herein; , Claims:I/We Claim:

1. A system (100) for thermal insulation composite sandwich structural FRP panel for light commercial vehicles, wherein the system (100) comprises:
a light commercial vehicle (302) configured to utilize a thermal insulation composite sandwich structural FRP panel;
characterized in that, the light commercial vehicle enclosure is made using the thermal insulation composite sandwich structural FRP panel.

2.The system (100) as claimed in claim 1, wherein the thermal insulation composite sandwich structural FRP panel comprises a gel coat (102), a resin infused Glass Fibre Reinforced Plastic (GFRP) (104), a Polyurethane Foam (PUF) (106) and a resin infused Glass Fibre Reinforced Plastic (GFRP) (108) an outer layer.

3.The thermal insulation composite sandwich structural FRP panel as claimed in claim 2, wherein, the Polyurethane Foam (PUF) (106) acted as a thermal core with a thickness ranges from 10 mm to 200 mm.

4.The thermal insulation composite sandwich structural FRP panel as claimed in claim 2, wherein the resin infused Glass Fibre Reinforced Plastic (GFRP) (104) & (108) a thickness ranges from 1-3 mm bonded externally on both sides of the Polyurethane Foam (PUF) (106).
5.The thermal insulation composite sandwich structural FRP panel as claimed in claim 2, wherein the resin infused Glass Fibre Reinforced Plastic (GFRP) (108) is optionally coated externally with a top coat, a weather proof coat that used as the UV protection layer.

6.The thermal insulation composite sandwich structural FRP panel as claimed in claim 2, wherein the gel coat (102) is a thin visible inner layer of light commercial vehicle (302) made of applying paint on the either side or one side of the resin infused Glass Fibre Reinforced Plastic (GFRP) (104) & (108).

7.The system (100) as claimed in claim 1, wherein the thermal insulation composite sandwich structural FRP panel, the total thickness of the thermal insulation composite sandwich structural FRP panel ranges from 12 mm to 205 mm.

8. The system (100) as claimed in claim 1, wherein the light commercial vehicle (302) enclosure of 6 sides front side, back side, left side, right side, top side and bottom side are made up of thermal insulation composite sandwich structural FRP panel.

9.The system (100) as claimed in claim 1, wherein the light commercial vehicle (302) enclosure of front side is made up of thermal insulation composite sandwich structural FRP panel or with the option of hybrid laminate structural composite panels.

10.The light commercial vehicle (302) as claimed in claim 8, wherein the light commercial vehicle (302) with thermal insulation composite sandwich structural FRP panel offers thermal insulation protection from cold temperature (-30°C) to elevated temperature of 60°C with a reduction of temperature gradient of at least 10°C depending on the environment and applied insulation thickness.
