Whether transporting refrigerated goods or used for camping and relaxation, the insulation performance of the trailer’s interior is a challenge. Choosing reliable yet affordable structural materials is crucial.

TOPPOLOGROUP offers insulated composite panels for various types of box trailers, including:
- Refrigerated trailers.
- Food trailers.
- Tourist trailers.
- Retail trailers.
- Stage trailers.
- Medical trailers.
- Ice fishing trailers.
- Pet grooming trailers.
- Horse transport trailers.
- Portable toilet trailers, etc.
What types of insulation panels do we offer?
The core material of these trailer insulation panels is closed-cell foam (such as XPS or PU), which has a low density but excellent insulation performance, helping air conditioning equipment to achieve maximum efficiency; the outer layer of the composite panel is weather-resistant FRP (glass fiber reinforced plastic), which can withstand strong outdoor ultraviolet rays and various extreme rain and snow weather.
The most notable features of these insulation panels are:
☑ Lightweight: Facilitates trailer assembly and transportation, reducing the power requirements of the towing vehicle.
☑ Waterproof and moisture-proof: Maintains structural stability and prevents panel performance degradation due to water absorption.
☑ Thermal insulation: Effectively isolates external temperatures, reducing energy consumption.
These composite panels are available in flexible specification
- Maximum size: 12m.
- Maximum width: 3.2m.
- Thickness range: 20-150mm.
- Surface color: RAL or Pantone color chart series.
- Surface treatments: glossy, matte, embossed, etc.
Innovative thermal insulation composite panels
To improve the durability and rigidity of the panels, we also developed thermoplastic FRP (CFRT) as a reinforcing skin. This material is not only more rigid but also more durable, making it suitable for applications requiring higher strength and durability. Furthermore, from an environmental perspective, it is a fully recyclable material.
