ensures long-term insulation performance even in humid environments.
Fire Resistance
Our PU panels incorporate fire-retardant additives, achieving Class B fire rating (EN 13501-1) . This slows flame spread and enhances building safety, meeting commercial and industrial code requirements.
Fast Installation
The precision tongue-and-groove joint system enables rapid assembly, reducing labor costs and construction time. Integrated insulation eliminates the need for secondary insulation layers .
