75mm PIR Sandwich Panel Laminar Flow Ceiling – 0.4mm Steel Facings, Heavy-Duty OR Ceiling System

Product Introduction
This laminar flow ceiling features a high-density 75mm polyisocyanurate (PIR) core with 0.4mm pre-coated steel facings on both sides. Designed for operating rooms requiring superior structural integrity and thermal performance, it combines an extra-thick insulation core with a built-in unidirectional airflow system, providing a ready-to-install solution that meets demanding cleanroom standards.

Key Features

• 75mm PIR Core + 0.4mm Steel: The thicker 75mm PIR foam delivers exceptional thermal insulation, enhanced dimensional stability, and increased load-bearing capacity; 0.4mm steel plates on both sides ensure reliable flatness and impact resistance.

• Integrated Laminar Airflow: Pre-engineered to accommodate HEPA filter modules with uniform airflow, achieving ISO Class 5 or higher cleanliness in the critical surgical zone.

• Superior Fire Safety: The 75mm PIR core offers Class‑A fire performance with minimal smoke emission, exceeding international hospital safety code requirements.

• Seamless Hygienic Surface: Anti‑bacterial steel finish resists microbial adhesion and withstands repeated cleaning with aggressive hospital-grade disinfectants.

Applications

• Large-scale operating rooms (orthopedic, cardiac, transplant surgery)

• High-traffic surgical suites requiring enhanced durability

• Cleanrooms with strict temperature and humidity control demands

Customization

• Available in multiple panel dimensions and filter coverage areas (e.g., 2.4m × 1.8m, 2.6m × 2.4m, 3.0m × 2.4m)

• Optional integration with LED surgical lighting interfaces, gas service columns, and medical utility pass‑throughs

• Customizable steel facing colors, coating specifications, and reinforcement options

Summary
This system delivers a heavy-duty ceiling solution that merges enhanced structural integrity, superior thermal performance, laminar flow capability, and hygienic design into one modular assembly, ensuring long-term reliability even in the most demanding surgical environments.
