Roof Sandwich Panels for Cold Storage Buildings
In steel-framed cold storage buildings, the external roof cladding shields against solar radiation, carries snow and wind loads, and keeps the plenum above the internal cold room ceiling completely dry.

Recubrimiento metálico de zinc por inmersión en caliente que brinda protección catódica al acero.
Núcleo de acero estructural de 0,50–0,60 mm de alto límite elástico que aporta rigidez mecánica y capacidad autoportante.
Capa de galvanizado en caliente que protege la cara interna de la chapa frente a la corrosión.
Capa de pasivación química interna que estabiliza el zinc y mejora la adherencia.
Imprimación especial que asegura una unión permanente con la laca posterior.
Recubrimiento Back Coat que crea un enlace molecular con la espuma PUR/PIR de 40–42 kg/m³, evitando la delaminación ante choques térmicos ΔT.

Preguntas Frecuentes de Ingeniería y Suministro
Preguntas técnicas frecuentes sobre puertas frigoríficas, selección de espesor de panel, sellado térmico y proyectos llave en mano.
C11 Which cold room panel thickness should be selected for each operating temperature regime?
General engineering guideline: 60–80 mm for +8/+15°C cool storage, 80–100 mm for +2/+8°C chillers, 100 mm for 0/+4°C fresh storage, 120–150 mm for -18/-22°C freezers, 150–180 mm for -25/-30°C deep freeze, and 180–200 mm for -35/-40°C blast freezers.
C12 What is the main difference between PUR and PIR insulated cold room panels?
Both provide high thermal insulation at 40–42 kg/m³ density, while PIR (Polyisocyanurate) features an enhanced isocyanurate ring structure that delivers superior fire resistance, reduced smoke emission, and compliance with industrial property insurance standards.
C13 What is the difference between Cam-Lock modular panels and continuous-line slip-joint panels?
Cam-lock modular panels allow rapid assembly and future disassembly/relocation for walk-in cold rooms. Continuous-line labyrinth slip-joint panels are engineered for tall industrial cold storage buildings and long partition walls up to 13.5 meters.
C14 Why is floor insulation critical in cold rooms and freezer chambers?
Without proper floor insulation in sub-zero rooms, ground moisture freezes and expands (frost heave), cracking the concrete slab. Modular rooms use birch-plywood + stainless steel floor panels, while forklift-rated warehouses use multi-layer high-compressive XPS/PIR below a reinforced concrete slab with underfloor heating or ventilation.
C15 Why are hygienic cove skirtings and rounded internal/external corner profiles (A02) required?
Sharp 90-degree wall-to-floor and wall-to-wall angles trap bacteria and organic residues. HACCP, IFS, and BRCGS food safety audits require coved (rounded radius) PVC/aluminium hygienic profiles for effortless sanitation.
C16 Which cold rooms require a pressure relief valve (A03)?
Rapid air contraction after door closure or defrost cycles creates strong vacuum pressure inside sealed rooms. Heated pressure relief valves are mandatory in all sub-zero freezers and blast rooms to prevent panel implosion and vacuum-locked doors.
