Insulated Panel System
XPS Extruded Polystyrene Board
XPS extruded polystyrene board for cold room floor insulation and building thermal break applications where compressive strength, moisture resistance, and insulation continuity are important.

XPS Extruded Polystyrene Board Engineering Overview
XPS extruded polystyrene board is often used in cold room floor insulation because it has good compressive strength and moisture resistance. It helps reduce heat gain from the ground and protects low-temperature rooms from floor condensation problems.
Unlike wall sandwich panels, XPS is usually part of a floor system. The quotation should consider board thickness, compressive strength, vapor barrier, concrete layer, floor load, drainage, and whether forklifts or pallet jacks will be used.
JiangNan can provide XPS board as part of cold room floor insulation solutions, especially for freezer rooms, warehouses, and projects where floor thermal break is required.
Insulation Performance
XPS helps maintain floor insulation under compression. Correct grade selection is important because weak boards can deform under racks, pallet load, or forklift traffic.
Joint and Sealing
Floor insulation joints should be staggered and sealed by the floor system. Thermal bridges at wall-to-floor connection should be avoided.
Surface Selection
XPS itself is normally not the walking surface. It should be protected by concrete, aluminum plate, stainless plate, or another designed floor layer.
Export Handling
Panel length, stack height, protective film, forklift access, and container loading should be checked before production. This avoids damage during long-distance shipment.

Panel Thickness Selection Guide
The thickness guide below is a practical starting point for cold room quotation. Final selection should consider room size, ambient temperature, door opening frequency, stored goods, product entering temperature, equipment load, and local energy cost.
| Panel Thickness | Recommended Temperature Range |
|---|---|
| 50 mm | +10C to +15C service rooms, processing rooms, or areas with low temperature difference |
| 75 mm | 0C to +10C chilled rooms, fruit rooms, dairy rooms, and beverage rooms |
| 100 mm | -18C to 0C medium-temperature storage or energy-saving chilled rooms |
| 150 mm | -35C to -18C freezer rooms, seafood storage, meat storage, and high ambient sites |
| 200 mm | below -35C or special low-temperature projects after engineering confirmation |
For freezer rooms, floor insulation should be discussed early. Once the civil floor is poured, it is difficult to correct missing vapor barrier or insufficient insulation.
Applications
Seafood Cold Storage
Requires low-temperature insulation, corrosion-aware surfaces, and careful panel sealing around doors and floor joints.
Meat Processing
Needs hygienic surfaces, impact protection, reliable corner connection, and thickness selected for chilled or frozen operation.
Dairy Storage
Usually uses chilled temperature, easy-clean surface, stable panel joints, and good door sealing for frequent access.
Vegetable Storage
Requires correct temperature range, airflow planning, and surface material that can handle humidity and cleaning.
Pharmaceutical Cold Room
Requires stable insulation, controlled access, clean inner surface, and reliable room envelope performance.
Logistics Warehouse
Needs stronger surface options, long panels where suitable, and careful coordination with sliding doors and dock areas.
Manufacturing, Packaging, and Loading Details
JiangNan checks panel production, surface material, joint forming, core bonding, trimming, labeling, packing, and container loading as one workflow. For export customers, this is important because damaged panels, missing accessories, or unclear labels can delay site installation.






Production Control
XPS supply should be checked by thickness, density, compressive strength, board size, packing, and site installation method. Floor design should be coordinated with contractor requirements.
Packaging Control
Panels should be stacked by type and length, protected from surface scratches, and loaded according to container balance. Doors, accessories, corner parts, sealant, and small hardware should be packed separately with labels for site checking.
How to Choose the Right XPS Extruded Polystyrene Board
1. Start with temperature and goods type
Start from floor temperature, room temperature, product load, rack load, and traffic. A freezer floor needs stronger insulation planning than a chilled processing room.
2. Confirm surface material and steel thickness
Confirm whether forklifts, pallet jacks, racks, or heavy carts will operate above the floor. This affects compressive strength and protective floor layer.
3. Check joint type, panel width, and maximum length
Use staggered installation where possible and avoid continuous gaps. The wall-floor junction must be designed to reduce thermal bridging.
4. Match panels with doors and refrigeration layout
Door threshold, drainage, floor slope, and refrigeration defrost water should be coordinated with the floor insulation design.
5. Review packing and installation before production
Pack XPS boards to avoid edge damage and moisture exposure during shipment. Site storage should keep boards clean and protected before installation.

FAQ
What information is needed to quote XPS Extruded Polystyrene Board?
Please send the country, required temperature, room size or panel quantity, panel thickness, steel thickness, surface material, joint type, maximum panel length, and whether accessories or doors are needed. These details allow JiangNan to check production feasibility, packing volume, and container loading.
How should the panel thickness be selected?
XPS thickness is selected by floor temperature, load, insulation requirement, and concrete floor design rather than by wall panel rules only. Thickness should also consider ambient temperature, door opening frequency, installation location, and long-term energy cost.
What steel thickness is available?
Common steel thickness is 0.4 mm to 0.8 mm, with thicker steel available for stronger impact resistance. Stainless steel, color steel, embossed aluminum, or other surfaces can be selected according to cleaning, corrosion, and traffic conditions.
What is the normal PU or insulation density?
XPS density should be selected by compressive strength, floor load, and project specification. Higher load areas need stronger board grade. Density and core quality should be confirmed with the final quotation because insulation performance and panel strength both affect cold room operation.
Can panel length be customized?
Yes. Panel length can be customized according to room height, ceiling span, container loading, and site handling ability. Very long panels reduce joints but are harder to unload and install, so shipping and installation should be checked together.
What joint type is recommended?
Staggered joints and tight installation are important for floor insulation. Gaps can create thermal bridges and condensation risk. The joint must provide tight connection, easy installation, and reliable sealing after the room is in operation.
Can JiangNan provide panel layout drawings?
Yes. For cold room projects, JiangNan can prepare layout suggestions showing wall panels, ceiling panels, corners, door openings, and accessories. This helps the customer count materials and guide installers at site.
How are panels protected for export?
Panels are protected with film, stacked according to thickness and length, and packed for container loading. Small accessories, locks, sealant, hardware, and installation materials should be packed with clear labels and checked before shipment.
Which surface material is best for food cold storage?
XPS is normally protected by floor layers. For wet or heavy traffic areas, the full floor build-up should be designed with vapor barrier and protection. The choice depends on stored goods, cleaning method, humidity, salt, chemical exposure, and impact risk.
Does this product work with JiangNan cold room doors?
Yes. The panel thickness and joint design can be matched with hinged doors, sliding doors, electric sliding doors, and special door frames. Door opening dimensions should be confirmed before panel production.
