What panel thickness for a freezer room?

For –18 to –25 °C use 150–200 mm PIR; for deep-freeze –28 to –30 °C or hot climates use 200 mm. Chilled rooms typically 80–120 mm.

PIR is the default for cold storage — same thermal conductivity as PU (~0.022 W/m·K) but far better fire class (B-s2,d0) and self-extinguishing behaviour. PU is cheaper but rarely accepted by insurers for large stores.

What fire rating do insurers require?

Most European and GCC insurers now require B-s2,d0 core and EI 30 to EI 60 wall assemblies. FM Global 4880 approval is the benchmark for large distribution centres.

How fast can ColdMatch source panels?

Standard PIR ranges quote in 1–2 weeks and deliver in 4–8 weeks. Custom colours, large widths or specialised fire assemblies add 2–4 weeks.

How should a insulated sandwich panels project be planned before requesting quotes?

Define the project scope first — capacity, temperature ranges, throughput, site constraints and required certifications — then use that scope to brief suppliers. Sending vague enquiries produces quotes that can't be compared. ColdMatch is supplier-neutral: we help structure the project before matching it to shortlisted vendors worldwide.

What drives the budget of a insulated sandwich panels project?

Capacity, refrigerant strategy (NH₃, CO₂, HFO or hybrid), automation level, envelope quality, controls, redundancy and site-specific factors like power availability and climate. Country and logistics also matter. Use the ColdMatch cost benchmarks and infrastructure builder to model a realistic range before financing conversations.

What is a typical timeline for a insulated sandwich panels project?

From concept to commissioning most commercial cold-chain projects run 9–24 months: FEED and RFQ (2–4 months), procurement and long-lead equipment (3–6 months), civils and installation (4–10 months), commissioning and validation (1–3 months). Complex pharma, ASRS or transcritical CO₂ projects can extend further.

What are the most common mistakes buyers make on insulated sandwich panels projects?

Buying equipment before defining the project, under-sizing refrigeration load, ignoring commissioning and validation, single-sourcing without a neutral bid comparison, and treating financing as an afterthought. ColdMatch provides planning checklists, RFQ templates and a supplier-neutral tender flow to avoid these traps.

What is insulated panels best for?

Insulated panels suit: New cold rooms, warehouses and processing halls needing envelope supply; Re-cladding or replacing degraded panels in an operating facility; Projects with a specific fire rating or food-contact requirement; Bulk area purchases where price per m² and lead time matter.

When is insulated panels not the right fit?

Insulated panels are not the right category for: Complete turnkey refrigeration projects (use design-and-build); Small repair jobs and single-panel replacements; Structural steel or civil works only.

What information do suppliers need before quoting insulated panels?

Prepare the following before requesting quotes: Wall, ceiling and floor area in m² per temperature zone; Required panel thickness or target U-value; Core material preference (PIR, PUR, mineral wool) and fire rating; Facing material, finish and hygiene requirements; Supply-only or supply-and-install; Delivery port/site and required date.

Project-first

Plan the insulated sandwich panels project before choosing suppliers

Complete cold-chain outcomes depend on planning, budget realism, timeline discipline and neutral bid comparison — not on picking equipment first.

Project planning checklist

Cover the fundamentals before you brief suppliers.

·Define capacity, temperature bands and throughput
·Confirm site, power, water and permits
·Choose refrigerant strategy and automation level
·Set redundancy, monitoring and validation targets
·List required certifications (GDP, HACCP, BRC, ISO)
·Agree budget envelope and financing route

Buyer briefing — specifying cold room panels

How is panel thickness chosen for a cold room?

Thickness follows the temperature difference across the envelope and the ambient climate, not the room size. Chilled rooms at 0 to +5 °C typically use 80–120 mm PIR; frozen rooms at -18 to -25 °C use 150–200 mm; blast and deep-freeze duty and hot ambients push to 200 mm. Under-specifying thickness shows up as continuous plant running and condensation on the cold face, not as an immediate failure.

How much do insulated metal panels cost per square foot?

As a 2026 planning figure, insulated PIR/PUR panels run about USD 28–55 per m² of panel area, which is roughly USD 2.6–5.1 per square foot supplied. Thin 80 mm chilled panel sits at the low end; 150–200 mm frozen panel with FM-approved core and thicker facing steel sits at the top. Installation, doors, profiles and sealing typically add 40–80% on top of the supplied panel rate, and the envelope as a whole usually represents 12–18% of total cold store project cost.

What has to be specified besides the panel itself?

Joint and cam-lock system, vapour barrier and sealing detail, facing steel gauge and coating for washdown or corrosive environments, wall-to-floor and wall-to-ceiling profiles, maximum unsupported span and suspension method for ceilings, fire class and assembly rating, and floor insulation with under-slab heating for frozen rooms. Joints and penetrations, not panel faces, are where most envelopes actually leak.

How do panels, doors and floors interact?

Doors are the weak point in any envelope: specify insulated door leaves matched to panel thickness, heated frames for frozen rooms, and rapid or strip protection where traffic is high. Floor build-up must include insulation, vapour barrier and — for frozen rooms — a heater mat or ventilated void to prevent frost heave lifting the slab over time.

What information do panel suppliers need to quote?

Room dimensions and clear height, temperature per room, ambient design conditions, core type and fire class required by the insurer, wall and ceiling areas, door schedule, span and support arrangement, delivery port or site, and whether installation is in scope. Quotes on m² alone are not comparable without the door schedule and fire specification.

Information suppliers need to quote

•Country, project location and site status (greenfield or existing building)
•Application and product stored or processed
•Required temperature range and any humidity requirement
•Storage capacity (m², m³ or pallet positions) and daily throughput
•Ambient/design climate conditions at site
•Available power supply and backup or redundancy requirement
•Preferred refrigerant, if already defined by policy or regulation
•Indicative budget range and target commissioning date
•Insurer or regulatory fire class required (e.g. B-s2,d0, EI 60, FM 4880)
•Wall, ceiling and partition areas plus clear height
•Door schedule with types, sizes and traffic
•Whether supply-only or supply-and-install is required
