Insulation is central to the refrigerated truck design. It plays a vital role in protecting perishable goods. Insulation materials for refrigerated trucks must provide high thermal resistance to prevent outside heat from affecting the interior temperature.
Refrigerated trucks often use multiple layers of materials for their wall panels, roof panels, floors and door panels. It helps achieve optimal thermal insulation and structural strength.

Common Materials Used in Refrigerated Truck Bodies Include:
- FRP (Fiberglass Reinforced Thermosetting Polymer)
- CFRT (Continuous Glass Fiber Reinforced Thermoplastic Laminate)
- XPS (extruded polystyrene) foam core
- PU (polyurethane) foam core
- Multi-layer reinforcement materials (FRP panels, foam core, plywood, non-slip composite flooring, etc.) for flooring
- Embedded aluminum tube, glass fiber composite tube or high-density PU rod
- Aluminum or stainless steel for accessories
FRP provides a strong outer layer that can withstand abrasion, impact, and weather with minimal impact on the truck’s weight, while XPS and PU foam effectively reduce heat transfer from the outside.
FRP Sheet XPS Foam Sandwich Panel
The outer layer is made of FRP sheet, which has excellent durability and lightness to withstand the harsh external environment.
The core material is made of XPS foam. It is an affordable and very effective insulation material that minimizes heat exchange between the inside and outside.
FRP Sheet PU Foam Sandwich Panel
Fiberglass PU foam sandwich panels are another widely used material. They provide excellent insulation for refrigerated trucks.
Its core is made of PU foam, which is particularly good at keeping temperatures low for long periods.
The fiberglass layer increases durability and resists impact and environmental damage, extending the truck’s life and reliability.
