PUR/PIR Sandwich Panel for Cold Rooms
High-density insulation with over 90% closed-cell structure. Thicknesses from 50 to 200 mm.
Sandwich panel for cold rooms manufactured with metal sheets (pre-painted steel or stainless steel) and a rigid PUR/PIR foam core. It offers low thermal conductivity, a high closed-cell ratio (over 90%), and strong load-bearing capacity, reducing thermal losses and improving cold room energy efficiency. Its antibacterial, moisture-resistant core makes it suitable for food, pharmaceutical, and logistics environments. Available in thicknesses of 50, 75, 100, 120, 150, 180, and 200 mm, with customizable lengths up to 11.9 m and an effective width of 1,120 mm. Manufactured in accordance with EN 13501 standard for fire reaction classification.

Panel advantages
High thermal performance
Low thermal conductivity reduces energy loss and improves cold room efficiency.
High sealing performance
Over 90% closed-cell structure in the foam core minimizes moisture absorption.
Antibacterial
Moisture-resistant core that prevents bacterial growth, suitable for food and pharmaceutical environments.
High structural rigidity
Strong load-bearing capacity and resistance to deformation, even in large-format panels.
Surface profiles
The outer metal sheet is available in three surface profiles, all with thicknesses from 0.4 to 0.8 mm:
Smooth
Corrugated
Square wave
Coating options
The metal sheet coating is available in four options depending on operating conditions and installation environment:
Standard coating, good cost-to-protection ratio for indoor environments and normal conditions.
Greater durability and weather resistance compared to conventional PE.
Superior resistance to UV radiation and corrosive environments.
Maximum resistance to corrosion, UV radiation, and chemical exposure. Recommended for aggressive environments.
Applications
Custom manufacturing
Each panel is manufactured according to the project's dimensions and thermal requirements. Customizable parameters include: length (up to 11.9 m), panel thickness (50 to 200 mm depending on required temperature range), surface profile (smooth, corrugated, or square wave), coating type (PE, SMP, HDP, or PVDF), sheet thickness (0.4 to 0.8 mm), and sheet material (pre-painted steel or stainless steel). Please inquire about special configuration availability.
