Caravans

Travel caravans (camping trailers) used for trips and camping require a lightweight structure resistant to temperature fluctuations, providing thermal and acoustic insulation, as well as an attractive appearance. The caravan body is mainly made of sandwich panels with an XPS foam (extruded polystyrene) or polyurethane core and FRP skins (with gel-coated polyester resin). The roof, walls, and floor are all constructed from these panels, and the joints are sealed with epoxy adhesive and FRP profiles.

Key features of FRP caravans include excellent thermal insulation (warm in winter, cool in summer), no water or moisture penetration (preventing rot and mold), and light weight (reducing fuel consumption of the towing vehicle). Additionally, the glossy exterior surface with integral color (gelcoat) eliminates the need for repainting for over 10 years. Alborz Organic Materials Company supplies specialty resins for caravan panels with high impact resistance (against road debris), as well as structural epoxy adhesives capable of withstanding continuous vibrations.
