PUR/PIR Sandwich Panel for Cold Rooms
High-density insulation with over 90% closed cell. Thicknesses from 50 to 200 mm.
Sandwich panel for cold rooms manufactured with metal sheeting (color steel or stainless steel) and a rigid PUR/PIR foam core. Offers low thermal conductivity, a high percentage of closed cells (over 90%), and good load capacity, reducing thermal losses and improving cold room energy efficiency. Its antibacterial and 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 length up to 11.9 m and a useful width of 1,120 mm. Manufactured in accordance with EN 13501 for fire reaction classification.

Panel advantages
High thermal performance
Low thermal conductivity that reduces energy losses and improves cold room efficiency.
High sealing
Over 90% closed cells in the foam core, minimizing moisture absorption.
Antibacterial
Moisture and bacterial growth resistant core, suitable for food and pharmaceutical environments.
High structural rigidity
Good load capacity and deformation resistance, even in large-format panels.
Surface profiles
The outer metal sheet is available in three surface profiles, all in 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-protection balance for indoor environments and normal conditions.
Greater durability and weather resistance than conventional PE.
Superior resistance to UV radiation and corrosive environments.
Maximum resistance to corrosion, UV radiation, and chemical agents. Recommended for aggressive environments.
Applications
Custom fabrication
Each panel is fabricated to the project dimensions and thermal conditions. Customizable options include: length (up to 11.9 m), panel thickness (50 to 200 mm per 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 (color steel or stainless steel). Consult availability for special configurations.
