For the 18mm Sandwich kits of Liderkit Group the sidewalls and frontwall consist of LIDERfoam® panels 18mm thick.
These panels are made of polyester skin reinforced with fiberglass (2 mm thick for both faces) and extruded polystyrene foam as inner core.
This kit has the ”2-pieces profile system”, without external sealing or rivets, which makes the assembly faster and easier. Even though there are no rivets or visible sealing, the rigidity and the water resistance of the kit are completely guaranteed.
It is also possible to insert kickplates and cargo track systems, as well as additional options like side doors or windows.
