Application

Our Insulated Polyurethane Panels fit steel factory outer walls, logistics warehouses and cold storage. They also serve prefab workshops, commercial buildings and cleanroom partition projects for fast construction.

Project Reference

This food manufacturing plant in Poland adopted our PU sandwich wall panels as exterior enclosure. Total panel area reaches 8,200 m² and finished construction in 2019. The 100mm PU core panels deliver outstanding thermal insulation and air-tight performance, minimizing cold bridging and stabilizing indoor temperature for food production workshops. The panels meet European EN standards, resisting humidity and corrosion in temperate climate. Fast onsite assembly greatly shortened construction cycle for this industrial building.

Customization & OEM Service

Flexible customization of length, thickness and RAL color reduces on-site cutting waste. Stable raw-material stock and full-automatic continuous production keep unified strict QC even for non-standard specs, ensuring insulation, compression and sealing performance. We accept sample and small-batch orders and guarantee delivery dates.

Certifications & Compliance

For reliable building envelopes, our PU sandwich wall products own complete ISO certifications covering quality, environment, occupational health & energy management. We strictly follow EN standards for steel substrates to deliver compliant panels for global clients.

FAQ

Q: How to maintain stable quality for bulk projects?

A: Automated constant-temperature curing ensures uniform flatness, bonding and insulation parameters batch by batch, delivering reliable quality for large high-standard engineering.

Q: Is PU core A1 non-combustible?

A: PU core is B1 self-extinguishing, not A1 non-combustible. Select rock wool panels if your project requires A1 fire rating.
